Testis transcriptomic analyses reveal the effects of an algae feed on sperm qua...
Félix de Azeredo Pinto e Melo, Francisca; Raposo de Magalhães, Cláudia; Marrero Alemán, Carlos; Duarte, Daniel Filipe Correia; Parente, PedroThe usage of dietary algae antioxidants to improve fish reproduction is under-explored, especially in terms of the male reproductive system. In this experiment, 6 % of a blended meal of Phaeodactylum tricornutum and Gracilaria gracilis was incorporated in Senegalese sole broodstock feed, to evaluate the effects on sperm quality of F1 males throughout the breeding season. For that, two groups of breeders were fe...
The use of egg quality parameters to evaluate the effect of a diet supplemented...
Ramos Júdez, Sandra; Fatsini Fernández, Elvira; Marrero Alemán, Carlos; García-Pichel, Candela; Parente, Pedro; Medina, D.; Castro, C.; Cabrita, ElsaEnhancing egg quality can be achieved by improving breeders’ diet through the antioxidant content, as oxidative stress could adversely affect egg quality. Micro- and macroalgae species are natural sources of antioxidants and other essential nutrients that can be incorporated in fish feeds. In this study the quality of Scophthalmus maximus eggs were compared between breeders fed a commercial (non-supplemented) d...
Optimising sperm quality in flatfish through algae blend fish feed supplementation
Parente, PedroFlatfish production is a growing sector in the Atlantic region, with turbot (Scophthalmus maximus) and Senegalese Sole (Solea senegalensis) being two important species with high market value in southern European countries. However, reproductive dysfunctions like the inability of captive bred individuals spawning spontaneously, poor sperm quality and quantity, still affect the obtention of progeny. Broodstock nu...
