Reformulating aquaculture feeds, an industrywide initiative to reduce dependence on wild fish, has changed farmed salmon’s nutritional profile, as BBC News reported recently. The researchers on whose work the report was based say of course it has, yet it remains one of the best sources for these crucial fatty acids.

Fish oil sparing has proven difficult for fish species, like sea bass, that require the long-chain polyunsaturated fatty acids (LC-PUFAs) abundant in fish oil but lacking in most alternative fats and oils used in aquafeeds.

Low-input culture practices for freshwater prawns can manage their growth and biological characteristics so they can be fed no fishmeal or fish oil.

The authors evaluated graded substitution of fish oil with soybean oil in feeds for juvenile cobia and found a substantial amount of dietary fish oil can be spared without sacrificing production performance.
