Peter Strain

EFFECTS (continued)

"Benthic effects of fish cage farming in the Gulf of Aqaba, Red Sea"
Dror Angel, Peter Krost, and Bill Silvert

"Test of a model that predicts benthic impact of salmon net-pen aquaculture"

"Decision analysis"
Juhani Kettunen

Round-table discussion of how the modeling work discussed can best be integrated with management and the decision-making process. A volunteer from each country commented from the perspective of that country's regulatory practices.

The final item on the agenda was discussion of recommendations to the ICES Working Group on Environmental Interactions of Mariculture.
