    Tilapia is the most popular aquaculture species item farmed in over 120 countries or territories worldwide. Global tilapia aquaculture production grew 11 percent annually (or 13 percent in terms of farmgate value) over the past three decades, from 0.3 million tonnes (USD 304 million) in 1987 to 5.9 million tonnes (USD 11 billion) in 2017. Aquaculture production in Brazil increased 14 percent annually (or 12 percent in terms of farmgate value), from 13 000 tonnes (USD 56 million) in 1987 to 595 000 tonnes (USD 1.5 billion) in 2017, making it a regional aquaculture powerhouse contributing to 20 percent of Latin America and the Caribbean’s aquaculture production in 2017. In Brazil, tilapia has been the largest aquaculture item, contributing to nearly half of the country’s aquaculture production tonnage in 2017. This document assesses tilapia farming and the value chain in Brazil by examining tilapia farming technology and practices, dissecting the tilapia value chain, evaluating the sector’s social and economic performance, discussing the importance of proper governance to the sector development, and highlighting potentials, issues, constraints and challenges in the development of tilapia farming or aquaculture in general in Brazil.

    Today, tilapia is the second most cultured fish species in the world. After 28 years of selective breeding, WorldFish’s genetically improved farmed tilapia (GIFT) is now producing its twenty third generation and is being used by 17 governments around the world. The GIFT strain has improved by nearly 10 percent in growth performance per generation. The selective breeding method has also been successfully applied to other tilapia species, Indian major carps and Chinese silver carp. GIFT yields were significantly higher than non-GIFT yields and GIFT species were more profitable and cost-effective than non-GIFT species. WorldFish has commenced selecting GIFT for resilience against pathogens, for improved feed conversion efficiency and better growth under low oxygen conditions, using DNA-based approaches and genomic tools.
