Pesca e esforço de pesca no Estado do Amazonas. II - Locais, aparelhos de captura e estatísticas de desembarque

This paper is about the fish arriving in the market in Manaus during 1976. The total catch is estimated by using functional linear regression. Statistics of landing per month and per gear are furnished. In maps are shown the places of catches with their geographic coordinates and the distance from Manaus. The main fish caught is the Tambaqui (Colossoma macropomum) with 44.1% of the total weight (30800 t). The most used gear is the arrastão (a type of seine used in lakes and rivers) with 46.6% of the total catch. Data of landings at two places near Manaus were compared: the lago do Rei (699.21) and lago do Janauacá (1277.51).Este trabalho se refere ao pescado desembarcado no Mercado Municipal de Manaus em 1976. A captura total é estimada através de análise de regressão funcional linear. São fornecidas estatísticas de desembarque por mês e por aparelho São mostrados em mapas, acompanhados de suas coordenadas geográficas e da distância de Manaus, os pesqueiros nos diversos rios onde se realiza a pesca. O peixe mais capturado foi o Tambaqui (Coloesoma macropomum) perfazendo 44,1% do total geral em peso (30800 t aproximadamente). O aparelho que mais capturou foi o arrastão (48,6% do total geral). Foram comparados dados do desembarque de dois pesqueiros próximos a Manaus, o lago do Rei (699,2 t) e lago do Janauacá (1277,5 t)

Fish, Sorocaba river sub-basin, state of São Paulo, Brazil

In this paper we present a list of the fish fauna of Sorocaba river sub-basin. Fish were caught with gillnets, sieves and puçás, a sort of funnel net. We listed 71 species, distributed in 7 orders, 22 families and 50 genera. Characiformes are represented by 39 species, Siluriformes 21, Perciformes 4, Gymnotiformes 3, Cyprinodontiformes 2, and Synbranchiformes and Cypriniformes by a single species each. Five species are alien. Nine species remain as an indefinite taxonomical status

Fish, Itupararanga Reservoir, Sorocaba River Drainage, São Paulo, Brazil

The Itupararanga Reservoir is located at the Sorocaba River Basin, state of São Paulo, Brazil. Five cities use the waters of this reservoir for human consumption. Despite this intensive use of the water resource, no study has been undertaken, to investigate the ichthyofauna of this reservoir. Overall, 22 species of fishes were sampled, including 7 orders and 12 families. Characiformes and Siluriformes were the most representative with respectively 9 and 5 species. Among the families, Characidae and Pimelodidade are noticed, both with respectively 5 and 3 collected species

Diagnóstico da realidade alimentar e nutricional do Estado do Amazonas, 1978

An analysis of the food and nutrition situation in the state of Amazonas is made based on health statistics, types of malnutrition, dietary patterns, food consumption and production in the region. It is concluded that the sanitary situation of the population is precarious. The frequency of gastro-intestinal deseases is high, associated with pem and anemia. The diet is deficient in Vitamins A and B, principaly due to low vegetable consumption. Food production is stagnant with imports rising. These conclusions are discussed and recomendations made.O diagnóstico da situação alimentar e nutricional do Estado do Amazonas foi analisado baseado em dados do área de saúde, padrões alimentares, consumo e produção de alimentos e a ocorrência e tipos de mal nutrição. Concluiu-se que o situação sanitária no Estado é precária, com alta freqüência de doenças gastro-intestinais associadas com desnutrição proteico-calóríca e anemia, A dieta parece deficiente em vitamina A e B devido principalmente ao baixo consumo de verduras e legumes. A produção de aumentos está estagnada com aumento das importações. Essas conclusões são discutidas e recomendações são feitos

Fishes from the Parque Nacional do Pantanal Matogrossense, upper Paraguai River basin, Brazil

The Pantanal Biosphere Reserve contains one of the highest concentration of animal species in the Neotropics, including about 300 fish species living in diverse environments associated with wetlands in the upper Paraguai River basin. This biome spans portions of Bolivia, Brazil and Paraguay and includes the Parque Nacional do Pantanal Matogrossense (PNPM), a region of the Pantanal which has been assigned as high conservation priority in Brazil. This study reports the results of an ichthyological survey within the PNPM, where samples were taken at 12 sites during the dry season in 2001, 2010 and 2011. We record 182 species representing three classes, 10 orders and 41 fish families. We report the first occurrence of the genus Anchoviella (order Clupeiformes), in the La Plata basin. This survey will provide information for future studies concerning conservation and management plans for the PNPM as well as for the Pantanal, which is one of the largest permanent wetland areas in the world and among the most unique and important South American biomes

The horizontal migration of hammerhead sharks along the southern Brazilian coast, based on their exploitation pattern and considerations about the impact of anchored gillnets activities on these species.

Between 1995 and 2009 hammerhead sharks were sampled from the landings of the industrial fleets based in the harbours of Itajaí and Navegantes, Santa Catarina State, and Ubatuba, São Paulo State, Brazil. In this case, fishing boats which operated with gillnets longlines and trawls along the southern Brazilian Economic Exclusive Zone and international adjacent waters were targeted. A total of 2483 and 353 S. lewini and S. zygaena carcasses respectively were sexed, measured and converted to total lengths (LT). Additionally information about, year, season, latitude/longitude and local depth (m) from the catches, by fishing category, were obtained. During the considered period, intense fishing mortality over pups was caused by gillnets and trawls operating on shallow waters (≤ 20 m) and over juveniles along the continental shelf (> 20 m and ≤ 200 m). Additionally, adults were exploited by driftnets and longlines along the shelf border and slope (> 200 m). Therefore, both hammerhead species are exploited at all life-stages and throughout their migratory circuit. This includes during their inshore-offshore migration while they are growing from pups to juveniles and as the offshore-inshore migration of pregnant females to pupping areas in shallower waters. This apparently unsustainable exploitation pattern, over different size classes (newborns-juveniles-adults), and the economic pressure caused by the international fin market, is one of the reasons for population declining of these two species in southern Brazil. Non fishing zones for the hammerheads, protecting their migratory circuit, which is driven by their growth pattern and reproduction, are necessary. Additionally, fishing effort reduction and a control over the international fin market are recommended.

The variance of the index (R) of aggregation of Clark and Evans

The exact formula for the variance of the Index (R) of aggregation of Clark and Evans is derived. Due to the fact that R is a dimensionless number, its variance is independent of population density, being only a function of the sample size and so can be manipulated. © 1985 Springer-Verlag
