Fish catches among riverside communities around Lago Grande de Monte Alegre, Lower Amazon, Brazil

Abstract

Forty‐six families living around the Amazon floodplain lake of Lago Grande de Monte Alegre, Brazil, were monitored between April 1993 and March 1995 with respect to their fish catches. The average catch per fisherman was 22 kg day‐1. There were significant differences between subsistence and commercial fishing, and also across different seasons of the year. Catch was higher in the dry season and in the lake environment, followed by the river environment. The flooded forest was exploited in the rainy season. Out of a total of more than 70 fish species, 10 taxa comprised 75% of the catch. The catch in the Monte Alegre region concentrated on smaller species for local consumption. Prochilodus nigricans (Spix & Agassiz) was the most important species, followed by Liposarcus pardalis (Castelnau) and Plagioscion spp. Comparisons between quantities of fish consumed and fish marketed indicated that the fishery has a much more important role in the region than previously thought.

Características De La Pesca Y El Aporte Nutricional Del Recurso Pesquero en La Comunidad Santa Rosa Del Aripari, Cuenca Del Río Cahuapanas

“…La pesca en la comunidad nativa Santa Rosa de Aripari reportó mayor biomasa durante la creciente, siendo dominada por especies de migración local como carachama sin costilla, fasaco y shuyo, cuyas capturas estuvieron asociadas a hábitats de poco flujo como los aguajales y las cochas, ideales para alimentación y reproducción de estas especies (Junk et al, 1989;Cerdeira et al, 2000;Moya et al, 2020). Estos resultados difieren a lo reportado por Bodmer et al, (2005); García et al, (2009); García et al, (2014); y Moya et al, (2020), para diferentes áreas de la región Loreto, en donde la mayor captura ocurrió durante la temporada de vaciante y dominada por especies de mediana migración como el boquichico.…”

SPATIAL AND SEASONAL VARIATION OF PEACOCK BASS (<i>Cichla</i> spp.) FISHERY: AN ANALYSIS OF CATCHES LANDED IN MANAUS, AMAZONAS STATE, BRAZIL

“…The inverse relationship between peacock bass catches and water level could be exacerbated in years of extreme floods, such as happened in 2012 (Cerdeira et al, 2000;Barthem and Fabré, 2004). Zuanon (2008) explains that extreme flooding events could be favorable to the fish stocks, since strong recruitments one or two years after these events could produce profitable fisheries, due the increase of juvenile survivors as consequence of higher availability of refuges against predators and food.…”

The Catfish Fishing in the Amazon Floodplain Lakes

“…The commercial fishing mainly focuses its productivity on the migratory species in the river channels [28] during the drought season, and explores the lakes focusing mainly on the genus Hypophthalmus species [29]Isaac, V.J. during the flooding period, when fishing in the river channel is poor and technically difficult.…”

“…Hypophthalmus spp. (mapará) fishing occurs in the flooded forest and shallow floodplain lakes of open water, where forest is scarce [14] and takes place almost all year long, but with greater intensity at the beginning of the flood period [28]. These species account for over 50% of the total landings in the Lower Amazon [18,22], rank among the most economically important fishery resources in the region [8] and play an important ecological function in the food chain because they are pelagic planktivorous resources and serve as food for several top predator fishes.…”
