TLDR
Feed intake, protein efficiency ratio, body composition and economic profitability were not influenced by the amount of soybean oil in the diets, but muscle fatty acid composition differed with diets.Abstract:
A 309 days feeding experiment was carried out on gilthead sea bream fingerlings (initial weight 14.7±4.4 g) to evaluate effects of substitution of fish oil with soybean oil in diets on growth and sensory characteristics and muscle fatty acid composition. Duplicate groups of fish were hand fed with four isoenergetic and isonitrogenous diets (46% protein, 14% lipid and 22 MJ kg⁻¹) in which 0%, 24%, 48% or 72% of the fish oil was replaced by soybean oil. Fish fed diet 72% reached a lower final weight (324 g) than fish fed diets 0%, 24% and 48% (349, 343 and 338 g respectively). Feed intake, protein efficiency ratio, body composition and economic profitability were not influenced by the amount of soybean oil in the diets, but muscle fatty acid composition differed with diets. Panellists observed significant sensory differences between fish fed diet 0% and diet 72%. These results verified the possibility of feeding sea bream until they reached commercial weight with a 48% dietary substitution of fish oil for soybean oil.read more

TL;DR: In this paper, the effects of long term feeding (6 months) of commercial diets with low fish meal content and high levels of vegetable oils (69% fish oil substitution level) were determined in gilthead sea bream (110 grams).

Replacing fishmeal and fish oil in industrial aquafeeds for carnivorous fish
TL;DR: There is potential for significant sparing of FM and FO in carnivorous fish diets during the grow-out phase without affecting fish performance and animal health, and more research is required to evaluate the effects of simultaneous replacement of FMand FO in the diet.

Benefits of fish oil replacement by plant originated oils in compounded fish feeds. A review
TL;DR: Over the past few years, significant breakthroughs have occurred in the replacement of fish oil with plant oils in compounded fish feeds in order to reduce dependence on fish oil as well as reduce costs.

Effects of replacement of dietary fish oil by soybean oil on growth performance and liver biochemical composition in juvenile black seabream, Acanthopagrus schlegeli
TL;DR: The results indicated that the inclusion of soybean oil increased the hepatic α-tocopherol content and reduced lipid peroxidation in fish, however, complete substitution of fish oil with soybeanOil reduced growth efficiency.

TL;DR: Overall, up to 50% of FM protein can be replaced by MBM protein in diets for gilthead seabream juveniles, without compromising growth performance, feed utilization, and nutrient retention.

A simple method for the isolation and purification of total lipides from animal tissues.
TL;DR: In this paper, the authors described a simplified version of the method and reported the results of a study of its application to different tissues, including the efficiency of the washing procedure in terms of the removal from tissue lipides of some non-lipide substances of special biochemical interest.

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.

Strategies for further development of aquatic feeds.
TL;DR: A wholesome approach to culturing fish would be to use appropriate feeding standards that are aimed not only at improving economic returns but also at developing a lasting cohabitation of sustainable aquaculture and a cleaner environment.

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.
