Description
This paper describes a 12-week comparative study of the effects
of aeration vs. non-aeration on growth and survival rates of the freshwater
shrimp, Macrobrachium rosenbergii, reared in outdoor concrete
culture tanks. At four week intervals, the shrimps were counted,
measured and weighed. Shrimps cultivated under aerated conditions
did not grow significantly faster than shrimps cultivated under
non-aerated conditions. Survival rates of shrimps cultivated under
non-aerated conditions were significantly higher than those of shrimps
cultivated under aerated conditions. The physico-chemical parameters
of dissolved oxygen, temperature, pH, turbidity and ammonia concentration
were monitored throughout the experiment. Water hardness was
monitored during the final four weeks only. Water quality was similar
among all tanks, except for pH and dissolved oxygen concentration. From
this study, aeration is not recommended under normal culture conditions
for M. rosenbergii.
