Effects of nutrient release from Mediterranean fish farms on benthic vegetation in coastal ecosystems

Objective

The objective of this project is to examine effects of nutrients released during fish farming on community dynamics of the benthic vegetation in coastal zones in the Mediterranean.

We wish to obtain new and valuable insight within the following subjects:
- Fate of nutrients released from aquaculture production in the Mediterranean
- Effects of aquaculture on sea-grasses and associated benthic fauna
- Shifts in coastal vegetation communities (from seagrass to macroalgae)
- Seagrasses and fauna as early warning indicators of aquaculture impacts

In general, more than 70% of the total nitrogen and phosphorus added with the food to fish farms is lost to the aquatic environment (6) and is thereby a source for enhanced pelagic primary production.

Very few studies have been able to measure enhanced nutrient concentrations in surroundings of fish farms, suggesting that the nutrients are rapidly incorporated into different components of marine vegetation or exported to the ocean.
