所罗门群岛海域长鳍金枪鱼的垂直分布与环境因子的关系

Relationship Between Vertical Distribution of Albacore Tuna Thunnus alalunga and the Concerned Environmental Factors in the Solomon Sea

根据2010年8-11月在中西太平洋所罗门群岛海域金枪鱼延绳钓作业,研究了长鳍金枪鱼的垂直分布与环境因子的关系。结果表明,在所罗门群岛海域,长鳍金枪鱼的最适水层为130.00～160.00 m,最适水温范围为22.00～24.00℃,最适盐度范围为35.70～35.80;长鳍金枪鱼活动较频繁的水层范围为130.00～190.00 m,水温范围为20.00～26.00℃,盐度段为35.60～35.90。

This paper analyzes the relationship between Thunnus alalunga vertical distribution and the temperature, salinity in the Solomon Sea. The results indicate that in the Solomon Sea the optimal swimming depth, water temperature and salinity range of the Thunnus alalunga were found to be 130.00-160.00 mm, 22.00-24.00℃, 35.70-35.80 respectively. The common swimming depth, water temperature and salinity range were 130.00-190.00 mm, 20.00-26.00 ℃, 35.60-35.90 respectively.
