aquaculture-welfare
Aquaculture welfare refers to the practices and standards that ensure the health and wellbeing of organisms raised in aquatic farming systems, including the aquatic plants and algae that form the foundation of these ecosystems. In plant science, understanding how aquatic plants respond to stressors in managed water environments—such as nutrient fluctuations, water quality changes, and cultivation density—is essential for optimizing their growth and productivity. Research in this area informs sustainable aquatic plant cultivation, with applications ranging from food production to bioremediation and ecosystem restoration.

Adding simple physical structures like gravel or rubber cords to fish tanks can boost the immune system of farmed rainbow trout, with rubber cord 'plants' proving especially effective at protecting fish health under crowded conditions.
Rubber cord enrichment significantly boosted immune activity (respiratory burst, peroxidase content, and lysozyme) in trout under double stocking density (p < 0.05)
Gravel substrate increased social interactions and triggered signs of inflammatory immune activation in head kidney immune cells
A negative correlation between cortisol and body size suggested social hierarchy formation, indicating behavioral changes driven by environmental enrichment
