Zoea Syndrome |
||||
| Zoea syndrome is a condition where larvae stop feeding at zoea 2 stage and spend like 4-5 days without molting
to the next stage. Larvae don't eat, have no feces, and are totally white and without lipids. Mortalities can go
up to 80-90%. It is suspected to be caused by a vibrio. Some of the prevention methods used are: reducing the stocking period of the hatchery to no more than 3 days, probiotics and strong asepsis. Instant Algae Tetraselmis has been used for several years with very good results in hatcheries that are suffering from zoea syndrome. Tetraselmis contains natural amino acids that stimulate feeding in larval shrimp, and very high lipid and protein levels to provide them with the nutrients they need. In recent months some hatcheries have also experimented with feeding rotifers during the Zoea, mysis, and PL stages. The early results are very good but more studies need to be done before we have good quantifiable results. |
