Abstract
Feeding habits of Hippocampus mohnikei (4.1~10.4 cm SL) collected from an eelgrass bed in Dongdae Bay, Korea were studied. H. mohnikei was a carnivore fish which consumed mainly gammarid amphipods. Its diets also included a small amount of caprellid amphipods, tanaids, copepods, mysids, and eelgrass. Gammarid amphipods were the most important prey organisms to the diet of all size classes of H. mohnikei despite smaller H. mohnikei (<4.5 cm SL) fed copepods. H. mohnikei fed on larger sizes of prey as their size increased. The dietary breadth of H. mohnikei were decreased with increasing their size.
