Implication

Controlled study reveals that pre-slaughter anoxia accelerates fillet quality deterioration in largemouth bass, highlighting the direct link between fish welfare and post-harvest meat traits.

Key Points

Pre-slaughter handling with anoxia promotes rapid fillet quality deterioration in largemouth bass, driving accelerated muscle oxidation and premature loss of tissue hardness.
Onset of rigor mortis occurred at 6 h in anoxia-exposed fish compared to 10 h in controls, and initial fillet quality hardness fell under elevated stocking density.
Western blot analysis and blood chemistry tracked largemouth bass across three stocking density groups in a recirculating aquaculture system over a 12-week trial.
Highlights that minimizing pre-slaughter handling stress protects fillet quality, while reducing stocking density enhances welfare in commercial bass aquaculture.
