“…The concept of nutritional programming has been recently applied for better use of new feeds in aquaculture ( 2 , 9 ) . Because early dietary feeding is a potential window of metabolic plasticity and, therefore, has become the most popular early nutritional intervention, an HC diet during first feeding was provided to Nile tilapia to obtain original data.…”

The present study aimed to investigate nutritional programming of carbohydrate metabolism in Nile tilapia. Early nutritional intervention stimulus was achieved by feeding fry with high-protein/low-carbohydrate (HP/LC) or low-protein/high-carbohydrate (LP/HC) diet since first feeding for 4 weeks, and the effect of nutritional stimulus on carbohydrate and its related metabolism was evaluated through the adult stage. Our findings indicated that at week 1, LP/HC diet-fed fry had lower levels of mRNA for genes coding gluconeogenesis and amino acid catabolism and higher levels of hk2 (P < 0⋅05). As expected, in adult tilapia, although LP/HC diet-fed fish had poorer growth (end of stimulus), the fish showed compensatory growth. There were permanent effects of early high-carbohydrate (HC) intake on several parameters, including (1) modulating hepatic composition, (2) increased muscle glycogen, (3) lower levels of enzymes involved in amino acid catabolism and (4) higher levels of glycolytic enzymes in glycolysis. Finally, HP/LC diet- and LP/HC diet-fed fish were challenged with different dietary carbohydrate levels. Irrespective of challenging diets, the early HC stimulus had significant effects on adult tilapia by (1) promoting utilisation of glucose, which had protein-sparing effects for better growth, (2) inducting lipogenesis and (3) decreasing amino acid catabolism. Taken together, for the first time, we demonstrated that early HC feeding was effective for positive nutritional programming of metabolism in Nile tilapia (an omnivorous fish). It led to the improvement of growth performance in adult fish associated with early feeding, which is linked to a better ability to use glucose, to induce lipogenesis, and to suppress amino acid catabolism.

“…The ratio of phospholipid to sterol (PL:ST) is an indication of membrane fluidity (Drazen et al 2008). Furthermore, the total lipid content and lipid class composition of fish eggs provide important clues to the nutritional requirements of developing embryos and early larvae and possibly the metabolic status of the offspring that grow from the eggs as a result of metabolic or nutritional programming (Hou and Fuiman 2020).…”

Maturation and spawning diets for flatfish broodstock, such as Southern Flounder Paralichthys lethostigma, have received little research attention, despite their critical role in the reproductive performance. During the spawning season, which is when Southern Flounder broodstock produce multiple egg batches, they rely on their diet to supply nutrients to the eggs. Lipids are an important class of nutrients for offspring development. The objective of this brief communication is to describe the changes in egg lipid classes during the spawning season following a diet change. Female broodstock were fed three diets after the first spawn (week 0)—a control diet (equal weights of Spanish Sardines Sardinella aurita and brown shrimp Farfantepenaeus aztecus), a shrimp‐only diet, and a sardine‐only diet (n = 3, 3, and 4, respectively)—for a period of 6 weeks and the lipid composition of the eggs was measured every 2 weeks. The change to a diet of sardines only or shrimp only altered the concentrations of egg lipid classes, indicating that egg composition is affected by maternal dietary intake over a period of 2 weeks or less. Females that were fed the sardine‐only diet produced eggs with higher levels of ketones and acetone‐mobile polar lipids and lower levels of hydrocarbons than did females that were fed shrimp, exhibiting changes that were consistent with the differences between the diets. The shift to the sardine‐only diet had little effect on total lipids, triacylglycerols, free fatty acids, and sterols in the eggs. The change to the shrimp‐only diet resulted in subtle but consistent decreases in all of the lipids, except wax/steryl esters at week 2, followed by gradual increases. This suggests that the shrimp‐only diet provided insufficient nutrition and that the females mobilized stored lipids to compensate. These preliminary results revealed interesting patterns that, with further research, could lead to improved diets and feeding protocols for the production of Southern Flounder.
