Feeding biology of broadhead sleeper (Eleotris melanosoma) and tank goby (Glossogobius giuris) distributed in Thi Nai lagoon, Binh Dinh province
Abstract
This study is carried out to examine the feeding biology characteristics of the broadhead sleeper (Eleotris melanosoma) and the tank goby (Glossogobius giuris) to take a part in conserving fish resource in Thi Nai lagoon fauna. Fish samples were directly collected from fishermen who are fishing in the lagoon. Feeding biology characteristics of fish as natural food and feeding shift are examined. The results show that the natural food of the broadhead sleeper includes mollusc, crustacean and fish while the tank goby just consumes crustacean and fish. Both goby species exhibite ontogenetic feeding shift. Therefore, based on the results, it can be said that broadhead sleeper and tank goby are carnivorous fish species and also show feeding changes like other carnivorous fishes.
