The vertical distribution of fish in the open water area of a deep temperate mesotrophic lake assessed by hydroacoustics and midwater trawling
Original language description
The fish stock of a deep temperate, mesotrophic lake was sampled at different depths using a fixed-frame fry trawl, during two nights in mid-September 2009. Additionally, horizontal and vertical hydroacoustics were used simultaneously to evaluate fish abundance and biomass estimates obtained by the trawl. Roach Rutilus rutilus and smelt Osmerus eperlanus were the dominant species of young-of the-year (YOY) fish in the trawl catches from the surface layers (0?9 m). Bleak Alburnus alburnus dominated the catch of older fish in the upper part of the surface profile (0?6 m). Around the thermocline (9?13 m) smelt dominated the catches of both the YOY and older fish. Beneath the thermocline (13?36 m) vendace Coregonus albula dominated the catch of YOY fish, and smelt was the only species of older fish in the trawl catches. Species composition, abundance and biomass of the YOY and older fish were heterogeneous throughout the depth profiles of the lake, but only abundance differed significantly
