The fabric had gaps approximately 0.7 mm in diameter, which allowed for water exchange between the chambers and the pond but did not allow entry of amphipods and larger organisms.
In all cases, there was no water exchange during the study, only the replacement of loss due to evaporation by adding seawater (0.5% [week.sup.-1]).
There are several solutions for water quality improvement, such as traditional method (Jackson et al., 2003) with increasing water exchange, recirculating aquaculture system (RAS) (Kolarevic et al., 2012) with waste treatment infrastructures and biofloc technology (BFT) with zero-water exchange (Avnimelech, 2006).
Good water exchange is also important in cage culture to replenish oxygen and flush away wastes.
Water exchange was carried out periodically with 10% volume of each pond in order to maintain the quality of the water.
We have recirculating aquaculture systems [RAS] where water exchange is limited.
With land-based systems, natural processes such as filtration and water exchange and dispersal must be carried out mechanically, which requires a lot of electricity.
"Most of the ships that we get are from the same region, so the question of ballast water exchange doesn't arise.
Recirculating systems, such as those pioneered at TCFFI, use as little as 4 percent new water each day, which means that a complete water exchange takes place once every 25 days.
No water exchange was performed over the entire experimental period in any of the culture tanks, just the replenishing to maintain the initial water level.
