-This study was carried out to evaluate the influence of different levels of digestible energy and digestible protein in diets of Nile tilapia (Oreochromis niloticus) broodstock on offspring growth during sex reversal stage. A total of 2,700 post-larvae (8.2±0.001 mg) derived from breeders fed nine diets with distinct levels of digestible protein (28, 34 and 40% DP) and digestible energy (2,800; 3,400; and 4,000 kcal DE.kg -1 ) were stored in twenty-seven 70 L tanks. After 30 days of growth, their average final weight (AFW, g), average weight gain (AWG, g), final standard length (SL, cm), condition factor (CF), specific growth rate (SGR, %/day), stock uniformity (UNI, %), survival (SUR, %) and sex reversal rate (SRR, %) were measured. Although female nutrition is thought to influence the performance or quality of progeny during early life stages, no influence of diets supplied to broodstock was detected on any parameter. Nonetheless, the offspring presented commercially satisfactory growth rates. Thus, diets containing 28% of digestible protein and 2,800 kcal of digestible energy.kg of diet -1 can be used to feed Nile tilapia broodstock without jeopardizing offspring performance during the sex reversal phase.

“…Sole Solea senegalensis (Kaup, 1858) broodstock, while fed through demand feeders for 16 months, regulated ARA intake to approximately 3% of total fatty acids in the diet (Norambuena et al, 2012). Likewise, the female catfish, Ictalurus punctatus (Rafinesque, 1818), fed different lipid sources showed high ARA values (5.4 to 9.0%) in their oocytes (Sink & Lochmann, 2008).…”

Characterization of the ovary fatty acids composition of Rhamdia quelen (Quoy & Gaimard) (Teleostei: Siluriformes), throughout their reproductive cycle

Knowledge about gonad fatty acid composition is important for broodstock diet formulation. This study characterized ovary fatty acid composition of wild female jundiá catfish (Rhamdia quelen) in their different gonadal maturation stages. Female jundiá (n = 36, average weight= 383.8 + 208.8 g) were captured in the rio Uruguay, comprising all seasons. Ovaries were extracted and classified according to their gonadal maturation stage. Gonad-somatic ratio varied significantly among seasons, being higher in spring (3.7), followed by summer (2.2), winter (0.9) and autumn (0.6). Main fatty acids groups detected were: saturated (SFA= 35.5%), monounsaturated (MUFA= 28.1%) and polyunsaturated fatty acids (PUFA= 33.5%). Over the four seasons, palmitic acid was recorded in large quantities, followed by docosahexaenoic acid (DHA) and arachidonic acid (ARA). ARA was present in higher concentrations in immature or maturing ovaries, and its content decreased along the maturation process. Conversely, DHA and eicosapentaenoic acid (EPA) contents increased during maturation. Such variation resulted in an increase in EPA/ARA and DHA/ARA ratios in mature gonads, which can be important for successful breeding. Such findings suggest that jundiá broodstock diets should contain lipids that provide long chain polyunsaturated fatty acids from both the n-3 and n-6 series to ensure gonadal maturation completion.O conhecimento da composição de ácidos graxos da gônada, como dos fatores que a influenciam são importantes na formulação de dietas para reprodutores de qualquer espécie. O presente estudo caracteriza a composição de ácidos graxos da gônada de fêmeas de jundiá (Rhamdia quelen) selvagens em seus diferentes estágios de maturação gonadal. Fêmeas de jundiá (n = 36) com peso médio de 383,8 + 208,8 g foram capturadas no alto rio Uruguai, ao longo de um ano, abrangendo as quatro estações. As gônadas foram extraídas, classificadas e posteriormente sua composição de ácidos graxos foi determinada. A relação gônado-somática variou significativamente entre as estações, sendo maior na primavera (3,7), seguida de verão (2,2), inverno (0,9) e no outono (0,6). Os principais grupos de ácidos graxos detectados foram: saturados (35,5 + 3,5%), monoinsaturados (28,1 + 4,3%) e ácidos graxos poli-insaturados (33,5 + 3,0%), com aproximadamente 30% para cada grupo. Ao longo das quatro estações, o ácido palmítico foi registrado em grandes quantidades, seguido do ácido docosahexaenóico (DHA) e ácido araquidônico (ARA). O ácido araquidônico estava presente em concentrações mais elevadas nas gônadas imaturas que nas gônadas maturas, e seu conteúdo diminuído ao longo do processo de maturação. Inversamente, o conteúdo de DHA e ácido eicosapentaenoico (EPA) aumentaram durante o processo de maturação. Tal variação resultou num aumento das relações EPA/ARA e DHA/ARA nas gônadas maturas, fato que pode ser importante para o sucesso da reprodução no jundiá. Tais resultados sugerem que dietas para reprodutores da espécie devem conter fontes de lipídios que proporcionem ác...

“…Following a crowding stress challenge, golden shiners exhibit a classical cortisol response, but magnitude and timecourse of this response was similar among fish raised on poultry fat or menhaden fish oil-based feeds [67] . Similarly, replacing dietary menhaden fish oil with poultry fat had no effect on reproductive performance of channel catfish [68] . Atlantic salmon fed a lard-based diet had a small but significant effect on circulating levels of astaxanthin, suggesting greater fillet pigmentation could be achieved by including lard in salmonid feeds [69] .…”

Problem statement:In the past, aquafeeds were comprised largely of fish meal and fish oil derived from marine reduction fisheries. In addition to being highly palatable and readily digested by cultured fishes, these feedstuffs were historically inexpensive sources of protein, energy and essential nutrients. However, increasing cost and concerns over safety and sustainability have greatly incentivized the transition from fish meal and oil to alternative sources of protein and lipid for aquafeed formulation. Fish oil replacement is proving more difficult than originally anticipated, particularly for marine carnivorous species. Approach: If complete fish oil replacement is not a viable goal for fish nutritionists and aquafeed manufacturers, at a minimum, we must strive for judicious use of limited marine-derived resources. In the present review, we explore the opportunities of using rendered fats as alternatives to marine-derived fish oils in aquaculture feeds, beginning with a discussion of the products themselves before reviewing the most recent literature and concluding with a discussion of the future of these products in aquafeed formulations. Results: Rendered fats have not been as intensively evaluated in aquaculture nutrition as grain and oilseed-derived lipids, although a number of recent publications on the subject suggest increasing interest in the use of rendered products in aquafeeds. Conclusion: Poultry fat, beef tallow, pork lard and to a lesser extent, yellow/restaurant grease and catfish oil, have been investigated individually or in combination with other lipids in feeds for a broad range of cultured taxa with generally acceptable results.
