Using the method of inverse growth calculations to determine the age composition of catches for certain species of marine commercial fish

open access: yesИзвестия ТИНРО
New method for constructing size-and-age keys is proposed and tested on the data on size composition of yellowfin sole in commercial catches in the Patience Bay in 1950–2024, with the age of fish determined using the inverse growth calculations ...
