Protect our oceans

Aquaculture

We are committed to responsible and effective management of our aquaculture operations.

Certification

One important tool in the Group’s quality and environmental efforts is certification according to international standards.

Lerøy Seafood Group has been involved in the development of the ASC-standard since 2004. In 2013, Lerøy Seafood Group was the first company worldwide to be certified according to the ASC standard. ASC-certification guarantee that our aquaculture operations are conducted in an environmentally sound and sustainable manner.

The main principles in the ASC standard are:

  • Comprehensive legal compliance
  • Conservation of natural habitat and biodiversity
  • Conservation of water resources
  • Conservation of species diversity and wild population through prevention of escapes
  • Use of feed and other inputs that are sourced responsibly
  • Good animal health (no unnecessary use of antibiotics and chemicals)
  • Social responsibility for workers and communities impacted by farming https://www.asc-aqua.org/
ASC Salmon

Lerøy has chosen to certify its sites in line with the demand from the market for certified fish. Moreover, all sites operate in accordance with the requirements that apply in the ASC-standard.

The aim is to continue the certification process according to the ASC standard.

In 2020, 71% of our biomass in two of our three farming companies was ASC certified.

Global G.A.P

GlobalG.A.P. is a standard for environmental conditions covering the Group’s production activities and the  employees’ working environment. The standard covers the production process from roe stage to fish slaughter.

The main principles in the GLOBALG.A.P. standard are:

  • Food safety: The standard is based on food safety criteria developed from the generic HACCP*
  • Environment: The standard has two parts; one for environmental protection and one for good aqua- culture practice to minimise the negative environ-  mental impact of aquaculture.
  • Employees health, safety and welfare: The stan- dard sets global criteria for workers’ health and safety in the production facilities, and contains  guidelines for social issues.
  • Fish welfare: The standard sets out global criteria for fish welfare in production facilities.
  • HACCP (Hazard Analytical Critical Control Point): Risk analysis containing critical control points. globalgap.org

1) The R&D licences are time-limited with a duration of three years,
from time of project start. The licences have zero purchase price,
and therefore no depreciation. The R&D licence allocated to Lerøy
Aurora in the table above legally belongs to Akvaplan Niva (third
party), but is operated by Lerøy Aurora. The 3 R&D licences allocated
to Lerøy Midt in the table above is attached to a specific project that
ended in March 2021, and is therefore expiered from April 2021.

2) The teaching licences are considered time-limited with a
duration of 10 years. The licences have zero purchase price, and
therefore no depreciation. The teaching licence allocated to Lerøy
Aurora in the table above legally belongs to Troms- og Finnmark
Fylkeskommune (third party), but is operated by Lerøy Aurora.


3) The parent fish licence allocated on Lerøy Aurora in the table
above legally belongs to Lerøy Midt AS (group company), but is
operated by Lerøy Aurora.
For a more detailed explanation of why farming licences are
deemed to have an indefinite useful life and are therefore not
subject to amortisation, please see item (X) in the note on
accounting policies.

 

Innovation through special licenses

Lerøy Seafood Group operates several special production sites/licenses to assure innovation regarding sustainability.

Biodiversity

Minimize our negative impact on marine ecosystems, support its recovery  and help secure biodiversity.

Ecosystem impact

All activities will have a varying level of impact on the environment. The Group's goal is to minimize the environmental footprint of our operations. We only fish species from fish stocks that are appropriately managed, and we constantly strive to find working methods and equipment with minimal footprint.

Our  aim is to avoid harmful impacts on species caused by intervention in the natural environment in fjord systems, including sedimentation/seabed’s.

Main goal: To be able to leave the area where we have our business in the same condition as it was before we started our production.

KPI: Biodiversity

Copper

Copper is a naturally occurring chemical element which can be toxic at high levels in the marine environment. Nets are treated with antifouling agents containing copper. However, cleaning of nets is  necessary to ensure good water quality for the farmed  fish. Lerøy Seafood Group uses low-pressure underwater washers to minimise the risk of copper flaking off.

Projects have been implemented to  measure the amount of copper emissions for each wash. Depending on the results, Lerøy Seafood Group will explore alternative methods for keeping the nets clean. At sites where elevated copper amounts have  been detected in the sediments, the Group has started  to use antifouling agents without copper, or has changed the nets as an alternative to in-situ cleaning.

In addition to cleaning in-situ, all nets are cleaned at onshore sites after each production period. Onshore cleaning sites have zero copper emissions, as required  by Norwegian legislation.

Copper impregnation has a positive effect on sea lice and is used as there are currently no adequate alternatives. The Group is actively working with suppliers to develop an alternative to replace copper.

Main goal: Replace antifouling agents that contain copper

Fallowing

As a strategy to minimize infection pressure and environmental impact, all sites are fallowed and washed/disinfected every two years. In all regions where the Group has operations, fallowing and  stocking periods are coordinated in zones, defined by the The Norwegian Food Safety Authority, NFSA and companies in each Area Based Management, ABM scheme.

Every site in a defined coordinated area is fallowed every second year for at least two  months. Within each area-based management area, there is at least a one-month coordinated fallowing period every second year.

In 2020, every marine site was fallowed for more than four months (138 days) on average for the Group. 

Main goal: Average fallowing per location: Minimum 60 days

Fallowed days in average per site
