Linf: 12.79, k: 0.42, t0: -0.22 Peharda, M., A. Soldo, A. Pallaoro, S. Mati and P. Cetini 2003. Age and growth of the Mediterranean scallop Pecten jacobaeus (Linnaeus 1758) in the northern Adriatic Sea. J. Shell. Res. 22(3), 639-642. Maturity: 5-6 cm, 20 month: 7 cm
During the last 10 years, after 30 years of intense exploitation, the Italian pectinid Pecten jacobeus stocks had decreased mardedly in the GSA 17. As a consequence of the lack of appropriate managment advice for the fishery, considerng also the environmental deterioration and increasing eutrofication of the northern Adriatic Sea, this resources is now on the brick of the commercial extiction. Considering the distribution observed during SoleMon survey, the Pecten jacobeus could be included in the GFCM shared stock list.
