**Fort Wayne, IN** – A new study published in PLOS ONE reveals that supplementing Nile tilapia with Vitamin C and Zinc can significantly enhance their immune response and growth rate even when exposed to cold water stress. This research provides a potential solution to the challenges faced by tilapia farmers in colder climates.

Tilapia, a popular food fish, thrives in tropical waters but struggles to grow at lower temperatures, limiting its production in regions with colder climates. This study investigated the effects of Vitamin C and Zinc supplementation on tilapia’s resilience to cold stress, using an experimental setup where fish were subjected to optimal (26°C) and cold (15°C) water conditions.

The results demonstrated that:

* **Vitamin C and Zinc supplementation significantly improved immune response and wound healing in cold-stressed tilapia.** Fish receiving these supplements showed a faster recovery from tissue damage and a reduced inflammatory response compared to control groups.
* **Supplementation with Vitamin C and Zinc maintained growth rates comparable to control fish in warm water conditions.** This suggests that these supplements can help offset the negative effects of cold temperatures on tilapia growth.

These findings highlight the potential of using Vitamin C and Zinc as essential dietary components for tilapia farmers, particularly in regions with suboptimal water temperatures. The study suggests that supplementing feed with these nutrients could improve fish health, boost productivity, and increase profitability in cooler climates.

This research provides valuable insights for the future of tilapia farming, potentially allowing for greater expansion of production into new regions and reducing the need for expensive indoor facilities.
