Termed the "lungs of the sea," seagrasses are vital to maintaining a healthy underwater ecosystem. They convert carbon dioxide into oxygen through photosynthesis and absorb nutrients, thereby improving overall water quality. Seagrasses also provide an ideal environment for fish sheltering and breeding.
Some forms of aquaculture lead to rapid accumulation of organic matter, including uneaten feed and fish feces, which can alter sediment characteristics. This can affect the root systems of seagrass and Posidonia, potentially leading to changes in nutrient uptake and root oxygenation. Excessive sedimentation can smother these plants, hindering their growth or even causing them to die off.
Degradation of these seagrass beds can lead to reduced biodiversity and altered ecosystem dynamics.
