“…The highest amount of PUFA was noticed in gonads of resting Almaco jack (14.96%). Still, our results are much lower when compared to published results for the for S. dumerili (Rodríguez-Barreto et al, 2012;Öksüz, 2012). Differences found between studies were mainly due to the lower DHA and EPA content found in the present study, which may be related to fish age and nutritional status.…”

“…Overall, females at prespawning stage presented higher lipid content in all sampled tissues, with a marked increase in dorsal muscle. Dorsal muscle lipid content was higher in our samples (24.04%) when compared to the results found in the muscle of S. fasciata at the same maturation stage (Nogueira et al, 2016) and of S. dumerilli (Haouas, Zayene, Guerbej, Hammami, & Achour, 2010;Rodríguez-Barreto et al, 2012), but similar to those found by Rodríguez-Barreto et al (2014) in indoor cultivated S. dumerilli. Such differences highlight the need of knowing fish nutritional value, especially when fish are not easy to distinguish, as is the case between Almaco jack adults and greater amberjack juveniles.…”

Almaco jack (Seriola rivoliana) is an emergent marine finfish that presents high market value. In order to study the feasibility of the exploitation of this marine resource for human consumption the evaluation of the nutritional characteristics of this species has attracted the attention of the scientific community. The lipid characteristics and fatty acid composition were evaluated in muscle, liver and gonad tissues of wild Almaco jack from Atlantic Ocean at two different maturation stages. According to results, the lipid content was found higher at pre-spawning stage (21.78 -36.17%) and highest proportion being exhibited in the liver. Palmitic acid was predominant among the saturated fatty acids (35.42 -47.80%) and oleic acid was detected as the main monounsaturated acid (25.26 -36.55%). Higher amounts of ω3 polyunsaturated fatty acids (PUFAs) were identified in gonads of resting females, of which more than 84% was accounted by docosahexaenoic acid (12.62%). Muscle and liver of resting females presented the highest ω3/ω6 ratios. The Hypocholesterolemic/Hypercholesterolemic index was higher in gonads of both maturation stages (0.97 and 1.05). The results showed that wild Almaco jack at resting stage were a better source of oleic acid and ω3 PUFAs and that liver and gonads present good nutritional by-products.

“…Thus, their relative proportion in the tissue is crucial for successful reproduction. An imbalance in EPA/ARA ratio can deregulate the production of lipid mediators involved in the reproduction (Rodriguez-Barreto et al, 2012). ARA and EPA as well as the other n-3 LC-PUFA appear to be involved at different ovarian maturation stages, leading to the need to include lipid sources containing the two series of fatty acids in the diet of jundiá broodstock.…”

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...

“…However, such beliefs are unsubstantiated with largely no underlying scientific knowledge by the public. A number of studies have outlined various differences in organoleptic values and nutritional composition between farmed and wild fish, where more often than not cultured fish are deemed of lesser quality (Cahu et al, 2004;Fuentes et al, 2010;Krajnović-Ozretić et al, 1994;Rodríguez-Barreto et al, 2012;Zhao et al, 2010). However, this is not unequivocally the case and some research has outlined contrasting and/or comparable qualities (nutritional and sensory) in farmed and wild fish Mnari et al, 2007).…”
