Abstract
Abstract A modified design of a windermere trap, suitable for the capture of small fish, is presented. In direct comparison with more conventional gear, the trap was equally efficient in 26 southern Ontario lakes for pumpkinseed (Lepomis gibbosus) and brown bullhead (Ictalurus nebulosus). Efficiency was slightly reduced for largemouth bass (Micropterus salmoides), smallmouth bass (Micropterus dolomieui), yellow perch (Perca flavescens), rock bass (Amploplites rupestris), and golden shiner (Notemigonus crysoleucas). Length selectivity bias was minimal. Unlike standard gears, the trap weighs 1.5 kg, is stackable, and can be manufactured for approximately $10 (Canadian) in materials cost (polyvinyl chloride tubing, fiberglass flyscreen, and bamboo stakes) plus 4 hours of labour. Minimal impact on populations is possible because fish are captured live. The economy of construction and ease of deployment due to the light weight, stackability, and absence of leads or tensioning lines make it attractive for the s...
