On the growth of the European spiny lobster, Palinurus elephas from Sardinian waters (central western Mediterranean Sea)

Abstract

Growth of spiny lobsters Palinurus elephas was investigated using tagging data. A total of 4044 lobsters were tagged and released between 1997 and 2004 in an area off central‐western Sardinia, Italy, where fishing is banned. The growth increments of 248 lobsters, recaptured inside the no‐take area and in the surrounding zones, were recorded and analysed with two different procedures, and von Bertalanffy growth parameters were estimated for each sex. Males showed a higher asymptotic carapace length than females (167.9 versus 120.2mm). Growth increments recorded inside and outside the no‐take area did not reveal any density‐dependent effects on females. Small but non‐significant differences were evident for males, showing faster growth in lobsters caught outside the no‐take area.
