摘要: The rapid development of the aquaculture industry in recent years and increase intensity production has raised questions regarding potential environmental impacts. Understanding intra- interspecific relationships between native cultured species is important for sustainable use natural resources. This study investigated spatial temporal effects a fish farm constructed next to river on relative abundance diversity populations. Sampling was conducted at three stations, upstream down stream from trout control site, Kocabas Canakkale (Turkey) monthly August 2015 July 2016. There no significant difference among stations diversity. However, remarkable seasonal variation composition proportion indigenous assemblage were observed stations. In conclusion, might have influenced abundances particularly downstream station.
