A simple and inexpensive apparatus for providing natural prey in a laboratory environment

摘要

We present instructions for an inexpensive feeding apparatus for use in simulated (laboratory) aquatic environments where natural prey is required. We used this apparatus during juvenile salmonid competition trials where it was essential to provide real prey in as natural a manner as possible. We found that this apparatus not only outperformed commercially available feeders (which could not satisfy our research requirements) but could also be built for a fraction of the cost.
