Growth in Nephrops norvegicus from a tag-recapture experiment
Nephrops norvegicus is a commercially valuable fishery in the EU but management of stocks is challenging due to difficulties in aging individuals and calculating growth and biomass production. Growth of N. norvegicus was estimated by releasing 1177 tagged individuals in western Ireland in Summer 2013 and recapturing these in 2014 (n = 207, an average of 344 days later) and 2015 (n = 38, 654-665...
متن کاملSwimmeret Proprioceptors in the Lobsters Nephrops Norvegicus L. and Homarus Gammarus L
1. The morphology, sensory responses and reflex effects of two proprioceptive systems in the swimmerets of the Norway lobster Nephrops norvegicus are described. 2. Two bipolar cells embedded in an elastic strand (strand B) which spans from the sternal rib to the proximal edge of the basipodite respond to stretch of the strand, applied directly or through swimmeret protraction. Powerstroke moton...
متن کاملDiel and seasonal patterns of Nephrops norvegicus (Decapoda: Nephropidae) catchability in the western Mediterranean
Catchability patterns of western Mediterranean Nephrops norvegicus were studied in relation to depth and season by sampling animals during 4 continuous 24 h cycles of trawl hauls at 100 to 110 m and 400 to 430 m in October (near the autumn equinox) and June (near the summer solstice). Bottom light intensity was recorded between consecutive catches. Catch data were transformed into density estim...
متن کاملComparing Trawl and Creel Fishing for Norway Lobster (Nephrops norvegicus): Biological and Economic Considerations
This study compares the fishing activity and landings of the trawl and creel fisheries for Norway lobster (Nephrops norvegicus (L.)) off the Portuguese coast, and evaluates the financial viability of two vessels typical of each fleet. Crustacean trawlers are part of an industrial fleet that, besides Nephrops, targets deep water shrimps. Creels are used by a multi-gear, multi-target artisanal fl...
متن کاملCircadian Oxygen Consumption Patterns in Continental Slope Nephrops Norvegicus (decapoda: Nephropidae) in the Western Mediterranean
The oxygen consumption of Nephrops norvegicus animals collected from the upper continental slope (400 m depth) in the northwestern Mediterranean was monitored under constant conditions of darkness and temperature. Two experiments were performed starting at the beginning of the expected day and at the beginning of the expected night phases, respectively. Mean oxygen consumption values recorded d...
