Pulicat Lake 1285 to 24768 in the fish of size range from 80 to 128 mm. (Kaliyamurthy, 1981). The post larvae and juveniles of commercially important fishes like Chanos chanos, Elops saurus, Megalops cyprinoids, Sillago sihama, Gerres spp, Mugil spp, are available at the mouth region of the lake and Hemirhamphus gaimardi and Tylosurus strongylurus. showed their occurrence throughout the lake all the year round (Rao and Kaliyamurthi, 1974). The juveniles of these two sps. occurred in different salinity and different temperature but they were abundant in the 36 to 38 ppt salinity and prefer moderately higher salinity. As H. gaimardi is known for its herbivorous habit and T.' strongylurus for its carnivorous habit (prawns, mysids, and other crustaceans) their abundance in these areas may be due to ample supply of food of these fishes. • Prawns: Penaeus indicus, P. monodon, P. semisulcatus, Metapenaeus monoceros and M.dobsoni are the common Prawns that occur in the Pulicat Lake. Tiger 'Prawn and White Prawn form the major Prawn production from the system. Out of total catch of Pulicat prawns constitute about 50 % and mullets 20 %. Generally close to the lake mouth the maximum number of Prawn larvae was seen in three peaks in July, December and April. Same time a descending order of abundance towards the interior portion of the lake with peaks in December and April observed. (Gopinathan, 1978) • Crabs: Green Lagoon crabs Scylla serrata (Forskal) and Scylla tranquebarica (Fabricius) and Indian blue-swimming crab Portunus pelagius (Linnaeus) support a fairly lucrative commercial fishery in the Pulicat Lake. Scylla serrata reaches its peak during November - Junuary. This crab is preferred than other species of crabs because of its meat quality, its large size and its ability to stay alive out of water for few days. Mesopodopsis orientalis (Tattersall) is available in tIfe Pulicat Lake and it forms one of the important food items of the fishes of the lake (Kaliamurthy 1972). Deep-sea portunid crab Podophthalmus vigil (Fabricius) is an off shore crab and its occurrence in estuary is a rare phenomenon. (Raman and Srinivasagam, 1978). • Clam: Clam fishing begins in January or February and continues until October or November. The fishing method mainly carried out by women is hand picking. The annual landings of Meretrix casta were highest in 1980 (309.7 tones) and decreased in 1981 (168.2 tones) and 1982 (85.9 tones). The dramatic decrease in 1982 is a result of the fact that the shell industry, which purchased the clamshells, shifted to Sullurpet in Nellore district in Andhra Pradesh (Thangavelu and Sanjeevaraj 1988). • Crafts: A total of 575 boats operated in Pulicat region in 1985 this has increased to 5101 in 2000 mostly belonging to Wooden make and Vallam type. The boats are ordinary country crafts called 'Nattupadagu'. The length of this plank built boat ranged from 6-8 meters with a capacity of about 2 tones. The mechanized boats are around 98 mostly belongs to Kasi Visalakshikuppam and Thiruchinankuppam villages(Fisheries census 2000). (AnnexureVI). • Gears: Varity of fishing gears are used in Pulicat region, which consists of 8185 gillnets, 43<strong>06</strong> traps and 1363 loglines, these are Table 4. Group wise annual landings from the Puticat Lake during 1965-66to 1972.

commonly used by local fisher folk. Apart from this 149 Trawlnet, 12 shore seine and 22614 other types of gears are used (Fisheries census 2000) (Annexure VII). Estimation of fish landings through fish catch with different nets has been one of the quantification methods used by the Government organizations Pulicat Lake like Fisheries Departments and researchers. Such quantification helps in estimating the productivity of the lagoon systems. The data based on such estimation shows steady increase of the fish production in the system from 1950 to 1970 (Table 4&6). Also the latest data of 2000 also shows similar trend (Table 5). This increase is due to Table 5.
