3.1. 3-L and 9-L tank designs
Both the 3-L and 9-L tank designs have been highly effective
in well-replicated experiments on low fecundity ornamental fish.
These micro-recirculating tanks maintain a uniform environment
and prevent the aggregation oflive prey and settling ofalgal pastes.
Water exchange is performed easily; eliminating the need to handle
or stress larvae while replacing old water, live prey and algae paste,
when the tanks are placed in a water bath linked to a recirculating
system.
