“…A combination of enriched ARA and LOA in diets may have facilitated the accumulations of other important fatty acids, especially DHA, in eggs and larvae despite the lower n-3 lcPUFA available in diets. Having adequate energy required by these energetically expensive life stages, especially from fertilized eggs (containing mainly yolk) to advanced embryo and larvae (involving organ formation) (Habashy, Sharshar & Hassan, 2012; Yao et al, 2006) may allow for efficient utilization of n3-PUFA, especially DHA, required for tissue and organ formation in embryos and larvae. Larvae will continue to rely on yolk for nutrients during the first larval stage, after which they will need an external food source (Anger, 2001).…”

“…The dominance of these fatty acid classes in muscle, ovarian and egg tissues were similar to those observed in wild and farmed M. rosenbergii (wild prawn: Cavalli et al, 2001 (muscle, ovaries and egg); farmed prawn: Balamurugan, Mariappan & Balasundaram, 2015 (ovaries and egg), Li, Sinclair & Li, 2011 (muscle), Bragagnolo & Rodriguez-Amaya, 2001 (muscle), Cavalli, Lavens & Sorgeloos, 1999 (muscle, ovaries and egg), Chanmugam et al, 1983 (muscle)) and other marine shrimp species ( P. monodon, Huang et al, 2008) (ovaries and egg, farmed shrimp), (O’Leary & Matthews, 1990) (muscle, wild and farmed shrimp); P. chinensis , Ji & Xu, 1992; L. vannamei , Wouter et al, 2001; other wild shrimp species, Li, Sinclair & Li, 2011) although ovarian tissue of farmed M. rosenbergii analyzed in this and other studies tended to contain higher proportions of these fatty acid classes compared to those of marine shrimp. These classes of fatty acids usually serve as a main source of energy for growth (Wehrtmann & Graeve, 1998), ovarian development (Harrison, 1990), embryogenesis (Clarke, Brown & Holmes, 1990; Yao et al, 2006) and early larval development (Roustaian et al, 1999; Yao et al, 2006) as they are typically preferred substrates for b-oxidation reactions (Henderson, 1996). …”

The giant river prawn (Macrobrachium rosenbergii) is one of the most farmed freshwater crustaceans in the world. Its global production has been stalling in the past decade due to the inconsistent quality of broodstock and hatchery-produced seeds. A better understanding of the role of nutrition in maturation diets will help overcome some of the production challenges. Arachidonic acid (20:4 n-6, ARA) is a fatty acid precursor of signaling molecules important for crustacean reproduction, prostaglandins E and F of the series II (PGE2 and PGF2α), and is often lacking in maturation diets of shrimp and prawns. We examined the effects of ARA in a combination of different fish oil (FO) and soybean oil (SO) blends on females’ reproductive performance and larval quality. Adult females (15.22 ± 0.13 g and 11.12 ± 0.09 cm) were fed six isonitrogenous and isolipidic diets containing one of two different base compositions (A or B), supplemented with one of three levels of Mortierella alpine-derived ARA (containing 40% active ARA): 0, 1 or 2% by ingredient weight. The two base diets differed in the percentages of (FO and SO with diet A containing 2% SO and 2% FO and diet B containing 2.5% SO and 1.5% FO, resulting in differences in proportional contents of dietary linoleic acid (18:2n-6, LOA) and docosahexaenoic acid (22:6n-3, DHA)). After the eight-week experiment, prawns fed diet B with 1 and 2% ARA supplement (B1 and B2) exhibited the highest gonadosomatic index (GSI), hepatosomatic index (HSI), egg clutch weight, fecundity, hatching rate, number of larvae, and reproductive effort compared to those fed other diets (p ≤ 0.05). Larvae from these two dietary treatments also had higher tolerance to low salinity (2 ppt). The maturation period was not significantly different among most treatments (p ≥ 0.05). ARA supplementation, regardless of the base diet, significantly improved GSI, HSI, egg clutch weight and fecundity. However, the diets with an enhanced ARA and LOA (B1 and B2) resulted in the best reproductive performance, egg hatchability and larval tolerance to low salinity. These dietary treatments also allow for effective accumulation of ARA and an n-3 lcPUFA, DHA in eggs and larvae.

“…It should however be noted that the total metabolic cost most likely is higher, since neither lipids nor carbohydrates were quantified in the present study. In other crustaceans, such as European lobster Homarus gammarus and the prawn Macrobrachium rosenbergii, lipids are important energy substrates (Rosa et al 2005, Yao et al 2006. It is not known at present if salmon lice can actively absorb organic matter from seawater, as can many other marine invertebrates (Manahan et al 1982), but any such uptake would also contribute to the energy budget.…”

The salmon louse Lepeophtheirus salmonis Krøyer affects a variety of wild salmonoid hosts, but is also an important pest in aquaculture, which is a globally important and rapidly growing industry. Salmon lice have large reproductive outputs, and knowledge of reproductive processes may be crucial for the control of this parasite. Here, we report on the characterisation of 2 vitellogenins (LsVit1 and LsVit2), which are the precursors of salmon-louse egg-yolk glycoprotein. The structure of LsVit1 and LsVit2 was examined and compared to that in other oviparous animals. Phylogenetic analysis of LsVit1 and LsVit2 confirmed the view that crustaceans are a polyphyletic group. Transcriptional and translational analysis demonstrated production of LsVit1 and LsVit2 in the subcuticular tissue of the adult female lice. LsVit1 and LsVit2 could also be found in maturing oocytes and developing embryos and early larval stages. LsVit2 was found to be processed into 2 smaller fragments, whereas LsVit1 was found to be full length when deposited into the oocytes. Degradation of LsVit1 and LsVit2 was characterised through embryogenesis and the early non-feeding larval stages. Finally, protein content and the level of free amino acids were analysed in embryos and larval stages and their role in nutrition and osmoregulation discussed. In conclusion, our results confirm the role of vitellogenins in reproduction as providers of embryonic and larval nutrition.

“…This egg growth pattern is common in Malacostracans (Müller et al, 2004;Sudhakar et al, 2014). It is associated with an increase in the water content of the egg (Yao et al, 2006;Habashy et al, 2012), and with an increase in the size of the developing embryo (Anderson, 1982;Lourdes and Cuvin-Aralar, 2014).…”

The freshwater prawn Macrobrachium jelskii (Miers, 1877) is widely distributed in South America's lentic and lotic habitats. We studied the population structure and reproductive biology of the species in the municipality of Cruz das Almas, state of Bahia, Brazil, to supply information on this ecologically and economically relevant species. Samples were collected monthly, from February 2013 to January 2014, at Laranjeiras pond. The sex ratio was biased towards females (1.4 females : 1 male). The mean carapace length of females and males was respectively 8.08 ± 1.37 mm and 6.61 ± 1.11 mm. Ovigerous females comprised 22.5% of all sampled females, and their reproductive activity, characterized as seasonal-continuous, was positively correlated with precipitation. The average size of females at the onset of functional maturity was estimated at 6.67 mm CL and the mean fecundity was 25.2 ± 8.9 eggs. Egg size, mass and volume increased significantly during embryonic development. Our data strongly indicate that the reproductive strategy that best fits the species is the "pure search" mating system.
