USA.- Land-based management has reduced nutrient discharges; however, many coastal waterbodies remain impaired. Oyster “bioextraction” of nutrients and how oyster aquaculture might complement existing management measures in urban estuaries was examined in Long Island Sound, Connecticut. Eutrophication status, nutrient removal, and ecosystem service values were estimated using eutrophication, circulation, local- and ecosystem-scale models, and an avoided-costs valuation.

Galway, Ireland.- An innovative multidisciplinary aquaculture project led by NUI Galway and Athlone Institute of Technology is set to improve production efficiencies and management of farmed fish at several inland freshwater sites. The project ‘ECOAQUA’ has received €348,781 in funding under the European Maritime Fisheries Fund (EMFF), administered by Bord Iascaigh Mhara, through the Knowledge Gateway Scheme, on behalf of the Department of Agriculture, Food and the Marine.

UK.- Marine diatoms contribute significantly to photosynthesis in our oceans and act as the base of the food chain in many of the most productive fisheries. The process of photosynthesis in phytoplankton is affected by cell size, as the rate at availability of carbon dioxide (CO2) is much lower around large diffusion-limited cells.
