The feeding rate of a parasitic gnathiid isopod on fish was examined. Individual fish, Hemigymnus melapterus, were exposed to gnathiid larvae and sampled after 5, 10, 30, 60, and 240 min. I recorded whether larvae had an engorged gut, an engorged gut containing red material, or had dropped off the fish after having completed engorgement; variation among sampling times and larval stages was anal...

  This study was conducted to evaluate the efficacy of live food (Artemia urmiana) and commercial diet in rearing of Oncorhynchus mykiss larvae. Experiment started when larvae were 0.12g in weight. Triplicate groups of fish were offered one of four treatments: (1) a commercial starter food (2) live Artemia urmiana nauplii (for 3 days) (3) live Artemia urmiana nauplii (for 7 days) and (4) combin...
