| Abstract |
In vitro experiments on the predatory behaviour of the Portunid crabMacropipus holsatus indicate that it is not a very efficient predator of brown shrimp, Crangon crangon. Only about 2 % of the shrimps in the test units were killed and partly eaten by the crabs. These findings are compared to the results of earlier investigations on the food composition and feeding behaviour of Macropipus holsatus by Amrom (1961). Previous assumptions on the detrimental effect of the swimming crab on the shrimp stock and fishery should be attenuated. |
