“…In Macrobrachium culture, brooders are chosen for seed production not on the basis of size, but on the availability and ready to spawn. This results in selection of smallest brooders that in turn lead to a substantial reduction of mean size across generations and loss of performance (New, 1995). In the wild, M. rosenbergii female first mature at a size of 20-40 g; eggs obtained from these females are of good quality and their larvae show high percent of survival.…”

Fatty acid profiles of midgut gland (MG), ovary and eggs of Macrobrachium rosenbergii of wild and farm reared brooders indicate a significant variation of their components during the sexual maturation and spawning. In both groups, major fatty acids found in the chosen tissues were 14:0, 16:0, 18:0, 18:1n-9, 18:2n-6, 18:3n-3, 20:4n-6, 20:5n-3 and 22:6n-3. Of these, saturated fatty acids dominate over the monounsaturated (MUFA), polyunsaturated (PUFA) and highly unsaturated fatty acids (HUFA). Though all the four groups of fatty acids are found in both groups except n-3 HUFA (P>0.05) other categories are found in higher wild brooders (P<0.05). There was a significant difference in total weight, total length and clutch weight (P<0.05) between farm and wild brooders, but the gonadosomatic index (GSI) and midgut gland somatic index (MSI) did not vary significantly (P>0.05).

ABSTRACT. Eyestalk ablation in lhe prawn Macrobrachillm rosellbergii (De Man) (Cruslacea, Decapoda, Palaemonidae): effecls on reproduction, epidermic pigmenlation and feeding aclivity. This study analyze the consequences ofunilateral and bilateral ablation based on ovigerous percentage, consecutive spawns, and secondary effects ofthe surgical process in the lemales of Macl'obl'achium I'osenbel'gii (De Man , 1879). Two experiments were carried out with four and seven months old females in intelmolt stage. Each experiment was comprised ofconlrol, unilateral and bilateral ablation. Eyestalk ablation was done with a bistouly with a topic hot cauterization followed by application of antibiotic pomades. The animais were maintained at constant temperature (28 ± 1,05°C) and photoperiod of 12L:12D within fibercement boxes with sandy bottom and biological filter. Females were observed once a day during foulteen weeks, registering gonadal condition, ecdysis and presence of spermatophore (mating) and spawning. Unilateral ablation technique is more etlicient due to the anticipation ofthe first spawn, repeatability between spawns, expressive rate oI' ovigerous females and survival , that favored its applicability. Bilateral eyestalk ab lation produced the mortality 01' ali the females with change in coloration and food ac tivity patterns. These results corroborate other observations on penaeid shrimps, though bi lateral ablation on some lobsters was a success. These results showing an interespecitic variation and can be used in aquaculture projects. KEY WORDS . ClUstacea, eyestalk ablation, reproduction, pigmentation, feeding activity, prawn A obtenção de pós-larvas do camarão de água doce Macrobrachium rosenbergii (De Man, 1879) é limitada pela baixa disponibilidade de fêmeas ovígeras durante os meses de inverno em regiões de clima subtropical. Quando a temperatura da água dos viveiros é inferior a 18°C, os camarões apresentam uma diminuição do crescimento somático e da atividade reprodutiva, resultando, muitas vezes, em alta mortalidade. Após a água dos viveiros ganhar calor gradativamente, o cultivo pode ser reiniciado, embora, nesta ocasião, os criadores não possuam um número suficiente de pós-larvas para o povoamento; tal fato se deve à temperatura e fotoperíodo reduzidos, responsáveis pela minimização do processo reprodutivo na maioria dos crustáceos decápodosjá estudados (STEELE et aI.

“…The scampi is native to Southeast Asian countries and being cultured in Thailand, Vietnam, Kampuchea, Malaysia, Myanmar, Bangladesh, India, Sri Lanka, and the Philippines. It is also produced in Israel, Japan, Taiwan, and some African, Latin American, and Caribbean countries [10]. In the western hemisphere, examination of the possibility of intensive freshwater prawn culture began in the 1960s, but a considerable proportion of the global farmed freshwater prawn output still originates from the Indian sub-continent, Southeast Asia, and tropical areas of Latin America.…”

White Tail Disease of Freshwater Prawn, Macrobrachium rosenbergii

Macrobrachium rosenbergii is the most important cultured freshwater prawn in the world and it is now farmed on a large scale in many countries. Generally, freshwater prawn is considered to be tolerant to diseases but a disease of viral origin is responsible for severe mortalities in larval, post-larval and juvenile stages of prawn. This viral infection namely white tail disease (WTD) was reported in the island of Guadeloupe in 1995 and later in Martinique (FrenchWest Indies) in Taiwan, the People's Republic of China, India, Thailand, Australia and Malaysia. Two viruses, Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus-like particle (XSV) have been identified as causative agents of WTD. MrNV is a small icosahedral non-enveloped particle, 26-27 nm in diameter, identified in the cytoplasm of connective cells. XSV is also an icosahedral virus and 15 nm in diameter. Clinical signs observed in the infected animals include lethargy, opaqueness of the abdominal muscle, degeneration of the telson and uropods, and up to 100 % within 4 days. The available diagnostic methods to detect WTD include RT-PCR, dot-blot hybridization, in situ hybridization and ELISA. In experimental infection, these viruses caused 100 % mortality in post-larvae but failed to cause mortality in adult prawns. The reported hosts for these viruses include marine shrimp, Artemia and aquatic insects. Experiments were carried out to determine the possibility of vertical transmission of MrNV and XSV in M. rosenbergii. The results indicate that WTD may be transferred from infected brooders to their offspring during spawning. Replication of MrNV and XSV was investigated in apparently healthy C6/36 Aedes albopictus and SSN-1 cell lines. The results revealed that C6/36 and SSN-1cells were susceptible to these viruses. No work has been carried out on control and prevention of WTD and dsRNA against protein B2 produced RNAi that was able to functionally prevent and reduce mortality in WTD-infected redclaw crayfish.
