“…This involves a reduction in costs, along with an increase in production intensity and efficiency, disease control and significant investment in modern technology (Wedekind et al 2001). The primary goal of rational pond management is to use existing conditions in the ponds to produce fish in order to maximise economic return to the farmer (Turkowski & Lirski 2010).…”

Appropriate supplementary feeding is of increasing importance in common carpCyprinus carpio pond aquaculture, not only with respect to production issues but also as a sustainable tool for maintaining environmental quality. We studied the effect of different supplementary feeding regimes (no supplemental feed, cereal grains, pelleted feed, pelleted feed with lowered phosphorus content, and extruded feed) on growth performance, water quality, natural food availability, phosphorus budget, fish body composition and economic performance in 10 experimental ponds stocked with 3 yr old carp at a density of 363 fish ha −1 over a 4 mo period. The type of supplementary feed had no significant influence on water variables, with the exception of lowphosphorus pelleted feed which increased conductivity (p < 0.05). No significant differences were observed in zooplankton density. Harvested fish had significantly (p < 0.05) higher dry matter content and considerably higher phosphorus content under all treatments compared with fish at the beginning of the experiment. The use of cereals and extruded feed improved carp growth, while the physical qualities of the feed (higher resistance to nutrient leaching) resulted in lower nutrient concentrations in effluent water. Profitability was increased with application of cereal grains and decreased with all pelleted and extruded feeds. Hence, the use of cereal grain feed generated higher economic and environmental benefits than selected pelleted and extruded feed.

“…It is worth reminding that the Pantanal is one of the most famous places in Brazil for sporting fishing due its high fish abundance and to the appeal of the media in general, mainly through magazines and radio and TV programs addressed to the public, delivering an image of a fishing paradise. In the State of Saxony-Anhalt (Germany), this figure is only 0.71 kg/day (Wedekind et al, 2001). For better comparison we should include the fishing effort figure (kg/fisher*area), but even so, we must emphasize that most sport fishing in Europe comes from artificial fish stocking, which is not the case here.…”

“…In Cachoeira de Emas, most of the sport fishers are men as is usual elsewhere, as in Finland (Salmi et al, 2006); in the Southeast area of England (Invest in Fish South West Report, 2007); in the State of Saxony-Anhalt, in Germany (Wedekind et al, 2001); in Liège, in Belgium (97.2%) (Frank, et al, 1998); marine fishers in northeast USA (80.1%) (Thunberg, 1999), in Guadiana, December. Some fishers (12.1%) even did not know which are the best fishing months and 10.3% mentioned the ones during the low water season, others the piracema, with any month for others.…”

“…Most of the fishers of Liège, travel 38 km by car on average, only 10% fish close to their residences (less than 3 km) (Frank et al, 1998). In the State of Saxony-Anhalt, in Germany, many fishers travel from 3 to 8 hours to fish (Wedekind et al 2001). Most of the sport fishers in France fish near home (47% -districts) or departments (43%) (Jantzen, 1998).…”

“…In the first half of the last century, in Germany, commercial fishing in rivers and lakes had great relevance; now, sport fishing is becoming more and more important (Wedekind et al, 2001). According to these authors, sport fishing is responsible for about 82% of the produc-fish tend to concentrate in large schools and so are more vulnerable, mainly during the upriver reproductive migration (known as "piracema") (Schubart, 1949;Godoy, 1974).…”

Keywords: inland sport fisheries, sporting fishers' socioeconomic profile, Mogi-Guaçu River, Brazil. A pesca esportiva na Cachoeira de Emas, Rio Mogi-Guaçu, Estado de São Paulo, Brasil ResumoA pesca esportiva é uma atividade importante de lazer em muitos países. Ela gera direta e indiretamente renda e emprego para milhões de pessoas. Em alguns locais seu desembarque supera a produção da pesca profissional, mas esse fato nem sempre é levado em conta no estabelecimento de políticas de manejo. Na região da Cachoeira de Emas, há relatos da sua ocorrência desde a década de 40. O objetivo deste artigo é identificar o perfil dos pescadores esportivos que frequentam esse local e caracterizar essa pesca. De fevereiro a outubro de 2006 foram entrevistados 107 pescadores esportivos que frequentaram esse local. A maioria dos pescadores são homens, procedentes do Estado de São Paulo, com renda média familiar de US$ 1.212.37 (R$ 2.558,10, US$ 1 = R$ 2,11, Julho/2007), com idade média de 50,2 anos e grande parte deles (49,5%) tem apenas o primeiro grau incompleto. As principais espécies capturadas são o curimba Prochilodus lineatus, mandi Pimelodus maculatus, P. heraldoi, P. spp., lambari Astyanax fasciatus, A. schubarti, A. altiparanae, Roeboides paranensis, e piava Leporinus lacustris, L. friderici, L. octofasciatus. Os pescadores têm ligação com esse local há muitos anos e, mesmo com seu baixo rendimento (2,8 kg/dia), a maioria acredita ter sucesso na pescaria.Palavras-chave: perfil socioeconômico dos pescadores esportivos, pesca esportiva, Rio Mogi-Guaçu, Brasil.
