As a recreational angler, I need to understand the regulations for fishing in rivers that flow into the sea in Sweden. Who regulates this type of fishing and what is the main reason for these rules? Also, find and define 'handredskap' (hand-held gear) using the website's glossary.
Navigate to the 'Fiske i vattendrag' (Fishing in watercourses) section. Identify the regulatory authority and the main purpose of the regulations for fishing in watercourses emptying into the sea. Navigate to the 'Om Svenska fiskeregler och hjälpsidor' (About Swedish Fishing Regulations and Help Pages) section. Locate and navigate to the 'Ordlista' (Glossary) section. Scroll through the glossary to find the definition for 'handredskap'. Extract the definition of 'handredskap'.
State that the primary regulatory authority for fishing in watercourses emptying into the sea is Havs- och vattenmyndigheten (Swedish Agency for Marine and Water Management) and their regulations (FIFS 2004:37). State that the main purpose of these regulations is primarily to regulate fishing for migratory species like salmon, trout, and eel. Provide the definition of 'handredskap' as: 'spö, pilk och liknande rörligt redskap som är utrustat med lina och högst tio krokar (typ av rörligt redskap)' (rod, jig, and similar movable gear that is equipped with a line and a maximum of ten hooks (type of movable gear)).
