Outline• What, how, where, when?• What: From indicators to measurablevariables• How: book of protocols• Where: selection of study sites• When: summer 2006


“What”• Which variables to measure?• Variables were chosen on basis of– data needed for selected indicators andpredictive models– Skills/training needed– dedicated gear & analytical requirements–cost


How to measure?• Need for standardized methods; aEuropean standard• Need for quality control–Precision– Accuracy


Book of Protocols


ECASA Book of Protocols• Selection of sampling stations• Hydrography• Description of the seafloor• Sediment sampling– Grab sampling– Benthos– Macrobenthos– Meiofauna– Phytobenthos• Sediment grain size analysis• Sediment chemistry– Sediment redox potential, Eh– Sediment organic matter– Sediment organic carbon– Total nitrogen in sediment– Inorganic and organic phosphorus insediment• Water column (water quality) sampling• Secchi disk transparency• Dissolved nutrients in seawater– Nitrate/Nitrite in seawater– Orthophosphate in seawater– Ammonium in seawater• Total N & total P in seawater• Particulate matter in seawater– Particulate organic carbon & nitrogen inseawater– Particulate organic phosphorus inseawater• Chlorophyll a determination• Bioassay studies to assess nutrientlevels around aquaculture


“Where”• Study sites – criteria for selecting sitesincluded:– Location– Species– Production level– Gear used


Criteria for Study Site• good representative of EU aquaculture:culture method, species, geographicalfeatures• existing background data• study site is readily accessible frompartner's institute• partner has all necessary field equipmentand lab gear necessary


ECASA Study Sites• Norway - Tromso• Scotland – Loch Creran; Vidlin Voe• France – Baie des Veys; Pertuis Breton• Portugal – Ria Formosa• Spain – Almeria• Italy – Bisceglie; Chioggia• Slovenia – Piran Bay• Croatia – Pakostane• Greece – Cephalonia; Sounio

“When”• Greatest potential impact – summer– Why? Higher temp’s -> metabolic rates,fish growth, feed input, nutrient output,algal growth (eutroph)• ECASA study site sampling focused onsummer 2006
