Estimating size dependent diet, advection, diffusion, catchability and mortality applying a normal distribution model to spreading of released turbot
In a field experiment, breed turbot of an average length between 7–25 cm was released into a small bay. During the following week; diffusion rate, mortality and catchability of the released fish was estimated daily, by using a normal distribution model. In this model the size of the fish was incorpo...

Summary: | In a field experiment, breed turbot of an average length between 7–25 cm was released into a small bay. During the following week; diffusion rate, mortality and catchability of the released fish was estimated daily, by using a normal distribution model. In this model the size of the fish was incorporated in such a way, that it was possible to retrieve information about how each of the estimated parameters depended on the fish size. In addition, the length of the prey items found in the stomach was measured and compared to the prey length available in the habitat. Turbot was found to adjust to eat the available prey fast, after 3 days approximately 100% had detectable signs of prey in their stomach. |
