AGE, GROWTH, AND CONDITION OF PERCH IN THE SZCZECIN LAGOON

Jerzy Szypuła

 

ABSTRACT



The study involved analysis, performed with standard methods, of length and weight growth of 202 perch individuals caught in November 1999 from the Szczecin Lagoon. The verge coefficient was factored in both when determining the age distribution and when analysing length and weight growth by calculating mean values in age groups (when Kr > 0.50, the number of annual rings was increased by 1).

Key words: perch, growth, mathematical growth models, condition coefficient..
