全唇裂腹鱼生长模型的筛选
|
摘要
2015年在西藏墨脱县布裙湖采捕到252尾全唇裂腹鱼Schizothorax integrilabiatus样本,通过耳石磨片观察分析其年龄组成,采用特殊Von Bertalanffy(VBGF)、Logistic、Gompertz和幂指数四个生长方程分别模拟全唇裂腹鱼的生长,利用最大似然法估计各模型的参数。结果表明:采集的样本共分为7个年龄组(即1~7龄),以2龄组数量最多。各模型的AIC(赤池信息量准则)和BIC(贝叶斯信息准则)值检验模型的拟合效果显示,VBGF生长方程最适合模拟全唇裂腹鱼的生长,其次为Gompertz、幂指数生长方程,而Logistic生长方程拟合效果最差。VBGF生长方程为:Lt=28.36×[1-e~(-0.14·(ti+0.57))]。由模型间AIC差值可知:Gompertz和Von Bertalanffy生长方程之间的模拟效果差别不太大,都能较好模拟全唇裂腹鱼的体长生长。
Growth model was screened in 252 samples of Schizothorax integrilabiatus collected in Buqun Lake in Medog county, Tibet in 2015, by Von Bertalanffy, Logistic, Gompertz and power exponential growth models, according to the maximum likelihood estimation procedure was used to fit the functions. The growth of Schizothorax integrilabiatus was studied by otoliths and biological parameters to evaluate the age determination and growth simulation of Schizothorax integrilabiatus. The results showed that the fish samples were divided into 7 age classes including the fish from 1 year old to 7 years old, with dominant age of 2 years old in number. Based on the Akaike's Information Criterion(AIC), and Bayesian information criterion(BIC), VBGF model was found to be the most appropriate growth model, followed by Gompertz, and power exponential growth equation, while logistic growth equation fitting effect was the worst. The VBGF function was described as:Lt=28.36×[1-e~(-0.14·(ti+0.57))]. The difference in AIC value of the models revealed that the difference between Gompertz and Von Bertalanffy growth models was not significant, indicating that they can be used in simulation of the growth and stock resources and resource protection of Schizothorax integrilabiatus.
