The high mortality in the early stages of life is a common phenomenon in fish and other species, but it is little studied due to its complexity. A study by the University of Barcelona and the Centre for Advanced Studies of Blanes (CEAB-CSIC) has analysed whether this mortality in the sharpsnout seabream ( Diplodus puntazzo ), a species of the Mediterranean with an important commercial interest, occurs by chance or whether it is genetically determined. The results, published in the journal Scientific Reports , show that the survival of this fish in the first months has a genetic basis and it is associated with the time of birth. The study is led by Marta Pascual, lecturer at the Faculty of Biology and member of the Biodiversity Research Institute ( IRBio ) of the UB and Enrique Machpherson, research professor at CEAB-CSIC. Among the participants of the study are Héctor Torrado (CEAB-CSIC and IRBio), Cinta Pegueroles (IRBio), Carlos Carreras (IRBio) and Nuria Raventós (CEAB-CSIC).
