Host-pathogen interaction unveiled by immune, oxidative stress, and cytokine expression analysis to experimental Saprolegnia parasitica infection in Nile tilapia.

The present study evaluated the pathogenicity, immunological, and oxidant/antioxidant responses against Saprolegnia parasitica (S. parasitica) infection in Nile tilapia (Oreochromis niloticus). Three groups of Nile tilapia were assigned as the control group (no zoospores exposure).

Nannochloropsis oculata supplementation improves growth, immune response, intestinal integrity, and disease resistance of Nile Tilapia.

Objective: The current study evaluated the potential roles of incorporating Nannochloropsis oculata into the diet of Nile Tilapia Oreochromis niloticus in an 8-week trial.

Methods: Dietary supplementation of N. oculata was tested at inclusion levels (0% [control], 5% [N5], and 10% [N1]) in triplicate.
