Artificial Substrates in Zero-Exchange Systems

 

From Abstract: In this study, under winter conditions, the effects of artificial substrates in an indoor zero-water-exchange system on Litopenaeus vannamei were investigated.  Growth, survival, feed conversion and water quality were compared between an artificial substrate group and non-substrate control group.  Survival and growth were significantly higher in the substrate group, and ammonia and nitrite-N concentrations, the total heterotrophic bacteria and Vibrio levels and feed conversion ratios were significantly higher in the non-substrate group.  Results from this study indicate that the utilization of artificial substrates in indoor shrimp culture system could effectively control water quality, improve the survival and growth of shrimp and significantly reduce feed conversion ratios.
