La acuacultura ha experimentado su mayor crecimiento en la última década (con un promedio de 8 por ciento por año) en comparación con otras industrias animales, pero todavía está muy por detrás de la producción alcanzada por las industrias avícola, bovina y porcina. 

Brazil will have to deal with an adverse economic and political environment in the next few years. One should expect high value fish products like shrimp, tilapia, Chilean salmon and cod being replaced by more affordable seafood and alternative meats, as consumers keep losing purchasing power due to inflation, unemployment and monetary devaluation. 

The Brazilian aquaculture industry has been growing steadily during the last two decades. Despite facing a number of challenges it is looking at continued growth and a larger role in the export markets. 

Colombian aquaculture production and exports have grown significantly during the last two years, due to a large degree to the efforts of the industry and the producers’ guild, but FEDEACUA has had an instrumental role supporting producers to achieve various industry international certification standards. 

In an opinion piece for the Advocate, the director of ocean sustainability science at the New England Aquarium talks about the F3 Challenge and what the first X Prize for aquaculture could do for the industry: drive innovation.  

Recent surveys indicate that global finfish production has doubled over the last decade, but most of this growth happened in the first half of this period. Production is still growing but at slower pace than in recent years, and annual growth rates must increase to at least 7.2 percent to maintain the double-in-a-decade objective. 

Much of the chemical breakdown of foodstuffs begins in the stomachs of animals through acidification. Effective use of digestive biology is a goal in aquaculture, so dietary acidifiers have been gaining interest in recent years. 

The authors conducted a study to evaluate whether treatment of Trichodina-parasitized tilapia with formalin would improve fish survival and reduce F. columnare infection. Tilapia not treated with formalin showed significantly higher mortality than treated fish. 

A large-scale aquaculture project in Ivory Coast, with "soft technology" adopted by Societe d’Elevage et de Distribution de Poissons, allows the full growing cycle to be controlled using local materials, manpower and inputs. 

The aquaculture industry in Brazil is moving toward further expansion with the support of the federal government. A key strategy of the More Fishing and Aquaculture plan is the development of aquaculture in federal waters. The plan promotes sustainable development of fisheries and aquaculture by linking those involved and consolidating state policies addressing social inclusion, security and food sovereignty. Tilapia is the main farmed fish, although tambaqui and others have potential for large-scale production due to their wide acceptance by consumers. 

The bacterium Flavobacterium columnare and parasite Ichthyophthirius multifiliis (Ich) are common pathogens that can cause heavy economic losses for fish culture. The authors conducted a study to evaluate the susceptibility of hybrid tilapia to F. columnare, including fish mortality and bacterial numbers in fish after parasitism by Ich. 

With interest in culturing tilapia in marine habitats increasing, producers must obtain tilapia capable of growing well in seawater. A study found that both pure-bred and hybrid tilapia performed better in freshwater than in water with high salinity. 

Research that has shown fish have the necessary brain structure to feel pain has displaced traditional perspectives and led to additional accounting for fish welfare in aquaculture. 

Vietnam Organic applied an enzymatic hydrolysis process on shrimp head waste to produce a shrimp soluble extract (SSE) feed attractant that contains a mixture of free amino acids and peptide. 

Within the European market of frozen fish, tilapia play a minor role, with average yearly import quantities below 20,000 mt. China provides more than 80 percent of the total, while Indonesia is the second-largest exporter.
