Phaeodactylum tricornutum biomass in microdiets enhances Senegalese sole (Solea...
Barreto, André; Pinto, Wilson; Rodrigues, Andreia; Rocha, Rui J. M.; Unamunzaga, Carlos; Silva, Tome; Dias, Jorge; Conceicao, LuisMicroalgae are one of the most promising groups of functional ingredients for inclusion in microdiets for Senegalese sole (Solea senegalensis) larvae, supplying components with anti-oxidant effects that may be important during an accelerated stage of development where excessive reactive oxygen substance production leading to oxidative stress may occur. The diatom Phaeodactylum tricornutum complies with such pot...
Microalgal biomasses have potential as ingredients in microdiets for Senegalese...
Peixoto, Diogo; Pinto, Wilson; Gonçalves, Ana Teresa; Machado, Marina; Reis, Bruno; Silva, Joana; Navalho, Joao; Dias, Jorge; Conceicao, LuisSenegalese sole (Solea senegalensis) production presents several nutritional challenges, making this species a good candidate to study the dietary potential of bioactive compounds. Since proper nutrition plays a fundamental role in fish biology, it is necessary to further investigate species-specific and well-balanced diets in order to improve Senegalese sole juvenile farming. Algae have antioxidant properties,...
Optimizing rearing and welfare in Senegalese sole (Solea senegalesensis) broods...
Figueiredo, Filipe; Aragão, Cláudia; Pinto, Wilson; Dinis, Maria Teresa; Oliveira, CatarinaBroodstock rearing conditions and handling procedures should be optimized in aquaculture species in order to benefit fish welfare and guarantee optimal conditions for spawning. In teleosts, basal cortisol levels display daily rhythms, oscillating along the 24 h of the day. In this sense, handling fish at different moments of the day may lead to different stress responses. The present study aimed at investigatin...
Microdiet formulation with phospholipid modulate zebrafish skeletal development...
Martins, Gil; Diogo, Patricia; Santos, Tamara; Cabrita, Elsa; Pinto, Wilson; Dias, Jorge; J. Gavaia, PauloDietary phospholipids' (PLs) content, origin, and profile are known to affect fish development and reproductive performance, but their effects in zebrafish (Danio rerio) nutrition are still poorly investigated. Therefore, this study aimed to assess the effect of practical microdiets containing plant-based and marine PL sources in zebrafish growth, survival, skeletal development, and reproductive performance. Re...
Early transition to microdiets improves growth, reproductive performance and re...
Martins, Gil; Diogo, Patricia; Pinto, Wilson; Gavaia, PauloZebrafish is a model species with a high variability of feeding regimes among fish facilities. The use of live feeds for early life stages is a common practice, and few studies have focused early weaning into microdiets. The lack of standardized feeding protocols among research facilities promotes discrepancies in biological performances, and few studies relate dietary regimes to zebrafish development. The obje...
Can Senegalese sole post-larvae effectively grow on low dietary DHA and lipid l...
Pinto, Wilson; Engrola, S.; Santos, André; Bandarra, Narcisa M.; Dias, Jorge; Conceicao, LuisSenegalese sole (Solea senegalensis) is a highly-valuable flatfish species with interest for diversification of aquaculture in Mediterranean countries. Unlike other fish species known to have a high dietary DHA requirement during the larval stage, several studies have suggested dietary DHA could play a minor role for Senegalese sole during the early developmental stages. This suggestion was recently supported b...
Dietary indispensable amino acids profile affects protein utilization and growt...
Canada, Paula; Engrola, S.; Richard, Nadège; Lopes, Ana Filipa; Pinto, Wilson; Valente, Luísa M. P.; Da Conceição, Gisele CristinaIn diet formulation for fish, it is critical to assure that all the indispensable amino acids (IAA) are available in the right quantities and ratios. This will allow minimizing dietary AA imbalances that will result in unavoidable AA losses for energy dissipation rather than for protein synthesis and growth. The supplementation with crystalline amino acids (CAA) is a possible solution to correct the dietary ami...
