ABSTRACT

Shrimp is one of the export items in Bangladesh. The total production of shrimp and prawn has been raised from 1.60 lakh MT in 2002-03 to 2.54 lakh MT in 2017-18. Day by day, the production and promotion of shrimp aquaculture practices have increased by developing numerous programs and projects. This study was conducted on three shrimp culture practices system of Traditional, Improved traditional and Semi-intensive farming system in Paikgacha, Khulna District. Data were randomly collected from fish farmers of each culture practices through personal interviews. The culture period was typically four months from March to July for Penaeusmonodon (local name-Bagda). The optimal range of the physio-chemical parameters (Temperature, Dissolved oxygen, Biological Oxygen Demand, Salinity, Alkalinity, and Transparency) required to monitoring the health and increasing growth of shrimps. The average production from traditional shrimp farm, improved traditional and semi-intensive farm were approximately 100-150, 100-500 and 500 to 4000 kg/ha/yr. Based on the experiment as well as we found that the Semi-intensive shrimp cultural practice is more effective and it had proved that the physio-chemical conditions of Semi-intensive shrimp farming are comparatively standard than traditional and Improved traditional farming system.

Key words: Shrimp aquaculture practices, physiochemical parameters, impacts, management approaches
