| 摘 要： | 阿根廷滑柔鱼是西南大西洋重要头足类资源,研究其变动、渔场分布与海洋环境的关系是其可持续利用的基础。本文利用分位数回归方法对表温(5m)、表层盐度(5m)、57m盐度及其盐度差、海面高度、叶绿素与阿根廷滑柔鱼钓获率进行回归分析,在中位数和高位数2种情况下分别建立阿根廷滑柔鱼的栖息地指数(HSI)模型,从而揭示西南大西洋阿根廷滑柔鱼栖息地的分布模式。研究表明,本文建立的各分位数回归方程均能较好地解释自变量与应变量的关系(P0.05)。1~5月在60°W以西、42°S~53°S阿根廷沿海的大部分海域,其HIS值基本上在0.7以上;而58°W以东海域的HIS在0.4以下。阿根廷滑柔鱼适宜栖息地分布(HIS大于0.6)有明显的季节变化。

| Abstract: | Illex argentinus is an important cephalopod resource in the southwest Atlantic,the relationship between its resources change,distribution of fishing ground and marine environment is the basis for its sustainable exploitation.In this paper,the regression between sea surface temperature(5m),sea surface salinity(5m),57m salinity and their salinity difference,sea surface height,chlorophyll and jigging rates are analyzed by using the method of quantile regression,the habitat suitability index(HSI) models are est... |
