induced masculinization in some ﬁsh species can provide a foundation for clarifying the molecular mechanisms of TSD or GSD TE. 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:

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.
