Electric fishing is a very useful fishery management tool; its main roles are to survey fish populations and communities, stock manipulation i.e. culling of predators/coarse fish removals, and carrying out fish rescues. Fish rescues fall into two main categories; firstly planned rescues as part of in-stream construction works and dewatering operations, and secondly unplanned fish rescues, where fish are rescued as a result of natural events such as drought conditions, or the impacts of abstraction or flow augmentation failures.Casterbridge Fisheries are set up to deal with all aspects of both planned and unplanned fish rescues, including removal, transportation and all relevant Environment Agency consents. Electric fishing surveys provide information on the fish community, including:
Data collected can then be interpreted and used to manage your fishery; it may identify current and potential limiting factors, for example:
We are fully equipped to carry out the following:
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. |
