TL;DR: It is deduced that differences in essential fatty acid requirements for different species of fish reflect different dietary and metabolic adaptations to different habitats and how such knowledge can be exploited to develop improved diets for fish, especially in their early stages of development.

TL;DR: The ideal marine fish larval diet is one containing circa 10% of the dry weight as n −3 HUFA-rich, marine phospholipids with less than 5% triacylglycerols, as exemplified by the lipid compositions of marine fish egg yolk, marine fish larvae themselves and their natural zooplankton prey.

TL;DR: RO can be used successfully as a substitute for fish oil in the culture of Atlantic salmon in sea water although at levels of RO >50% of dietary lipid, substantial reductions occur in muscle 20:5(n-3), 22:6( n-3) and the (n- 3)/(n -6) polyunsaturated fatty acid (PUFA) ratio, which will result in reduced availability of the ( n- 3) highly unsaturated fatty acids that are beneficial for human

TL;DR: The results will undoubtedly emphasise why this ubiquitous HUFA cannot be underestimated in fish nutrition and already the potential benefits to fish physiology and biochemistry of optimising the ARA nutrition of fish are becoming clear.

TL;DR: It is suggested that PO can be used successfully as a substitute for FO in the culture of Atlantic salmon in sea water, however, at levels of PO inclusion above 50% of dietary lipid, significant reductions in muscle 20:5-3, 22:6-3 and the (n-3):(n-6) PUFA ratio occur, resulting in reduced availability of these essential ( n-3) highly unsaturated fatty acids to the consumer.
