Despite considerable progress in recent years, many questions regarding fish larval nutrition remain largely unanswered, and several research avenues remain open. A holistic understanding of the supply line of nutrients is important for developing diets for use in larval culture and for the adaptation of rearing conditions that meet the larval requirements for the optimal presentation of food organisms and/or microdiets. The aim of the present review is to revise the state of the art and to pinpoint the gaps in knowledge regarding larval nutritional requirements, the nutritional value of live feeds and challenges and opportunities in the development of formulated larval diets.

“…Furthermore, deformation can negatively impact fish growth, survival, swimming, food conversion, and susceptibility to stress and pathogens (Andrades et al 1996;Koumoundourous et al 1997;Boglione et al 2001). Though the rearing environment (e.g., temperature, salinity, water current, dissolved oxygen, and tank color) (Koumoundouros et al 1999(Koumoundouros et al , 2001Hattori et al 2004;Sfakianakis et al 2004;Okamoto et al 2009;Georgakopoulou et al 2010;Owen et al 2012), genetic factors (Ferguson and Danzmann 1998;Castro et al 2007;Ma et al 2014c), parasites and pesticides (Kusuda and Sugiyama 1981;Liang et al 2012;Liu et al 2012) can affect fish bone development, more and more evidence has demonstrated that nutritional factors during larval fish rearing can directly cause fish deformity (Andrades et al 1996;Afonso et al 2000;Cahu et al 2003a;Sandel et al 2010).…”

The retinoid X receptors (RXRs) are involved in the skeletal development and other biological process such as blood vessel formation and metabolism. Partial sequences of RXRα and β genes were obtained, and their expressions were quantified on golden pompano Trachinotus ovatus at 28 days post hatching (DPH) to explore the molecular response to nutritional manipulation in fish larvae. As live food, Artemia nauplii were separately enriched with Nannochloropsis and Algamac 3080 and non-enriched Artemia nauplii (control) for fish feeding. The expressions of RXRs were detected in the embryos and fish larvae at early stages, suggesting that the skeletal development in golden pompano initiated before yolk re-sorption completion. Fish fed non-enriched Artemia nauplii ended up with higher jaw malformation. The highest specific growth rate was obtained when fish were fed with the Artemia nauplii enriched with Algamac 3080, and the lowest growth rate was observed when fish were fed with unenriched Artemia nauplii. The highest survival was obtained when fish were fed with non-enriched or Nannochloropsis-enriched Artemia nauplii. This study indicates that the use of enriched formula for Artemia nauplii can significantly affect the expression levels of RXRs and jaw malformation of golden pompano larvae, but there is no clear correlation between RXRs expressions and malformation rates when fish are subjected to nutrient challenge.

“…In addition to the importance of meeting essential fatty acid requirements and the potential influence of dietary SFA versus C 18 PUFA content, the availability of phospholipid may determine, in part, the success of fish oil sparing. Phospholipid intake is known to be critically important in successful completion of early ontogeny in fish (Tocher et al 2008;Cahu et al 2009) and likely has a continuing importance in the diet of rapidly growing fish (Seoka et al 2008;Sandel et al 2010;Hansen et al 2011), including Cobia (Trushenski et al, in press). As dietary fish oil and fish meal are replaced with plant-derived lipids and lipid-extracted protein meals, phospholipid may emerge as an essential element of lipid nutrition of o(n-growing fish and an increasingly important factor in aquafeed manufacturing (Tocher et al 2008).…”

Saturated Fatty Acids Limit the Effects of Replacing Fish Oil with Soybean Oil with or without Phospholipid Supplementation in Feeds for Juvenile Cobia

et al. 2013

The high cost and limited availability of fish oil makes plant‐derived lipids attractive for aquafeed manufacturing, but replacing fish oil with these lipids can result in long‐chain polyunsaturated fatty acid (LC‐PUFA) deficiencies. Fatty acid metabolism, specifically the efficiency of LC‐PUFA utilization, may be influenced by the dietary saturated fatty acid (SFA) content versus that of C18 polyunsaturated fatty acids (PUFAs). We assessed the growth and tissue composition of Cobia Rachycentron canadum (55.3 ± 0.2 g initial weight [mean ± SE]; 10 fish/tank, 3 tanks/diet) fed diets (∼49% protein, ∼10% lipid) containing fish oil; 22:6(n‐3)–amended standard, partially hydrogenated, or fully hydrogenated soybean oil; and these same soybean oils supplemented with soybean lecithin for 8 weeks. Although survival (range = 97–100%), final weight (160–189 g), and feed conversion ratio (1.40–1.52) were unaffected by diet, differences were observed in weight gain (185–241%), specific growth rate (1.87–2.19% body weight/d), and feed intake (2.94–3.44% body weight/d). Significant effects of soybean oil type on final weight, weight gain, feed conversion ratio, specific growth rate, and feed intake were noted, with standard soybean oil generally outperforming the other soybean lipids when oil types were pooled across phospholipid supplementation treatments, whereas phospholipid supplementation had no significant effect on any of the performance measures. Differences in dietary fatty acid profile yielded differences in tissue composition. Feeding standard soybean oil resulted in the most greatly modified profiles, whereas the profiles of fish fed fully hydrogenated, completely saturated soybean oil were most similar to those of the fish oil–fed fish. The magnitude of profile change was greatest in the liver and fillet tissues and smallest in the eye and brain tissues. Although further research is necessary to demonstrate whether SFA‐rich lipids can effectively reduce the LC‐PUFA requirements of Cobia, it is clear that SFA‐rich oils offer a strategic advantage in minimizing the effects of fish oil replacement on tissue fatty acid profile.
