- 1. Trends analysis of commercial Fish production in Mannar basin of Sri Lanka Nalinda Ambagamuwa (128529) Department of Aquaculture & Fisheries Faculty of Livestock Fisheries & Nutrition Wayamba University of Sri Lanka
- 2. Introduction Mannar basin is rich with numerous types of Fish resources and other commercially important resources It is directly involved with the Fish industry in Sri Lanka Mannar basin consists with seven major fishery districts Galle, Kaluthara, Colombo, Negombo, Chillaw, Puttalam and Mannar N
- 3. Rationale • There are no much findings to determine the current fish production trends of the Mannar basin • There is no much research findings to make efficient policy decision to conserve the fishery resources in Mannar basin
- 4. Major problems • Civil war condition ( Mainly in Mannar district) • Natural disasters (Tsunami, storms, cyclones) • Illegal fishing activities- Indian poaching • Sand mining • Coral mining • Hydrocarbon exploration activities
- 5. Objectives • To find out the basic trends of the fishery • To describe the present situation of the fishery in the Mannar basin • To identify the general problems in the selected fishing communities • To evaluate the socio-economic situation of the selected fishery districts
- 6. Methodology • Study area- Seven fishery districts in the Mannar basin • Project period- 15 weeks • Data collection Fish production data Annual Marine production data (Year 1981-2015) Commercial group-wise data (Year 2003-2015) Fishing fleet data Fisheries sector’s socio-economic data N
- 7. Data were collected from; Ministry of Fisheries and Aquatic Resource Development District fisheries offices The Department of Census & Statistics of Sri Lanka National Aquatic Resources Research & development Agency (NARA Year books)
- 8. Two basic test • Sequential Mann Kendal test Main turning points in the fish production(1981-2015) • Simple linear regression test Commercial Fish groups trends(2003-2015) Marine annual fish production trends(1981-2015) • SWOT analysis was conducted – with the aid of key informant persons Analysis Method

- 37. Discussion • Study reveals the main trends for the marine annual production since 1981 to 2015 and trends of commercial fish groups since 2003 to 2015 • After the tsunami devastation, trend of the annual production of Mannar basin is taking a positive state until the year 2015 • Mannar basin is highly rich and diverse with natural resources • Negombo and Kaluthara fishery districts are the high productive ones • Natural disasters are directly impact on the production of the Mannar basin
- 38. Conclusion • Negombo fishery district is the highest contributor to the Fish production of the Mannar basin among all the other districts. • Colombo fishery district is the least contributor to the Fish production of the Mannar basin • Except for Mannar district, all the other districts were showed significant upward trends for the marine annual production • Except for Kaluthara and Colombo fishery districts, all other fishery districts showed positive trends for certain commercial Fish groups
- 39. SWOT analysis results Strengths Contributes significantly to the Fish production Well facilitated harbors in districts of Mannar basin Availability of valuable Fish resources Government hand to increase Multiday boats in fishing after the tsunami devastation Weaknesses Developed industries are provisioned in western province By catch and black Fish landings Highest post harvest losses Poor enforcement of rules & regulations Lack of infrastructure for large scale fishing
- 40. Opportunities Vast tuna fishery potential, as there is a potential for large pelagic fishes Fish based eco-tourisms Tax relieve for fishery exports Threats Oil spills and waste disposal Illegal fishing Destructive fishing methods & over exploitation Coral & sand mining Climate changes
