“…As the ammonia concentration increased, the ALT and AST enzyme activities in the DS group were significantly higher than the SCD group. These results are consistent with the reported findings involving Oreochromis nilotica and Epinephelus (Khieokhajonkhet et al, 2021;Zou et al, 2019).…”

Ammonia is a major environmental pollutant in the aquatic system that poses a great threat to the health of shrimp. Macrobrachium nipponense, as one of the large‐yield farmed shrimp, is facing germplasm degradation. Genetic improvement through hybridization is one of the effective methods to solve this problem. However, there are few studies on the effects of ammonia nitrogen on the germplasm resources of M. nipponense. In this study, the broodstock populations (Dianshan, DS) and hybrid offspring (DS ♀ × CD [Changjiang, CJ ♂ × Dongting, DT ♀], SCD) were exposed to 0, 5, or 20 mg/L of ammonia for 96 h. The survival rate of the SCD group was greater than the DS group, although there were no significant differences in weight gain rate and length gain rate (p > 0.05). The number of positive cells and apoptosis rates in the DS group were significantly greater than in the SCD group after ammonia exposure (p < 0.05). As the ammonia concentration increased, the antioxidant enzyme activities in the SCD group were significantly higher than DS group, while the hepatotoxicity enzyme activities in the SCD group were significantly lower than DS group (p < 0.05). The trends in the expression of antioxidant‐ and immune‐related genes were generally consistent with the activities of antioxidant enzymes. Our study found that the hybrid population had stronger stress resistance than their parent populations at the same ammonia concentration. This study confirms our speculation that hybrid population has a greater advantage in antioxidant immunity, which also provides reference for the follow‐up study of chronic ammonia toxicity.

“…In recent years, many studies have shown positive results in the total or partial replacement of SBM with various plant ingredients in the diet of different sh species, including tilapia (Fadel et al 2017;Khieokhajonkhet et al 2021;Pradhan et al 2020). In this research, the results of the feeding trial indicate that PM150 and SH can be incorporated (in replacement of SBM) into a feed for tilapia juveniles without affecting their performance.…”

Soybean meal (SBM) is the most widely employed vegetable ingredient in aquafeeds, but its rising price and the negative environmental impacts of its cultivation open research efforts for its replacement. More sustainable aquaculture may be achieved by utilizing agricultural and fishery by-products; thus, this study aims to incorporate pea meal (PM) and shrimp protein hydrolysate (SH) as protein ingredients in tilapia juveniles’ feed. The presence of protease inhibitors and the in vitro digestion were evaluated for raw (PM0) and extruded pea meals (PM150), while SH characteristics were studied as well. The nutritional quality of alternative ingredients was assessed to formulate a diet that meets tilapia juveniles’ requirements, and its effects on growth were evaluated. Extrusion significantly reduced the PM inhibitory effect on tilapia proteases (from 5.4–1.9%). In vitro protein digestion of PM150 (7.8 ± 1.35%) did not differ from the control treatment with fish meal (FM; 11.8 ± 1.94%). Additionally, SH presented 41.6 ± 2.91% of DPPH radical scavenging activity. Tilapias fed with a diet where SBM was totally replaced by the dietary inclusion of 25% PM150 and 10% SH, presented comparable growth indicators to those exposed to the control diet. Extrusion reduced PM proteolytic inhibitory effect and improved protein digestibility. SH presented antioxidant effect, as well as, provided flavor enhancers and essential amino acids to the diet. It is feasible to achieve a sustainable dietary formulation for juvenile tilapia using the evaluated by-products without affecting its growth performance.

“…Aquaculture is the fastest-growing farmed food sector and will soon become the main sh and shell sh source for human consumption. The over-demand and rising prices of sh meal (FM), a primary dietary protein source of aquafeeds, have generated the need to nd alternative protein sources (El-Sayed et al 2000; Khieokhajonkhet et al 2021). This demand was mostly covered by soybean meal (SBM), which has become the most widely used protein source to replace FM for n sh diets (Khieokhajonkhet et al 2021).…”
