Bass Nursery Areas

There are regulations across the District regarding fishing within designated bass nursery areas. A booklet was produced by the Ministry of Agriculture, Fisheries and Food on Bass Nursery Areas and Other Conservation Measures which can be seen here. Minimum size for Bass was updated to 42cm by EU legislation introduced in 2015. Details can be seen here.
