Capture and handling of fish for electronic tagging - a review and a new non-intrusive capture method.

摘要

While tagging procedures are described in details the capture and handling ofexperimental fish prior to tagging is not given the same attention in most papers.However, traumas that originate from the capture and handling process may for avarying penid of time iradluenca: the post-release behaviour of the animals studiedwith Smart-or other electronic tags introducing errors when interpreting the datacollected. With emphasis on Atlantic species, the paper gives an overview of captureand handling methods reported in electronic tagging experiments, and where relevant,references are made also to methods used to capture and transport fish for aquarium orother live holding purposes. The advantages and disadvantages of different handlingmethods are discussed, and a promising new &awl-method for cindividuals of delicate species is summarised.
