“…Selon Dumont et al (2007), la taille atteinte à la première maturité sexuelle correspond à la taille des crevettes au moment de la maturation des gonades. L'étude de la gamétogenèse chez M. vollenhovenii a montré, selon les coupes histologiques réalisées par Olele et al (2012) (Figure 8 et 9 Owolabi, 2012). Les reproducteurs mâles deviennent dominants territoriaux avec de grosses pinces, tandis que les femelles pour la plupart sont grainées.…”

REMERCIEMENTS Les auteurs remercient Responsables du Projet de Productivité Agricole en Afrique de l'Ouest (PPAAO) du Programme Cadre d'Appui à la Diversification Agricole (ProCAD) au Bénin pour avoir financé ces travaux. RESUMEL'objectif principal de cette étude est de faire le point des connaissances sur quelques aspects de la morphologie, de la biologie de reproduction et des besoins alimentaires en élevage de M. vollenhovenii afin d'entreprendre son élevage en captivité. L'approche méthodologique utilisée est basée sur la recherche documentaire et a consisté à l'analyse des publications scientifiques, des thèses et livres portant sur la crevette d'eau douce Macrobrachium en général et de Macrobrachium vollenhovenii en particulier. Les larves vivent exclusivement en eau saumâtre. La nutrition larvaire est basée sur le plancton tandis que les adultes sont omnivores à dominance carnivore. La croissance se fait par des mues donnant une population à structure hétérogène. Une femelle mesurant 11,40 cm de taille peut pondre jusqu'à 56481 oeufs. La gamétogenèse comporte 5 phases : phase dominante des cellules immatures, phase d'évolution des cellules immatures, phase dominante des cellules mûres, phase des cellules mûres et phase d'émission des gamètes. Les oeufs, au bout de deux à trois semaines, donnent à l'éclosion de petites larves appelées nauplius qui évolue en zoé et mysis. Biology and breeding prospect of giant fresh water shrimp Macrobrachium vollenhovenii (Herklots, 1857) ABSTRACTThe main target of this study is to give the point of knowledge on some aspects of morphology, on reproduction biology and food needs of M. vollenhovenii in breeding in order to undertake his breeding in captivity. The methodological approach used is based on desk research and consisted in the analysis of L. GANGBE et al. / Int. J. Biol. Chem. Sci. 10(2): 573-598, 2016 574 scientific publications, theses and books on the species of freshwater shrimp Macrobrachium genre in general and in particular Macrobrachium vollenhovenii. The larvae live exclusively out of brackish water. The larval nutrition is based on the plankton while adults are omnivorous with carnivorous predominance. The growth is done by moults giving a population to heterogeneous structure. A female measuring 11.40 cm of size can lay up to 56,481 eggs. The gametogenesis is made up of 5 stages: immature cells dominant stage, immature cells evolution stage, ripe cells dominant stage, ripe cells and gametes issuance stage. Eggs, after two to three weeks, give the hatch small larvae called nauplius that evolves zoe and mysis. After 15 larval stages, metamorphosis occurs between the 17 th and 28 th day to provide post-larvae witch are small replicas in miniature adults.

“…Indeed, M. vollenhovenii prawns were successful in controlling schistosome-susceptible snail populations under laboratory conditions [25]. Like other freshwater prawns, M. vollenhovenii exhibits clear sexual dimorphism, with males achieving larger maximum size than females [30]–[32]. Sexual dimorphism in many crustaceans is mediated by secretions of the androgenic gland (AG), a masculinizing endocrine organ unique to this sub-phylum [33]–[36].…”

“…We also conducted retrospective interviews with fishermen regarding the abundance of prawns along the Senegal River basin before and after construction of the Diama Dam. Studies of prawn catches and earlier literature on male superior size [31], [32] suggested that both prawn fisheries and their biological control functions could benefit from restocking with all-male populations. A further objective of this study was thus to lay the required molecular foundation for the production of all-male populations.…”

The Prawn Macrobrachium vollenhovenii in the Senegal River Basin: Towards Sustainable Restocking of All-Male Populations for Biological Control of Schistosomiasis

et al. 2014

Early malacological literature suggests that the outbreak of schistosomiasis, a parasitic disease transmitted by aquatic snails, in the Senegal River basin occurred due to ecological changes resulting from the construction of the Diama dam. The common treatment, the drug praziquantel, does not protect from the high risk of re-infection due to human contact with infested water on a daily basis. The construction of the dam interfered with the life cycle of the prawn Macrobrachium vollenhovenii by blocking its access to breeding grounds in the estuary. These prawns were demonstrated to be potential biological control agents, being effective predators of Schistosoma-susceptible snails. Here, we propose a responsible restocking strategy using all-male prawn populations which could provide sustainable disease control. Male prawns reach a larger size and have a lower tendency to migrate than females. We, therefore, expect that periodic restocking of all-male juveniles will decrease the prevalence of schistosomiasis and increase villagers' welfare. In this interdisciplinary study, we examined current prawn abundance along the river basin, complemented with a retrospective questionnaire completed by local fishermen. We revealed the current absence of prawns upriver and thus demonstrated the need for restocking. Since male prawns are suggested to be preferable for bio-control, we laid the molecular foundation for production of all-male M. vollenhovenii through a complete sequencing of the insulin-like androgenic gland-encoding gene (IAG), which is responsible for sexual differentiation in crustaceans. We also conducted bioinformatics and immunohistochemistry analyses to demonstrate the similarity of this sequence to the IAG of another Macrobrachium species in which neo-females are produced and their progeny are 100% males. At least 100 million people at risk of schistosomiasis are residents of areas that experienced water management manipulations. Our suggested non-breeding sustainable model of control—if proven successful—could prevent re-infections and thus prove useful throughout the world.
