“…Although we cannot estimate maximum movement distances for our marked fish, our results do not support the long-held view of restricted fish movement first proposed by Gerking (1953Gerking ( , 1959. Since his seminal work, research on fish movement has overwhelmingly supported the idea that stream fishes are restricted to relatively small areas (see review by Gowan et al 1994).…”

Recent research has suggested that the within-habitat dynamics of fish populations and assemblages can be affected by the spatial distribution of habitats within streams. In this study, we determined the extent to which pool isolation (length of riffles connecting adjacent pools) influenced fish movement in two Arkansas streams. We marked individuals from 12 pools assigned to two treatment categories: pools separated by long riffles (>50 m) and those separated by short riffles (~10 m). Repeatedly snorkeling pools for 3 days in 1995 and 1997, we discovered substantial emigration (>20%) and significant effects of riffle length. Total emigration from short-riffle pools was three times higher (29%) than movement from long-riffle pools (10%). Further, marked fish in short-riffle pools moved upstream and downstream with equal frequency, whereas fish in long-riffle pools moved twice as often downstream. Collectively, these results indicate significant effects of habitat spacing on short-term movement patterns by fish. In streams, where fish are distributed within a mosaic of habitats of varying quality, such movements may allow individuals to assess spatial variability in resource conditions (e.g., food, predators). Because land-use activities can alter habitat spacing, these findings have important implications for fish conservation in degraded streams.

“…Previous studies in tropical streams (e.g. Mazzoni, Iglesias-Rios, 2012;Mazzoni et al, 2015) revealed that fishes move longer distances than that mentioned by Gerking (1959). Mazzoni, IglesiasRios (2012) registered fish movement in a tropical stream and suggested that they were mainly motivated by reproduction.…”

“…According to the Restricted Movement Paradigm postulated by Gerking (1959), adult stream-dwelling fishes have a restricted home range, so they are sedentary and spend their life at restricted stream reaches (20 -50 m). The scientific community accepted this idea and some studies corroborated it (e.g.…”

Fish movement in an Atlantic Forest stream

et al. 2018

Given the importance of fish movement to the dynamics and maintenance of stream dwelling fish communities from the Atlantic Forest, we analysed patterns of fish movement in a coastal stream from Southeastern Brazil, using mark-recapture technique. Displacement distance of each species were presented and discussed considering seasonal (rainy and dry) and body size patterns. We marked 10 species along the stream and recaptured 440 (34.6%) of the 1,270 marked fishes. The species with significant number of upstream moving individuals were Astyanax janeiroensis, Characidium interruptum, Astyanax hastatus, Parotocinclus maculicauda and Awaous tajasica. Only Pimelodella lateristriga presented significant differences between resident and moving individuals. Characidium interruptum and A. tajasica demonstrated greater downstream and upstream movement, respectively, moving up to 2,100 m. Even after controlling for species identity we found no significant correlation between fish length and individual displacement distance. Fishes moved longer distances during the rainy season, in accordance to the breeding season. Patterns of fish movement were in agreement to life-history traits of many of the studied species and can be reflecting specific behaviour and morphologies.Keywords: Coastal stream, Migration, Reproduction, Stream dwelling fish.Considerando-se a importância do movimento de peixes para a dinâmica e manutenção das comunidades de peixes de riachos da mata Atlântica, nós analisamos os padrões de movimento de peixes de um riacho costeiro do sudeste do Brasil, usando a técnica da marcação e recaptura. Avaliamos a distância do deslocamento de cada espécie e também se os padrões de movimento apresentavam alguma relação com a estação do ano (chuva e seca) e o tamanho do corpo. Marcamos 10 espécies ao longo do riacho e recapturamos 400 (34.6%) dos 1.270 peixes marcados. As espécies com número significativo de indivíduos se movendo para cima foram Astyanax janeiroensis, Characidium interruptum, Astyanax hastatus, Parotocinclus maculicauda e Awaous tajasica. Apenas Pimelodella lateristriga apresentou diferenças significativas entre os indivíduos residentes e em movimento. Characidium interruptum e A. tajasica foram as espécies com maior movimento tanto para baixo como para cima, respectivamente, se movendo até mais de 2.100 m. Mesmo após controlar a identidade das espécies, não registramos correlação significativa entre o comprimento e a distância individual do deslocamento. Registramos maiores densidades de peixes se movendo para montante durante a época de chuvas, em coincidência com a estação reprodutiva. Os padrões de movimento registrados estão de acordo com os componentes da história de vida de várias das espécies estudadas, e podem estar refletindo componentes morfológicos e comportamentais específicos.Palavras-chave: Migração, Peixes de riacho, Riacho costeiro, Reprodução.

“…All species combined, as well as individual species, did not respond to such stressors as the stream channelization and climate changes at any significant level in the Dobrzynka Stream. This may be partly explained by the fact that dominant and subdominant species in the Dobrzynka Stream have calculated median displacement (MD) close or smaller than the home section lengths (HSL: 100 m, sensu Gerking, 1959), with exception of gibel on one sampling occasion. These results were congruent with estimated low turnover rate (TR) for the investigated species, which was significantly correlated with MD, and congruent with the Gerking's restricted movement paradigm (RMP), which was tested directly in this stream (Penczak, 2005).…”
