Table 2 
Mean observed length-at-age for gill-net (targeted catch), purse-seine, and trawl catches. The symbol SD denotes the standard 
deviation, n denotes the number of individuals examined and “ — “ denotes that a value could not be calculated. ANOVA was per- 
formed only for the age classes with n greater than 10.
