Hybrid Blue/Nile & Rocky Mountain White
Hybridization:
Blue Tilapia (O. aureus sp.) X Nile Tilapia (O. niloticus sp.)
Average Growth Rate:
Lower Temp 100% Mortality:
45 Fahrenheit
Upper Temp 100% Mortality:
upwards of 100 Fahrenheit
Breeding Habits:
Prolific breeders
Temperament:
known to be as aggressive as the Nile
Coloration:
usually rather dark; also, light-colored hybrid breed known as "Rocky Mountain White"
Strain Specific Traits:
Considered the fastest growing hybrid. They grow as fast as Nile, but have the cold tolerance of a Blue. They are considered as effective filter feeders as the Blue strain; therefore, fast green-water pond culture becomes feasible.

These growth tests show the final period of time estimated for 95% of a group of Tilapia to reach the goal, results located on the Aquatic Network, LLC website.
Lower Temp 100% Mortaility:
60 Fahrenheit
Upper Temp 100% Mortality:
95-110 Fahrenheit
Breeding Habits:
Prolific breeders
Temperament:
unknown
Coloration:
Orange, fingerlings look like mean goldfish
Strain Specific Traits:
Pennyfish™ hybrid grows from 10 grams to 600 grams in approximately 150 days and grows so evenly that almost all of them can be harvested within a 2 to 3 week period. Also, this method produces 100% males with pure strain breeders.
