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 organizing regions.

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. Two symmetric polarcapsules measured 5.9 ± 0.4μm long and 3.4 ± 0.5μm wide, each having a polar filament with 7-8 coils slightly obliquelyto the longitudinal axis of the polar capsule. The polar capsule wall measured ~0.4μm thick and was constituted by a hy-aline substance (~0.25μm thick) surrounded by a layer of electron dense granular material (~0.15μm thick). In this paper the Amazonian region, which was previously described based on light microscopy (Eiras et al. 2005b).we present, by the first time, ultrastructural aspects of the spores of Myxobolus insignis found in a teleost collected from

Estudou-se o tempo de conservação em gelo de 339 amostras de jaraqui escama fina (Semaprochilodus taeniurus)e 361 amostras de jaraqui escama qcossa (Semaprochilodus insignis).As amostras estudadas foram divididas em 17 lotes, dos quais se estudou as medidas morfométricas, peso e rendimento, bem como os testes sensoriais das características: EXTERNA, INTERNAS e ODORES DAS GUELRAS. A pontuação foi atribuida por uma equipe com um mínimo de 05 avaliadores. A chave proposta para avallar o frescor, ficou com 25 pontos para peixes recém-capturados e 08 pontos mínimos quando se tornava impróprio para consumo humano. Apresenta-se a composição centesimal dos lotes e as determinações de qualidade, tais como: pH, Rancidez oxidativa do músculo pelo método (TBA), Bases Voláteis Totals (BVT) e Trimetilamina (TMA). A duração média da conservação no gelo foi de 19,5 dias para o jaraqui escama fina e 17,5 dias para o jaraqui escama qrossa.

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. O manejo alimentar do Viveiro A pode ser uma alternativa sustentável de produção de tambaqui em substituição às rações comerciais.

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, Brazil. Results indicate that lakes were most frequently visited by fishermen, but that rivers had higher catch values. In total, 39 species of fish were landed, with jaraqui escama grossa (Semaprochilodus taenirus) and jaraqui escama fina (Semaprochilodus insignis) being the species most exploited by fishermen. Landing had a seasonal character, with higher values in the rising and high water periods. Significant differences were observed between the different seasonal periods, with peak-flood period having the highest catch per unit effort (CPUE) values. Principal Component Analysis (PCA) revealed that fishing gear varied according to the fishing environment and exploited species.

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, which varied with their length and lake. The rotifers were the main initial food item of the three species, replaced by fish larvae in Brycon cephalus, cladocerans in Triportheus elongatus and detritus in Semaprochilodus insignis. The increase of the ingestion limit, as the larvae grew, was higher than the increase in the consumed prey size for the three species.

Abstract:

taxa de evacuação gástrica é uma variável importante para estimar o consumo diário de alimento e portanto a pressão de predação que um piscívoro exerce sobre as presas. Esta taxa pode ser influenciada pela temperatura, tamanho do predador e pelo tipo de alimento. Neste trabalho medimos experimentalmente os efeitos que estas três variáveis exercem sobre a evacuação gástrica de Pygocentrus nattereri, um dos principais piscívoros da Amazônia. Para isso foram utilizadas temperaturas variando de 27° a 31°C e os seguintes itens alimentares: músculo e nadadeira de Semaprochilodus insignis e gafanhoto da espécie Paulinia sp. Estes alimentos compõem a dieta silvestre da piranha. O tamanho da piranha não influenciou na evacuação gástrica. Músculos obtiveram uma taxa de evacuação gástrica de 18,3% h -1, enquanto que nadadeira e gafanhoto obtiveram uma taxa média de 10,7% h -1. O efeito da temperatura foi mais pronunciado quando o item alimentar era músculo do que com nadadeira e insetos.

Abstract:

El ambiente de macrófitas acuáticas desempeña un importante papel como sítio de alimentación de peces juveniles del Orden Characiformes en la várzea de la Amazonia Central. En el presente trabajo fueron evaluadas las variaciones ontogenéticas en la dieta, en función del aumento corporal de juveniles de Brycon amazonicus, Triportheus angulatus, Mylossoma duriventre y Semaprochilodus insignis recolectados en bancos de macrófitas en un trecho del río Solimões/Amazonas. Fueron analizados 1.181 ejemplares, los especímenes fueron divididos arbitrariamente en tres clases de desarrollo de acuerdo con la longitud estándar (CP): clase I (15-30 mm), clase II (31-45 mm) y clase III (46-60 mm). Para el análisis de la dieta fue calculado el Índice Alimentar (IAi), combinando los métodos de frecuencia de ocurrencia y volumen relativo. Fueron observadas variaciones ontogenéticas en la dieta de M. duriventre y de T. angulatus durante la fase juvenil. Todas las especies muestreadas poseen forrajeo selectivo y llegan al fin de la fase juvenil con comportamiento trófico semejante al que presentan en la fase adulta.

Abstract:

Este estudio describe la fauna de parásitos y la relación hospedero-parásito en Semaprochilodus insignis Jardine, 1841, encontrados en el Lago Coari, tributario en el centro del Rio Solimões (estado del Amazonas, Brasil) en la Amazonia central. De 56 peces examinados, el 23,2% tenía las branquiasparasitadas por Gyrodactylus gemini Ferraz, Shinn y Sommerville 1994 (Monogenoidea: Gyrodactylidae) y el intestino por Procamallanus inopinatus Travassos, Artigas y Pereira, 1928 (Nematoda: Camallanidae). La tasa más alta de infección fue causada por G. gemini. El factor de condición relativa (Kn) no se vio afectado por el parasitismo, pero había una correlación positiva entre la intensidad de los helmintos y Kn, y la longitud total de los hospederos. Este es el primer registro de la fauna de parásitos de S. insignis con la ocurrencia de G. gemini y P. inopinatus para este hospedero Neotropical de la Amazonía.
