Combining fishery prohibition with stocking of landlocked salmon, Salmo salar L.: an effort to gain bigger yield and individual size
After stocking landlocked salmon, Salmo salar L., in Lake Änättijärvi, all fishing was prohibited for 18 months to provide time for the fish to establish and reach a larger size prior to capture. The potential benefit of the fishery prohibition was severely diminished by emigration of the stocked fi...
