[quote=Anonymous]Aquaculture is always susceptible to parasite and disease problems that occur after 3-4 years of continuous species cultivation. They really should be letting those ponds go dry every two years for a season, then rotating in a different species like catfish for 2-3 years. When you intensively farm one species in the same pond over end over, you accumulate parasite and disease loads in those ponds that are optimized for those species being farmed. So you get really high mortality, much higher than you’d have in nature with the same conditions. This is a lesson they learned in shrimp aquaculture decades ago in Asia. Now they rotate ponds every couple years and let previously used ponds stay dry for a couple years in between to kill off the parasites and pathogens. Same practice will be adopted here, they just need to reinvent the wheel again. [/quote]
