European sea bass is a high-value Mediterranean aquaculture species facing growing scrutiny over welfare practices across its production cycle.
Sea bass welfare challenges span the entire production cycle — from hatchery through grow-out, handling, transport, and slaughter. The high commercial value of sea bass creates economic pressure to minimize losses, but this does not always translate to welfare improvement. Handling injuries, crowding stress, and inadequate slaughter practices remain widespread. Consumer markets in Northern Europe are increasingly demanding welfare-certified Mediterranean sea bass, creating market-based incentives for improved practices. Producers investing in welfare improvements often see reduced mortality and better growth rates, supporting the business case for higher standards.
