Aquaculture International · 2025 · Vol. 33 · Issue 6 · Springer
Saccharomyces cerevisiae (SC) has emerged as a promising probiotic in aquafeeds for enhancing fish growth, health and resilience to environmental stressors. This study investigated the physiological, biochemical, histological and molecular effects of dietary SC supplementation in Nile tilapia ( Oreochromis niloticus ), under normal conditions and following glyphosate (GLY) challenge. Ninety fish (7.93 ± 0.026 g) were randomly...

Parasites pose significant challenges to aquaculture and fisheries industries. Our study focuses on the Polyonchobothrium magnum and African catfish to address a potential health issue in aquaculture, explore host–parasite interactions that can help develop effective management practices to ensure fish health and industry sustainability. P. magnum was isolated from the stomach of African catfish ( Clarias gariepinus ) as the p...

The danger posed by waterborne toxicity from herbicides endangers the aquatic ecosystem. Using dietary medicinal herbs is a useful approach to mitigate the effects of herbicide toxicity on aquatic animals. This study attempts to examine the consequences and potential mechanisms behind the dietary addition of horseradish tree ( Moringa oleifera ) leaf extract (MOLE) with the help of phytase addition to check the overall growth...

This study was conducted to explore the effects of dietary inclusion of Chlorella vulgaris (CV) or/and vitamin C (VC) on growth, hemato-biochemical parameters, oxidative and antioxidant status, reproductive hormones, and semen quality variables, and scrotal-testicular dimensions of Zaraibi goat bucks. Twenty sexually mature bucks (41.49 ± 0.91 kg BW) were randomly divided into 4 groups (5 bucks/group). The control group was fe...

In medicine, silver nanoparticles (AgNPs) are employed often. They do, however, have negative impacts, particularly on the reproductive organs. This research aimed to assess AgNP impact on the testis and the possible intracellular mechanisms to induce testicular deteriorations in rats at various concentrations and different time intervals. Sprague Dawley rats ( n = 40) were allocated into four equal groups: the control one, an...

Despite the extraordinary use of silver nanoparticles (AgNPs) in medicinal purposes and the food industry, there is rising worry about potential hazards to human health and the environment. The existing study aims to assess the hepatotoxic effects of different dosages of AgNPs by evaluating hematobiochemical parameters, oxidative stress, liver morphological alterations, immunohistochemical staining, and gene expression to clar...

Ochratoxin A (OTA) is one of the most dangerous and that pollute agricultural products, inducing a variety of toxic effects in humans and animals. The current study explored the protective effect of different concentrations of Aspergillus awamori ( A . awamori ) against OTA (0.3 mg/kg diet) induced renal and cardiac damage by exploring its mechanism of action in 60 New Zealand white male rabbits. Dietary supplementation of A ....

The current study investigated how different fasting and refeeding regimes would impact Nile tilapia growth performance, histopathological examination, and gene expression of myostatin, myogenin, GH , IGF-1 , and NPYa . Nile tilapia fish ( n = 120) were randomly allocated into four groups, including the control group fed on a basal diet for 6 weeks (F6), group A starved for 1 week and then refed for 5 weeks (S1F5), group B sta...
