The proportion of the egg berried female crabs and the hatching time based on differences in the eggs colour of the blue swimming crab in the crab box apartment

Abstract

Fishermen in Pagagan Village who get the egg-berried female (EBF) of blue swimming crabs can store them in the Crab Box Apartment that has been provided on the coast so that the crabs incubate their eggs. The placement of EBF crabs in the crab box apartment showed fishermen actively participating in sustainable crab management. The EBF crabs are quite varied, especially in egg colour (yellow, orange, brown, and grey). This study used descriptive analysis to identify the EBF crab’s hatching time based on the egg colour that is incubated in the crab apartment. The result showed that the EBF crabs with yellow eggs have an average hatching time of more than 7 days. The orange eggs are, on average 5 days, the brown eggs are about 3 days, and the grey eggs are only 1 day. These hatching time records can also improve the implementation of the crab box apartment, which is a way to minimize the presence of EBF crabs in the supply chain and increase compliance, which leads to sustainability.
