Summary
This summary is machine-generated.Natural products Herb-All PARA-X® and Herb-All CALM® effectively treated ectoparasites in Nile tilapia. These treatments reduced parasite load, improved immune responses, and downregulated key inflammatory genes, enhancing overall fish health.
Area Of Science
- Aquatic Animal Health
- Veterinary Parasitology
- Fish Immunology
Background
- Ectoparasitic infestations pose significant threats to Nile tilapia aquaculture.
- Limited effective and safe treatment options exist for parasitic fish diseases.
- Natural products offer a promising alternative for parasite control in aquaculture.
Purpose Of The Study
- To evaluate two novel natural feed supplements, Herb-All PARA-X® and Herb-All CALM®, as in vivo treatments for ectoparasitic infestations in Nile tilapia (Oreochromis niloticus).
- To assess the impact of these treatments on fish health, immune parameters, and gene expression.
- To determine the efficacy of these products in managing Dactyolgyrus sp. infections.
Main Methods
- A total of 400 Nile tilapia were experimentally infested with Dactyolgyrus sp.
- Fish were treated with varying doses of Herb-All PARA-X® and Herb-All CALM®.
- Immune parameters (glucose, nitric oxide, cortisol, lysozyme activity) were measured.
- Gene expression analysis of Tumor necrosis factor-α (TNF-α) and heat shock protein 70 (hsp-70) was performed.
- Histopathological examination of gills and other tissues was conducted.
Main Results
- Dactyolgyrus sp. was the only identified ectoparasite.
- Treated groups exhibited significantly lower levels of measured immune parameters compared to the control group.
- Up-regulation of TNF-α and hsp-70 in infested fish was significantly downregulated by the treatments in a dose-dependent manner.
- Histopathological lesions showed improvement in treated fish.
Conclusions
- Herb-All PARA-X® and Herb-All CALM® are effective in treating ectoparasitic infestations in Nile tilapia.
- These natural products enhance fish health by modulating immune responses and reducing inflammation.
- The study demonstrates the potential of these supplements for sustainable aquaculture parasite management.
