Egg hatching success in an Asian horseshoe crab, Tachypleus gigas incubated in different sediment as substrate

Tachypleus gigasis one of the Asian horseshoe crabs facing threats from human exploitation and habitat degradation. This study aimed to determine the effect of using sediment as substrate in the egg incubation procedure. Freshly laid eggs clutches were collected from a nesting beach during...
