Of course the vannamei shrimp life cycle is completed in one year. That is it.
Then they naturally die. That is the inbred nature of the Pacific shrimp vanna.

Those that survive their early years in the wild get to reproduce.
Others eaten by animals higher up food chain.
Farming domesticated shrimp is a multiplier to support existing wild….
