In 2004 samples have been taken from 943 hauls during 29 commercial fishing trips; 357 000 fish have been measured. From 2002 to 2004 the number of length and weight and measurements, and age determinations could increased by 32, 65 and 156 % resp. Pilot inquiries have been carried out to prepare also the collection of economical date of fishing vessels and of fish processing plants from 2006.

Economics of pond fish culture in some selected areas of Bangladesh

A simple costs and return analysis was done to determine the profitability of pond fish culture in three selected thanas namely Nertakona Sadar, Purbadhala and Kendua under Netrakona district. Cobb-douglas production function model was used to estimate the contribution of key variables to the production process of pond fish culture. It was found that cost of pond fish production was Tk. 10,103/ha/yr and the per hectare fish yield was 943 kgl/yr and the average gross and net return were Tk. 49,515 and Tk. 39,412 respectively. It was found that medium and small farms had the higher yield because of efficient use of production inputs compared to large farms. It was also observed that ownership of pond, number of species and human labour had negative impact on pond fish output, while depth of pond water, farm size, fish seed, fertilizer and artificial feed had significant positive effects on pond fish output.
