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. 

Aquaculture in Ghana has overcome its historic fits and starts and is helping to narrow the gap between domestic seafood production and consumption. Production is based on Nile tilapia. 

When producers and markets are separated by long distances, economic losses can occur. In a review involving tilapia, water quality was adequate in hauling trucks, although pH levels dropped during transport. 

A recent study that evaluated the benefits of using probiotics with a balanced mixture of Bacillus bacteria strains to inhibit pathogenic bacteria in tilapia. 

YY male tilapia technology, based on the genetic manipulation of sex, provides a robust, reliable method of achieving male fish. It avoids the use of hormones and maintains strain purity in genetically normal males. 

A series of experiments showed that fishmeal is not an essential ingredient in hybrid tilapia feeds and that plant protein-based diets can yield results similar to those obtained with diets containing 10 percent fishmeal. 

The introduction of tilapia to irrigation reservoirs in Israel improved the efficiency of water usage and reduced the cost of water needed for tilapia culture. Although requiring considerable investment, many dual-use reservoirs were constructed and equipped for efficient harvesting. 

A laboratory study at the University of Arizona examined the effects of tilapia to control EMS and mortality in Pacific white shrimp.in controlling AHPN.
