中文摘要:
      角质颚是头足类主要的摄食器官,被广泛用于头足类渔业生物学研究。[目的]本文研究角质颚色素沉积特性,为后续利用角质颚色素沉积研究舍氏贝乌贼(Berryteuthis magister shevtsovi)的渔业生态学提供基础;[方法]本文根据中国鱿钓船于2018年12月在日本海采集的303尾舍氏贝乌贼样本,对其基础生物学进行测定、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了色素沉积等级与胴长、体重、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了线性拟合。[结果]结果显示,胴长、性腺成熟度、体重和下头盖长对色素沉积的贡献率较大,所占比重分别为22.90%、14.40%、11.90%和16.50%。舍氏贝乌贼角质颚的色素沉积与胴长、体重、性腺成熟度和胃级这四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、体重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。[结论]日本海舍氏贝乌贼角质颚色素沉积等级与胴长、体重和角质颚形态参数均呈正相关关系,可以利用胴长、体重和角质颚形态参数预估色素沉积等级。
英文摘要:
      The beak was the main feeding organ of cephalopods which was widely used in cephalopod biology research. [Object] 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;[Method] Based on the 303 schoolmaster gonate squid samples which collected in the Japan Sea, we measured the basic biological data,divided and determined the beak pigmentation. The relationships between the beak pigmentation and 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 were analyzed by artificial neural networks, and the median values of the samples were fitted linearly; [Results] The results indicated that the contributions of ML, sexual maturity stage, BW and lower hood length (LHL) were large, accounting for 22.90%, 14.40%, 11.90% and 16.50% respectively. The analysis of covariance (ANCOVA) results showed that there was no gender difference between the beak pigmentation and ML, BW, sexual maturity stage and stomach stage. The relationships between beak pigmentation and ML, BW and the external morphological parameters of the beak were significantly relevant. The beak pigmentation stage also increased with the increasing of sexual maturity stage, but there was no significantly relevant 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 schoolmaster Berryteuthis magister shevtsovi; [Discussion] The relationships between ML, BW, the external morphological parameters and beak pigmentation stage were significantly relevant, so that we can guess the beak pigmentation stage by this growth factors.
