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...
Melatonin rhythms beyond the pineal organ: gene expression of receptors and bio...
Félix de Azeredo Pinto e Melo, Francisca; Oliveira, Catarina; Martín, Ignacio; Manchado, Manuel; Sánchez-Vázquez, Francisco J.; Vera, Luisa M.Fish gonadal melatonin production is still unexplored and could contribute to a better understanding of its role in reproduction control, especially for species with reproductive impairments. This study aimed to comprehend if Senegalese sole testes are an extra-pineal production site of melatonin and if it has seasonal and daily variations. Wild and F1 broodstocks were sampled in the breeding season (BS) and ou...
Melatonin production improves Senegalese sole sperm motility at night, but fail...
Félix de Azeredo Pinto e Melo, Francisca; Ferrão, Leonor; Gallego, Victor; Oliveira, Catarina; Cabrita, ElsaMelatonin is a powerful antioxidant present in fish seminal plasma. This study aimed to understand melatonin's endogenous and exogenous effects on first-generation Senegalese sole sperm quality for sperm management applications. In the first experiment, samples were collected at mid-light (ML) and mid-dark (MD) daytimes, to evaluate the effects on sperm motility. In a second experiment, using confocal microscop...
Effects of dietary supplementation with macroalgae on sperm quality and antioxi...
Félix de Azeredo Pinto e Melo, Francisca; Silva, Nádia; Oliveira, Catarina; Cabrita, Elsa; Gavaia, PauloWithin the efforts in the search for novel feed ingredients in aquaculture, macroalgae are being widely explored due to their diversity of bioactive compounds with considerable prophylactic and therapeutic potential. Plocamium cartilagineum and Sargassum vulgare, have the potential to positively impact fish health, mainly due to their antioxidant properties. The production of Senegalese sole (Solea senegalensis...
