Internal current generation in respiration chambers
- 87 Downloads
A technical device generating a constant and directed current within a sealed respiration chamber is described. It does not involve any external pumps or tubing. This system is easy to handle, and improved the maintenance of rheotactic pelagic species like the Northern krill (Meganyctiphanes norvegica, Crustacea) or small fishes (Gasterosteus aculeatus) under experimental conditions.
