Abstract: ABSTRACT. Studies on the occurrence, temporal distribution and nychthemeral variation of Macrobrachium amazonicum (Heller, 1862) were undet1aken in Leopoldo's Inlet, upper Paraná River, Porto Rico, Paraná, Brazil. Seventeen thousand and sixty specimens (11,786 larvae and 5,274 juveniles) were captured with a conicalcylindrical plankton net of mesh 0.5mm in monthly samples between February 1991 and Februaty 1992. Results show lhat the greatest densities of larvae (301.83 larvae/I Om) andjuveniles (168.8/1 Om) … Show more

“…The autumn period corresponds the highest larvae abundances (χ 2 , p < 0.05). Bialetzki et al, (1997) cite for M. amazonicum the greatest captures in the spring and summer months (from September to December), in the hydrographic basin of the Paraná river, where the seasonality is more pronounced than in the present study area. Müller & Prazeres (1992) found, for M. olfersii, in Santa Catarina, reproduction periods that encompass the autumn and the beggining of the summer, this species presenting two reproduction periods per year.…”

“…A curvina, P. squamosissimus possui boca grande terminal (Bialetzki et al 2002) bastante protrátil o que possivelmente facilita a captura de presas em locais de difícil acesso para a maioria dos outros piscívoros. No presente estudo, a dieta dessa espécie foi a que mais diferiu dos outros predadores, pelo fato de curvinas imaturas, terem consumido uma proporção expressiva do camarão Macrobrachium amazonicum, um recurso muito abundante na planície de inundação (Bialetzki et al 1997). Os adultos dessa espécie consumiram preferencialmente peixes, possivelmente devido à relação custo/ benefício das presas ser melhor que itens menores, como camarões.…”

“…Among these species, the Amazon River prawn Macrobrachium amazonicum (Heller 1862) has remained relatively unknown, although its potential for aquaculture and fisheries is highly rated (Kutty et al 2000, Moraes-Valenti & Valenti 2007. It is widely distributed along the northern and northeastern coasts of South America (Holthuis 1952, Rodríguez 1982, Montoya 2003, and fully limnic inland populations live in the Amazon and Orinoco River basins (Walker 1992, Odinetz Collart & Rabelo 1996, as well as in the upper Parana and Paraguay systems (Pettovello 1996, Bialetzki et al 1997, Magalhães 2000, Hayd & Nakagaki 2002.…”

“…The occurrence of Macrobrachium amazonicum in the La Plata system has occasionally been considered to be the result of a recent anthropogenic introduction (Bialetzki et al 1997, citing a technical report by Torloni et al 1993). In a recent review, Maciel & Valenti (2009) also cited Magalhães et al (2005) in this context.…”

“…The South American species M. amazonicum (Heller 1862) shows a particularly wide geographic distribution, ranging from the Caribbean coast of Columbia (12°N) to northern Argentina and Paraguay (28°S), and from the subandine slopes of Ecuador, Peru, and Bolivia to the Atlantic coasts of northeastern Brazil, i.e. more than 4000 km across in both N-S and W-E directions (Holthuis 1952, Ramos-Porto & Coelho 1990, Odinetz Collart & Rabelo 1996, Pettovello 1996, Bialetzki et al 1997, Magalhães 2000.…”
