October 7th to 10th, Aquaculture Europe , opens its doors for 3 full days in Berlin. This year the conference will focus on “Our Future Growing from Water” a highly relevant topic with a world-population in constant growth. As a result, we continuously add pressure to our global food systems - leading farms to a ramp up production, in order to keep pace with the growing demand.

Study insight
The development of formulated diets and feeds is essential to increase production of farmed tuna species. Although there is limited knowledge in this area for Pacific Bluefin tuna (Thunnus orientalis) in Japan, no major attempts have been made with Atlantic Bluefin tuna (Thunnus thynnus; ABT). In the present study, two trials were performed using inert formulated diets as juvenile feeds for weaned ABT in order to establish adequate dietary levels of both lipid and omega-3 long-chain polyunsaturated fatty acids (LC-PUFA).
In Trial A, fish fed MGK displayed the highest growth, followed by 15KO, with 20KO displaying the lowest growth although no differences were found in terms of fish survival. Thus, a lipid content of 15% was considered better than 20% for ABT juveniles. In Trial B, fish fed 15KO and 15KORO showed the highest growth in terms of weight and fork length (including weight gain and SGR). Increasing dietary lipid level or adding RO to the feeds did not increase liver lipid content as compared to 15KO.
The liver fatty acid profile largely reflected dietary intake confirming very limited LC-PUFA biosynthetic activity for this teleost species. Consequently, the liver of fish fed 15KO and 20KO displayed the highest contents of docosahexaenoic acid (DHA). The hepatic expression of genes for lipid and fatty acid metabolism, transcription factors, and antioxidant enzymes was investigated with many of the genes showing regulation by both dietary lipid and LC-PUFA contents.
Meet our variety of experts at the booth
Aker BioMarine scientists Tibiabin Benitez-Santana, Director R&D, Fish Nutrition and Kieranpret Kaur, R&D Director Salmonids is ready to answer all questions related to studies and farmed fish physiology – in simple or peer terminology.
In addition, VP QRILL Sales EMEA & Oceania, Kjetil Ribe can assist on commercial aspects and how krill can benefit species in your region.
Marte Dalsegg, Content Manager and Tone Solstad, Marketing Manager, will also be happy to help you with any press and commercial inquiries.
Why Krill?
Krill is a fascinating crustacean. Full of essential nutrients, krill is found at the bottom of the food chain, meaning it consists of a very low contaminant-level. It is a sustainable source of protein, containing omega-3 phospholipids, feed attractants and astaxanthin. Research is key in understanding how, when and where the effects of krill is at its best. Studies are done on a variety of farmed species and krill is used in diets for fish and shrimp all around the world.
