Yield per recruit of the Tambaqui, Colossoma macropomum Cuvier, in the Amazonas State, Brazil

Abstract: The tambaqui, Colossoma rnacropornurn, is the most important fish landed at Manaus by the fishery in the Amazonas State, Brazil. Population parameters have been estimated for this stock, which are: L , = 107.3 cm (T.L.), W , =32 kg, K=0.227 year-', M=0.45 year+. A yield per recruit analysis shows that the stock is underexploited for values of M bigger than 0.30 year'.

“…A origem do pescado capturado também é descentralizada, conforme indicaram Petrere Jr. (1978;1982;1983) e Batista (1998), embora o percentual declarado no presente estudo, para viagens aos pesqueiros do rio Purus esteja aumentando sua importância como região de pesca para o abastecimento de Manaus (Batista, 1998;Soares & Junk, 2000). Pertencente à calha do rio Solimões, a região de Coari apareceu com destaque como contribuinte desse sistema para Manaus, sendo que tanto o rio Purus quanto o rio Solimões até este município deveriam ser prioritários nos estudos bio-ecológicos e de avaliação de impactos das ações antrópicas sobre os recursos pesqueiros.…”

“…This species was considered under-exploited by Petrere (1983b) until 1978, but Merona & Bittencourt (1988 A stock in the initial phase of exploitation shows higher mean size and lower growth rates than that subjected to a period of intensive exploitation (Hilborn & Walters, 1992 (Ribeiro, 1983;Zaniboni, 1985;Vazzoler et al, 1989;Oliveira, 1997 The exceptional total production for the month of May during the three years of this study is associated with the downstream migration of the fat fish, fishes with large energy reserves for migration and reproduction (Ribeiro, 1983;Batista, 1998). …”

“…The knowledge about fishing in Central Amazonia showed a great expansion at the end of the 1970's, when a generation of researchers developed a series of studies that rendered pivotal information for the understanding of the fishing activity (Petrere, 1978a(Petrere, /b, 1983a(Petrere, and 1985Goulding, 1979 and1981;Smith, 1979 among others), as well as about the dynamics of the exploited populations (Petrere, 1983b;Ribeiro, 1983;Bayley, 1983;Junk, 1984, among others). However, during the 1980's such studies became restricted to the contribution of Merona and co-workers (e.g.…”

“…The multispecific characteristics of the Amazon fishing and the unknowledgement of dynamic population of most exploited species do not allow the general use of traditional evaluation models (Petrere Jr., 1983a;. Other approaches aimed at obtaining estimates of the Amazon basin fishing potential and/or develop models to identify the factors which explain the captures have been developed (Bayley, 1981;Petrere Jr., 1983b).…”
