Biological sampling procedures for fish and crustaceans: Fin clip for genetics. Version 1.4

Abstract

Onboard the DF Nansen, genetic samples are usually taken from species with a large geographical range, and that are commercially important in a larger region. The results are used to study population genetics and connectivity. The results can also be used to study migration, sexual maturity and other biological processes. We might also take genetic samples for species identification for taxonomically challenging species. Normally the genetic sample taken onboard is a fin clip, which is what is described in this procedure. However, we might occasionally take a muscle sample (example sharks or rays) or a defined part of an invertebrate for genetic studies. The general procedure is nevertheless the same.
