Fluctuations of landings and environmental conditions in the north-western Mediterranean Sea
18 pages, 7 figures, 3 tables Most of the monthly catches and CPUE of 13 studied commercial species in the coastal waters of the northwestern Mediterranean were signi®cantly positively correlated with run-off of local rivers (RhoÃne and Muga) and the wind mixing index during the spawning season, wit...
