Book Description
The manual describes the net cage of tilapia in dams and small farm reservoirs, which has been found to be a low-cost yet high-income earning farm activity and offers an excellent option as an alternative livelihood for poor inland fisherfolks. The following aspects are covered: 1) Characteristics of a suitable site; 2) Design of the net cages - the floating cage, the stationary/fixed cage; 3) Stocking the net cages - source of juveniles, stocking rate, stocking time, acclimation; 4) Management of the cages - feeds and feeding, monitoring activities; 5) Harvesting - partial harvest, total harvest; and, 6) Profitability analysis.

Book Description
Financial and bioeconomic risks were evaluated for four large commercial Nile tilapia (Oreochromis niloticus) cage projects with production water volume (m 3 ) of 10 to 50 thousand m 3 (Small Volume, SV), 51 to 150 thousand m 3 (Medium Volume, MV), 151 to 300 thousand m 3 (Large Volume, LV) and > 301 thousand m 3 (Extra-Large Volume, ELV). Productivity and economic data were obtained from 232 net cages installed on a commercial farm located in the neotropical reservoir, Brazil, from 2017 to 2019. Cost and profitability analyses, bioeconomic feasibility, and risk and sensitivity analyses were performed using a Monte Carlo simulation. The implementation of commercial tilapia cage farming relies mainly on the feed price. The initial investment demand is proportional to the size of the projects. However, despite the higher investments for the medium, large and extra-large tilapia farms, these projects showed the lowest financial risks. The MV, LV, and ELV projects presented a medium-low risk at 38.67% probability, whereas the SV farm presented a medium to medium-high risk at 51.17% probability. Thus, fish farms with a production volume above 51 thousand m 3 tend to be more profitable and have 35.7% probability of low financial and bioeconomic risk with a Payback period of fewer than 10 years, mainly due to the lower feed costs per mass of fish produced. This study assists investors to choose a better path toward a more viable and profitable activity.

Book Description
Master's Thesis from the year 2012 in the subject Biology - Zoology, grade: B, Norwegian University of Science and Technology (Animal Science - Norwegian University of Life Sciences), course: Aquaculture - Tilapia, language: English, abstract: This literature review has been written to examine different tilapia farming practises both in semi-intensive and extensive systems. Extensive culture is not mentioned sine it is not considered to be a real commercial production as the control over the system is quite limited and even semi-intensive system is being replaced by intensive system due to technological developments, high demand and increasing market prices of tilapa. In first chapter, environmental and nutritional requirements are also mentioned as they are closely correlated play a key role in a succesful production. The results of some recent studies and experiments suggest that tilapia has some superiority over other culture fish like faster growth, ability to utilize different feeds, wide tolerance for high stocking densities and environmental conditions. In addition to these advantages, tilapia do very well in integrated culture systemsboth with aquatic species; carp and shrimps, also crops like tomato and lettuce as well. As a result this study is conducted to prove the advantages of commercialtilapia production covering economic values.

Book Description
This 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. Tilapia value chains are analysed from various perspectives: technical, economic, social and institutional.
