Herbal essential oils improve growth, antioxidant response, and gene expression in Nile Tilapia fingerlings.

ABSTRACT:

Introduction

The increasing global demand for sustainable aquaculture practices has prompted the search for natural and effective alternatives to synthetic feed additives. Herbal essential oils (HEOs) have emerged as promising candidates due to their bioactive properties that support growth, health, and immunity in fish.

Methods

This study evaluated the effects of dietary supplementation with blended HEOs-comprising carvacrol, oregano oil, 1,8-cineole, thymol, α-pinene, β-pinene, limonene, and propylene glycol-on growth performance, hematological indices, antioxidant status, immune response, intestinal morphology, and gene expression in Nile tilapia (Oreochromis niloticus) fingerlings. Over a 72-day trial, fish were fed diets with 0 (control), 30, 60, 12
