    HYBRID LIST

    The cichlidae fish family has 1300 varieties, including many small home aquarium types, and the Tilapia branch of the clan has over a hundred different species and countless naturally occurring hybrids.

    I would like to compile a list of popular hybrids, preferably with average growth rates, temperature tolerances, breeding habits, aggression, coloration (maybe pictures), and any special comments regarding the specific strain.

    I will try to compile a comprehensive list in this thread based on feedback from you guys and whatever research I can find.

    I will try to post genetic information where available.

    Re: Known Hybrids

    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.

    Oreochromis aurea x Oreochromis nilotica hybrid, Rocky Mountain White


    Pennyfish™ / Florida Red Tilapia

    Hybridization:
    female Mozambique Tilapia (O. mossambica sp.) X male Wami Tilapia (O. hornorum sp.)

    Average Growth Rate:
    2.2 pounds in 6 months (so they claim)

    Pennyfish™
    1,000 grams in 180 days yields 440 grams fillet (44% fillet).

    versus

    Nilotica Sex Reversed and GMT Fish Hybrid
    1,000 grams in 400-460 days yields 380 grams fillet (38% fillet).

    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.

    Taiwanese Red Tilapia

    Hybridization:
    Mozambique Tilapia (O. mossambicus sp.) X Nile Tilapia (O. niloticus sp.)

    Average Growth Rate:
    1 pound in 6-7 months, 1.5 pounds in 8-9 months

    Lower Temp 100% Mortaility:
    ? Fahrenheit

    Upper Temp 100% Mortality:
    ? Fahrenheit

    Breeding Habits:


    Temperament:
    unknown

    Coloration:
    orange to red

    Strain Specific Traits:
    high salinity tolerance, easily 30% salinity with negligible mortality

    Re: Known Hybrids

    Information put together by our friends at White Brook Tilapia. Below are some experimentally determined results for crossing Tilapia and their resulting male percentages:

    O. macrochir male crossed to female of:
    O. mossambicus - 100% male (Majumdar, 1983)
    O. spilurus - 97.9% male (Majumdar, 1983)
    O. niloticus - 100% male (Pruginin, 1967)

    O. niloticus male crossed to female of:
    O. aureus - 75-95% males (Pruginin, 1967)
    O. horonorum - 75% males (Pruginin, 1967)

    O. aureus male crossed to female of:
    O. niloticus - 50-100% male (Lee, 1979 and Wohlfarth, 1994)... unpredictable results in several studies
    O. niloticus (Stirling strain) - 100% male (Marengoni, 1998)
    O. niloticus (Uganda strain) - 96-100% male (Proginin, 1975)
    O. mossambicus - 100% male (Beardmore, 2001)

    O. mossambicus male to female of:
    O. aureus - 89% male (Pierce, 1980)

    O. hornorum male to female of:
    O. niloticus - 100% male (Lee, 1979 and Wohlfarth, 1990)

    You can also cross many fish from the Tilapia genus with fish from the Oreochromis genus and get all males/mostly males (White Brook Tilapia, 2010).

    We have them in Blue Springs. From what I have seen, they hybridize with blue tilapia.

    Maybe after a couple of beers I'll be able to tell the difference
    but sounds like a cool idea....

    Re: HYBRID LIST

    Meeting face to face is always a good idea if you have a designated driver....
    Rocky whites are good for cold, not for hot. Same goes for pure aurea or niloticus. Mossies are best for heat, salt or other extremes
