How can we increase the omega-3 content of salmon that are fed sustainable feeds? A brand new map of the salmon’s genome makes it much easier to characterize heritable differences in how well different salmon families utilize the various nutrients.
Salmon farmed on modern feeds contains less of the healthy, long-chain fatty acids (EPA and DHA) than before. Until about 15 years ago, farmed salmon were fed fish oil as a replacement for their omega-3 rich natural prey. However, fish oil is now a scarce resource, and more than half of the fat in modern feeds comes from plant oils that are inexpensive, but devoid of long-chain omega-3 fatty acids. How can we increase the omega-3 content of salmon on sustainable feeds?
GenoSysFat combines genomics and systems biology to improve feeding and breeding for healthy omega-3 in salmon farmed on sustainable feeds.
