A detailed investigation of a small area of sea bed occupied by the Norway lobster Nephrops norvegicus (L.) was carried out by diving and television observations at depths of 30 m in Loch Torridon, Scotland. The density of burrows was 1/2 m2, but only a proportion of these were occupied by N. norvegicus. Although about 70% of the larger burrows were occupied by N. norvegicus, giving a density of 1 lobster/8 m2, very few juveniles (carapace length less than 30 mm) were found in the area. Many of… 

Observations on the burrows and burrowing behaviour of two mud-dwelling decapod crustaceans, Nephrops norvegicus and Goneplax rhomboides

TLDR
The burrows of the Norway lobster Nephrops norvegicus and of the crab Goneplax rhomboides were studied in Loch Torridon, Scotland and it is suggested that the fossorial habit was adopted very early by decapods.

The Behaviour of the Norway Lobster , Nephrops norvegicus ( L . 1 , During Trawling

Introduction The Norway lobster, Nephrops norvegicus (L.) (Plate I), commonly called the "prawn", is widely distributed around Scotland and supports an important inshore fishery (Howard, 1982).

First observations on Nephrops Norvegicus (L.) Burrow Densities on the Continental Shelf off the Catalan Coast (Western Mediterranean)

The density of Nephrops norvegicus burrows on the lower continental shelf (100-120 m depth) off the Catalan coast (western Mediterranean) was estimated by underwater photography. A total of 68

Feeding energetics of the Norway lobster, Nephrops norvegicus in the Firth of Clyde, Scotland

TLDR
The recent feeding history was observed to have a marked effect on metabolic rate and the MO2 significantly decreased following 8 and 12 weeks of starvation, and rapidly increased again after re-feeding, which suggested periodicity of foraging with gut contents being lowest during the afternoon.

Field observations on the emergence rhythm of the Norway lobsterNephrops norvegicus, using different methods

TLDR
Day/night variations in the size composition of catches suggest that relatively more time is spent out of the burrow with increasing size, while the use of bait in some experiments confirmed that emergence is essentially a feeding activity.

Burrow emergence rhythms of Nephrops norvegicus by UWTV and surveying biases

TLDR
This paper deals with the discrimination of burrow emergence and door-keeping diel behaviour in Nephrops norvegicus, which is one of the most commercially important fisheries in Europe, and calls into question the current burrow occupancy assumption which may not hold true in all FUs.

Alteration of burrow‐related behaviour of the norway lobster, nephrops norvegicus during infection by the parasitic dinoflagellate hematodinium

TLDR
Altered burrow‐related behaviour of N. norvegicus under a 12 h light: dark regime in aquarium conditions is compared with the behaviour of lobsters infected by the parasitic dinoflagellate Hematodinium, which led to a more than ten‐times increase in the percentage of the day spent out of the burrow by infected lobsters.

The burrows of Nephrops norvegicus (L.)

TLDR
Observations made by divers, combined with aquarium experiments, show that the Norway lobster digs burrows with, usually, two openings in the bottom sediment, and individuals of both sexes and of most size classes are found in such burrows.

TLDR
The Dublin Prawn or Norway Lobster, Nephrops norvegicus (L.), is widely distributed on soft muddy bottoms, usually between 10 and 50 fathoms, and extends as far south as the coast of Morocco.

TLDR
The persistence of the pattern of nocturnal activity for several days under conditions of constant low light intensity confirmed that emergence and subsequent activity were under rhythmic control.
