“…Kapetsky (1978) published the results of one successful rotenone sample. Richter & Nijssen (1980) published the results of two gill net samples (open water habitat) and two rotenone samples (shore habitat). Our own collecting efforts in 2002-2005 were realized 40 years after closing of the dam and 34 years after the reservoir was filled.…”

“…Ouboter & Mol (1993) listed 86 fish species for the middle and upper Suriname River, but they did not examine the Boeseman collection. In 1967, Nijssen ( , 1969; also see Richter & Nijssen, 1980) collected only 62 fish species in Brokopondo Reservoir and in 1978 the number of reservoir fishes further declined to 37 species (Kapetsky, 1978;Richter & Nijssen, 1980). No surveys of Brokopondo Reservoir fishes have been carried out in the period 1978-2000 and it is not clear to what extent the reservoir fish communities had stabilized in 1978.…”

“…Although Boeseman (1964) presented a tentative and incomplete list of fish genera of the Suriname River and certain taxa in his collection were studied in taxonomic revisions (e.g. Boeseman, 1968Boeseman, , 1971Boeseman, , 1982Nijssen, 1970;Géry, 1972;Mees, 1974;Kullander & Nijssen, 1989), his large collection of Suriname River fishes was never studied in its entirety.In the filling stage (1964)(1965)(1966)(1967), the fish fauna of Brokopondo Reservoir was studied by Mees (1967) and Nijssen ( , 1969.In the post-impoundment stage, the fish fauna and fishery potential of Brokopondo Reservoir was studied in 1978 by Kapetsky (1978) and Richter & Nijssen (1980).

“…No substantial fishery has developed on the reservoir during its 40-year existence: fishing on a commercial scale is non-existent and subsistence and sport fishing are little developed (e.g. Kapetsky, 1978;Richter & Nijssen, 1980). …”

We investigated long-term changes in the fish fauna of Brokopondo Reservoir, Suriname, the first large reservoir (1560 km 2 ) that was created in tropical rainforest. Before closure of the dam in 1964, the fish fauna of Suriname River had 172 species, high diversity and high evenness. The riverine fauna was dominated by small-sized species, but no single species was dominant in numbers. Large catfishes were dominant in biomass. Species were evenly distributed over riverine habitats: rapids, tributaries and main channel. Four years after closure of the dam, only 62 fish species were collected from Brokopondo Reservoir, but the composition of the fish fauna was still changing. The reservoir fauna in 1978 was very similar to the reservoir fauna in 2005, indicating that a stable equilibrium had been reached 14 years after closure of the dam. The reservoir fauna had 41 species, low diversity and low evenness. Most species of Suriname River and its tributaries with strict habitat requirements did not survive in Brokopondo Reservoir. Fish community structure was different among four habitats of Brokopondo Reservoir. The openwater habitat (10 species) was dominated by the piscivores Serrasalmus rhombeus, Acestrorhynchus microlepis and Cichla ocellaris and their prey Bryconops melanurus and two Hemiodus species. B. melanurus fed on zooplankton, Culicinae pupae and terrestrial invertebrates. Hemiodus fed on fine flocculent detritus, demonstrating that the detritus-based food chain was still important in late stages of reservoir development. Serrasalmus rhombeus also fed on peccaries that drowned when swimming across the large reservoir in rough weather. The shore community (27 species) was dominated by seven cichlids, but early stages and juveniles of the open-water species S. rhombeus and B. melanurus also occurred in the shore habitat. Fish biomass in the shore habitat was 66.5±59.9 kg ha -1 . The cichlid Geophagus surinamensis and the characid B. melanurus had a lower biomass in Brokopondo Reservoir than in Suriname River. Serrasalmus rhombeus showed reduced body length in Brokopondo Reservoir as compared to riverine populations.Foram pesquisadas as modificações a longo prazo na ictiofauna do reservatório de Brokopondo, o primeiro de grande porte (1560 km 2 ) construído em floresta tropical úmida. Antes do fechamento da barragem em 1964, a ictiofauna do rio Suriname possuía 172 espécies, com diversidade e equitabilidade altas. A fauna do rio era dominada por espécies de pequeno porte, mas nenhuma delas dominava em número de indivíduos. Em termos de biomassa, os grandes bagres eram dominantes. As espécies estavam homogeneamente distribuídas nos diferentes hábitats: corredeiras, afluentes e canal principal. Quatro anos depois do fechamento da barragem, somente 62 espécies de peixes foram coletadas no reservatório de Brokopondo, mas a composição da ictiofauna ainda estava mudando. Em 1978, a ictiofauna do reservatório era semelhante à de 2005, indicando que um equilíbrio estável foi atingindo 14 anos depois do fechamento ...
