Abstract:
The karyotype of Semaprochilodus insignis and Semaprochilodus taeniurus were analyzed through the conventional Giemsa staining, C-banding, and the nucleolar organizer regions. The diploid number is the same (2n = 54) in both species, but S. taeniurus shows a chromosomic system of the ZZ/ZW type. This and some other differences between the two karyotypes will be useful in further studies on the possible hybrid origin of the "jaraqui açú," a low frequency form that is observed together with S. insignis and S. taeniurus. Key words: fish, ZZ/ZW system, constitutive heterochromatin, nucleolar organ

Abstract:
A myxosporean infecting the gill filaments of the freshwater teleost Semaprochilodus insignis collected in the TrombetasRiver (Central Amazonian Region, Brazil) is described using light and electron microscopy. The spores were ovoid infrontal view with round extremities and measured 15.4 ± 0.6μm in total length, 12.4 ± 0.5μm wide and 8.1 ± 0.7μmthick; the spore valves (up to 0.4μm) were surrounded by an uniform dense layer with variable thickness up to ~1.0μm)due to the presence of a complex network of anastomosed microfibrils closely adherent to the valves.

O objetivo deste trabalho foi avaliar o desempenho de tambaqui (Colossoma macropomum), em policultivo com jaraqui (Semaprochilodus insignis), alimentado com produtos agrícolas e florestais como suplemento. Dois viveiros, medindo 644 m² (Viveiro A, consorciado com suínos) e 1.075 m² (Viveiro B, não-consorciado), foram utilizados com 0,5 tambaqui/m² e 0,1 jaraqui/m². Após 371 dias, os tambaquis apresentaram crescimento de 18,6±4,5 g para 997,1±195,08 g no Viveiro A e de 81,4±18,8 g para 519,9±191,7 g no Viveiro B.

Abstract:
Amazonia is considered to host some of the more productive freshwater fisheries of the world, and these are of key importance to the local population. Accordingly, fishing activity needs to be studied to evaluate its dynamics, so that long-term sustainability of the resource can be assured the fishing. The objective of the current study, therefore, was to analyze seasonal and spatial variation in the production of fish landed in the city of Manacapuru, in Central Amazonia. The landing data was collected daily from January to December 2012 at the main port of landing in Manacapuru, Amazonas, Br

Abstract:
Information on larval fish feeding is essential for understanding their trophic relations, including the management in conditions totally or partially controlled by humans. An experiment was designed to evaluate the larval diets of three commercially important species. Four varzea-lakes and the adjacent river were sampled with bongo and hand nets from January 1993 to November 1995. Larval diets were evaluated by length-classes and capture sites, and were tested by two factor ANOVA. The larvae were feeding in all habitats, except in the flooded forests. The three species had different diets, wh
