RESEARCH PROGRESSES OF LIPIDS AND FATTY ACIDS TRANSPORT IN FISH

Vegetable oils have been widely used in aquafeeds because of the shortage of global fish oil resources. However, the excess lipid accumulation in fish has been an increasingly serious problem to fish health. Lipid deposition is a complex process, including lipogenesis, lipid transport and lipolysis. Numerous studies examined effects of vegetable oils replacing fish oil on lipid deposition in fish. by mainly focused on the lipogenesis and lipolysis, little researches were conducted on lipid transport that not only regulates lipid deposition of a specific tissue but also plays a pivotal role in lipid homeostasis and energy balance in organisms. Therefore, this paper reviewed the types and compositions of lipoproteins, lipids and fatty acids transports in fish, and effects of nutritional factors on lipids and fatty acids transport, and proposed the direction of future research.
