The influence of defined ante-mortem stressors on the early post-mortem biochemical processes in the abdominal muscle of the Norway lobster, Nephrops norvegicus (Linnaeus, 1758)

A rapid onset, post-capture muscle necrosis in the Norway lobster, Nephrops norvegicus (L.), from the West coast of Scotland

A post-capture, abdominal muscle necrosis of rapid onset has been identified in Norway lobsters, Nephrops norvegicus (L.), captured off the West coast of Scotland. Economic losses, as a result of the mortality of these animals in transport, were encountered by Scottish wholesalers during the summer and autumn of 1999. Affected animals show a characteristic whitening of individual muscle fibres ...

Determination of biogenic amines and endotoxin in squid, musky octopus, Norway lobster, and mussel stored at room temperature.

Little research has been published on the indicators of spoilage in Mediterranean molluscan shellfish and crustaceans. Thus is why we studied changes in the concentrations of endotoxin and four biogenic amines (histamine, putrescine, tyramine and cadaverine) in European common squid (Loligo subulata, Lamarck, 1798), musky octopus (Eledone moschata, Lamarck, 1798), Norway lobster (Nephrops norve...

Studies on the Chemical Composition of Muscle Tissue Ii. the Abdominal Flexor Muscles of the Lobster Nephrops Norvegicus (l.)

Effects of emersion and re-immersion on physiological and immunological variables in creel-caught and trawled Norway lobster Nephrops norvegicus.

Immune defence in creel-caught and trawled Nephrops norvegicus was investigated to assess a possible relationship between phenoloxidase (PO) activation and the total haemocyte count (THC). Capture, capture method and emersion evoked physiological and immunological responses that may have implications for the ability of N. norvegicus to survive the effects of such stressors. Haemolymph THC was a...

Comparing 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...
