Zosteraceae

The distribution of eelgrass spans the coastlines of temperate and tropical zones worldwide. It thrives in shallow, sheltered marine environments such as estuaries and coastal lagoons. These areas provide the necessary light penetration for photosynthesis and the sandy or muddy seafloor conditions that the plant requires to anchor its creeping rhizomes.

Botany-wise, eelgrass is characterized by long, ribbon-like leaves that are highly resilient to tidal currents. The plants are capable of pollination underwater, a rare trait among higher plants. Their morphological structure allows them to optimize nutrient absorption directly from the water column, concentrating vital minerals within their tissues.

Cultivation practices for eelgrass in mariculture require careful environmental management rather than traditional intensive farming. Sites must be shielded from heavy wave action to prevent sediment erosion. Successful management involves monitoring water transparency and ensuring that the concentration of nutrients remains within safe, non-eutrophic levels for optimal plant development.

Regarding хозяйственное (economic) utility, eelgrass is highly valued in various sectors. Its dried biomass serves as a nutrient-dense additive in livestock feed and as a high-quality organic soil conditioner for agriculture. Furthermore, the extracted compound zoosterin is utilized in the food and pharmaceutical industries, and its fibers are used in sustainable bio-based packaging solutions.

• High iodine and mineral content in biomass.
• Natural filtration of water columns.
• Carbon sequestration potential in seagrass meadows.
• Sustainability as a renewable biological resource.
