“…Water quality parameters like temperature, pH, dissolved oxygen, alkalinity, ammonia-nitrogen, and nitrate-nitrogen during growth trial period were found within acceptable range for freshwater prawn rearing (Correia et al, 2000;New, 2002;Mallasen et al, 2003) Table 3. Though survival of M. rosenbergii was higher in freshwater (0 ppt) in the study, the highest growth was achieved in 10 ppt.…”

a b s t r a c tTwo independent experiments were performed to determine the effects of salinity on survival and growth of juvenile Macrobrachium rosenbergii, first one was to determine the median lethal salinity (MLS-50 96 h ) and second one was to assess the survival and growth at different sub-lethal salinities under field condition. In MLS-50 96 h study 0, 5, 10, 15, 20, 25 and 30 ppt salinities were used to initially find out the salinity tolerance range. Accordingly, a definitive salinity tolerance test was done in next phase to find out exact median lethal salinity by directly transferring the test species to 21, 22, 23, 24, 25, 26 and 27 ppt salinity for 96 h. The median lethal salinity of M. rosenbergii was estimated at 24.6 ppt. In the second experiment, survival and growth performances of the prawn were recorded at different sub-lethal salinities viz., 5, 10, 15 and 20 ppt along with 0 ppt as control during 60 days culture period. The prawn exhibited lowest final average weight at 20 ppt salinity and significantly highest at 10 ppt salinity. Highest SGR and weight gain were obtained at 10 ppt followed by 5 ppt, 15 ppt and 0 ppt salinity but differences among treatment were not significant (P > 0.05). Survival rate of prawn varied between 91% (at 0 ppt) and 78% (at 20 ppt). The prawn grew and survived satisfactorily at 0-15 ppt salinities, implying that the species can be cultured commercially at wide salinity range. M. rosenbergii can be considered as an ideal species to promote, in view of current and future climate variables as more and more coastal areas of India are going to be vulnerable to saline water inundation.

“…). The levels of ammonia and nitrite remained below the lethal concentration, 0.5 and 0.1 mg L −1 , respectively (Mallasen & Valenti , ). This suggests that recirculating systems provided with large crushed mollusc shell biofilters (~25% the volume of the rearing hatchery tank) may support an intensification of at least 140 larvae L −1 without affecting water quality.…”

We evaluated the effect of intensification on Macrobrachium rosenbergii hatchery in clear water recirculating system. Larvae were raised in 120-L cylindrical tanks coupled with 30-L biofilters. We performed two experiments in randomized blocks.In the first, we tested the stocking densities of 50, 70 and 90 newly hatched larvae L À1 . Survival did not differ by ANOVA (P = 0.343), but productivity increased with the intensification (P = 0.038). In the second experiment, we tested the stocking densities of 80, 100, 120 and 140 newly hatched larvae L À1 . Survival decreased (P = 0.039) as density increased, but productivity did not differ (P = 0.317). The period of culture ranged from 22 to 23 days. The intensification did not influence water quality parameters or larval development. Survival decreased with the intensification and the space showed to be a limiting factor on tanks stocked with 90 larvae L À1 or more. Productivity curve shows an increase from 50 to 100 larvae L À1 and tended to reach plateau on stocking densities higher than 100 larvae L À1 . In addition, the intensification improved the use of Artemia cysts by decreasing the superfluous feeding. Thus, we recommend stocking of 80 to 100 newly hatched larvae L À1 as the best option for M. rosenbergii hatchery in clear water recirculating system.

“…Montoya (2003) studied the species M. amazonicum, M. surinamicum and M. jelskii in the delta of the Orinoco River (Venezuela) associated with water-hyacinths (floating aquatic vegetation Eichhornia crassipes (Martius) Solms) and found that where the amount of dissolved oxygen was lower, the greater was the participation of M. amazonicum and M. surinamicum in the local fauna composition. Similarly, Malassen and Valenti (2006) studied the effects of amount of nitrite in larval development of M. rosenbergii and concluded that probably, under high concentrations of this chemical compound, the species uses energy to adjust its physiological mechanisms against the toxic effects of nitrite, even reducing weight gain or decreasing the number of metamorphoses. Eventually, this strategy might be common to Macrobrachium species; however, this statement needs to be investigated.…”

Macrobrachium surinamicum is a small shrimp that inhabits rivers of low salinity. It is mainly caught as bycatch in Amazon shrimp Macrobrachium amazonicum fisheries, which is widely exploited by artisanal fisheries for food and economic needs of the riverside population. This study aimed to characterize the spatial and temporal distribution of the freshwater shrimp M. surinamicum in the Guajará Bay and on Mosqueiro Island, correlating the abundance of this species with abiotic factors (temperature and salinity). ResumoMacrobrachium surinamicum é um camarão de pequeno porte que habita a foz de rios e águas de baixa salinidade. Sua captura na Amazônia ocorre principalmente como fauna associada à pesca do camarão-da-Amazônia Macrobrachium amazonicum que é largamente explorado pela pesca artesanal atendendo as necessidades alimentícias e econômicas da comunidade ribeirinha. O presente estudo teve como objetivo caracterizar a distribuição espaço-temporal do camarão dulcícola M. surinamicum na Baía do Guajará e Ilha de Mosqueiro, correlacionando a abundância desta espécie com fatores abióticos (temperatura e salinidade). Os exemplares foram capturados no período de maio/06 a abril/07 em seis locais: Ilha de Mosqueiro (Furo das Marinhas e Porto do Pelé), Distrito de Icoaraci, Ilha do Arapiranga, orla de Belém e Ilha do Combu com armadilhas (matapis). Um total de 361 camarões foi capturado, sendo a maior abundância em dezembro e a menor em julho de 2006. A maior captura foi na Ilha de Arapiranga e a menor na Ilha de Mosqueiro. A abundância diferiu significativamente em dezembro/06 e nenhuma variável estudada teve influência significativa na abundância de M. surinamicum. A Baía do Guajará, especialmente os locais mais abrigados como a Ilha de Arapiranga e do Combu, propiciam o desenvolvimento de M. surinamicum, o que indica que esta espécie tenha preferência para áreas menos antropizadas.Palavras-chave: Crustacea, Decapoda, ecologia, camarão dulcícola.
