根据1998年5、8、11月和1999年2月在闽东北外海26°00′~28°00′N,120°00′~125°30′E的虾类调查资料,研究分析了该海域高脊管鞭虾(Solenoceraalticarinata)数量分布及生物学特征。结果表明:5、8、11和2月调查海域高脊管鞭虾平均密度指数分别为34·7、13·8、4·55和2·89kg·km-2;其数量分布具有明显的季节性,以5和8月数量为多,11和2月数量较少;分布区域以调查海域的东北部水域为主,以27°00′~28°00′N,122°30′~124°30′E水深80~100m海域数量为多;渔获体长范围为41~129mm,优势体长组为80~100mm,占44·7%,雌虾个体明显大于雄性个体,雌虾平均体重为12·0g,雄虾平均体重为8·3g,雌雄性比为1:0·66,生殖盛期为8~11月,不同季节和性别摄食强度没有明显差异。
According to the survey data of shrimp at 26 ° 00 ’~ 28 ° 00’N and 120 ° 00’ ~ 125 ° 30’E in the waters off Fujian Northeast in May, August and November 1998 and February 1999, Quantitative distribution and biological characteristics of Solenoceraalticarinata. The results showed that the average density index of R. verticillata in investigated waters in May, August, November and February were 34.7, 13.8, 4.55 and 2.89 kg km-2, respectively. The quantity is mostly in May and August, but less in November and February. The distribution area is dominated by the northeastern waters of the survey area, with 27 ° 00 ° -28 ° 00’N and 122 ° 30 ° -124 ° 30’E was 80-100m deep. The catch range was 41-129mm, and the dominant body length was 80-100mm, accounting for 44.7%. The average body weight of females was significantly higher than that of males 12 · 0g, the average body weight of males was 8.3 g, the male-male ratio was 1: 0.66, and the reproductive season was from August to November. There was no significant difference in feeding intensity between different seasons and sex.
