| Abstract: | The tambaqui, Colossoma macropomum , 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, AT=0·227 year-1, M=0·45 year-1. A yield per recruit analysis shows that the stock is underexploited for values of M bigger than 0·30 year-1. |
