为给金乌贼渔业的可持续发展提供依据,通过形态学观察及生物学测定,初步研究了山东日照岚山头近海金乌贼Sepia esculentaHoyle,1885的外部形态特征和生物学特性(胴长与体重组成、生长参数相关关系等),并结合相关资料,对其生活史进行了讨论。研究结果表明:金乌贼胴长(ML)与体重(TW)之间的关系为:TW幼体=6.0×10-4ML2.762 6,TW♀=6.0×10-4ML2.767 1,TW♂=12.0×10-4ML2.585 6;金乌贼为异速生长型,其生长迅速、个体生长差异较大;5~6月为金乌贼繁殖季节,成体交配产卵后死亡,属1年生头足类。
In order to provide the basis for the sustainable development of the golden cuttlefish fishery, the morphology and biological characteristics of Sepia esculentaHoyle, 1885 in Lanshan, Shandong Province were studied by morphological observation and bioassay (body length and body weight, Growth parameters, etc.), and combined with relevant information on its life history were discussed. The results showed that the relationship between the body length (ML) and body weight (TW) of golden cuttlefish was as follows: TW larvae = 6.0 × 10-4ML2.762 6, TW♀ = 6.0 × 10-4ML2.767 1, TW♂ = 12.0 × 10-4ML2.585 6; golden cuttlefish allometric growth type, its rapid growth, the individual differences in growth; May to June for the golden squid breeding season, the adult mating death after oviposition, is a one-year-old cephalopods.
