Abstract

We here report some data on the biology and population structure of Plesionika narval (Fabricius,1787) captured along the coast of the island of Ustica in the southern Tyrrhenian Sea. Specimenswere collected monthly from January to October 2000 using commercial traps at depths rangingfrom 15 to 100 metres. The carapace length (CL) of females ranged between 7.0 and 26.0 mm,and between 7.0 and 17.0 mm for males. Three modes were identified in the cumulative frequencydistribution for females but only two for males. In females, the third modal value was observedonly at the deeper sample sites. The Von Bertalanffy growth parameters and performance index ϕwere K = 0.65 y−1, CL∞ = 27.4 mm CL and ϕ = 2.62 for females, and K = 0.71 y−1,CL∞ = 17.8 mm CL and ϕ = 2.28 for males. Ovigerous females were found during the entireperiod of the investigation, indicating that this species spawns all year round. We compared ourresults with other data recorded in the literature.
