“…The key event in the oocyte development is the process of yolk synthesis or vitellogenesis (Tsukimura, 2001; Okuno et al, 2002; Nagaraju, 2011; Revathi et al, 2012; Reddy et al, 2013). Vitellogenesis in M. rosenbergii begins with the synthesis of vitellogenin in the hepatopancreas, then it is released into the hemolymph and cleaved into vitellin, which is taken up and incorporated into the yolk granules in the late oocytes, i.e., Oc3 and Oc4 (Okuno et al, 2002).…”

Starvation Promotes Autophagy-Associated Maturation of the Ovary in the Giant Freshwater Prawn, Macrobrachium rosenbergii

Limitation of food availability (starvation) is known to influence the reproductive ability of animals. Autophagy is a lysosomal driven degradation process that protects the cell under metabolic stress conditions, such as during nutrient shortage. Whether, and how starvation-induced autophagy impacts on the maturation and function of reproductive organs in animals are still open questions. In this study, we have investigated the effects of starvation on histological and cellular changes that may be associated with autophagy in the ovary of the giant freshwater prawn, Macrobachium rosenbergii. To this end, the female prawns were daily fed (controls) or unfed (starvation condition) for up to 12 days, and the ovary tissue was analyzed at different time-points. Starvation triggered ovarian maturation, and concomitantly increased the expression of autophagy markers in vitellogenic oocytes. The immunoreactivities for autophagy markers, including Beclin1, LC3-II, and Lamp1, were enhanced in the late oocytes within the mature ovaries, especially at the vitellogenic stages. These markers co-localized with vitellin in the yolk granules within the oocytes, suggesting that autophagy induced by starvation could drive vitellin utilization, thus promoting ovarian maturation.

“…This pattern has often been attributed to the occurrence of hermaphroditism in caridean shrimps (Wenner, 1972;Bauer, 2000;2004;Correa and Thiel, 2003). However, several studies focusing on histology and gonadal development found no evidence of hermaphroditism in species of Macrobrachium (Carvalho and Pereira, 1981;Damrongphol et al, 1991;Chaves and Magalhães, 1993;Mossolin and Bueno, 2002;Silva et al, 2009;Revathi et al, 2012). By ruling out hermaphroditism, variations in the sex ratio of populations of Macrobrachium spp.…”

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.

“…Maturation stages of the ovary were classified into one of five stages, based on the ovarian size and color observed through the carapace, following the criteria detailed in Damrongphol, Eangchuan & Poolsanguan (1991), Chang & Shih (1995) and Revathi et al (2012) (Fig. 1).…”

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.
