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. 

Ammonia nitrogen occurs in aquaculture systems as a waste product of protein metabolism by aquatic animals and degradation of organic matter, or in nitrogen fertilizers. Exposure can reduce growth and increase susceptibility to diseases in aquatic species. 

A farm project in Namibia established at a lake formed by an old tin mine incorporates a hatchery facility and grow-out cages to raise tilapia. It utilizes an existing water resource to improve food security and ensures the participation of disadvantaged local communities. 

Natural factors, institutional support and a big appetite for fish have all contributed to the growth of aquaculture in Ghana, where about 80 percent of all farmed fish is tilapia. 

In a commercial field trial, Nile tilapia were distributed in net cages and fed diets containing increasing threonine:lysine ratios. 

In a study, tilapia were fed fish oil- or vegetable oil-based diets for five months, then switched to a fish oil finishing diet for three months. Growth and feeding efficiencies were not significantly compromised. 

Although not universally practiced, the potential benefits of selective breeding in aquaculture outweigh all other options for improving animal performance. The genetic potential of aquaculture animals is plastic and can be improved over a relatively short timeframe. 

Fish supply is a food security priority in Bangladesh. There is potential for the culture of non-native fish species to meet its growing population's needs. 

Overall costs for hand filleting tilapia relate primarily to labor and the throughput of fish to be filleted. Labor is the largest expense. Salaries vary, and cutters’ yield efficiencies increase with practice. 

An analysis of tilapia processing in which the cost of the fish was not included found that automated cutting of fillets was significantly less expensive than hand cutting.
