Abstract

The pond aquaculture sector in Bangladesh expands rapidly. Total fish production from pond aquaculture increasing day by day. Bangladesh ranks fifth in aquaculture production and becomes fourth in the tilapia production in the world. Total fish production in Bangladesh was about 4.27 million MT in 2017-18 fiscal years and the pond aquaculture production was about 1.9 million MT which contributes about 44.43% of the total fisheries production in 2017-18. That means pond aquaculture contributes a lot in Bangladesh fisheries sectors. For getting proper outcome from the pond aquaculture some basic guidelines should be followed during pre-stocking, stocking, and post stocking management of freshwater pond. Firstly, pond should be prepared properly before stocking of fish seed like aquatic weeds and predators should be eradicated with properly constructed the pond bottom and dike and then liming and fertilization should be done for making a better culture environment for fish. Good quality fish seed should be sock to the pond and feeding should be done properly. Periodic sampling for examining the proper growth and any disease infestation occurs should be done. Liming and fertilization should be done after stocking of fish seed if needed. Harvesting and marketing of fish should be done by considering some factors to get good profit.

Highlights

Bangladesh is riverine and located in South Asia between 20°34' to 26°38' N latitude and 88°01' to 92°42' E longitude with an area of 147570 sq. km (Sunny et al, 2020a)
Inland open water and inland closed water covers approximately 3.92 and .79 million ha respectively but the total fisheries production was 1.2 and 2.4 million metric tons (MT) respectively which indicates inland open water body is about 4.9 times more than the inland closed water body but the total culture fisheries production is double than the inland capture fisheries production (DoF, 2018)
In 1983-84, inland capture and culture fisheries shared to the total fish production about 62.59 and 15.53 percent, respectively; whereas in 2017-18, inland capture and culture www.cribfb.com/journal/index.php/BJMSR Bangladesh Journal of Multidisciplinary Scientific Research Vol 2, No 2; 2020 fisheries share to the total fish production were 28.45 and 56.24 percent, respectively (DoF, 2018)

Summary

Introduction

Bangladesh is riverine and located in South Asia between 20°34' to 26°38' N latitude and 88°01' to 92°42' E longitude with an area of 147570 sq. km (Sunny et al, 2020a). Inland open water captures fisheries production Bangladesh ranks third and fifth in aquaculture production in the world (Sunny et al, 2020b). Bangladesh ranks 4th in the world in tilapia production and 3rd in Asia (DoF, 2018). In 1983-84, inland capture and culture fisheries shared to the total fish production about 62.59 and 15.53 percent, respectively; whereas in 2017-18, inland capture and culture. The total inland fisheries production from both capture and culture is about 3621954 MT on which pond aquaculture itself contributes about 1900298 MT which is about 44.43% of the total fisheries production in 2017–2018 of Bangladesh (DoF, 2018). Among different sectors of inland culture fisheries production, pond aquaculture contributes several folds more than the other sectors. The shrimp aquaculture contributes about 254367 MT and the seasonal culture contributes about 216353 MT in inland culture fisheries production and the contribution of other cultural sectors are so negligible (Figure 2)
