ABSTRACf
Monthly observations of the' catches of deep-sea trawlers (> 70 GRT) at
two major landing centers i.e. Endau, Johor and Kuantan, Pahang were carried
out from February 1993 to October 1994. The catches were grouped into 9
categories namely: demersal fish, pelagic fish, mixed fish, penaeid prawns,
cephalopods, crabs, lobsters, others and trash fish . The majority of the
catches consisted of trash fish, followed by demersal fish, cephalopod, and
pelagic fish. The species composition indicated that a high diversity of
species were caught. Nemipterids (ikari kerisi) and priacanthids (ikan lolong
bara) were dominant in the catches of these trawlers. For both landing centers
the highest catches was observed in the months between July and December
while the very low catches occurred in the months between January and
June. An inverse relationship was observed in the catches of cephalopods
where during lower catches ofLoligo spp.(squid), there were higher catches
of Sepia spp. (cuttlefish). The total catch by deep sea trawlers based in
Kuantan, Pahang was higher than those in Endau, Johor with a ratio of 2: 1
especially for demersal fish and trash fish. This fishery still has the potential
to be developed and suggestions towards a sustainable fishery were also put
forward.

ABSTRAK
Pemerhatian bulanan bagi tangkapan bot-bot pukat tunda laut dalam (>70
GRT) iaitu di Endau, Johor dan Kuantan, Pahang telah dijalankan dari bulan
Februari 1993 hingga Oktober 1994. Hasil tangkapan telahdi bahagikan
kepada 9 kategori iaitu ikan demersal, ikan pelagik, ikan campur, udang
penaeid, ketam, udang karang, lain-lain dan ikan baja. Sebahagian besar
daripada hasil tangkapan adalah ikan baja, diikuti oleh ikan demersal, sotong
dan ikan pelagik. Komposisi species menunjukan pelbagai species telah di
tangkap. Nemipteridae (ikan kerisi) dan Priacanthidae (ikan lolong bara)
merupakan tangkapan utama bagi bot pukat tunda ini. Bagi kedua-dua pusat
pendaratan, tangkapan tertinggi adalah dari bulaJ;lJulai hingga Disember
sementara tangkapan paling rendah adalah dari bulan Januari hingga Jun.
Adalah diperhatikan apabila tangkapan sotong biasa (Loligo spp.) rendah
tangkapan sotong katak (Sepia spp.) adalah tinggi. Secara perbandingan
tangkapan· bot-bot pukat tunda laut dalam yang berpengkalan di Kuantan,
Pahang adalah lebih tinggi daripada tangkapan bot-bot yang berpengkalan di
Endau, Johor pada nisbah 2:1terutamanya bagi ikan demersal dan ikan baja.
Perikanan ini jelas masih berpotensi untuk di majukan dan cadangan juga
telah di beri agar perikanan ini terus berkembang.

With the declaration of the 200 nautical miles Exclusive Economic
Zone (EEZ) under the UN Convention of the Law ofthe Sea (UNCLOS),
Coastal States have increased responsibility in the management and
exploitation of marine resources within the areas. In Malaysia, the
Department of Fisheries has been given the responsibility to manage
the fisheries resources in the EEZ waters for exploitation by Malaysian
fishermen at the maximum sustainable yield (MSY) level. Since the
early 70's resource surveys were conducted in the South China Sea
inclusive of area off the 'east coast of Peninsular Malaysia, using RJV
CHA~GI in 1970, Dr. Fridjorn Nensen (Aglen et al., 1981), R.Y.
Kagoshima Maru (Mohsin et al., 1985) and Kagoshima Maru (Mohsin et
al., 1986). Besides, there were also surveys carried out by the Department
of Fisheries in the coastal waters of the east coast (Jothy et al., 1975,
Lam et al., 1975, and Lamp and Mohd. Shaari, 1976). Despite the
encouraging results and resources potential, the deep-sea fishery on the
east coast of Peninsular Malaysia was only developed after the mid
80's.
In order to develop and encourage the deep-sea fishing in Malaysia, the
Department of Fisheries had conducted a comprehensive survey in the
Malaysian EEZ waters in 1986. Results obtained were very encouraging.
Potential yield of demersal fish for the east coast of Peninsular Malaysia
was estimated at 82,200 tonnes (Anon, 1987). Considering this result,
the Department of Fisheries was prepared to issue 196 deep-sea fishing
boat licenses for the east coast of Peninsular Malaysia. Trawlers of 70
GRT and above were classified as the deep-sea trawlers. These tYpes of
boats were categorised as Zone C 2 trawlers and only allowed to do
fishing in the area of more than 30 nautical miles from the coast.
Since the implementation of deep-sea fishing in 1987 on the east coast
of Peninsular Malaysia, the status of this fishery has not been assessed.
However, the annual landings of the deep-sea trawlers have been recorded
in the annual fisheries statistics. Shaupi & Lim (1995) have described
the performance of deep-sea fisheries for the year of 1993. They pointed
out a decline in the profit of deep-sea trawlers in Johor and Pahang from

6.5 % and 19.5 % in 1991 to 0.2 % and 12.1 % in 1993, respectively.
This preliminary paper aims to highlight the deep-sea trawlers landings
monitored at two major centers, Le., Endau, Johor and Kuantan, Pahang.
It gives an overall picture on performance of these trawlers in terms of
the catch per unit effort (CPUE), catch composition and total catch.
2.1 Annual Landing Data
Annual landing data of the 70 GRT and above trawlers from the year
1980 to 1993 on the east coast of Peninsular Malaysia were extracted
from the annual fisheries statistics. The data were then analyzed using
the Schaefer's Production Model.
2.2 Monthly Landing Data
Monthly landing data from deep-sea trawlers were collected at the
selected landing centers from February 1993 to October 1994. Data
collection was based on "random sampling" and "direct recording"
method. The number of boats sampled every month was between 3 to 5.
The fishes were identified possibly up to species level. Information
regarding the fishing operation such as numbers 'of fishing days, area
and number of hauls were recorded through verbal interview with the
skipper (taikong) of the sampled boat. The total catches of trash fish
were first recorded before a sub-sample was taken to verify the species
composition.
i
For comparison purposes, catches from sampled boats were converted
into standardized CPUE. This was done by dividing total catch with the
number of fishing days then multiplying by 7, the minimum fishing days
accepted for these categories of boat. Data of the! respective months
were grouped into 9 categories, Le., demersal fish, pelagic fish, mixed
fish, penaeid prawns, cephalopods, crabs, lobsters, others and trash fish.

2.3 Fishing Operations
The boats usually operated about 7 to 9 days per trip and with an average
of 8 days per trip. In one month there would be 2 to 3 trips averaging
about 2.3 trips. The size of crew working in a trawler varied between
four and five persons. The fishing boats were wooden stern trawlers
equipped with wooden booms and the towing warp was made of
polypropylene. The towing speed was between 4 and 5 mots. The average
duration per haul was 3 hours. Three hauls were usually operated daily
during the day time.
The trawl nets used were 2 seam type nets with its head rope ranging
between 35 and 55 meters and size of the cod-end about 38 millimeter.
The net drum was used to assist during shooting and hauling operations.
The Global Positioning System (GPS) was used to locate the position
of fishing grounds. For communication purposes most of the boats were
equipped with mobile phones.
3.1 Annual Landing Trend
A total of 150~licences for deep-sea trawlers had been issued by the
Department of Fisheries in the east coast of Peninsular Malaysia from
1987 to 1993. During this period, deep-sea trawlers had yielded about
252,395 tonnes of which 126,452 tonnes were commercial fish. The
annual landing of trawlers before the i~troduction of deep-sea trawlers,
was only about 30,000 tonnes. In 1988 the annual landing of trawlers
increased by more than 70 % to about 127,000 tonnes (Table 2). The
landings of deep-sea trawlers had drastically increased with the increase
in numbers of fishing units in operation since 1987 (Table 1). Landings
however decreased in 1989 before picking up again and reaching peak in
1992 (Figure 1). This trend shows that the EEZ in the South China Sea
area has resource potential and the trawl fishery has become evermore
important.

The commercial fish in the overall landings by deep-sea trawlers varied
between 43.9 % in 1992 to 84.9 % in 1988. In 1993 commercial fish
was recorded at 20,000 tonnes (Table 1, Figure 1). The major fishes of
the commercial fish group were demersal fish, Le., kerisi (Nemipteridae),
pulutan (Ariidae), kerisi bali (Pristipomoides spp) , biji nangka
(Mullidae), merah (Lutjanus malabaricus) and rays. Apparently these
major fish groups have determined the pattern of commercial landing of
these trawlers. Between 1988 and 1993 these fishes contributed about
22 % of the total landings of deep-sea trawlers.
3.2 Catch Rate and Season
Forboth landing centers the highest catches were observed in the months
between July to December while low catches occurred in the months
between January to June (Figures 2 & 3). The higher catches during the
peak season were due to the increase in trash fish catches. During this
season, the catches varied from 12,000 kg to 16,000 kg and 5,000 kg to
11,000 kg in Kuantan and Endau, respectively. Whilst in the low-catch
season, these varied from .1,000 kg to 13,000 kg and 3,000 kg to 6,000
kg in Kuantan and Endau, respectively. Catches of trash fish were
observed to increase in July, reaching a peak between September and
October. During the peak season the catches of trash fish were between
6,000 - 11,000 kg and 3,000 - 8,000 kg in Kuantan and Endau,
respectively (Table 3 to Table 6). Fish recruitment is attributed as the
main reason for the higher catches of trash fish during this period.
Recruitment begins in June for species such as Nemipterus peronii
(Kimoto and Ibrahim, 1996) and most of the small pelagics (Mans or
and Syed Abdullah, 1996). The increasing trend in the trash fish catches
was probably due to the increase in size and body weight of the young
fish.
The demersal fish group contributed more than 18 % of the total catches
of these trawlers (Table 3 to Table 6). The catch trend of demersal fish
seem to correspond trash fish catches. The higher catches occurred
from August to December with catches between 3,000 - 5,000 kg and
900 - 2,500 kg and the lower catches were from January to July with
catches of between 1,500 - 3,000 kg and 300 - 2,000 kg in Kuantan and

Endau, respectively (Figure 4). As for the pelagic fish the catches are
higher from October to February with catches between 900 - 1,800 kg
and 500 - 1000 kg in Kuantan and Endau, respectively (Figure 5). The
low activity of the purse seiners due to the rough sea conditions was
believed to be the main factor that contributed to the high catches of
pelagic fish by these trawlers during this period.
The second important group were the cephalopods. This group which
contributed from 8 % to 14 % of the total catches of the trawlers
consisted of Loligo spp. and Sepia spp (Table 3 to Table 6). The higher
catches of Loligo spp. were from February to July with catches between
400 kg - 1500 kg and 400 kg - 1300 kg and the lower catch rate from
August to January with catches between 100 kg - 600 kg and 180 kg -
450 kg in Kll;antan and Endau, respectively (Figure 6). An inverse
relationship was observed in the catches of cephalopods. During low
catches of foligo spp. there would be a high catch of Sepia spp. (Figure
7). This phenomenon had enabled fishermen to have a continuous catch
of cephalopods.
It was found that the total catches of deep-sea trawlers based in Kuantan,
Pahang were higher \han in Endau, Johor at a ratio of 2: 1, especially for
demersal fish and trash fish. Mohd Shaupi and Lim (1995) reported that
the turnover of this category of boats based in East Johor declined from
6.5 % (1991) to 0.2 % (1993) due to the high competition between
these boats and also those of less than 70 GRT boats fishing in the same
area. This enigma should be further studied but it was believed that it
was due to various factors including the location of port and differences
of fishing grounds. Deep-sea trawlers based in Kuantan, Pahang have a
wider area to fish. They could easily go out fishing either on the southern
part, middle part or northern part of the EEZ waters. Conversely, the
Endau trawlers could only fish in the southern part and middle part of
the EEZ waters. For Enciau fishermen to fish in the northern part of the
EEZ waters it would incur higher cost due to unfamiliar fishing grounds
and great distance from home. The second factor would be due to lack
of fishing expertise. More than 30 % of the skippers of the deep-sea
trawlers based in Kuantan were Thais who had more fishing experiences
than the local skippers in Endau. The third factor would be related to the

decline of demersal resources in the middle part and southern part of
EEZ waters. A Survey conducted by Department of Fisheries in 1986
showed that the northern part of EEZ waters consisted of higher stock
of demersal fish especially off Terengganu waters than other part of the
EEZ waters.
3.3 Catch Composition
Analysis of the species composition of the catches indicated that a high
diversity of species were caught by these trawlers. The major species of
demersal fish were kerisi (Nemipterus furcosus, N. tambuloides, N.
sp.2, N. nemurus, and N. nematophorus), lolong bara (Priacanthus
tayenus and P macracanthus ), conor (Saurida spp.), merah (Lutjanus
malabaricus), pulutan (Arius thalassinus), kerisi bali (Pristipomoides
typus) and timah (Trichiurus spp) (Table 3 - 6). The composition was
nearly similar to the results obtained from the studies conducted by
Aglen et al.(1981) and Department of Fisheries (1987). The major
species of pelagic fish were selayang (Decapterus russe//i), selar kuning
(Selaroides leptolepis), selar (Selar crumenophthalmus). In
cephalopods, the major components were squids consisting of Lo/igo
duvauce//i, L. chinensis and L. edulis and for cuttlefish the major
species were mainly Sepia recurvirostra, S. esculenta and Sepie//a
inermis. Mixed fish consisted of demersal and pelagic species and
usually the catches were in a small quantities.
The current status of potential yield in the deep-sea areas on the east
II coast of Peninsular Malaysia is still being monitored. From previous
I:, works, the demersal resource of the coastal areas was estimated at around
80,000 to 153,000 tonnes. For instance, Mohd Shaari (1976) gave a
figure of about 153,325 tonnes of catchable fish; Pathansali (1976)
about 95,000 to 130,000 tonnes; while for the deep-sea area, Aglen et
al. (1981) provided estimates of around 100,000 tonnes. The Department
of Fisheries Malaysia conducted a trawl survey in 1987 for the whole
EEZ areas of more than 25 nautical miles offshore and provided
estimates of about 82,200 tonnes of catchable fish comprising 55,100
tonnes of food fish and 27,100 tonnes trash fish (Anon, 1987).

The seasonal and annual fluctuations (Mohd. Shaari, 1976; Pathansali,
1.976) in the fish population on the east coast of Peninsular Malaysia
form the main difficulty when estimating the actual potential yield.
Applying Schaefer's model on the annual landing data gave an estimated
MSY of 31,400 tonnes of commercial fish while the highest landing
record of commercial fish was only 26,347 tonnes in 1991 (Figure 8).
It seemed that only half of the total food fish (55,100 tonnes) estimated
by Department of Fisheries was exploited by deep-sea trawlers. Temporal
variation in fish population and exploitation by other gears were believed
to be the main reasons for the different figures. A Survey by the
Department of Fisheries in 1986 was conducted during the peak season
of demersal resources, i.e., between October and November 1986 and
this led to an over estimation of demersal resources. Mohd. Shaari
(1976) noted the monthly and annual variation of the estimated catchable
fish resources on the east coast of Peninsular Malaysia.
The large area of unexploited EEZ waters was then inevitably exposed
to foreign encroachment. The amounts of fish caught by the foreign
vessels could not be estimated. Some trawlers that are less than 70 GRT
including those vessels using hooks and lines are able to fish beyond 30
nautical miles limits. Landings from these categories of gear were
impossible to categorise into coastal fishing and deep-sea fishing. But
it was believed at least about a quarter of the total fish landed by those
gears were caught from deep-sea area. The deep-sea waters of the South
China Sea area is still found to have the potential to be developed and
the commercial demersal resources are estimated to be between 30,000
tonnes and 45,000 tonnes. The potential yields for the months of January
to June is about 30,000 tonnes and between August and December is
about 45,000 tonnes.
3.5 Trash Fish Composition
At the initial stage of deep-sea fishing activities in 1987, the landings
contributed to about IS % to 35 % of total trash fish. However, since
1989 the percentage of trash fish composition has increased (Table I).
This is a common phenomenon for all exploited fish stocks where the
fishery is producing a relatively constant yield but the underlying species

composItIOn consisted of smaller, younger fish and generally of less
value (Mahyam, 1992). A survey conducted by'Department of Fisheries
in 1986 recorded that the average percentage of trash fish was 32.9 %
and the undersized commercial fish was about 40 % of the total trash.
This study found that the percentage of trash fish rose to 58 % in the
catches (Table 3 to Table 6) and the undersized commercial fish increased
to 70 % in the total trash (Table 7 to Table 10). The major species of
undersized commercial fish were kerisi (Nemipterus spp.), lolong bara
(Priacanthus spp.), conor (Saurida spp.), biji nangka (Upeneus spp.),
selayang (Decapterus spp.) and selar kuning (Selaroides leptolepis ).
The genuine trash fish were buntal (Tetraodontidae), kekek
(Leiognathidae), barat-barat (Monocanthidae), and sebekah
(Apogonidae). The higher percentage of Nemipterus spp., Priacanthus
spp., Upeneus spp. and Leiognathidae showed that these trawlers fished
in shallower waters, i.e., (18 to 55 m depth) as the results are similar to
those obtained by Department of Fisheries in 1986. These trawlers were
believed to operate in area just outside the 30 nautical mile limits and
occasionally cross inwards towards the shore particularly during
monsoon and squids seasons.
Higher catches of trash fish and the higher percentage of undersized
commercial fish indicated that the population structure of the demersal
resources in the deep-sea waters consisted mainly of smaller fish. The
.increasing trend of trash fish landed is alarming in recent years
. silggesting intense exploitation. The lowering of age at first capture
"'could bring disaster on the fish stock (Kimoto and Ibrahim, 1996).
Mahyam, (1992) reported that deep sea trawlers based at Hutan
Melintang, Perak landed 40-70 % of total catch as trash and
recomendations were made to overcome this trash fish problem. This
paper proposes some additional suggestions:
a) Protect the EEZ waters from foreign encroachment since it was
believed that the intense exploitation of the demersal stock was the
result of excessive pressure by uncontrolled foreign fishing boat.

) Spawning and nursery grounds in the fishing ground areas should be
protected by regulation emphasizing responsible fishing and
c) Deploy more artificial reefs or permanently sub-merged FAD which
serves as sanctuaries for juvenile fish to grow.
Precise knowledge related to species composition, distribution, density,
population structure, and seasonal fluctuation of commercial species
are important in projecting the future prospects of this fishery. A second
trawl survey for the whole EEZ waters of the east coast seems necessary
to assess the potential and the latest status of the demersal resources.
From this paper it is suggested that the status of the deep-sea stock has
been fully exploited at the level of fishing effort. It is apparent that the
deep-sea trawlers tend to fish just outside the 30 nautical mile limits.
Further expansion of the deep-sea fishing could be encouraged through
the following steps:
a) Kuantan fishing port should be developed into a larger fishing port
on the east coast of Peninsular Malaysia and should become a major
base for deep-sea fishing activities. The number of deep-sea trawlers
licensed should also take into account the numbers of fishing boats
of less than 70 GRT capable of fishing in deeper waters especially
Zone C trawlers.
b) Skippers of deep-sea fishing boats should have navigational
qualifications and be certified and trained by authorized body.
c) All deep-sea fishing boats should be permitted to fish, regardless
of state limits. This would eventually stabilize and equalize the
fishing pressure on the stock.
d) Lack of workers in this fishery has been obvious in recent years and
the temporary solution was the intake of foreign workers. For the
long term planning it is suggested that the cod-end mesh size be

increased to catch only the commercial sized fish. This measure
could reduce the· crew needed in sorting the catche~. Moreover by
raising the age at first capture the depletion of fish stock can be
avoided (Kimoto and Ibrahim 1996).
e) Suggestions to the use of the 6-seam net and board-kite otter-board
to reduce operation cost and increase fishing efficiency (Rosidi
and Ibrahim, 1992) should be considered.
