Impact of different dietary lipid sources on growth, lipid digestibility, tissue fatty acid composition and histology of rainbow trout, Oncorhynchus mykiss
TLDR
The present results suggest that most of the fish oil can be replaced by the alternative sources tested without compromising growth and feed utilisation, but the histological changes observed suggest an impact of dietary lipid source on the transport and/or metabolism of fat in the fish.About:

Fish oil replacement in finfish nutrition
TL;DR: This review attempts to compile all principal information available regarding the effects of fish oil replacement for the diets of farmed finfish, analysing the findings using a comparative approach among different cultured fish species.

Dietary lipid sources for seabream and seabass: growth performance, tissue composition and flesh quality
TL;DR: The results show that, providing a minimum content of essential fatty acids in the diet, it is possible to replace up to 60% of the fish oil by SO, LO and RO or a mixture of them in diets for seabream and seabass, without compromising fish growth.

Effect of dietary flaxseed oil level on the growth performance and fatty acid composition of fingerlings of rainbow trout, Oncorhynchus mykiss
TL;DR: Results indicate the fingerlings of rainbow trout can be reared on diets in which FO has been replaced with FxO, with no significant effects on fish performance.

Alterations in fillet fatty acid profile and flesh quality in gilthead seabream (Sparus aurata) fed vegetable oils for a long term period. Recovery of fatty acid profiles by fish oil feeding

TL;DR: Results showed that substitution by vegetable oils of up to 60% fish oil in diets for gilthead seabream does not affect growth and feed utilization even after a long feeding period, however, 80% substitution of fish oil significantly reduced growth.

Lipid nutrition in fish
TL;DR: Results of studies on the energy requirements of fish during recent years have indicated that in the carnivorous fish such as rainbow trout, eel, yellowtail and plaice which have limited ability to utilize carbohydrates of high mol, dietary lipids play an important role in this respect and have a sparing action on dietary protein.

Digestibility determination in fish using chromic oxide marking and analysis of contents from different segments of the gastrointestinal tract
TL;DR: It was concluded that absorption occurs in all parts of the alimentary tract, and that it is important to limit the stripping of faeces for analysis in digestibility studies to the hindmost part of rectum, i.e. from the ventral fin to anus.

Fatty acid metabolism in freshwater fish with particular reference to polyunsaturated fatty acids
TL;DR: Freshwater fish can desaturate endogenously-synthesized fatty acids to monounsaturated fatty acids via a delta 9 desaturase but lack the necessary enzymes for complete de novo synthesis of polyuns saturated fatty acids which must therefore be obtained preformed from the diet.
