胴长

胴长是表征外部形态的变化的最为显著因子，茎柔鱼外部形态各组织间为异速生长，不同海区之间生长模式存在差异。

Mantle length is the most significant factor of charactering changes of the external form . The External morphology of squid organizations grows at different speed , and the growth pattern is different in different sea areas .

个体相对生殖力r/W为4&25粒（平均9粒）。2）怀卵量和个体绝对生殖力与胴长、纯体重及缠卵腺重之间的关系均为直线正相关。

( mean number , 15 ) The individual relative fecundity r / W varies from , 4 to 25 . ( mean number , 9 ) 2.The number of eggs and individual absolute fecundity is a positive linear function of body length , net body weight and nidamental gland .

商用皮重与热胴体重、体长存在极显著的正相关（P0.01），与商用胴体重存在显著的正相关（P0.05）。

The positive correlations of commercial skin weight to hot carcass weight , length were high significant ( P0.01 ), and the positive correlation of commercial skin weight to commercial carcass weight was significant ( P0.05 ) .
