aquaculture, as in all food production sectors, one of the external
inputs required for successful fish production is chemical.
Chemicals are indeed an essential ingredient to successful
aquaculture, which has been used in various forms for centuries
(Subasinghe et al., 1996). Aquaculture chemicals can be
classified by the purpose of use, the type of organisms under
culture, the life cycle stage for which they are used, the culture
system and intensity of culture, and by the type of people who
use them. Intensification of aquaculture brings about the use
of more chemicals and antibiotics in this sector. Chemicals
and antibiotics are important components in health
management of aquatic animal, pond construction, soil and
water management, improve natural aquatic productivity
