International Workshop on Modelling Environmental Interactions of Mariculture

Third Announcement and Final Call for Papers

The ICES Working Group on Environmental Interactions of Mariculture is organizing a Modelling Workshop which will be held at the Bedford Institute of Oceanography, Dartmouth, Nova Scotia, Canada, 6-8 September 1995, chaired by Drs W. Silvert and B. T. Hargrave of the Habitat Science Division. The objective of the Workshop is to bring together researchers actively involved in the development of models of mariculture interactions in order to identify and compare different approaches to modelling the environmental interactions of mariculture, and to evaluate performance, application and cost-effectiveness of these models. The focus is on finfish interactions in light of the fact that the ICES Shellfish Committee will be organizing a similar meeting in 1996, but some relevant papers dealing with shellfish culture will be included.

The Workshop is centred around models that deal with four topics: Effluents, Dispersal, Effects, and Implementation. These are defined as follows:

Effluents:
Production of particulate and dissolved effluents by cultured marine organisms. These calculations are generally based on physiological models. We hope to reach a consensus on the modelling of effluents from common species such as Atlantic salmon.

Dispersal:
Physical transport of effluents from a farm into the water column and sediments, including processes such as flushing, sedimentation and resuspension.

Effects:
Environmental effects that these wastes generate in the environment, such as changes in primary production due to nutrification and turbidity, or changes in benthic conditions.

Implementation:
Use and presentation of models in a management framework. This can include the use of graphical user interfaces (GUIs) and expert systems, as well as protocols for the use of models in environmental impact assessment for mariculture operations.
It is expected that all participants will be knowledgable about modelling mariculture interactions and will be prepared to participate in and contribute to technical discussions on this topic. The workshop will include quantitative comparison of different models in order to identify any significant discrepancies and to identify under which circumstances each model is applicable.

In order to permit free and frank interaction, the Workshop will be limited to about 30 or 40 active researchers. Based on the responses to date it appears that the number of participants will be close to 30, so there is still space for latecomers. Still, we ask that potential participants make their interest known as soon as possible. Anyone interested in attending should contact the organizing committee at the address below as soon as possible with an indication of what their modelling interests and experience are and whether they are interested in presenting a paper, poster, or demonstration. Early submissions will receive preference in scheduling. We plan to carry out quantitative comparisons of different models during the Workshop, so we are hoping that most of the participants will be able to bring a version in a form that can be run.

The organizers of the Workshop will produce a report in the form of a detailed document that can be used as a basis for future model development. An ICES Theme Session entitled Mariculture: Understanding Environmental Interactions is scheduled for the Annual Meeting in Denmark 21-29 September 1995, and an informal report on the Workshop will be presented at that time. We would also like to publish at least some of the individual presentations from the Workshop, but because we want to cover state-of-the-art techniques including work in progress, we do not intend to go through the processes of peer review and publication in a primary journal, so any such publication would be in the form of a technical report that would come out very soon after the Workshop. We would also like to make as much of the material as possible available over the Internet for use by the international scientific community.
