Book (series)Social and economic performance of tilapia farming in Brazil 2019
Also available in:
No results found.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. -
Book (stand-alone)Social and economic performance of tilapia farming in Africa 2017
Also available in:
No results found.World tilapia aquaculture production grew 12 percent annually, from less than a half million tonnes in the early 1990s to over 5 million tonnes in the mid-2010s. Africa accounted for 20 percent of the growth. Yet most of the contribution came from Egypt, whereas in the mid-2010s countries in sub-Saharan Africa accounted for less than 20 percent of tilapia aquaculture production in Africa and less than 4 percent of the world production. In light of the potential fish demand driven by population a nd economic growth in Africa where tilapia is a native species favoured by most consumers, there is little doubt that there is great potential for the development of tilapia farming in Africa and in sub-Saharan Africa in particular. However, an appropriate development policy and sector management are needed to realize the potential. This collective volume includes five studies on tilapia farming in Egypt, Ghana, Kenya, Nigeria and Uganda, which together accounted for nearly 95 percent of Africa’ s tilapia aquaculture production in the mid-2010s. Each study provides a comprehensive account for the development of tilapia farming in the respective country with focus on the social and economic dimensions. Tilapia value chains are analysed in the context of the entire aquaculture or fish value chains from various perspectives (e.g. technical, economic, social and institutional). Issues, constraints and challenges are highlighted and discussed. Potential solutions are recommended. Despite the vast information and knowledge provided by the studies, there are still many unknowns about tilapia farming in Africa, especially on the economic performance. Further study is needed to fill the information and knowledge gaps. -
Book (series)Tilapias as alien aquatics in Asia and the Pacific: a review 2004
Also available in:
No results found.Tilapias are not native to Asia but have been a significant component of inland fisheries and aquaculture in the region for over half a century. They have been introduced into over 90 countries worldwide, with a global distribution second only to common carp. The contribution of tilapias to global aquaculture production has increased over the past three decades with production in 2002 exceeding 1.5 million tonnes with an estimated value of US$1.8 billion. The average annual growth rate in aquacu lture and capture fisheries production of tilapias from 1970 to 2002 has been 13.2 percent and 3.5 percent, respectively. In the present context of development, success of a species is determined not only by its contribution to production per se, but also by its social, cultural, economic and environmental impacts. Although tilapia has been associated with adverse environmental impacts, detailed analysis of the literature suggested that other factors, such as overfishing, environmental degradati on from land-based activities, and changes in hydrological regime have probably been more responsible for adverse impacts. It is clear that numerous factors working together can impact biodiversity. It is also clear that tilapias, as a group of alien species, have made a significant contribution to food production, poverty alleviation and livelihoods support in Asia and the Pacific. In spite of the wide-scale introduction into Asian waters, there is scant explicit evidence to indicate that tila pias have been overly destructive environmentally.
