Under these circumstances, it is likely that the Nephrops fisheries in the Irish Sea are contributing to the poor status of whiting, and preventing it from recovering. You can increase the sustainability of the scampi you eat by choosing Nephrops caught using creels. What is it: Nephrops norvegicus (also known as Norway lobster, langoustine, scampi, and Dublin Bay prawn) is a mud burrowing marine decapod crustacean. For the purposes of management and stock assessment, Nephrops are split into a number of stocks or ICES 'functional units' (FUs) based on the discrete patches of mud which they inhabit. In terms of Nephrops habitat, the sediments of interest are ‘muddy sand’, ‘sandy mud’ and ‘mud’. ‘Muddy sand’ is roughly equivalent to sediment comprised of 10-50% silt and clay, ‘sandy mud’ 50-90% silt and clay and ‘mud’ 90% or higher silt and clay. 5 Nephrops norvegicus adults prefer to inhabit muddy seabed sediments, with more than 40 percent silt and clay.

Nephrops distribution is limited by the extent of suitable muddy sediment in Nephrops in Division 7b (Aran Grounds, FU17) has been scored low risk. The stock is assessed annually by ICES. The Total Allowable Catch (TAC) is set for ICES Subarea 7 as a whole, which could lead to increases in fishing effort on individual functional units of Nephrops. Nephrops norvegicus grows to a maximum total length of 25 cm (including the tail, carapace and clawed legs), although is normally between 18-20 cm (Fish & Fish, 1996). The generally recognized standard measurement for Nephrops norvegicus is carapace length (CL).

Taxonomic edit history. Habitat: N. norvegicus can be considered a “mud-loving” species, not restricted to a particular biocenosis or to a biocenotical zone (Froglia and Gramitto, 1981).

Distribution: It is registered in the East Atlantic Ocean, from Norway and Iceland to Morocco and the Mediterranean. Nephrops norvegicus is a species with separate sexes. Males are, on an average, larger than females. Males are, on an average, larger than females. Although Fisher et al. (1987) stated that its maximal total length is 24 cm, larger specimens have been caught, primarily in the northern Adriatic.

This mechanism could be particularly crucial for the larvae of the heavily fished crustacean Nephrops norvegicus (L.), as their sediment requirements highly restrict where they are able to settle.
