The Nile tilapia are the third most important aquaculture fish after carp and salmon, and males grow significantly faster than females. The whole genome of the Nile tilapia was sequenced

The Interactive Effect of Temperature and Salinity in the

As a tropical freshwater species, Nile Tilapia are subject to both Winter Stress Syndrome and saltwater intrusion as global climate change progresses, making them an ideal model organism. In order to test the physiological limits of this species, we exposed Nile Tilapia to a variety of treatments (two temperatures: 21°C & 14°C, three salinities:

Unfortunately, intensive aqua-farming is accompanied by several problems where infectious diseases come first in limiting the production with consequent negative impact on growth, fecundity and productivity.

Nile Tilapia Broodstock Selection, Seed Quality and Density

The quantity of Nile tilapia culture has risen significantly in the Philippines, by almost 4% annually, with a 33% increase between 1997 and 2002 (BFAR 2006 www.bfar.da.gov.ph). To support the growing tilapia industry, there is a need to provide year-round, high-quality seed that can be widely distributed at reasonable costs to tilapia farmers.
