Key indicators on fish health, biology and harvest

Fish health in focus!

Here you will find and access the most important indicators on future harvest quantities such as fish health, standing biomass, feed sales and smolt release. These are good indicators on medium term and long term harvest. And much much more of course. Enjoy my macro and biology page!

Fish health in MHG’s own words:

MHG writes in their Handbook that salmon is universally acclaimed to be a key part of a healthy diet Norwegian salmon farmers deliver a tasty, nutritious and sustainable product that is enjoyed by five million people around the world everyday.

The UN Food and Agriculture Organisation reports, “Fish is a food of excellent nutritional value, providing high quality protein and a wide variety of vitamins and minerals, including vitamins A and D, phosphorus, magnesium, selenium and iodine in marine fish.”

The presence of these vitamins, minerals and essential fatty acids, makes seafood a healthy choice good for both physical and mental wellbeing and is widely recognised as good nutrition by health authorities, dietary specialists and many others.

Maximising survival and maintaining healthy fish stocks are primarily achieved through good husbandry and health management practices and policies.

Such practices, in addition, reduce exposure to pathogens and the risk of health challenges. The success of good health management practices have been demonstrated on many occasions and have contributed to an overall improvement in the survival of farmed salmonids.

Fish health management plans, veterinary health plans, bio security plans, risk mitigation plans, contingency plans, disinfection procedures, surveillance schemes as well as coordinated and synchronised zone/area management approaches, all support healthy stocks with emphasis on disease prevention.

For the majority of salmonid health conditions, prevention is achieved through vaccination at an early stage in production. Vaccines are widely used commercially to reduce the risk of health challenges. With the introduction of vaccines a considerable number of bacterial health challenges have been effectively controlled, with the additional benefit that the quantity of medicine prescribed in the industry has been minimised.

In some situations however medicinal treatment is still required to maximise survival and even the best managed farms may use medicines from time to time. For several of the viral diseases, no effective vaccines are currently available.

  1. And I would like to know the Omega 3 content in the farmed salmon vs the wild ones. And medicines….. as no vaccinations….. hmm… Not too sure about eating this fish anymore.
