This is a dynamic webpage, new data is constantly being uploaded. Follow our progress on the blog.

This webpage represents data from environmental monitoring of aquaculture in sea cages. Companies that conduct fish farming are by law obligated to do environmental monitoring and which shall be performed by independent company. Doing so a thorough monitoring plan is established and which is approved by the Environmental Agency. During monitoring, both benthic (sediment) - and sea water samples are collected at designated stations (GPS coordinates). Samples are processed and species or groups of animals are identified. By doing that, animal communities can be identified and dynamics of those registered. This webpage shows how individual animals, or groups and communities respond to different organic loads at any given sampling time.

This is a barchart that shows the number of individuals of each species found in the selected sample.

Species Barchart

This is a graph that shows the number of species or the diversity index for a specific area. You can choose which index is used by clicking the buttons in the top right. The X axis shows distance from pens. The currently selected sample shows up thicker on the graph.

Here are sample locations. You can click a point on the map to select a sample. The map shows points from the currently selected date. You can click the toggle to see points from all dates.

Sample selection

Organic load from aquaculture impacts benthic communities of invertebrates. By combining measurements of organic material (TOC, TP, TN and ORP) and the impact these benthic communities, vital information is gained. This information plays a key role in conducting a sustainable aquaculture.

Aquaculture is monitored by changes in chemical composition and the impact on benthic communities of invertebrates.

Fish farming areas

RORUM has for years conducted environmental monitoring for fish farmers, besides being involved in numerous research projects on environmental impact of fish farming. Results are public. However, results are until now, only available in reports that are not very user friendly 😊.    This webpage, as the first of its kind, presents the data in a user friendly way, to allow for everyone to see directly how organic loading from fish farms is measured and how it affects the animal communities in Icelandic fjords.
