V. Bioresource Profile ..,,;, Table 2 Timber bio-resource of the Pulicat Lake
Bio-resources of the region could be broadly
classified into wild and domesticated. The wild
bio-resources constitute food, feed, fodder,
ftrewood, timber, medicine, ornamentals etc:
domesticated resources include crops, livestock,
aquaculture, plantation etc.
i. Wild bio-resources
a. Terrestial- Timber, ornamentals and medicinal
plants: Among the different wild bio-resources
12 species of ornamental plants (Table 1) were
identified.

27 species of timber trees (Table 2) were also
identified as used by the local communities for
construction of houses, boats, instruments, etc.
As part of their culture even today many
traditional medicines are prepared out of leaves,
barks, seeds, roots etc, of different wild plant
species for different ailments. There are about 39
plant species (Table 3), which are identified for
such uses. However wild aquatic bio-resources is
the central point of livelihood in this system in
which fishes and prawns form a major economic
resource. Salt making and clam shells supplement
the income of the local community.
b. Aquatic Wild Bioresources:
• Fishes: Among the 88 species of fish occurring
in the lake most of them are marine and very
few of them are fresh water fishes. The fresh
water fishes constitute Perciformes,
Clupeiformes, Mugiliformes, Atheriniformes and
Tetraodontiformes species. However only eight

species (Nematalosa nasus, Hyporhamphus
libatus, Cerres limbatus, Thryssa purva,
Mugil cephalus, Silago sihama, Oxyurichthys
microlepis and Triacanthus biaculeatus) are
found in abundance. The local fisher folk
identify the following as economically valued
species mullets, lates (Koduva) Lactarias
(sudumbu) Polynemus (kala), Sillago (kilangan)
Chanos, megalops, elops etc.
The pre monsoon months were the most productive
followed by summer, post monsoon and monsoon.
Gross primary production of lake ranged from 312
to 2500 mg C/m'/day.Annual production of the lake
was computed as 312 g C/m'/year (Kaliyamurthy,
1978). The average annual fish yield of the lake is
1214tones or 34.59 kglha (Anon, Annual reports of
CIFRI, Barrackpore, 1969-1972), which is
equivalent to 3.459 kg Clba (Kaliyamurthy, 1975)
Zoo plankton .production of the southern sector of
the lake was 1.4 to 2 times higher than that of the
northern sector, which was also reflected in the
