The present study was carried out in Allaipiddy for a period of eight months from June 2014 to January 2015. The socio-economic data of randomly selected 53 fishermen was obtained through pre-tested structured questionnaire, in-depth guided interview and observation. Descriptive analysis of the direct social demography was done by using SPSS. All fishermen are Catholics and Sri Lankan Tamils. The sex demography of the community explicit that male is higher in percentage (54.4 %). In the fisherfolk, families with five members are higher in percentage (33 %) and most of them are nuclear families (95 %). Majority of the active fishermen fall in the 36 -45 age-group. All the fishermen are having primary education and only 21 % of them are teetotalers. The existing fishing methods are underwater-Sirahuvalai (46 %), Seer-net fishing (21 %), Driftnet fishing (13 %), Crab-net fishing (11 %) and Arakodiyan-net fishing (9 %). Majority of fishers (90 %) are earning Rs. 20,000 to Rs. 40,000 per month, while 6 % of them earn as high as Rs. 40,000 to Rs. 60, 000. The economic analysis of the Allaipiddy fisherfolk reveals that high income earning fishermen are involved in underwater-Sirahuvalai.

Jaffna lagoon (9° 50' N and 79° 50' E to 9°20' N and 80° 30' E) is the largest lagoon in Sri Lanka and it provides many services including fishing opportunities to the people in northern Sri Lanka. However, the status of the Jaffna lagoon fishery is not fully known at present due to the lack of detailed studies over the last 40 years. Therefore, this study was designed to fulfil this research gap. Both primary data and secondary data were used in this study. Primary data, including catch and fishing effort were collected at three major landing sites, Gurunagar, Paasaiyoor, and Kachchai by making fortnight field visits from March to December 2019. Secondary data of the monthly total catch and fishing effort were obtained from the district fisheries offices in Jaffna and Kilinochchi districts in order to estimate MSY and FMSY. This study revealed that ~5340 fishers confined to 39 landing sites were actively engaged in lagoon fishing during the study period using 12 different fishing methods. Fyke nets (71%) followed by stake nets (10%), lagoon seines, and lagoon boat seines (6%) are the widely used fishing methods in lagoon fisheries. Catch rates of major fishing gear were calculated and recorded as kg fisherman-1, day-1. Stake net (37kg ± 7) reported a significantly higher catch rate than fyke net (18kg ± 3), seine net (17kg ± 6), and crab net (16kg ± 3) (p<0.05; ANOVA). Both mechanized (59%) and non-mechanized (41%) crafts are used in the lagoon fishing practices. Forty-six commercially important finfish and shellfish species belonging to 25 families were identified in the lagoon catches of which Penaeidae made the highest percentage contribution (27%), followed by Siganidae (13%), Mugilidae (11%), Lethrinidae (10%), and Gerreidae (9%). Analysis of secondary data confirmed the increasing trend of fishing effort since 2009 but the total landings declined gradually after reporting its maximum value of 6958 Mt. in 2012. A rough estimate of maximum sustainable yield of the fishery of Jaffna lagoon was 6,694 Mt with the annual fishing effort (FMSY) of 1007 crafts. As the current fishing effort is higher than the FMSY, input control measures are recommended to utilize the lagoon fishery resources in a sustainable manner.
