It was deduced from the capability of searching food and feeding success of the larva, that the mean density of prey organisms is too low to fulfill the food demand during 50 days after hatching. Neverthless some of the larvae manage to get enough food. This would mean that the distribution of prey organisms is not uniform. A possible pattern of the spatial micro-distribution of prey organisms was suggested; the volume of the aggregation of the tiny organisms or swarm was estimated to be 3-952 liters.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1982年から1985年の毎年5月上旬,平戸島近海,北緯33度10分,東経129度20分を中心とする約400平方海里内の19定点における稚魚網(门径130cm,網目幅0.5mm)の50m以浅層傾斜びき試料から選別された浮遊期ヒラメの消化管内容物を調べたところ,年による違いはあるものの空胃の個体が多かった.既往の資料によるヒラメをふくむ主に異体類の稚仔の食物要求量(1日あたり体重の20~45%)と体重に対する消化管の最大充満量の比率(10~20%)とから得られる1日あたりの所要回転数(1~4.5)が,1日12時間に 食物が消化管を通過すると見込まれる回数(2.4~4.0)とが似ていることから,空胃の稚仔は飢餓状態にあると解釈される.しかしながら,ヒラメが全浮遊期間の約80日に要する餌料は 1日あたり0.4~0.9mg(乾重量),この期間の餌料と目される網目幅 100μm のネットで得られるプランクトンの1m²あたり1日あたりの生産量は3~5mg(乾電量)と概算され,このことから1m²あたり3~12のヒラメを養うことができることになるのに対し,海洋現場でのヒラメをふくむ全稚仔魚の分布密度は,1m²あたり0.1~0.5尾にすぎなかった.栄養をおもに焼脚類ノープリアス期幼生に依存する生後50日用においては,北欧産ツノガレイの1種での値を用いるならば,餌料を探索,捕獲できる水量(12時間あたり3~28l)は,ノープリアスの平均分布密度(2μg乾重量/t)のもとで掃破しなければならない水量(12時問あたり9~318l,成長とともに増大)に比べてきわめて少ない.すなわち,プランクトンがまばらに分布していたのでは稚仔の生残や正常な発育に要するだけの餌料を捕獲できない.プランクトンはある場所に集中的に分布して濃密な群を成していなければならず,それが塊状であるとしたときその容積は 3~952lと見積られる.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Seikai
