Climate change and the expansion of thermophilic fishes in the northwestern Mediterranean: the importance of studying condition and reproduction to understand the increase in their abundance

A direct consequence of sea warming in the Mediterranean is a increase in the abundance of thermo-tolerant species fish species such as Sphyraena viridensis, Pomadasys incisus, Pomatomus saltatrix and Trachinotus ovatus. The results of this thesis indicated that different thermal-related biological...

Sumario:A direct consequence of sea warming in the Mediterranean is a increase in the abundance of thermo-tolerant species fish species such as Sphyraena viridensis, Pomadasys incisus, Pomatomus saltatrix and Trachinotus ovatus. The results of this thesis indicated that different thermal-related biological responses may exist depending on the species, which in turn strengthens the claim that temperature plays a key role in regulating the physiology of fishes, especially in those warm-water species spreading northwards. Climate change is at least partly responsible for the northward spread and increasing abundance of warm-water species, and their physiological adaptations to the rising sea temperatures might indeed be playing an important role in the establishment into areas these thermophilic fauna did not previously occupy.
