Income evaluation of small - scale fishers in two brazilian urban reservoirs: Represa Billings (SP) and Lago Paranoá (DF)

Abstract: The income of small-scale fisheries of two urban reservoirs in Brazil: Represa Billings (127 km 2 ) located in the metropolitan region of São Paulo, the capital city of the state of São Paulo and Lago Paranoá (38 km 2 ) located in Brasília (DF), the capital city of Brazil were calculated and compared. Both fisheries are mainly based on the alien Nile tilapia Oreochromis niloticus (more than 80% of the total catch). Although these reservoirs are nearly 900 km apart, their native fish fauna belong to the Upper P… Show more

“…The homogeneity of gender and age in this study with those of other studies (Mauryama et al, 2009;Alves da Silva et al, 2009;Araya et al, 2009;Petrere Jr. et al, 2006) demonstrates a common profile for those who practice smallscale inland fishing.…”

“…Deslocamentos mais distantes do porto principal ou até mesmo das residências dos pescadores, número maior de dias de viagens, alta capacidade de armazenamento formam a dinâmica da pesca realizada por barcos de pesca na Amazônia (CARDOSO e FREITAS, 2007;GONÇALVES e BATISTA, 2008;ISAAC et al, 2008 Os valores de renda foram superiores aos observados por LIMA et al, 2012 em uma comunidade ribeirinha do médio rio Madeira (média mensal por expedição de R$ 465,00). Ainda assim, é necessário salientar que análises econômicas mais completas são difíceis de realizar, pois os registros não incluem despesas totais, como, a depreciação das embarcações e/ou dos apetrechos de pesca (PETRERE JR et al, 2006), bem como os rendimentos diários totais obtidos (KVIST et al, 2001).…”

“…Thus, the use of appropriate techniques by fishers made the Nile tilapia the main fish caught and high biomass. Nile tilapia are the dominant fish in many Brazilian reservoirs and lakes, such as northeastern dams (Paiva et al, 1994), the Pampulha Lagoon (Alvares et al, 2000), the Billings Reservoir (Minte-Vera and Petrere Junior, 2000) and the Paranoá Lake (Petrere Junior et al, 2006;Walter and Petrere Junior, 2007). These reservoirs are all characterised as eutrophic, supporting the hypothesis that eutrophication (or hypereutrophication as in Barra Bonita Reservoir) favours the proliferation of this species.…”

“…The beating gill net technique was probably introduced to the Barra Bonita fishery by fishers from the Billings Reservoir, which is about 300 km from Barra Bonita. Many fishers from the Billings Reservoir stopped fishing there because of increases in local urban violence, such as theft (Petrere Junior et al, 2006). Some of these fishers currently live in camps on the banks of the Barra Bonita Reservoir, where they continue the fishing techniques they used previously.…”
