概

述
English: The first purse seines were light nets cast from heavy rowboats. In 1905 gas-powered engines were introduced and by 1911 the fleet used larger boats becoming less dependent on the tide; typical length averaged 55 to 70 feet. Salmon purse seines nets were made from cotton web coated with creosote and ranged from 900 to 1,200 feet in length and 25 to 40 feet in depth. The skiff driver led the net around the salmon and back to the seiner. A pull on the purse line closed the bottom of the net. The fish were tightly packed in a small volume of net called a “money bag.” A brailer scooped fish into the boat; one brail could bring in 2,000 fish per hour. In southeast, purse seining accounted for three-quarters of the salmon harvest. Survey number HAER AK-28
