Ostreopsis cf. ovata and Ostreopsis lenticularis (Dinophyceae: Gonyaulacales) in the Galapagos Marine Reserve
(Scientia Marina, 2020-06-15) Aigües Marines i Continentals; Aqüicultura
The genus of benthic dinoflagellates Ostreopsis is of particular interest because some species negatively impact human health and coastal marine ecosystems. Ostreopsis populations from a remote area, ...
Assessing the economic impact of key operational factors on grow-out farms producing European sea bass under different scenarios of production
(Aquaculture Economics and Management, 2021-11-05) Aqüicultura
The aim of this work is to evaluate how changes in a set of different key operational factors (e.g., the unit sales price, the fingerling unit cost, the feed unit cost, and so on) would impact on the ...
Advantages of using economic weights in animal production
(Veterinaria y Zootecnía, 2018-12-26) Genètica i Millora Animal
Introduction: The economic evaluation of the
production systems can be performed using the gain function technique. Objective:To
carry out a review of the literature on the use of the profit function ...
The ontogeny of greater amberjack digestive and antioxidant defence systems under different rearing conditions: A histological and enzymatic approach
(Aquaculture Nutrition, 2020-09-23) Aqüicultura
An overall synchronization of morphological and physiological ontogenetic events of the digestive and antioxidant defence systems occurred in greater amberjack (Seriola dumerili) larvae reared under ...
Fermentation of Soybean Meal with Lactobacillus acidophilus Allows Greater Inclusion of Vegetable Protein in the Diet and Can Reduce Vibrionacea in the Intestine of the South American Catfish (Rhamdia quelen)
(Animals, 2022-03-09) Aqüicultura
The objective of this study was to evaluate the effect of diets containing different inclusion levels (0%, 7%, 14%, 21% and 28%) of soybean meal fermented by Lactobacillus acidophilus (SMFL) on the ...
Molecular and Functional Characterization of Elovl4 Genes in Sparus aurata and Solea senegalensis Pointing to a Critical Role in Very Long-Chain (>C24) Fatty Acid Synthesis during Early Neural Development of Fish
(International Journal of Molecular Sciences, 2020-05-15) Aqüicultura
Very long-chain fatty acids (VLC-FA) play critical roles in neural tissues during the early development of vertebrates. However, studies on VLC-FA in fish are scarce. The biosynthesis of VLC-FA is ...
Different Fish Meal and Fish Oil Dietary Levels in European Sea Bass: Welfare Implications After Acute Confinement Stress
(Frontiers in Marine Science, 2022-01-04) Aqüicultura
To provide practical feeding management guidelines preceding a stressful episode during farming practices, European sea bass juveniles (initial weight: 72.3 g) were fed for 60-days different fish meal ...
Physiological processes modulate acute and chronic responses to dietary protein/energy ratio fluctuations in individuals and families of Manila clam (Ruditapes philippinarum) selected for variable growth rates
(Aquaculture, 2020-01-31) Aqüicultura
A range of phenotypes differing in growth rate were designed in the Manila clam by combining separate breeding families with size segregation within each family to constitute fast and slow growing groups. ...
Impact of dietary porcine blood by-products in meagre (Argyrosomus regius) physiology, evaluated by welfare biomarkers and the antibacterial properties of the skin mucus
(Fish & Shellfish Immunology, 2021-09-14) Aqüicultura
Tools are required for quick and easy preliminary evaluation of functional feeds efficiency on fisheries. The analysis of skin mucus biomarkers is a recent alternative approach providing a faster feed-back ...
Linkage mapping, comparative genome analysis, and QTL detection for growth in a non-model teleost, the meagre Argyrosomus regius, using ddRAD sequencing
(Scientific Reports, 2022-03-29) Aqüicultura
Meagre (Argyrosomus regius), is a benthopelagic species rapidly emerging in aquaculture, due to its low food to biomass conversion rate, good fillet yield and ease of production. Tracing a species genomic ...
