(ii) If the parameters of the length-given-age model and the proportion-at-age model are known, it is simple to simulate the ages of the fish with only length data

The individual growth in length (cm/year) for each age group can be calculated from values obtained by comparing the mean length at age of immature capelin one year with the mean

Abundance indices (I) at length with standard error of mean (S) from bottom trawl hauls for main areas of the Barents Sea winter 2001 (numbers in millions).. 1 Abundance indices

A combined acoustic and bottom trawl survey to obtain indices of abundance and estimates of length and weight at age has been carried out each winter (4-6 weeks in January-

A combined acoustic and bottom trawl survey to obtain indices of abundance and estimates of length and weight at age has been carried out each winter (4-6 weeks in January-

The data needed are the catch rates, age and length compositions of all predator species and age-length keys (for each Roundfish Sampling Area) for the principal

3 ~ n age-length key from the bottom trawl survey for cod at Svalbard in September the same year was used to convert the indices from length to age.. Table E5 GREELAND WALIBUT
