The results from the Icelandic marine monitoring activities in 2020 on undesirable substances in seafood have been made available in an online report. The monitoring has been an ongoing project since 2003 and Matis ohf. collects and disseminates the data.

The main aim of this project is to gather data and evaluate the status of Icelandic seafood products in terms of undesirable substances and to utilise the data to estimate the exposure of consumers to these substances from Icelandic seafood and risks related to public health.

The results show that in regard to the maximum levels set in the regulation, the edible parts of Icelandic seafood products contain negligible amounts of dioxins, dioxin like and non-dioxin-like PCBs. In fact, all samples of seafood analysed in 2020 were below EC maximum levels.

Can the inclusion of seaweed in cattle feed affect the meat and milk?

The SeaCH4NGE project aims at addressing this.

The University of Reading has recently finished two feeding trials, one with dairy cows and another with beef cattle. Currently Matís personnel is in full force preparing and analysing the chemical and nutrient content of the meat and milk.

Additionally, the products will undergo sensory and texture analysis to investigate whether seaweed in the feed can affect these attributes. The University of Reading has already carried out sensory analysis of the dairy products where first results indicate that astute consumers might be able to taste the difference if these products were to enter the market. The remaining question is – will the trained sensory panel at Matís taste a difference of the meat?

With the project coming to an end soon the SeaCH4NGE research team is looking forward to compiling and scrutinising all the results from the project.

Below are some pictures from the research process.

Matís aquaculture research station : MARS

Matís runs a top-of-the line aquaculture research station in Reykjavík, which is called MARS (Matís Aquaculture Research Station).

In MARS we have facilities and expertise to produce aquaculture feed and to test it in one of our three aquaculture systems. These systems consist of two RAS systems (Recirculation Aquaculture System) and one flow-through system.

  • RAS 1 consists of 36 tanks that each take about 200 liters of water/seawater.
  • RAS 2 consists of 24 tanks that each take about 800 liters of water/seawater.
  • The flow-through system consists of 48 tanks that each take about 20 liters of water.

In MARS we develop and produce feed, some of which is produced from new-novel proteins. We then run growth- and/or digestibility trials to test the different characteristics of the feed.

There is also great demand from international feed- and aquaculture producers to use our facilities and expertise, as they contract Matís to produce feed from raw materials they provide, and test them in our aquaculture systems. We work with different species and sizes of fish in MARS, including Atlantic salmon, tilapia, arctic char, rainbow trout, whiteleg shrimp and oysters.

There are only a handful of research stations that can offer the same kind of facilities and expertise as we can, when it comes to feed development and aquaculture trials. In addition there are many links with different departments of Matís that make us quite unique when it comes to “offering a wholistic package” for the aquaculture industry and research community e.g. chemical analysis, microbiology, sensory analysis, product development, processing, packaging, logistics, traceability etc.    

There is a great demand for our services in MARS and we are optimistic about a bright future for Aquaculture.
