In the experiment on the selectivity to shape of rotifer lorica (L and S-type), the larvae of the three species showed similar selectivity though the shape of the lorica and the anterior spines were different. In terms of rotifer size selection, the larvae of the three species positively selected smaller rotifer at the onset of feeding. However, the selection shifted to larger rotifers on 10 DAH for spotted halibut and 16 DAH for yellowtail and flathead larvae. By comparing the selectivity based on mouth size, flathead larvae showed strong selectivity to larger rotifers than spotted halibut and yellowtail larvae., 日本水産学会誌, 74(3), pp.380-388; 2008}, pages = {380--388}, title = {大きさと形の異なるシオミズツボワムシ 3 株に対するホシガレイ,ブリ,ヨシノゴチ仔魚の摂餌選択性}, volume = {74}, year = {2008} }
