Influence of soak time on catch performance of commercial creels targeting Norway lobster (Nephrops norvegicus) in the Mediterranean Sea
Creel catch performance is known to be affected by the soak time in many fisheries. If creels maintain their efficiency over longer periods, increase in soak time should lead to similar increase in catch quantity. However, it is unknown if this relationship is generally true for creel fisheries targeting Norway lobster (Nephrops norvegicus). Should the influence of soak time be known, fishermen could adjust their fishing strategy accordingly and maximize their net earnings. We compared catch performance of creels targeting Norway lobster soaked for one day and two day in the Adriatic Sea. Results were obtained for three crustacean species Norway lobster (Nephrops norvegicus), mantis shrimp (Squilla mantis), blue-leg swimming crab (Liocarcinus depurator) and two fish species poor cod (Trisopterus minutus) and blotched picarel (Spicara flexuosa). Doubling the soak time from one to two days did not lead to doubling the catches and for Norway lobster ; it did not even indicate any increase in catch. For other crustaceans, a slight but not significant increase was estimated. Catches of blotched picarel were significantly lower with the longer soak time, while the results were inconclusive for the poor cod.
