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.

通过选择、繁殖和野外取样进行了浮游动物的培养收集。把它们喂给五种海鱼幼虫，结果如下：(1)以半咸淡水枝海Diaphanosoma celebensis为饵料，比以Artemia franciscana为饵料生长较好；(2)以小型浮游动物为饵料，以七带石斑鱼、角鱼、座头濑鱼等口部较小的鱼类为饵料，以微小轮虫Proales similis为饵料。这些幼虫根据自己的生长情况，对较大的食物有不同的偏好，从而更好地生长和存活。日本鳗鲡幼虫（嘴大，咽窄）也能吞食类似鳗。成功地将HUFA富集到相似草中，可采用批量培养法进行大量培养。
