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. 

As more-intensive methods for tilapia and catfish culture become popular in Namibia, practical diets need to be formulated using local ingredients such as maize, millet, wheat bran and fishmeal to reduce feed costs. 

A survey of major market sectors to identify further market potential for fresh tilapia found that both big-box retailers and traditional grocery stores offered little room for achieving premium prices for tilapia fillet products. 

Herbivorous or omnivorous fish like tilapia can be fed lower-energy and lower-protein diets because they consume higher amounts of feed than carnivores. 

Sustainable development of China's tilapia industry depends largely on the market prices of products, disease control, climate and seed availability. 

Salinity tolerance in tilapia can be improved by optimizing acclimation protocols, adding salt to the diet or hybridization between fast-growing and salt-tolerant species. 

With a hatchery system that involves collection of eggs and larvae, and hormonal sex reversal, it is possible to produce billions of monosex tilapia (all-male) fry to satisfy demand and accelerate aquaculture development. 

The wide distribution and ongoing improvement of GIFT tilapia in Sri Lanka is raising living standards and employment for women in rural areas.
