Moreover, we need to find new materials of diets for rearing eel larvae if we are to meet future demand for mass production of glass eels. We formulated test diets from the eggs of the tiger shark Galeocerdo cuvier or the gulper shark Centrophorus atromarginatus and used them in feeding experiments. Larvae fed a diet made from tiger shark eggs or gulper shark eggs survived for 21 days after hatching and had adequate growth rates. However, their survival and growth rates were inferior to those of larvae fed on the diet made from spiny dogfish eggs.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"現在ウナギ仔魚用飼料としてはアブラツノザメ卵を主体とする飼料（SA）が用いられている。この飼料により飼育が可能になったが，サメ卵の中でも特に本種の卵が優れていることは確認されていなかった。加えて，シラスウナギ量産に対応するためには新たな飼料原料を見出す必要がある。本研究ではイタチザメ卵主体飼料（GC）およびアイザメ卵主体飼料（CA）を調製し， SAとの初期飼育の比較試験を行った。その結果 GC 区，CA 区ともにふ化後 21 日まで生残が認められ，GC 区の生残率および両試験区の終了時全長は SA 区に劣ったものの，CA 区の生残率は SA
