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.

浮游动物的培养物收集是通过选择、繁殖和现场采样进行的。通过将它们喂养五种海洋鱼类幼体，获得了以下发现； 1) 与喂食丰年虫相比，喂食微咸枝角类 Diaphanosoma celebensis 的日本牙鲽幼鱼生长得更好， 2) 当喂食小型浮游动物如七带石斑鱼、锈神仙鱼和苏眉鱼等嘴较小的鱼类幼鱼时，微小轮虫 Proales similis 的摄入效率最高。这些幼虫根据它们的生长情况，偏好较大的食物，从而获得更好的生长和生存。日本鳗鱼的幼虫（嘴大，咽部窄）也能摄食青鳝。 HUFA成功富集到似青霉中，并可采用分批培养的方法进行大规模培养。
