Water quality

Achieving and maintaining good water quality through all stages of production plays a major role in overall fish health and performance.

Muhammad Kasnir et al, Indonesia Moeslim University, Indonesia, carried out physicochemical studies to asses water resource in Mangara Bombang District, South Sulawesi in relation to their potential for shrimp aquaculture use.

Nitrite is toxic to fishes and is often encountered in recirculation aquaculture systems. Accordingly, the nitrite tolerance of potential aquaculture candidates needs to be assessed before the fish can be farmed in land-based recirculation systems. In the pres…

Due to nitrate accumulation during nitrification and low water-exchange rates in recirculating aquaculture systems (RAS), nitrate levels can build up. Hendrik Monsees has therefore investigated the effect that exposose to high nitrate concentration has on juve…

To test whether digestion affected swimming performance in an active forager and whether the possible effects varied with temperature, Jing Peng et al, Chongqing Normal University, investigated the critical swimming speed (Ucrit) and the resting and active met…

Any fish farmer that wants to record a high survival of fishand better growth in record time in their ponds must endeavour to paygood attention to pond water quality, writes Lanre Ogunsina.
