Improved feeding in tilapia and seabream using genome editing
Research project 12
Project researchers: Dr. Jakob Biran and Dr. Amir Bitan

The increased demand for fish, alongside the reduction in fish abundance in the seas and lakes, drives the expansion of fish farming. There is a need to rely more on sustainable feed resources to support the rapid growth of aquaculture and reduce the use of fishmeal as a primary ingredient in fish feed. However, alternative and more sustainable feed ingredients may reduce feeding and growth. Several works have demonstrated that blockage of anorexigenic factors in fish can result in increased feeding behavior. This study strives to perform genome editing to improve feeding behavior in two major aquaculture species – Nile tilapia and Gilthead seabream.

Fish feed ingredients

A successful outcome of this research may allow the increased use of sustainable feed components for fish aquaculture and reduce the costs and growth times of farmed fish.
