摘要:
The food and feeding habits of the influent and subinfluent species (11 fish, 4 shrimps, and 4 crabs) in Hawaiian fish ponds were analyzed to ascertain the biotic interaction. The dominant species were treated in a similar way and reported upon earlier. The ponds are virtually autarchic, and the available food supply is almost totally dependent upon the physical features of the biotope. Microbenthos and detritus were found to support most of the herbivorous species while larger benthos, emergent halophytes, and plankton play minor roles. The animal assemblage within the ponds includes not only herbivores and omnivores but is replete with carnivores, several of which are voracious and reach a large size.
