Large scale commercial culture of Tilapia is limited almost exclusively to the culture of three species: O. niloticus, O. massambica, and O. aureus. Of the three species with recognized aquaculture potential, the Nile Tilapia, O. niloticus, is by far the most commonly used species in fish farming.
Although there are numerous strains of Nile Tilapia, NW Tilapia has concentrated its selective breeding programs with the following three strains.

The Red Nile is widely considered a "true" strain, although it is believed to have initiated from a hybrid of O. niloticus and O. massambicus. The Red Nile has been prized by commercial culture for its rapid growth and weight-to-fillet ratio. Other benefits include tolerance to low water temperature and tolerance to salt water.
The all male production of Red Nile Tilapia is, by far, the most popular choice of our customers.

This is the original Nile Tilapia strain, Oreochromis niloticus, which is a dark colored fish. Having a great fillet yield, we utilize this breed as a base breed for our crossbreeding and hybridization programs.

This strain of Tilapia is considered a "true" strain, however, it is believed to be the result of originally crossbreeding an O. niliticus and O. aurea, then selective bred for the white color. White Nile Tilapia are know to be slightly more cold water tolerant than most other breeds.

We have taken adult Tilapia from our selective breeding programs of O. niloticus (pureline) and O. niloticus (red variant), and have placed them in their own breeding program. Although this program is in its infancy, it has resulted in positive improvements towards fillet yield. It is our goal to continue this selective breeding program, and improve this hybrid.
