MetadataShow full item record
Experimental culture of crabs, fish and prawns was conducted in a pond measuring approximately 800 m2 in Kwetu training center, Mtwapa, Kenya. The objective was to evaluate the success, potential and economic viability of the culture system. Crabs were placed in 6 experimental cages measuring 2 x 2x 0.5m for 3 months in different stocking densities in order to compare their survival. The three densities were 3.0, 6.0 and 9.0 crabs/m2. Other crabs were placed in compartments made of locally available ‘fito’ designed in eight compartments measuring 1x1 x 0.9 ft for crab fattening. In the same pond, 2045 juvenile prawns Penaeus monodon and P. indicus measuring between 21-25 mm in total length were stocked inside the pond to grow, together with milkfish and mullets. At the end of 3 months, harvesting was done for crabs, and after 6 months for prawns and fish. Environmental variables were measured in the pond biweekly during the six month period. This included, temperature, sali.....
