Distribution and abundance of horseshoe crabs in Asajaya mangrove forest

A study on the distribution and abundance of horseshoe crabs was carried out at Asajaya mangrove forest, Sarawak. There were 52 individuals of horseshoe crab had been caught in three stations established; Asajaya Laut (n=8), Jemukan (n=14), and Sadong Jaya (n=30). There were two species identified w...
