“…LC-PUFA are important in membrane formation and proper function (Sargent et al, 2002). The n-3/n-6 ratio in jundiá ovary increased in more advanced maturation stages and the same pattern was observed for the crustacean Marsupenaeus japonicus (Spence Bate, 1888) captured in a natural environment (Tahara & Yano, 2004). In turn, the UFA/SFA ratio in membrane phospholipids is influenced by temperature, this being a crucial factor in determining the degree of fluidity (Hazel et al, 1991;Bowden et al, 1996;Miller et al, 2006).…”

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...

“…Both groups reported that PGs controlled ovarian growth of the crab, crayfish and the freshwater shrimp Macrobrachium rosenbergii. On the contrary, there was no correlation of GSI with PGE 2 and PGF 2a in Marsupenaeus japonicus [16,30,31]. The concentration of PGF 2a and PGE 2 in haemolymph was high in previtellogenic stage ovaries and gradually decreased toward maturation.…”

Prostaglandins are involved in the reproductive processes in a variety of animals, including crustaceans. It was found that polychaetes, the best maturation diet for shrimp broodstock, possessed the greatest variation of prostaglandin E 2 (PGE 2 ) when compared with other live feeds. The level of PGE 2 varied according to sizes, feed intake, sources and type of polychaete. The matured and also larger sand polychaete Perinereis sp. contained higher PGE 2 levels than younger and smaller sand polychaetes (18.16 ± 5.82 ng PGE 2 mg -1 protein for polychaetes at an average length of 10 cm up to 160.8 ± 37.09 ng PGE 2 mg -1 protein for polychaetes at an average length of 17 cm). The PGE 2 levels in ovaries and haemolymph of female shrimp fluctuated with the developmental stage of the ovaries. The highest concentration of PGE 2 in haemolymph was at stage 3 of ovarian development, whereas the highest concentration of PGE 2 in shrimp ovaries was at stage 4. In vitro incubation of Penaeus monodon pre-vitellogenic oocytes with polychaete extract and synthetic PGE 2 demonstrated that both PGE 2 s enhanced oocyte development, especially during late development and ovulation. The putative role of PGE 2 from polychaetes or the presence of PGE 2 in polychaetes may be a factor in their role as a dietary constituent required for shrimp oocyte development.

“…The presence of AA has been also identified in different crustaceans such as kuruma prawns, Penaeus japonicus and Marsupenaeus japonicus [3,4], green tiger prawn Penaeus semisulcatus [5], shrimps Penaeus monodon [6,7], Litopenaeus vannamei [8] and Penaeus merguiensis [9]. Furthermore, the presence of prostaglandins PGE 2 and PGF 2α were reported in Procambarus paeninsulanus [10], Marsupenaeus japonicus [4] and Penaeus monodon [11], whereas, only PGE 2 was reported in Carcinus maenas [12]. Along with PGE 2, and PGF 2α , PGD 2 also has been identified in the rice field crab Oziothelphusa senex senex [13].…”
