On length-weight relationships. Part II: Computing mean weights from length statistics
Type: Journal Article
Assuming a known length-weight relationship, the formula for calculating the mean weight from grouped length statistics is recapitulated. Then a simple analytical method for calculating mean weight from basic length ...
