Estimation of fish yield potential in lakes, fish assessment in Lake Werbellinsee
Applicant: As./Prof. Jan Kubečka, PhD.
Project partner: Institut für Binnenfischerei e.V. Potsdam-Sacrow
The investigations were be carried out on Lake Werbellinsee in September 2009 by using the following methods:
- Hydroacoustic survey by scientific echosounder (two day and night surveys)
- 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).
