The effect of ice trash fish, Leiognathus equula (Forsskål, 1775) (Percomorphi, Leiognathidae) and oyster, Crassostrea iredalei (Faustino, 1932) (Ostreida, Ostreidae) on the growth and mating of the mud crab, Scylla paramamosain Estampador, 1950 (Brach...

What is it about?

The growth study used the crabs with a total body weight of 55.07±4,61g ind.-1 and carapace width 65,9±3,05 mm ind.-1 for females, then total body weight 60.96±1.93 g ind.-1 and carapace width 65,39±1,89 mm ind.-1 for males. The crab was cultured individually in a plastic box that floated on the water's surface in a 90-ton concrete cement tank for four months. The fast-growing body weight and carapace width males found in treatment B (fed trash fish and oyster meat) compared to the average body weight and carapace width males in treatment A (fed trash fish only). _x000D_ The growth of female total body weight and carapace width in treatment B and C(fed oyster meat) was faster than that of females in treatment A. Crab mating was found from July 2020 to January 2021, with the highest intensity in September and October 2020. In November, December, and January, mating intensity decreased. The smallest size of female crab mating was 135 g with a carapace width of 91.1 mm. The mature male crab size mating from July 2020 to January 2021 mainly at an individual size of 300-400 g. (Carapace with 101.4-123.7 mm). Only 6.4% of males mate at the individual bodyweight 250-299g. _x000D_ _x000D_
