The salmon fishery of the Penobscot basin is carried on with practically a single type of apparatus, namely, the brush weir. In most parts of the region this trap is used in the same form that it had in the primitive days of the fishery, but in some sections the weir has undergone evolution into a combination brush and twine trap, and in places into a trap made wholly of netting. Some of the types of salmon nets used in this region are illustrated and described by the accompanying figures. In addition to these, which are wholly or partly of brush, a common apparatus is the floating trap, constructed entirely of twine, such as is now generally employed in the New England States. This is the only salmon net in use at Islesboro and in some other sections. The local and individual variations in the form of the nets depend on the topography of the bottom and shore and the habits of the salmon, and are the result of long experience. The fishing begins as soon as the ice moves out in spring and continues until some time in July. Fish are rarely taken before the last two weeks in April. May and June are the best months. In that part of the river adjacent to Bangor there is a small fishery prosecuted with set gill nets. The nets are from 100 to 200 feet long and have a 6-inch mesh. Salmon weir, Castine.
