Aquaculture International, Journal Year: 2024, Volume and Issue: 32(6), P. 7929 - 7951

Published: May 22, 2024

Abstract This study aimed to assess the effects of dietary Cyanus depressus (CD) extract on rainbow trout ( Oncorhynchus mykiss ) physiology and health. Fish with an average weight 3.29 ± 0.34 g were allocated four feeding groups, receiving diets containing CD at doses 0 (Control), 0.5 (CD05), 1 (CD1), 2 (CD2) kg −1 for a period 60 days. Results revealed significant improvements in final body weight, gain, specific growth rate groups supplemented g/kg extract. Lipase activity increased notably fish fed CD0.5, CD1, CD2 diets. The CD1 group exhibited highest trypsin activity, while displayed amylase activity. Analysis gene expression levels superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) showed marked increases across all compared control, most enhancement observed Significant variations immunity-related genes among treatments, tumor necrosis factor-alpha (TNF-α) interleukin-1 beta (IL-1β) found diet enriched immune-related was more prominent than control group. Notably, extract, heat shock protein 70 (HSP70) group, decreased CD05 remained statistically unchanged control. Additionally, supplementation altered composition abundance intestinal microbiota trout. In conclusion, our suggests that has potential enhancing various physiological health aspects trout, particularly when g/kg.

Ameliorating effects of natural herbal supplements against water-borne induced toxicity of heavy metals on Nile tilapia, (Oreochromis niloticus)

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Sept. 29, 2024

Abstract The efficacy of herbal supplements in mitigating heavy metals (HMs) toxicity was investigated using a widely grown fish, the Nile tilapia ( Oreochromis niloticus ). experiment conducted over two phases: during stress phase, experimental fishes were exposed to sub-lethal concentrations HMs, including lead, cadmium, zinc, and copper for 15 days; following which feeding given 70 days ameliorate their effects. Seven groups established: control negative group (CON−ve), positive (CON+ve, without any treatment), five with supplementation 1% turmeric (TUR), cinnamon (CIN), ginger (GIN), garlic (GAR), mixture (MIX), respectively. A total 315 distributed evenly tanks (15 per tank, triplicates). results revealed that exposure HMs led significant p < 0.05) alterations all tested parameters, i.e., liver damage growth reduction. supplements, especially MIX groups, ameliorated harmful effects restored fish growth, digestibility, carcass composition, health. In conclusion, study demonstrated effective reducing HMs-linked tilapia. Future studies pertaining mechanisms facilitated by various bioactive substances-linked tolerance are warranted.

Alteration of the Intestinal Bacterial Community in Rainbow Trout (Oncorhynchus mykiss): The Role of Animal, Plant, and Microbial Diets

Microbiology Research, Journal Year: 2024, Volume and Issue: 15(4), P. 2199 - 2209

Published: Oct. 26, 2024

Intestinal bacterial community in rainbow trout (Oncorhynchus mykiss) is increasingly recognized as important for aquaculture and fish health. This review summarizes the current knowledge on how various feed components, including animal- plant-derived ingredients, well other additives, influence gut microbiota of trout. Studies using 16S rRNA gene profiling metagenomics demonstrate dietary changes affect composition, diversity, functionality communities. The findings suggest that there no single optimal alternative ingredient feeds, but emphasize ratio natural components plays a more significant role shaping intestinal balance crucial maintaining functionality, overall health, thereby promoting growth disease resistance, while enhancing efficiency. use popular animal protein derived from larva Hermetia illucens increases amount Pseudomonadota, chitin they contain can prevent absorption nutrients. Thus, development formulas requires careful selection balancing ingredients to sustain healthy well-being.

Abstract The implementation of omics technologies and associated bioinformatics approaches hold significant promise for generating additional evidence food feed risk assessments thereby enhancing the European Food Safety Authority (EFSA) capacity to deliver scientific opinions guidance documents in future. To explore this possibility, EFSA launched a Call development roadmap identify main actions needed wider use Omics future assessments. address objective, action outlines six project proposals. These proposals are based on comprehensive mapping state‐of‐the‐art research, EFSA's activities as well current planned from other relevant regulatory bodies organisations. outlined recommendations also some identified knowledge gaps highlight added value that further investments different & safety domains could bring. In addition, work addresses key challenges blockers might hinder integration assessment leverages opportunities cooperation with external stakeholders. Finally, provides suggestions how may more broadly effectively engage stakeholders science.
