Examining all inputs into maturation and early stages of larval culture is critical
Control of Vibrio bacteria should focus on minimizing overall bacterial loads and the potential for horizontal transmission. The challenge for hatchery managers
Perhaps the single greatest problem affecting shrimp hatcheries is high mortality in the early stages of larval culture. The term “zoeae syndrome” was coined to describe the affected stage. Typically, the animals do not molt from Z1 to Z2, and very high levels of mortality ensue. Various strains of Vibrio bacteria have been implicated in this process.
Assuming the water in production systems is properly treated and that an effective tool for managing microbial loads in production tanks is used, perhaps the greatest sources of contamination from bacteria in the early life stages are Artemia and algal culture systems….
