Outline of Final Research Achievements	This study examined effect of non-heated fish larvae-based fish meal diet on survival, development and growth of Japanese flounder larvae. Survival and growth of fish fed diets prepared from fish larvae were lower than that of the control fed on live prey. However, growth and percentage of fish ingested the diet were higher in the group of non-heated fish meal group (p< 0.05). More advanced stage of fish were also seen in fish fed non-heated fish larvae based fish meal diet than that fed heated fish larvae based fish meal diet (p< 0.05). Improved growth seemed to be promoted by intake of dietary water soluble protein rich in non-heated fish larvae based fishmeal.
