Fish held at high stocking densities are generally exposed to chronic stress situations that impose severe energy demands and may predispose the fish infection. Senegalese sole Solea senegalensis (Kaup) juveniles (78.8±18.9 g body weight) were maintained low (LSD; 4 kg m−2 end of experiment), medium (MSD; 9 m−2) (HSD; 14 during a period 63 days. Although disease outbreaks observed in reared HSD, growth food consumption did not vary among different treatments. Results from plasma cortisol...
Abstract Senegalese sole was one of the earliest identified candidate species with high potential for aquaculture diversification in south Europe. Its culture has been possible, and commercially attempted, several decades, but intensive production slow to take off. This explained mostly by serious disease problems, mortality at weaning, variable growth poor juvenile quality. However, a strong sustained research investment that started eighties led better understanding requirements...
Abstract Immune nutrition is currently used to enhance fish health by incorporating functional ingredients into aquafeeds. This study aimed investigate the connections between tryptophan and network that regulates communication pathways neuroendocrine immune systems in European seabass ( Dicentrarchus labrax ). When was supplemented diet of unstressed fish, it induced changes hypothalamic-pituitary-interrenal axis response stress. Tryptophan-mediated effects were observed expression...
Infectious diseases and fish feeds management are probably the major expenses in aquaculture business. Hence, it is a priority to define sustainable strategies which simultaneously avoid therapeutic procedures reinforce immunity. Currently, one preferred approach use of immunostimulants can be supplemented diets. Arginine versatile amino acid with important mechanisms closely related immune response. Aiming at finding out how arginine affects innate status or improve disease resistance...
A proposta deste texto é refletir sobre a cartografia como experiência metodológica, na pesquisa em educação, realizada partir mapeamento dos processos comunicacionais e redes de difusão do conhecimento grupos uma universidade pública com característica peculiar, multicampia. orientou-se pelos princípios da multirreferencialidade rizoma, abordagem qualitativa tendo método cartografia. inspiração buscada está voltada para os campos das Ciências Sociais Humanas e, mais que o território no seu...
The aquaculture industry must continue to reduce its reliance on finite marine ingredients and promote biocircularity enhance sustainability. This study evaluated the effects of no‐fishmeal (FM) diets fish protein hydrolysates (FPHs) growth performance, antioxidant status, immune responses gilthead seabream ( Sparus aurata ). Following established conditions, two FPHs were prepared from enzymatic hydrolysis discards whole‐body blue whiting Micromesistius poutassou ) gurnard heads Trigla...
Stressful husbandry conditions are likely to affect growth and amino acid metabolism in fish. In this study, chronic ammonia exposure was used test the effects of a stressor on Senegalese sole juveniles. The fish were exposed for 52 days 11.6 mg L−1 [low-TAN (L-TAN)] or 23.2 [high-TAN (H-TAN)] total nitrogen (TAN), 0 (Control). Growth L-TAN groups slightly but significantly different from Control [relative rate (RGR=0.35±0.13 0.52±0.23% day−1 respectively)]. H-TAN groups, severely affected...
To support the expected increase in aquaculture production during next years, a wider range of alternative ingredients to fishmeal is needed, towards contributing an sustainability. This study aimed test diets formulated with non-conventional feed on gilthead seabream (Sparus aurata) growth performance, utilization, apparent digestibility nutrients and nutrient outputs environment. Four isonitrogenous isoenergetic were formulated: control diet (CTRL) similar commercial three experimental...
Abstract The effect of two anesthetics, 2‐phenoxyethanol (2‐ PE ) and clove oil ( COil were studied in meagre, Argyrosomus regius . This study aimed to determine the adequate dose anesthesia for different aquaculture procedures, assess a sedative or stressor low anesthetic concentrations, doses at high fish densities longer periods time on survival behavior. Anesthetics tested concentrations: 2‐ 100, 250, 400, 550, 700 mg/L; 25, 40, 55, 70, 85 mg/L. Meagre became anesthetized within 10 min...
