| Abstract: | The River Todasana is a small rain tropical forest stream emptying to the Caribbean Sea (Venezuela). Fish were sampled by
electrofishing at three contiguous sites (pool, riffle, raceway). Nine species were recorded. Their mean biomass and production
were: 43.72 kg ha−1 and 36.94 kg ha−1 yr−1, maximum: 55.47 kg ha−1 and 42.33 kg ha−1 yr−1, respectively. |
