A study of Environmental effecters on larval recruitment of Musculista senhousia in Hakata Bay

We studied the larval recruitment and the cohort density of Musculista senhousia (MS) which is abundant and highly consumes DO at the bottom of Hakata bay. We proposed the recruitment potential as the max population of MS appeared in study period, and found that the potential is affected bymean bent...

Summary:We studied the larval recruitment and the cohort density of Musculista senhousia (MS) which is abundant and highly consumes DO at the bottom of Hakata bay. We proposed the recruitment potential as the max population of MS appeared in study period, and found that the potential is affected bymean benthic ignition loss and mean AVS throughout the period. We also show that each recruitment is affected by DO and AVS at each recruitment season. ホトトギスガイ (MS) は博多湾に優先的に棲息し, 指標生物となっているばかりでなく, 高密度に棲息するため, 底層における酸素消費への影響が非常に大きい. しかし, その加入については十分知られていない. 本研究では, 加入について場の特性として加入ポテンシャルを提案し, これが底泥の平均強熱減量, 平均底泥表層AVSによって支配されることを示した. また, 加入が加入時期の底層酸素濃度と底泥表面のAVSに支配されることを示した.
