Description Results of the experimental fattening of postmoult soft crabs
('Water crabs') o/Scylla oceanica (Dana) in the size 550 g and above
in a brackishwater pond of 0.05 ha area at Cochin during August 1992 -
April '93 are presented. Four fattening trials were attempted under
varying salinity conditions (5-29 ppt) and stocking densities (2.5-5 crabs/
10 m^)for 45-60 days, feeding with trash fish, slaughter house waste
and/or clam meat at the rate of 7% of body weight. Experiments have
shown that 45 days fattening with a stocking density of 1 crab /3mP is
ideal for better survival and economic returns in tide-fed conditions.
Although no significant change was observed in the total weight of crab
during fattening, the average protein content of the meat increased from
8.33% to 14.93% with a decrease in moisture content from 87.15% to
80.93%. Economic analysis of crab fattening trials indicated gross profit
rangingfromRs. 13300 to 50400 in 5-6 crops a year.
