ABSTRACT
Florida red tilapia (Oreochromis urolepia hornorum X O.
mossambicus hybrid) fingerlings were fed on three levels of aquatic
plant proteins (10, 20 and 300/0 of seaweeds, macro algae and azolla)
in complete diets. The results showed that replacing plant proteins
(Soybean meal and Wheat milling by products) with aquatic plant
proteins increased growth performance and feed utilization of Florida
red tilapia at the level of 100/0 Seaweeds or Algae and 20% of Azolla
respectively. Productive protein value and energy utilization by
Florida red tilapia decreased by increasing the level of replacement
with Seaweeds or Algae to more than 10% and level of Azolla more
than 20%. It is therefore, recommended to use 10% of Seaweeds or
Algae and 200/0 ofAzolla to diets containing mixture offish meal and
soybean meal for feeding Florida red tilapia fingerlings.
