摘要

-体细胞生长参数用于年龄结构种群评估模型，例如用于评估联邦管理的北凤尾鱼(Engraulis mordax);因此，对增长的不正确估计可能会导致影响股票评估估计的错误。据我们所知，我们完成了第一次对北凤尾鱼(CSNA)中心亚群的体细胞和耳石生长模型的综合调查，该亚群的范围从北加州到墨西哥下加利福尼亚州，通过使用渔业依赖和渔业独立的数据。五个生长模型被拟合到年龄长度数据中，包括两个考虑季节性生长波动的模型，以确定最能描述生长的模型。CSNA存在季节性增长振荡

Modeling somatic and otolith growth of the central subpopulation of northern anchovy (Engraulis mordax) by incorporating seasonality

— Somatic growth parameters are used in age-structured stock assessment models, such as those used to assess the federally managed northern anchovy ( Engraulis mordax ); therefore, incorrect estimation of growth can cause errors that affect estimates from stock assessments. To our knowledge, we completed the first comprehensive investigation to model somatic and otolith growth of the central subpopulation of northern anchovy (CSNA), which has a range from Northern California to Baja California, Mexico, by using fishery-dependent and fishery-independent data. Five growth models were fitted to length- at-age data, including 2 models that account for seasonal growth oscillations, to determine the model that best described growth. Seasonal growth oscillations were found for the CSNA

期刊介绍： The quarterly Fishery Bulletin is one of the oldest and most respected fisheries journals in the world. It has been an official publication of the U.S. Government since 1881, under various titles, and is the U.S. counterpart to other highly regarded governmental fisheries science publications. It publishes original research and interpretative articles in all scientific fields that bear on marine fisheries and marine mammal science.
