What are 4 production phases in aquaculture?

The four production phases in aquaculture are hatchery, nursery, grow-out, and harvest. In the hatchery phase, eggs are fertilized and incubated until they hatch into larvae. The nursery phase involves rearing the young fish or shellfish in controlled environments to ensure their growth and health. During the grow-out phase, the organisms are raised to market size, and finally, in the harvest phase, they are collected and processed for sale.
