The objective of the study was to determine the optimal salinity required to culture fingerlings (juvenile fish) from hatch to weaning under on-farm conditions. Low salinity conditions can affect the early development of the Florida pompano by increasing osmoregulatory stress, which reduces the availability of metabolic energy reserves, otherwise needed for developmental processes such as cellular formation. Results, published in the journal Aquaculture, showed that larvae reared at 10 ppt grew at a normal rate and the developmental stage had a greater impact than salinity on fatty acid composition and larval gene expression. It have shown that it is possible to grow this warm water marine species in salinities a low as 10 parts per thousand, which makes it more economic and easier for producers far from the coast to attempt Florida pompano commercial growth, it expect to run this study for a longer period to investigate the long-term effects of low salinity on larval health and development. An important metric for determining the health and viability of Florida pompano as a commercial food species is the lipid profile of the larvae. Lipids are composed of individual fatty acids, including essential fatty acids (EFAs) such as docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA). In the early days of development, the fatty acids linoleic acid (LA), alpha linoleic acid (LNA), and 18:3 n-6 were proven to be important as potential energy fuels and precursors for long-chain polyunsaturated fatty acids (LC-PUFA) biosynthesis, which was supported by the whole transcriptomics analysis.
