Management area for the signal crayfish

The management area includes the part of Sweden where signal crayfish is mainly established and where it can continue to be used. The purpose is to show where fishing may be conducted, provided that the signal crayfish does not spread. Outside the management area, handling, including fishing, is illegal. It is therefore important that detailed boundaries exist. The amount of information includes boundaries consisting of municipal and county boundaries, national roads and boundaries for sub-catchment areas.本管理区域涵盖瑞典境内信号小龙虾（signal crayfish）主要定植且可继续开展相关作业的区域。本数据集的设立目的为明确可开展捕捞作业的范围，前提为信号小龙虾未发生扩散。管理区域外的任何处置行为（含捕捞）均属违法，因此划定详细的区域边界至关重要。 本数据集包含的边界信息包括市镇界、郡界、国道以及子汇水区边界。
