Monitoring small fish populations in streams: A comparison of four passive methods
We analysed the relative efficiencies and size-selectivities of four different passive capture methods in a small coastal stream. We used plastic minnow traps (PM), metal minnow traps (MM) and two types of fyke nets differing in mesh size (F1, small meshed; F2, large meshed) to capture over 12,000 f...
