Creek`s Aquaculture Techniques in Rangamati Hill Tracts of Bangladesh
Journal Title: Annual Research & Review in Biology - Year 2017, Vol 13, Issue 2
Abstract
An experiment was conducted in nine suitable (average .10±2 ha) creeks of Rangamati hill tracts Bangladesh viz., of Langadu, Naniarchar and Sadar Upazila for evaluating growth, survival and production performance of Indian major carps (Labeo rohita, Catla catla, Cirrhinus mrigala) in a completely randomized design into three different treatments with three replications for a period of one year. Stocking density, growth, survival was checked periodically and total yield calculated from stocking and harvesting data. A significant spatial variation in specific growth rate (SGR) and yields was found despite uniform stocking densities, attributable to variation in environmental parameters. Among the results rohu was found to have comparatively higher SGR of 1.51±0.55 in Naniarchar where as langadu creek was reported with higher SGR of 1.46±0.94, 1.57±0.41 and 1.46 ±.64 for rohu catla, and mrigal. Rangamati sadar Upazilla creek was found to be conducive to Catla with a SGR of 1.55±.78. In general, higher gross and net productions were reported from Sadar Upazilla, Langadu and Naniarchar creeks, suggestive of its suitability for developing creeks aquaculture technology. However research findings will help the community of Chittagong hill tracts by giving appropriate technology for sustainable fish production in creeks.
