sustainable-aquaculture
Sustainable aquaculture integrates plant-based systems—such as aquatic macrophytes, algae, and constructed wetland vegetation—to naturally filter nutrients and support balanced aquatic ecosystems. For plant scientists, this field offers insights into how aquatic and semi-aquatic plants absorb excess nitrogen and phosphorus, informing research on nutrient cycling, phytoremediation, and the cultivation of economically valuable aquatic flora.

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
