Intensive fish farming has been dominated by salmon and trout species. We now see a growth of the farming of marine species. Especially in Asia there are a large number of warm water marine species that can be farmed.
Products from Skretting has been delivered to more than 50 species of farmed-raised fish, though many of them still are raised on a more experimental than commercial scale.

8. FEED FOR ALL PURPOSES Broodstock feeds Larval feeds Juvenile feeds
Transfer diets (freshwater to saltwater)
Grower diets
Harvest diets
Anti stress diets
Organic feeds
Speciality feeds (for example Label Rouge)
Customer specific feeds
Certified products (= for supermarket chains)
We also have dedicated production of medicated feeds
It is not only challenging to produce feed to meet the nutritional requirements of a large number of different species of fish, we must also consider that the nutritional needs are dependent upon life stages and the changing environment.
Broodstock is one of the most important, but often overlooked, production stages in fish farming. The yield further down the production chain will be determined to a great extent on the quantity, quality and health of the fry that the broodstock produces. In Skretting we believe broodstock nutrition can often be a neglected area. To ensure healthy and rapid growth of the fish we produce for food, it is of vital importance that the broodstock and subsequently the eggs get the best possible nutritional input.
Juvenile feeds are designed for feeding to larvae and fry of fish after hatching. In the early stages of life the nutritional quality of the feed is essential to ensure healthy and normal development of fry. It is important to produce feed particles for these young fish with the right size and physical quality. It is also important that the feed does not worsen water quality in the fry tanks. Juvenile feeds range from tiny particles of 100 microns in size up to large pellets 3 mm in diameter. Juvenile diets are made with special production equipment to ensure excellent nutritional and physical quality.
Skretting supplies a comprehensive range of on-growing products well suited to feeding fish after the juvenile stage. Our products target different growth rate and feed conversions depending on the production plan and economic consideration of the farmers. The nutritional composition and raw material composition of all our feeds is carefully balanced to deliver the desired carcass quality at harvest. We also strive to formulate our diets so that the impact on the environment is minimised.
Fish live in a natural environment that changes frequently for example, water temperature, water current and dissolved oxygen content. It is important, therefore, that fish are healthy and fit to cope with this changing environment. In specialised diets we add natural ingredients that research has proven stimulate the general health of the fish. So, through nutrition and feeding we can help fish to be healthy and fit to cope with a changing environment.

15. Focus areas in nutrition research
Defining nutritional needs and response
(Protein, amino acids, energy and FAs, vitamins and minerals)
Various species
Various life stages
Various environment (temperature, …)
Raw material values
“New” and existing RMs
Defining quality criteria (Nutrition Processing and food safety)
Digestible nutrient content / Nutritional value
Anti-nutritional factors (max inclusion)
…in various environment (temperature…)

16. Focus areas in nutrition research
Pigmentation of salmonids
Pigment cost about 15% of total feed cost
Evaluation of pigment sources, retention and optimum pigment regime
Functional diets - Feed ingredients that
Strengthen immune system
Support transfer from fresh to salt water
Gut stabilisation ingredients
Harvesting diets

17. It is very much about fish meal and oil substitution

18. Fish oil substitution Status: Minimum 30% FO Challenges:
Max 50% of 1 veg oil source
Challenges:
It is not about FCR, SGR, Texture or Taste
It is not about nutritional needs, when keeping 30% FO
But less knowledge when we come closer to 100% substitution
Need more knowledge in critical phases like smoltification (a.o. cataract)
Research focus:
Know nutritional needs in various life stages, to avoid Production Induced Disorders (PID)
Know how to optimise a limited source of EPA/DHA

19. Fish Meal substitution
Fish Meal substitution is a jigsaw with 4 puzzles:
Availability of concentrated raw materials (>60% protein + fat), and defining their nutritional value.
Understanding digestibility of minerals with high inclusion of veg proteins. To avoid Production Induced Disorders
Knowledge of salmon’s nutritional needs, and market/legal availability of micronutrients
Ensure feed intake /palatability
…. At an acceptable cost

20. Feed production Process ability of new raw materials
Interaction between production and nutrition
New process technology

21. How and Why do ARC work with other research institutions?
20-30% of trials are done outside of own facilities
Why:
Species or environment requirements that make Lerang impossible to use
Flexibility, while our facilities are running “100%”
Special analyses
Competence that we do not have in-house
Ensure that we have a large network with various competencies
Our task is to implement world class know how, not necessary develop it.
Grants
When we want to publicise
But our own researchers stay very much involved, to be able to do the implementation afterwards
