Effectiveness of Fish and Shrimp Seed Stocking Strategies on Inland and Aquaculture Production in Sri Lanka

Abstract

Although there are a number of fisheries and aquaculture development programmes, the country has not yet reached the level of per capita fish consumption level of about 21 kg. To overcome this problem, Sri Lankan government has been given priority to produce fish seed as the main aquaculture development strategy. But all those seed stocking programe have not reached their expectation. This research is aimed to study how far the stocking programme effect production. Stocked amount of seed was considered as independent variable and recorded production just after stocking year was considered as dependable variable. The regression analysis was applied for the data of shrimp and fresh water fish for the duration of 2006 to 2012. The result revealed that fish seed stocking density was statistically significant on fish production variation but shrimp seed stocking did not show statistically significant impact on the shrimp production variation. The inland and aquaculture yield in metric tons (Y) was related to stocking fish seed million (S) found thatY =(- 9447.93) + 19795.41 logS. It is concluded that present shrimp seed stocking programme is ineffective. Therefore, it is recommended to re adjust the shrimp seed stocking strategy to gain more shrimp production.
