Abstract
Artificial reef areas can be used for management and conservation of commercially exploited crustacean decapods but their behaviour in these environments is poorly characterised. Acoustic tags were used to study the behaviour of 3 adult spiny lobsters (Palinurus mauritanicus) and 3 adult spider crabs (Maja squinado) over a period of 64 days in summer, evaluating the use of artificial reef areas as suitable sites for re-stocking of overfished decapods. For this purpose, animals were released in a western Mediterranean artificial reef located at 20 m depth, close to a cabled seafloor observatory, which simultaneously recorded temperature, salinity, current direction, current speed and light intensity over the study period. Spiny lobsters lingered in the reef area, whereas the spider crabs left the area 21–45 h after release. These behavioural differences suggested that artificial reefs might be a good area to deploy adult lobsters for re-stocking purposes. The movements displayed by the lobsters during this experiment were not influenced by any of the measured environmental factors, whereas spider crab movements occurred against major current direction, when current speed was intense.
