The Central Inland Fisheries Research Institute during
the year continued its research efforts to understand
production functions in our inland aquatic resources
viz , rivers, reservoirs. estuaries and wetlands for
developing management norms. The issues related to
resource assessment on GIS format including monitoring
and management of fish and ecosystem health were also
addressed. In order to generate required database and
provide policy support the institute worked on eleven
research projects covering different theme areas The
institute also took initiative to create awareness about
biodiversity and ecosystem conservat~on among the
fishers who depend upon the fishing activities along
rivers and estuarine systems Attempts were also made
to demonstrate varlous fishery enhancement techniques
to different user groups operating in wetlands
Our co-operation with Fishery Department In the states
of West Rengal. Gujarat. Karnataka. Assam. Haryana.
Uttar Pradesh grew from st~ength to strength The ClFRl
through a Govt of India sponsored project has been
deeply involved in GIs application in flshery resource
assessment with thirty-five States and Union Territories.
Th~s is one of the massive efforts in fishery resource
assessment in inland flshery sector in the country. The
ClFRl also partictpated actively in network projects with
sister institutes, SAUs and other research organizations.
At the international level two programmes, with the
support from World FA Centre. Pemng, Malaysin, were
executed satisfadaily and another progmmme spommed
by CP-IWMI, Colombo is being executed. Post Tsunami
information was provided to authorities on mangroves
by CIFRI, for inclusion in mangrove b ad restoration
action plan for affected coastal areas. The Institute
remained committed to generate internal resources and
to achieve the target set by the Coundl and we met the
target by performance of scientists and technidans. With
regard to NEH activities, the lnstitute executed the
a p p d work programme sattsfactody with main focus
on fisheries enhancement from floodplain wetlands. As
a part of our special effort on awareness, different
publications were released during the year and sixteen
exhibitions and farmer's day were organized.
All mandatory meetings of Research Advisory Committea,
Staff Research Council, Managanent Committee, Institute
Joint Staff Council, were held as per schedule and action
were taken as per their suggestions for research and
institute management.

Director

The Central Inland Rsheries Reseanh lnstitute (CIFRI)
was established in March 1947 initially as a research
center and later up scaled to the level of full-fledged
institute. Over the years, the organization has grown
and established itself as a premier institute in the field
of inland fisheries in the country. The Institute is located
at Barrackpore, Kolkata in the State of West Bengal.
The lnstitute at present has sixty scientists, eighty-three
technicians, seventy-one administmtive staff and hundred
sixty supporting personnel. The institute had a total
budget of Rs 202.06 lac for the year 2006-2007.
The Institute organized its research programmes as per
the guidelines of the high level Research Advisory
Committee (RAC), comprising mostly of eminent
professioh from the field of fishery and aquatic ecology.
The programmes were so designed that philosophy of
VISION 2020 and recommendations of last QRT were
kept in view, apart from directives received from the
SMD and Council from time to time. The lnstitute also
has a Management Committee guiding its activities A
number of internal committees such as Staff Research
Council, lnstitute Joint Staff Council. Official Language
Committee, Consultancy Processing Cell etc. are in
place and contributed in Institute's management activities
through period~c meetings and decisions taken.
Continuing our efforts, the lnstitute during the year
focused its attention on overall performance, which
involved research, transfer of technology, internal and
external human resowre development, public awareness
programmes, establishment of linkages and institutional
building activities.
The research programmes are designed with major
thrust on ecosystem research involving resource base
assessment, ecology, biodiversity, fish stock evaiuation
including yields and environment monitoring and its
management. During the year the lnstitute woTked on
eleven research programmes apart from nine externally
funded projects and three internationally funded ones.
went achievement under various progmmme areas are
highlighted as under :
Riverine Fisheries
The chemical and hydrological status of various rivers
of India viz. Ganga, Ravi was evaluated for their water
quality, hydrological and fisherles status. In river Ravi
the main anthropogenic activity affecting Its ecology is
water abstraction and agricuhval pollution. The inmion
of Clarias garieptnus within Yamuna, Sutlej and Bea
is a cause of concern.
In river Ganga on the basis of the rate of energy
transformation by producers the river can be divided
into three zones with upper zone having minimum
value (529 Cal m"day I) and maximum in the middle
zone (4942 Cal m.'day I). On the basis of fish production
potentla1 and potential energy resource also, the Ganga
can be divided into three zones, with upper zone
showing minimum value (18.3 Kg ha 'yrl and 21,991
Kg ha Iyr I) and middle zone showing the maximum
(167.6 Kg ha 'yr ' and 2,01,185 Kg ha-'yr '1.
In river Ganga, the fishery has shown a sharp decline
as compared to 1960s. At Alkhabad the yield rate has
come down to 377.6 Kg km" from 935.4 Kg km" of
the past with major carp declining to one fifth of the
past. The major carp contribution was very low In the
lower stretch except Farakka where It formed 14.1% of
the total. Exotic carps, mainly Cyprinus wpio, were
observed only in the middle stretch and its contribution
was 25.5% of the total fish landing at Allahabad and
19.4% at Varanasi. Tdapia sp. were also observed, but
only at Allahabad.
The socio-economic survey of fishermen community
rewaled decline In fiing in the river that has r edd
in shtfting of a good number of fishers towards other
occupation.

Reservoir Fisheries
Investigations on the reservoirs of Karnataka. Uttar
Pradesh, Himachal Pradesh and Rajasthan were
conducted for developing optimum management norm
for fish enhancement.
An estimated fish catch of 9881 Kg recorded at Kabini
reservoir in the month of April 2006 was the highest
during the period. Oreochrornjs mossarnbicus (33.1%)
daninated the catch fdbwed by CLprinllr carpi0 (27.8'h),
Lsko &fa (12.3%1), Ompok bimaculatus (12.3%).
Cladas gariepinus (4.7%) and others (9.7%)) which
included Notopterus notopten~s, Mystus cavasjus.

was detdned up to 25.8 km from the c&ne during
winter. It was effectively marked up to 22.2 km from
the seashore during summer, but further extended up
to a total 50.2 km during monsoon when the river
dlrharge was maximal. Identally, the estuarine mixing
zone represented the most productive zone where the
fishing activity was consistently at a peak in winter
contributing about 92 -96 O/o of the total estuarine
production.
Wmter Migratory Bagnet Fish (WMBFJ in kwer estuary

Survey for fish species diversity in the two wetlands
from Khagaria district of Biar, Kasaraiya (40ha) which
is in Gandak basin and Lakhmania (30ha) which is in
Kosi river basin recorded 33 species belonging to 22
genera and 16 families from Kasaraiya wetland and 18
species belonging to 10 genera and 9 families from
Lakhmania wetland. Gross primary production (GPP,
mgCm 3h I) in Lakhmania was comparatively higher
(62.50 "2.09) than Kasaraiya (52.09 '14.59).
The germplasm survey was carried in Chandania
(seasonally open) and Chamordaha (closed) wetlands in
24 Parganas (North) diict of West Bengal. Fish species
diwrsity was found to be higher in Chandania (.% species)
belonging to 24 genera and 17 families. In Chamordaha
21 species were recorded under 15 genera and 10

The socio-economic issues of the fishers of Bihar and
West Bengal studied indicated that in Bihar the main
occupation of the fishers was fisheries. while daily labour
in agriculture was the secondary source of livelihood
Nearly 54% of fishers are having their own crafts, and
64% Imving their own gear. The average annual fishing
effort was 268 days with average catch of 1.63 Kg day

Fish landing data from Uzanbarar fish assembly centre
of River Brahmaputra was collected following systematic
sampling design A total of 236.5 t of fishes was estimated
to have been landed during the year as compared to
225.4 t during the previous year, showing 4.3% increase
in the overall catch. Miscellaneous species dominated
the catch followed by major carps, minor carps, Hilsa.
catfishes and feather-backs. The highest landings was
recorded during post monsoon season.
Fish health & Environment
Rigorous pesticide risk assessment studies indicated
presence of DDT, HCH and their metabolites in all the
sampling stations of river and wetlands. Organochlorene
pesticide, 4,4'-DDT, was present in concentrations higha
than its permissible limits in water for aquatic life.
Application of Health Assessment Index (HAI) in fish of

Brief History
Based on the recommendations of Sub-committee of
the Central Government on Agriculture, Forestry and
Fisheries, the Central Wand Fishaies Research Station
was formaliy e staW on 17th March 1947 at Calcutta
under the Ministry of Food and Agricutture, Gowmment
of India. From this modest beginning, the station
expanded its activities and was elevated in 1959 to the
status of an Institute (CIFRI) and moved to its own
building at Barrackpore. West Bengal. &er the years,
the organization has grown and established itself as a
premier research institution in the field of the inland
fisheries and aquatic ecology in the country. Since 1%7.
the lnstitute is under the adrninistmtive control of Indian
Council of Agricultural Research (ICAR), DARE, and
Govt. of India.
Initmlly the main objectiw of this lnstitute was to conduct
investigations for a proper appraisal of all inland fishery
resources of the country and to evolve suitable methods
for their optimum fish production. While fulfilling the
above objective, the lnstitute directed its research efforts
towards understanding the ecology and production
functions of different types of inland water bodies in the
country. But investigation were also conducted to
lodastandpondecogrstgn,itsbeatirgmfishproduction
which eventually lead to develqment of farming p radi
to obtain high fish yield from unit of water area.
The lnstitute during late sixties and seventies focussed
its attention on aquaculture research and development
in consonance with the plan priorities of Government
of India. Having achieved significant progress in hshen/
research and farming practices in the country, the
planners between 1971-1973 approved All-India
Coordinated Research Projects on "Composite Fish
Culture'. "RiclerineFishSeed-,
"A&breath&lg
Fish Culture", "Ecology and Rsheries Management of
Reservoirs" and 'Braddsh water Fish Farming". The
succgsof~proigtof'CanpositeFkhC~
& Fish Seed Production" initiated in 1974 was the
turning point in the history of fish culture in India and
provided a solid foundation for the development of
freshwater aquaculture in the country. This resulted In
the e s t a m t of the Freshwater Aqudtw Resemh
& Training Centre at Dhauli (Orissa) in 1977, which
later became, Central Institute of Freshwater Aquaculture
(CIFA) in 1987. Simultaneously, Central Institute of
Brad&hwater Aquaculture (CIBA) and Natii Researrh
Centre on Coldwater Fisheries ( N R O were carved
out from this Institute to carry out research on braddshwater
aquaculture and coldwater fisheries respectlvely.
Thus. ClFRl gave birth to three major fisheries research
institutions in the country.
As a consequence of creating speclallsed wctoral institutes
and keeping in view the emerging issues in open-water
fishery science within and outside the country, wlth
greater emphasis on open water fisheries and aquatic
resource management, the CIFRl mandate, was modified.
Mandate
In order to cater to the needs of the changing scenario,
the research and developmental programmes in lnknd
fdwq sector demands reorientation of research priorities
for achieving sustainable production besides conserving
the precious biodksity, the backbone of any production
system. It is in this backdrop that the lnstitute had to
shift its focus from :
4 'Production optimization' to 'Sustainable
Productivity'
4 'Fish as the only benefit' to 'Ecosystem Health
and kefits'
With this shift in focus, the mandate of the institute is
as under :

2. To develop ecosystem-based technology and
strategies for productivity enhancement in
mandated waters
3. To monitor environmental changes, their impacts
on fisheries arid develaping rnitigatlon action pbns
in collaboration with other organizations
4. To create awareness, provide training and
cansultancy in inland open-waters
OTganisational Structure
Till the revised divisional plan r$lelred in revised VISION-
2025 is approved by the Cow~cil, at present the Institute
is pursuing Its research activities through seven main
MvUons which are in han supported by different research
support services / sections. The Riverine Division,
with its headquarters at Allahabad, in U.P. strives to
monitor and develop effective management action plan
for riverine fisheries and resources of the country with
adequate emphasis on the conservation of fish stocks
and riverlne environment. The Reserwir Division is
based at Bangalore, in Karanataka. The investigations
carried out in the Division are aimed at developing
management norms for optimising fish yie!d from large,
medium and small reservoirs of the country. The
Barrackpore-basal Estuarine Division is invobed in

development of environment-friedy technologies. The
Resource Assessment Division is located at
Barrackpore and conducts research aiming at creating
a database on the fish stocks and fishery resources. The
Division is geared up to develop various population
models that can lead to sustainable exploitation of inland
fish stocks and develop resource management database
on GIs fmt. The Human R m Lkwbpment
and Transfer of Technology Division is located
at Barrackpore. The institute has aimed at manpower
training and education of fisheries personnel under
Human Resource Development for producing qualified
persons. The Transfer of Technology wing undertakes,
on regular basis, the dissemination of various technologies
of inland fisheries to the fish farmers, fishermen,
entrepreneurs, extension functionaries through training,
demonstration, advisory setvice, fish farmers' day, camp
discussion, film show, exhibition, etc.
The Director in Research Management Position heads
the Institute. The responsibility of overall management
of the lnstitute lies with Management Committee under
the chairmanship of the Director. The Staff Research
Council and the Research Advisory Committee make
the specific recommendations pertaining to research
and extension activities of the Institute. The Institute's
research activities are organised under various research
projects, which are executed from the headquarters at
Barrackpore (Kolkata), and Regional Centres at
Allahabad, Bangalore, Vadodara and Guwahati. The

Ecology & Fishery of river Ravi
River Ravi, one of the three eastern rivers of the lndus
basin, has been evaluated for its ecology and fishery
resources within plains of Punjab for an estimated length
of 170 km.
Abiotic chamctsrlstrcs
Water : Water temperature of river Ravi within Kandi
regions of Punjab showed less variation and ranged
between 2023°C sllghtty higher than hst yeu 20-22%.
but in lower plains the temperature varied from 17-30°C
River water was alkailne with pH ranging between 7.3.
7.6. Dissolved oxygen content ranged between 6.6 to
7.2, B.O.D. 1.0-1.2 mgv1 and C.O.D, values between
3.24.3 mg14 indicating no pdhtional load. Total alkalinity
ranges betwen 79.3 and 118.0 mgl ' indicated it to be
productive.
Gross primary production varied between 10208
and 148.960 mgC m 'hr ' being lowest at Derababa
Nanak and highest at Kathlour and net production
varied between 67.710 and 114.58 mg~m3hr'. The
production exhibited seasonal variation all along the
river, minimum during monsoon (56.25-62.50) and
maximum during post-monsoon (140.62.312.50
mgCm 'hr '). The ratio between Gross Production
and Respiration varied between 2.16 and 3.1 with
Lcmrest values at below and highest at Kathlour
indlcativa of not much pollutional load.
Biotic characteristics
Plankton : Plankton population is mainly formed of
phyto grwp contributed by diatoms (66-lm) and green
algae (0-34%). Zooplankton, in the form of Rotifers (11%)
was present only at KatNour. Population did not exhibit
any change from last year. Absence of myxophyceae
indicate clean river conducive for fishery but not for
surface feeders because of the low plankton crop.
Periphytn : Periphyton concentration within Ravi was
substantial, 222608 urn ', which is mainly due to river
bed characteristics, transparent water and low water
depth. The periphyton concentration unlike plankton
was higher in pre-monsoon (367-767 ucm ') compared
to post-monsoon (200-501 ucm ') and monsoon (134-
567 ucm '). Periphyton population like plankton was
dominated by diatoms (7046%) but also had presence
of blue green algae (14.20%). Common forms present
were &toma, Navicula among diatoms, Mkrospora,
Crucigenia, Pleuroccocus among green algae and
Oscillatoria, Microcystis among blue green algae.
Macrobenthos : The average density ranged between
277-3207 um ', minimum at Shahpur and maximum
at below barrage site. The density was high during pre
m o m (633% urn") at all stations except Kathlour.
Benthic population exhibited substrate, thermal and

Biotic characteristics
Fishery : Fkh landings at Whpur and Damgm-11 landlng
centers were estimated at 86.85 and 44.44 t. The
contribution of major carp and large sized catfishes was
about 9% each at Sadkpur. Sadiapur landings showed
an 17.0% increase as compared to the preceding year.
The maximum increase was in landings of C.rnrfga1a
(35.1%), however, catches of Catla catla declined to
50% of the preceding year. Others comprising of R.
rita. C. gama, E. vacha, Chela spp., A. morar, !
coitor, A. coila and some other smaller species also
registered an increase of 25%. Among exotics catches
of Tilapia increased sharply Landings of C. carpiowere
estimated at 22.14 t and shaved an increase of 11.8%
over landings in the year 2005. At Daraganj the landings
increased by 45.4% as compared to the landing in 2005.
Major carps catch were almost double of the preceding
year; landings of mrigal and catla showed a marked
increase. However, the large catfishes showed a decline
and landings were almost half of the preceding year.
The yield rate was computed as 377.6 kg km ', out of
which the contribution of major carps and large sized
catfishes was merely 10.2 and 10.5% respeaively. The
conbibution of others and exotics were 53.8 arid 25.5%.
As compared to 1961-68 fish catch, the fishery has
shown drastic change and decline (IMC-45.4%; large
catfishes-21.5% in a total of 935.4 kg km I) in recent
years.
At all centers the fishery was dominated by smaller
species (427100%). In the upper stretch (Rishikesh-
Haridwar) the contribution of major carps was negUgtMo
and a good fishery of Tor spp. and L. dero was
observed, specifically in the stretch below Hatidwar. In

only in the upper stretch.
Fishery from Ganga showed sharp decline as compared
to that in 1960s. At Allahabad yield came down to 381

Socioeconomic analysis of fishermen community:
Socio-economic survey of fishermen community were
carried out in 16 villages in the upper stretch (Deoprayag
to Haridwar), 12 in Bhagalpur region and 11 in the
Farakka region It was found that the meager catch
per day from the river has resulted in poor monthly
income, insufficient to meet fishers' food requirement.
Decline in fisheries of the river has resulted in
unemployment among fishers and a good proportion
has shifted to other occupations.

Hydrology and fisheries of Hooghly estuary
Lkheation of mlwing zone : A sea uyage was carried
out in three seasons v&., monsoon, winter and summer
during 2005-06 & 2006-07 on the eastern bank of
Hooghly estuarine delta with the objective of delineating
the zone of Hooghty estuarine intrusion (mixing zone)
in to the Bay of Bengal. Considering that salinity is an
ideal pammeter for the purpose, subnvface water samples
were collected and analysed on linear basis using the
GPS at known intervals of distance starting from the
coastline and proceeding fartha seawards till the salinity
was of the order of near-seawater value. Based on the
salinity and distance relationship the zone of estuarine
intrusion was determined up to 25.8 km from the
coastline during winter. It was effectively marked up to
22.2 km from the sea shore during summer. but further
extended up to a total 50.2 km during monswn when
the river d hrge was maximal. Incidentalb, the estuarine
mixing zone represented the most productive zone where
the fishing activity was consistently at a peak in winter
contributing about 92 -96 U/o of the total estuarine
production.

between 13.56-29.63 ppt and 5-32 an respectively.

while the values were between 5.8-27.1 ppt and 6.0-
98.0 an in Sagar area. A positive correlation could be
established between the abundance of prey species of
Acetes indicus and the bagnet catch comprising of 90

Plankton diversify : The plankton profile at Jharkhali
(high saline mangrove area) and lchamati (low saline
mangrove area, Hingalganj) were investigated in relation
to quantitative abundance and qualitative texture. The
phytoplankton abundance at Jharkhali ranged from
556-1025 ul", being the highest during winter and
lowest in monsoon. The Hingalganj area of lchhamati
indicated relatively low abundance of phytoplankton
(239-570 ul ') as compared to Jharkhali. During the

in the beeis studied, with more hanspmcy observed

In the deeper be& vlz. Wpur (4.87 m), Duma (6.02

240. 117 and 24 crn respecthdy indicating presence
of extended wphotic zone. Soil was predominantly
sandy, roil reaction was near neutral in most of the
wetlands barring Chamordaha, Charnta, Media and
Kds @H 6.5) due to innate soil character coupled with
more organic matter in soil. Organic carbon content
(96) was in the range of 2.81 (Akaiplr) to 5.98 (Media).
Phenomenal presence of available-P (mg/100 g soil)
In sediment was noticed in majority of the wetlands,
like Akaipur (4.15), Sindhrani (3.51, Kundipur (3.2),
Media (4.75), Chiandanla (3.7), Mathura (3.2). Saguna
(3.04, Kola (3.0) and the lowest value was found in
Chamta (0.8) due to innate soil character associated
with on going agricultural activities in the catchment.
Baning Cham& and Chamta, where total alkalinity
(22 & 47 mgl ') as well as hardness (57.5& 54
rngl I) were low, most of the beels were moderate to
highly productive. Higher chlorlde content was noticed
in Duma (168.5 rngl ') and Chandania (65 rngl ') and
the range was 14.9-26.3 rngl 'in rest of the beels.
indicating little or no local pollution. Nitrate-N was
found present in moderate to higher concentration
even during December and also the phosphate-P in
these wetlands. Nitrate-N (ppb) was found to a low of
240 and a high of 685 barring Saguna (48.1) and
Bhomra (48. I), reflecting moderate to high productive
trend in these wetlands.
Aimsly production : Primary productivity indicated
that most of the beds were moderately productive.
Higher rate of gross primary production (GPP, rngC m'
%rl) was o b s d in Media (693). Duma (563) and
Mathura (547) primarily due to M imqds bloom while
in the rest of the wetlands, the GPP was in the range
of 164 to 422.
Development of Hsh yiekl models
Enhancement measures along with various biological,
physical and chemkal feahves were bimonthly cdlected
fran13wetkncbbdevolcpafishyieldpgtictfvemodel
using multivariate regression analysis. The various
enhancement measures include stocking with bigger
sized fish seed of both IMC's and exotics, rernwal of
aquatic rnacrophytes. liming, sometimes resorting to
feedlng and even in rare case application of mahua oil
cake, in* mising of seeds either through pond culture
or pen rearing and so on. Vigorous stocking was done
wtth advanced fingetlings (8-15 an). Stocking frequency
was three times a year during premonsoon. monsoon
and winter which started from March / April with
common carp seeds except in Saguna where continuous
stocking was done for 8 to 10 months. The highest
catch (2067 kg ha') was associated with the highest
stocking (285 kg ha1).
A discernible negative influence of the intensity of
macrophytes cover on the average plankton volume was
noticeable in the wetlands studied. However, in
Chamordaha, despite the absence of manophytes. there
was low plankton volume (0.53 ml) which could be
attributed to high turbidity existing in this beel. The
presence of Microcystis aeruginosa in high quantity
(5267 - 5420 ml 100 1') in Media and Mathura could
be due to the nuhient loading from nearby city and also
absence of macrophytes in these beels. Zooplankton
outnumbered phytoplankton in all the wetlands under
study.
Biology of indigenous fish species
Mystus vittatus studied selectively feed on dipteran
larvae, annelid worms, crustaceans and oligochaetes.
Sex ratio was 1:0.58 to 14. The fecundity of the fish
ranged from 288(9.3crn and 8.339) to 37632 (10.2an
