摘要
根据2008年8月-11月印尼阿拉弗拉海单船探捕调查的浅色黄姑鱼生物学数据,对浅色黄姑鱼的生物学特性进行了分析。结果为:性成熟度为Ⅱ-Ⅲ期的占79.83%;摄食等级主要为0级和1级,占66.56%;雌雄性比接近1.4:1;体长范围为11.5~52.0cm,优势体长组为17.5~21.5cm和25.5~33.5cm,在经纬度上体长分布差异明显;在优势体长组中,15.5~17.5cm、25.5~32.5cm优势体长组内的雄性个体出现频率明显高于雌性,而在其他体长组内,雌性占优势。
Based on the biological data of Nibea coibor measured from investigation made by otter board trawl in the Arafura Sea of Indonesia during August and November 2008, this paper analyzed the Nibea coibor maturity stages of the biological characteristics. The results indicate: 1 ) Maturity at stages Ⅱ & Ⅲ of the gonad is dominant with percentage of 79.83. 2) The feeding intensity is mainly in class 0 or class 1, totally 66.56%. 3)The female-male ratio is near 1.4: 1, the length range is 11.5 -52.0 cm and the dominant length is 17.5 - 21.5 cm and 25.5 - 33.5 cm, and the difference of the distribution of length is obvious in the latitude and longitude. 4) the length of male is greater than female' s in 15.5 - 17.5 cm and 25.5 -32.5 cm of the length grouping, while female' s length is preponderant in the other groupings.
