This study investigated how dietary myo-inositol affects osmoregulation, carbohydrate and lipid metabolism, immunity, and antioxidant properties in Penaeus vannamei under long-term low-salinity conditions. A two-factor (2 × 3) orthogonal approach was used with three different concentrations of dietary myo-inositol (0, 1,200, and 2,000 mg/kg) at two dietary carbohydrate levels: normal carbohydrate or high carbohydrate (HC). Six experimental diets […]

The study of fish larval nutrition is important as dietary requirements change significantly with growth. Vieja zonata is a cichlid species that is endemic to Mexico. In this study, we investigated the ingestion rate, prey selectivity, and growth of V. zonata larvae that were fed on prey cultured with and without probiotics. We conducted three

The objective of this research was to investigate how dietary antimicrobial peptides (AMP), namely, Isalo scorpion cytotoxic peptide (IsCT), affect the gill physical barrier function and immune function of grass carp challenged with Flavobacterium columnare (F. columnare). Five hundred forty grass carp were randomly allocated to six groups and fed to varying levels of IsCT

This study was conducted to estimate dietary valine (Val) requirement for juvenile olive flounder (Paralichthys olivaceus). In a feeding trial, a total of 540 fish (initial body weight: 23.0 ± 0.2 g) were stocked into 18 tanks (210 L). Six experimental diets containing graded levels of Val (4, 8, 12, 16, 20, and 24 g/kg, dry matter basis) were fed

The razor clam Sinonovacula constricta, a commercially important and nutritionally valuable bivalve species, has been found to display notable responses to different light spectra. While previous research has highlighted the influence of light spectra on the growth, feeding rate, and various physiological characteristics of S. constricta, its impact on the biochemical composition of this species

Pikeperch (Sander lucioperca) is a species with great potential for aquaculture in Eurasian countries, while feed costs limit the scale of pikeperch farming. Adding carbohydrates to the feed as an energy source is a viable approach to reduce costs and to improve the culture status of pikeperch. In this study, in order to determine the

Palm oil, with its higher production, lower prices, and higher levels of palmitic acid and oleic acid, may have great potential for use in the aquafeed industry. In this study, with an 8-week feeding experiment, the efficacy of palm oil as a substitute for fish oil in tiger puffer feeds was comprehensively evaluated. The control

In the present study, we investigated the effect of dietary supplementation with the probiotic Bacillus amyloliquefaciens AV5 (OR647358) on the growth, serum and mucus immune responses, metabolomics, and lipid metabolism of Oreochromis niloticus. Fishes (27.2 ± 1.7 g and 9.0 ± 1.2 cm) were fed three distinct meals: a commercial diet (control-GC) and two treatment diets supplemented with probiotics at 106

To further explore the impact of nutrient fortification on the ovarian secondary development of redclaw crayfish, four groups were set up: group ①, no feeding; group ②, formulated feeding; groups ③ and ④, formulated feed + nutrient bait. Results showed (1) the proportions of egg-bearing shrimp in groups ③ and ④. 2) The weight growth rate of

The present study assessed the effects of dietary yeast, Saccharomyces cerevisiae, and costmary, Tanacetum balsamita, essential oil on growth performance, biochemical parameters, and disease resistance of Nile tilapia, Oreochromis niloticus. Four diets containing 1 g/kg yeast (Sc), 0.1 g/kg costmary essential oil (Tb), 1 g/kg yeast + 0.1 g/kg costmary essential oil (Sc + Tb), and without Sc and Tb (control) were formulated
