The Impact of Climate Change on Bivalve Farming: Combined Effect of Temperature and Salinity on Survival and Feeding Behavior of Clams Ruditapes decussatus

European clam ( Ruditapes decussatus ) is one of the most relevant emergent bivalve species from aquaculture sector in Europe with high economic value. Climate changes represent a potential limiting factor to this activity, directly interfering survival and behavior bivalves. Severe fluctuations temperature along periods heavy rainfall or drought that significantly change salinity can promote physiological stress bivalves, resulting behavioral responses and, extreme cases, leading mortalities. This study aimed evaluate combined effect on mortality feeding R. . Juveniles adults were exposed ranges (5°C–35°C) (0–40). Mortality registered every 24 h each 120-h trial. A control range was set between 15°C 23°C, where considered as normal scenario. Our data suggested 15 “turning point,” point which occurred distinct patterns behavior. The results evidently indicate abrupt reductions sharp increases will lead decussatus. revealed be more sensitive increase less saline environment, suffer greater faster mortalities, resistant extremely temperatures under conditions. sporadic are predicted occur south due climate contribute compromise recruitment clam, thus threatening production consequently impacting sector.
