| Research Abstract |
Culture collection of zooplanktons has been conducted through selection, breeding and field sampling. By feeding them to five species of marine fish larvae, the following findings have been obtained ; 1) Japanese flounder larvae grew better by feeding brackish cladoceran Diaphanosoma celebensis, comparing to the feeding of Artemia franciscana, 2) When small sized zooplanktons were fed to fish larvae with smaller mouth such as seven-band grouper, rusty angelfish, and humphead wrasse, the minute rotifer Proales similis was ingested most efficiently. These larvae shifted preference to larger food according to their growth, and resulting in better growth and survival. Japanese eel larvae(large mouth, but narrow pharynx) could also ingest P. similis. HUFA was successfully enriched to P. similis, and its mass culture could be conducted using batch culture method.
