Frequently asked questions

Will rising temperatures pose problems for fish farming?

 

Answer: With rising sea temperatures, bacteria, vira and parasites which have not previously been able to survive in the Danish aquatic environment will now be able to settle and will cause problems for fish and fish farmers. Traditional fish farms, where water exchange in the breeding basins is based on water from watercourses, may compensate for higher temperatures in basins by exchanging greater volumes of water. More modern systems of fish farming, which use water recirculation technologies, may lower the temperature with cooling towers.

Will new bacteria be a threat to food safety?

 

Answer: Higher temperatures could introduce new types of pathogenic bacteria and poisonous algae, which could pose a threat to wild fish and shellfish stocks and eventually to human food safety as well.

Will there be a need to refit fishing vessels?

 

Answer: If the traditional fish species disappear and are replaced by new species, vessels and gear will have to be re-rigged and refitted for the new species. Rising temperatures could also make it necessary to change the way fish catches are stored onboard vessels. Sea temperatures vary considerably even today, so that the summer months, for example, require special cooling measures onboard vessels to enable effective and rapid cooling of the catch straight from the net.
