Estimation of fish yield potential in lakes, fish assessment in Lake Werbellinsee

Project No.

Applicant: As./Prof. Jan Kubečka, PhD.

Project partner: Institut für Binnenfischerei e.V. Potsdam-Sacrow

Duration: 2009-2010

The investigations were be carried out on Lake Werbellinsee in September 2009 by using the following methods:

  1. Hydroacoustic survey by scientific echosounder (two day and night surveys)
  2. Survey of the open water fish by fry trawls (approximately 20 trawlings by 3x3 m trawl)

The emphasis of the survey work was on the population assessment (abundance, spatial and vertical distribution, species and size composition) of vendace (Coregonus albula) and smelt (Osmerus eperlanus).
