Abstract:

CPUE standardization is a role in fisheries stock assessment.Different calculating methods for nominal CPUE can affect standardized CPUE which usually is used to index fisheries abundance.In CPUE standardization modeling,nominal CPUE is as a response variable which usually can be calculated in three methods:(1) for every record,CPUE is calculated by catch dividing the corresponding effort,and the all CPUEs were input the model;(2) all fisheries data records are first grouped by one spatial scale(fishing gri...
