“…However, the inclusion of the Zn-amino acid complex (171 μg/kg) for 60 days showed no effects on the growth performance and survival rate of Nile tilapia [54]. Dietary glycine-chelated Zn (B-TRAXIM ® 2C) is another form of organic Zn that was included in the diets of Senegalese Sole (Solea senegalensis) for 60 days without any effect on the growth performance [66].…”

Trace elements are required in optimum regimes for improving the productivity and wellbeing of aquatic animals. Zinc is one of the main microelements involved in several functions in the animal's body. Zinc potentiates the metabolism function, synthesis of essential enzymes, and the formation of hormones associated with growth, reproduction, immunity, and antioxidative roles in aquatic animals. Several sources of zinc are regularly applied in aquaculture, including inorganic, organic, and nanoparticles. Many studies examined the effects of zinc supplementation in the diets of aquatic animals. The results indicated that zinc could be included in aquafeed in a dose-dependent manner. The effects of zinc depend on the dose, source, duration of feeding, animals' sizes, and experimental conditions. This article comprehensively discusses the results of relevant studies that investigated the effects of zinc on the performances of aquatic animals. The review also intended to update the academia with the previous and current status of using zinc in aquafeed. Furthermore, the article includes up-todate outputs of relevant studies of using different zinc sources in aquafeed.

“…As one of the essential mineral elements, manganese (Mn) is involved in maintaining the growth, physiological function, development, and larval survival of fish species [ 1 ]. In addition, Mn is an essential constituent of anti-oxidant enzymes and participates in regulating the metabolism of fatty acids and amino acids [ 2 ].…”

“…The optimal dietary Cu and Fe requirements for post-larval coho salmon are 5.1 mg kg −1 and 101.7 mg kg −1 , respectively, based on the specific growth rate [ 15 , 16 ]. For the crucial role of Mn in fish growth and skeletal development, it is interesting to study trace mineral nutrition in larval and post-larval fish [ 1 ]. Moreover, the signaling of PI3K/AKT/mTOR participates in regulating lipid metabolism and antioxidant capacity [ 17 , 18 , 19 , 20 ].…”

In this study, post-larval coho salmon Oncorhynchus kisutch (initial weight 0.37 ± 0.03 g) were fed with 6 experimental diets with increasing manganese (Mn) content (2.4, 8.5, 14.8, 19.8, 24.6, and 33.7 mg kg−1) for 12 weeks. Our results indicated that the feed conversion rate (FCR), specific growth rate (SGR), condition factor (CF), crude protein, moisture, crude lipid, ash, whole-body Mn, and vertebral Mn were affected by the elevation of Mn content in the diet. The activities of hepatic GSH-PX, Mn-SOD, and CAT were enhanced with increasing Mn content in the diet and reached the highest value at 19.8 mg kg−1 Mn. However, the level of hydrogen peroxide (H2O2), superoxide anion (O2·−), and malondialdehyde (MDA) was reduced with increasing Mn content in the diet. In addition, the activity of hepatic lipase (HL) and lipoprotein lipase (LPL) was increased with the elevation of dietary Mn content and reached a peak value at 14.8 mg kg−1 Mn. The activity of fatty acid synthetase (FAS) and the content of nonesterified fatty acid (NEFA) were increased following the elevation of Mn content from 2.4 to 19.8 mg kg−1 in the diet. The results indicated that the appropriate dietary Mn supplementation improved the feeding efficiency, lipid metabolism, and antioxidant capacity of coho salmon. The dietary Mn requirement for post-larval coho salmon was 17.35 mg kg−1 and 19.75 mg kg−1 based on the SGR and FCR, respectively. An optimal dietary level of Mn enhances hepatic lipid metabolism, and the signaling pathway of PI3K/AKT/mTOR may be involved in regulating the activity of enzymes related to lipid metabolism.
