Electric Fishing

We electric fished two sites yesterday for different private clients, on two very different sites, one has had instream improvement work done by us over the last five years and the other site has had very little work done, the contrast, in terms of fish population was very obvious. 

We offer electric fishing work at a very competetive price, and all our clients recieve a written report on the survey work carried out.

 

Electric fishing is a very useful fishery management tool;  its two main roles are to survey fish populations and communities and for stock manipulation i.e. culling of predators/coarse fish removals.

Electric fishing surveys provide information on the fish community, including population structures, levels of recruitment, distribution and species range and where scales are taken age and growth rates can be calculated.

Data collected can then be interpreted and used to manage your fishery, it may identify limiting factors, for example, barriers to migration, impacts of predation, lack of spawning/nursery areas or poor water quality. It may also be used to determine stocking requirement/success, or highlight areas suitable for habitat enhancement.

  • We are equipped to carry out the following
  • Small stream surveys-using back pack electric fishing and 2-3 staff
  • Small river surveys-using a boat/wade electric fishing and 3-4 staff
  • Large river surveys-using boat electric fishing and 5 staff

Where possible catch depletion surveys (quantitative) are undertaken to provide a higher level of confidence in the data collected, single run (semi quantitative) and timed surveys (catch per unit effort) can also be carried out. Environmental factors such as habitat types and water quality parameters are recorded on all surveys.

Electric fishing surveys are carried out by our experienced staff and any disturbance to the aquatic environment is kept to a minimum.
