| 摘 要： | 根据中国鱿钓船于2018年12月在日本海采集的303个舍氏贝乌贼样本，进行基础生物学分析，对其角质颚色素沉积等级进行划分和判定，利用人工神经网络模型分析色素沉积等级与胴长、体质量、性腺成熟度、角质颚形态参数和胃级的关系，并对各生长因子的中位数进行线性拟合。结果显示，胴长对角质颚色素沉积的贡献率最大，为22.90%，其次分别为下头盖长、性腺成熟度、体质量、下喙长和下翼长，贡献率分别为16.50%、14.40%、11.90%、11.70%和11.60%，下侧壁长和胃级对角质颚色素沉积的贡献率较小，分别为6.30%和4.70%。舍氏贝乌贼角质颚的色素沉积与胴长、体质量、性腺成熟度和胃级这4项生长因子的关系均不存在性别间显著性差异。角质颚色素沉积等级与胴长、体质量和角质颚外部形态参数均呈正相关，并随着性腺成熟度的增加而增加，但与胃级的线性关系不明显。研究表明，日本海舍氏贝乌贼角质颚色素沉积等级与胴长、性腺成熟度、体质量和角质颚形态参数均呈正相关关系，可以利用胴长、性腺成熟度、体质量和角质颚形态参数预估色素沉积等级。

| Abstract: | The beak is the main feeding organ of cephalopods which contains abundant biological information and is widely used in cephalopod biology research. In this paper, the characteristics of pigmentation stage in the beak were studied, which provided the basis for the study of fishery ecology of Berryteuthis magister shevtsovi. Based on the 303 schoolmaster gonate squid samples collected in the Japan Sea, we measured the basic biological data which included the mantle length (ML), body weight (BW), sexual maturity stage (SMS), the external morphological parameters (lower hood length, LHL; lower rostrum length, LRL; lower lateral wall length, LLWL; lower wing length, LWL) of the beak and stomach stage (SS), divided and determined the beak pigmentation. The relationships between the beak pigmentation and the ML, BW, SMS, the external morphological parameters of the beak and SS were analyzed by artificial neural networks, and the median values of the samples were fitted linearly. The results indicated that the ML contributed the most to beak pigmentation stage, which was 22.90%, followed by the LHL, SMS, BW, LRL, LWL, which contributed 16.50%, 14.4%, 11.90%, 11.70% and 11.60% respectively, while the LLWL and SS contributed less to beak pigmentation stage, which were 6.30% and 4.70% respectively. The analysis of covariance (ANCOVA) results showed that there was no gender difference in the relationship between the beak pigmentation and ML, BW, sexual maturity stage and stomach stage (P=0.611, P=0.786, P=0.132, P=0.515). The relationships between beak pigmentation and ML (R2=0.9870), BW (R2=0.9148) and the external morphological parameters of the beak (R2=0.9082, R2=0.8768, R2=0.8329, R2=0.7807, R2=0.8938, R2=0.6877, R2=0.7474, R2=0.7787) were significantly relevant. The beak pigmentation stage also increased with the increasing of sexual maturity stage, but there was no significant relevance between the beak pigmentation and stomach stage. This research studied the relationships between various growth factors and beak pigmentation stage, in order to provide scientific basis for further study on fishery ecology and rational development of Berryteuthis magister shevtsovi. The relationships between ML, BW, the external morphological parameters and beak pigmentation stage were significantly relevant, so that we can evaluate the beak pigmentation stage by these growth factors. |
