Fish. Base can be utilized to produce simple, but effective posters: …. . customized for a fishery, a fishing area, fishing gear, fish market, etc. A simple poster showing the actual lengths of fish species at first maturity can be a useful management tool. Posted in public places (e. g. public market), consumers can compare the size of the fish they buy with the pictures in the poster and know whether the fish has reached maturity. 19/32
