Since 2005 it has been mandatory for all fish farms in the sea to carry out trend monitoring of the environment. This monitoring shall meet the requirements set out in NS 9410 (Norwegian Standard) and shall be performed by a competent sours that can document professional competence and which is independent of the principal. The inspections have been developed to have a standard monitoring of areas around aquaculture plants. By monitoring the environment around fish farms, we can ensure that neither surrounding areas or farmed fish are deteriorated. This is crucial for optimizing areas and locations. MOM-inspections are divided into two classes: B and C. 

MOM-B inspection

To perform a MOM-B inspection, a small pinch are used to retrieve samples of the seabed sediment. This is done at least 10 different points under the location. Pinch is used because the samples should be evaluated according to several different sensory parameters such as odor, volume, color, texture, and chemical parameters such as pH and Eh (redox potential), as well as soil type / sediment (geological) and bivalve composition (biological). The inspection provides a qualitative description of the condition of the bottom sediment based on three main categories: Presence of fauna, chemical and sensory state. The sum from the main categories gives a location's status from "very good" to "very bad" (1-4), where state 4 is considered as overload. The survey will be conducted at certain times based on the results of the previous trend monitoring. Monitoring is risk-based in such a way that poor condition leads to more frequent site investigations.

Fisheries Directorate's map tool

Using the Fisheries Directorate's map tools, you can look at the environmental status of all breeding sites along the Norwegian coast. This tool is open to all

 ( ).

Based on the Fisheries Directorate's map tool, you can see that all of Salak's locations have the "very good" or "good" state class (Condition 1 or 2).

MOM C-inspection

The C-inspection is a more extensive seabed study, where the seabed condition from the plant (plant zone) and beyond the recipient (transition zone) is measured. The purpose is to assess the extent of impact from the aquaculture plant. The survey measures the sediment's chemistry and composition, pond fauna and more, to assess whether organic material is from the aquaculture plant or other sources in the area. The C-survey shall be conducted in accordance with the Norwegian Standard.
