摘要

Aquaculture sector is growing at amazing pace to provide nutrient rich food to the fast growing population of the developing world. Our present study encompasses aquaculture enterprises developed by female aquaculture entrepreneurs are often found in the Ganjam districts of Odisha. Out of 22 revenue blocks investigated initially with respect to large scale fish production six blocks are found to be maximally involved in aquaculture enterprises. Out of this two pond types as semi-intensive and intensive culture taken in Aska and Surada each. Four women SHGs with 12 members each involved in aquaculture enterprise. It has been observed that, women aquaculture entrepreneurs now trying to increase their aquaculture production which made a tragic shift of aquaculture from extensive to semi-intensive and extensive system. Semi-intensive culture ponds A and B and Intensive culture ponds P and Qtaken for observation for fish production over three years 2021–2023. The mean value of the production as per ANOVA was at par. But, Initial productivity in high input intensive culture pond was high and found to be 1.915 tonnes and 1.898 tonnes /acre reduced to 1.461 tonnes and 1.458 tonnes/acre between 2021 to 2023. Reverse was observed in Semi-intensive ponds as found to be increased from 1.58 tonnes to 1.64 tonnes/acre and 1.59 tonnes to 1.625 tonnes/acre respectively in the same time period. Similarly net profit (mean) per annum was found to be high of INR 2,25,171.3 and INR 2,25,438 in semi-intensive system over three years as compared to intensive system which is found to be low as INR 2,13.591.3 and INR 2,01,441.3. Water quality parameter such as DO,pH, dissolved carbondioxide is found to beyond safe limit in intensive culture ponds as compared to semi-intensive ponds. Due to lack of proper knowledge about intensive aquaculture female stake holders facing problem for optimum output from intensive aquaculture which can be optimized with proper regulation of feeding and maintenance of water quality parameters by acquisition of proper technical knowledge.
