STUDY ON TECHNICAL ASPECTS OF PANGASIUS (Pangasianodon hypophthalmus) FARMING IN MYMENSINGH REGION (Pages : 36 - 42)
M.S. MONIR, M.R. HAQUE AND S. RAHMANThe present study was concerned with existing status of pangasius (Pangasianodon hypophthalmus) farming highlighting its technical aspects in two areas viz. Trishal and Muktagacha Upazila under Mymensingh district during March to December 2008. Needed data were collected with questionnaire by personal interviewing of the respondents. Ponds soil and water samples were collected from three categories (small, medium and large) of pangasius ponds from Trishal to determine the important chemical changes of water and soil. Only some socio- economic aspects varied between the pangasius farmers in two areas regarding their training and education levels. In the areas, about 45% pangasius farmers had leased ponds and lease value was BDT 35,000-45,000/ha/yr. In general, 92% of the pangasius farmers practiced polyculture while only 8% practiced monoculture. The average stocking density was found to be 29,574 fingerlings/ha. About 100% of the pangasius farmers used supplementary feeds for pangasius culture and the average yield of pangasius was 12,000 kg/ha/yr. Generally, there were no remarkable differences between two study areas in terms of technical aspects. The mean values of ammonia-nitrogen and phosphate-phosphorous of water and soil parameters were higher than the suitable level in the pangasius pond. Though the potential of pangasius farming in two regions is mentioned-worthy, it is currently facing a number of constraints such as, lack of quality fingerling, lack of capital, high production cost mostly for feed, proper technological knowledge and low price of pangasius. To improve the overall conditions of the pangasius farmers, it is necessary to upgrade the existing pangasius management practices through institutional initiatives. Download
