摘要
浙江北部的嵊泗、中街山和大目洋渔场，位于长江口南缘和杭州湾口外，海区内岛屿星罗棋布，潮流变化复杂，有其独特的海流形式以及温盐分布特征，平均水深35米，海底底质为沙质泥。本文根据9年海调资料和近几年对乌贼的调查(站位见图1)，从水文学角度对其进行综合分析，从中了解环境对乌贼产卵场的影响。
The aim of this investigation is to understand the effect of hydrologic factors on the formation of spawning grounds through an analysis of ocean survey data. This sea area is basically controlled by coastal currents before May; in June after the merging of various current systems, the coastal currents turn out to form a long, narrow frontal zone,and if the eastern wind prevails at that time,a better catch may be expected.
