| dc.description.abstract | Analyses of stomach contents of Siganus spinus showed that algal availability and size and behavior characteristics of the fish determine what kinds of algae are ingested in the field. Sixty-two algal species were tested during multiple choice food preference trials in the laboratory. Elimination trials and observation tests showed a ranked order of algal preference: (1) Enteromorpha compressa, (2) Murrqyella periclados, (3) Chondria repens, (4) Boodlea composita, (5) Cladophoropsis membranacea, (6) Acanthophora spicifera, and (7) Centroceras clavulatum. An: examination of the morphology of the digestive system showed that the fish are well adapted herbivores, especially toward the filamentous algae. The assimilation values for the adults ranged from 6 to 39 percent; those for the juveniles ranged from 9 to 60 percent. | |
