Mark-recapture experiments with painting were carried out supplementally in Igarashi beach. In 1987, the growth of the clam was estimated at 3-4, 10, 18, 32 and larger than 45mm in the 1st, 2nd, 3rd, 4th and 5th winters after birth, respectively.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1986年から1989年にかけて新潟市五十嵐浜において毎月1回の定期採集調査と標識再捕調査を行い,当海域のコタマガイの成長について以下の結果を得た.1.採集は枠取り法(目合1mm),稚貝網(目合2mm)およびジョレン網(目合10mm)によって行った.枠取り法は殻長1.5~5mm,稚貝網は3.5~12mm,ジョレン網は14mm以上の採集に有効であった.2. 1987年の12月時点における各年級群の殻長モードは0才群3~4mm,1才群10mm,2才群18mm,3才群32mm,4才群45mm以上と推定された.各年級群における殻長の分散は非常に大きく,成長の速い群と遅い群が混在していると考えられた.3. 殻長20mm前後において夏期に1ヶ月間で6mmも成長する可能性が示されたが,全体的には上記の遅い成長パターンに従う.4.放流再捕結果は上記の成長パターンよりも成長が悪く,殻長20mm以下ではほとんど成長しなかった. これは放流および標識に用いたペイントによるストレスのためと考えられた.天然貝の成長は放流貝よりも良く,上記の成長パターンに従うと考えられた.5. 輪紋は年齢形質として有効であるが,海域によっては冬期以外にも形成されるため注意を要する.殻長20mm以下の輪紋の判定は微妙で誤りやすい.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan
