Bivalves are one of the most diets found in Carcinoscorpius rotundicauda gut.
However, the feeding capacity for specific bivalves was rarely reported. This
study determines the feeding capacity of C. rotundicauda toward different types
of bivalves. C. rotundicauda were given 7-20 individuals of cockles in separate
tanks individually (repeated for mud clams, oysters and mussels). The number
of eaten bivalves was counted twice a day at 8am and 6pm (day and night
feeding) for 14 days. The feeding capacity for mussels was high (15 individuals)
followed by mud clams, oysters and cockles. This feeding capacity may be
influenced by the higher mortality rate of mussels compared to others. There
is no difference in day and night feeding, with similar pattern shown by both
male and female. Therefore, release of horseshoe crabs into Setiu Lagoon for
conservation purpose might not affect catch of bivalves for sale by local
communities in Setiu.
