katiskoilla

Katiskoilla is the inessive plural form of the Finnish noun katisko, meaning that multiple fish traps are located or used at a given place. The expression is common in descriptions of fishing sites where several traps are deployed in a body of water.

A katisko is a traditional fishing device, typically a woven basket or container with a funnel-shaped entrance that guides fish into a holding chamber while making it difficult for them to escape. They are used for catching various freshwater fish and crayfish and are common along Finnish lakes and rivers. Traditional constructions often employ wicker, willow, or other plant fibers, though modern versions may use wood or metal. Katiskoja are usually placed underwater and secured with weights or anchors and can be used singly or in groups.

Use and regulation: Katiskat have long been part of subsistence and small-scale fishing in Finland. Today their use is governed by local fishing regulations, which may require licenses, respect for seasons, size limits, and protections for certain species. Regulations vary by region, water body, and species targeted, and enforcement practices differ accordingly.

Etymology and related forms: The word katisko is Finnish, and katiskoilla denotes the locative plural form. Related terms include katiskat (plural) and the Swedish loanword katiska, which refers to a similar type of fish trap in some contexts. Katiskat are sometimes mentioned in cultural and historical descriptions of traditional Finnish fishing methods.
