Percentage-weight and combined methods of processing power Pacific cod (Gadus macrocephalus)
The weight-percentage and combined methods of processing the nutrition of Pacific cod are presented. It is shown that both methods accurately reflect the change in cod consumption with the growth of both the main food groups of aquatic organisms and the predominantly consumed representatives of these groups. The methods show very close (combined) or close (weight-percentage) values (% by weight) of the consumption of the main food groups by cod in general. Both methods correctly accurately reveal the most significant forage aquatic organisms of different size groups of cod for feeding. However, their sequence in importance for individual size groups (mainly small-sized ones) is distorted. The most accurate of the presented methods is the combined method.
