“…The basic weaning diet was developed using standard feed ingredients according to El-Dahhar et al (2021). Briefly, the ingredients (Table 1) were milled through a screen (0.6 mm holes diameter) before mixing, then homogenized well in a food grinder (model 5 NFGA; Kitch-enAid, St. Joseph, MI 49085, USA).…”

To sustain normal development, high survival, and rapid growth, marine fish larvae require a diet rich in polyunsaturated fatty acids, which could decrease the risk of reactive oxygen species accumulations. Consequently, a 60-day feeding experiment was conducted to determine the effect of silymarin (SM) supplementation in weaning diets on the growth performance, survival, antioxidant enzyme activities, and fatty acids profile of European seabass (Dicentrarchus labrax) larvae. Four isonitrogenous and isolipidic diets were investigated using SM at levels of 0, 200, 400, and 600 mg kg−1 (SM0.00, SM200, SM400, and SM600, respectively). The findings showed that, in a dose-dependent manner, increasing dietary levels of SM enhanced survival, growth, and feed utilization. In the SM600 group, the weight gain, survival, and feed conversion ratio (FCR) improved by 123.21, 11.66, and 38.72%, respectively, compared to the control group. The dose-response analysis demonstrated a strong positive correlation (R2=0.96) between SM levels and weight increase, and a strong negative correlation (R2=0.88) between SM levels and FCR. The antioxidant enzyme activities of larvae given SM-enriched diets were significantly greater than those of the control group. Compared to the control group, the CAT and SOD improved by 81.77 and 5.08 % in the SM600 group. In addition, the saturated fatty acid content reduced while the unsaturated fatty acid content increased, particularly in the SM600 group. The results indicate that supplementing the micro diet of European seabass larvae during weaning with SM at a dose of 600 mg kg-1 increases growth, survival, antioxidant status, and fatty acid profiles.

“…Of course, the morphogenesis and physiology of larval digestive tract might be affected by the cofeeding method [2]. In addition, in confirmation of this issue, it has been reported that the early use of MD can cause detrimental effect on fish growth performance and survival [7]. When the sturgeon larvae start exogenous feeding, their digestive system and enzymes are ready and they are anatomically complete [8,11].…”

“…The type of feeding regimes (FR) for rearing fish larvae is a fundamental problem and determining feeding protocols based on the state of the larvae's digestive system is a vital issue [7]. Changing the type of feed is a critical issue and the best feeding strategy is to pay attention to several parameters (growth, survival, size, and quality) that directly affect the fingerlings in the during the growth period [8].…”

Six different feeding regimes (FR) were tested from 7 to 38 days post hatching (dph). Five thousand four hundred larvae (7 dph, 0.048 g) were randomly stocked in 18 fiberglass tanks contained 100 L fresh water (300 larvae per each tank). In larvae fed with FR-B, includes Artemia nauplii (AN) + Artemia biomass (AB) + microdiet (MD), the body weight (BW) at the end of trail (38 dph) similar the FR-D (AN + CHL + AB + MD), and E (AN + CHL + AB), was at high level. Survival rate was higher in larvae fed FR-A includes AN + chironomid larvae (CHL) + MD, but had a lower BW ( p < 0.05 ). Moderate BW and survival rate were detected in larvae fed FR-C (AN + DP + MD). Larvae fed only MD (FR-F), had the lowest survival and the highest BW ( p < 0.05 ). Different FR had a significant effect on crude protein (CP), crude fat (CF), ash, and dry weight ( p < 0.05 ). The larvae fed FR-C and D had the highest CP ( p < 0.05 ). The highest CF and ash in larvae were detected in FR-F and C, respectively ( p < 0.05 ). Larvae from FR-A and B had higher levels of n−3 long chain polyunsaturated fatty acids in comparison with others FR ( p < 0.05 ). The use of AB and CHL can increased the weight and survival rate of larvae, respectively. At the end of trail, the activity of pepsin, trypsin, lipase and α-amylase enzyme levels were lower in FR-B and F than others FR. Totally, by using a combination of AN + CHL + AB + MD had better results than others and ordered to H. huso larvae feeding. Using MD alone, can cause lesser development of the digestive system and little attractiveness, therefore it can cause starvation, and the empty digestive tract of larvae.
