Sažetak
Data on distribution and abundance of the knobby swimcrab Macropipus tuberculatus were collected from the by-catch during fishery-biological investigations of the trawling grounds (“Pipeta” Expedition) in the area of the northern and middle Adriatic Sea from 1985 to 1994. The area investigated was approximately 59 000 km2 of the Adriatic continental shelf at predetermined, permanent stations along ten transects over different sediment types at depths of 10 to 430 m. The data obtained (abundance index: number of specimens per km2) were analysed in relation to depth, sediment type, time of day, and the stations where the species was recorded. The highest species abundance was recorded at depths greater than 200 m and in the area of clayey “relict” sand. In the area of investigation, M. tuberculatus was the most abundant on deeper parts of the continental shelf, and especially on the shelf border and upper slope bottoms in the southernmost part of the middle Adriatic Sea.
