Impulsive Sounds Trigger Stress Response in Farmed Seabream.
A single impulsive sound can be more than a passing disturbance for farmed seabream; it can register as a measurable stressor. New research on gilthead seabream shows that storm-derived noise triggers significant cortisol elevations, affecting fish at both individual and group levels. The study's use of plasma, water, and fin tissue to track stress across time is a practical step toward refining aquaculture practices. For those exploring broader acoustic impacts, our related coverage on ultrasonic exposure in marine invertebrates offers useful context.
CBD and Aeration Improve Stress Resilience in Farmed Sea Bass
Aeration and cannabidiol are not often considered side by side, but a new study on farmed European sea bass suggests they work well together. Over five weeks, researchers tested dietary CBD, modified aeration, and a combination of both. The results were clear: fish in all welfare-promoting groups showed higher survival rates, while the combined treatment offered the strongest boost in stress resilience and growth. This is practical, measurable progress for aquaculture.
