Individual identification methods are commonly used in fish research, including studies on size of stocks, growth rates, migration patterns, behaviour and genetics. In aquaculture, such methods can be used to calculate growth rates and to aid identification of fish that have escaped. Fin clipping has often been used in breeding programs. Since these programs employ large numbers of fish and are carried out over a long period, it is possible to observe any effects on growth and survival as an effect of fin clipping. Various types of fin clipping have been the subject of research. Studies on the effects of total or partial removal of different fin types have been conducted on many different species.
Contents: criteria for marking methods, legal requirements, types of fin clipping, advantages and disadvantages, literature references.
