innovative and plant-based feed formulations
Research Activities
Harnessing agricultural by-products to enhance fish health and reduce reliance on conventional feed ingredients
Research Focus
AgrI-fiSh is a research project dedicated to advancing sustainable aquaculture through the development of innovative and plant-based feed formulations. The project applies circular economy principles by utilizing agricultural by-products to replace conventional feed ingredients, reducing dependency on fish meal and fish oil and boosting the immune system of fish through the use of medicinal herbs and lactic acid bacteria (LAB).
Experimental Research and Trials
The research involves the formulation and testing of feeds designed to enhance fish health, improve product quality, and minimize environmental impact. The pilot project has been developed in Italy, in Visso at the premises of the local firm Aquaculture Cappa, and experimental diets have been tested in controlled aquaculture environments to assess:
The research involves the formulation and testing of feeds designed to enhance fish health, improve product quality, and minimize environmental impact. The pilot project has been developed in Italy, in Visso at the premises of the local firm Aquaculture Cappa, and experimental diets have been tested in controlled aquaculture environments to assess:
Growth Performance
Evaluating weight gain, feed conversion ratio, and overall fish development.
Nutritional Quality
Analysis of fillet composition, bioactive compound retention, and shelf-life improvements.
Immune and Antioxidant Response
Investigating the impact of feed on fish health, stress resistance, and disease prevention.
Environmental Impact
Assessing water quality parameters and reducing nutrient waste discharge.
Gonad Maturation
Exploring the influence of feed formulations on reproductive development and fish welfare.
Two different diet formulations have been tested on trout, respectively on 900 Fario trouts (Salmo trutta fario) and on 400 Rainbow trouts (Oncorhynchus mykiss) and a third formulation, which has been patented, will be tested before the end of the project.
In order to capitalize the system, in Spain a new formulation suitable for Seabass (Dicentrarchus labrax) is in its testing phase and in Algeria similar formulations have been prepared and tested on Tilapia (Oreochromis niloticus).
Scientific Findings and Impact
Preliminary results indicate that the patented diet maintains fish growth while offering functional health benefits. The research suggests that innovative feed formulations can contribute to more resilient and high-quality aquaculture practices, aligning with sustainability goals.
Publications and Further Research
AgrI-fiSh findings have been published in peer-reviewed journals, contributing to scientific advancements in sustainable aquafeeds. Ongoing research aims to further optimize feed formulations and expand the application of circular economy strategies in aquaculture.
