A variety of boxes, troughs, aquariums and tanks, from 0.4 to 15 m2 in size, are optimal for egg, larval and young phase fish studies. 144 indoor tanks enable versatile study designs for fish breeding and rearing experiments or the construction of other test arenas with good repeatability. The hall also boasts other equipment e.g. swimming endurance test devices or small-scale flow-through troughs (fluviariums) equipped with camera or telemetry-antenna arrays for monitoring fish individually. Fish individuals for the experimentations are either raised in the station's own aquaculture unit or transported from other Finnish aquaculture stations and natural waterways.
