KULTUR MASAL CHIDORIDAE
ABSTRACT: The goal of mass
culture of chydoridae is to find out the density of chydoridae that was
cultured with yeast and rice bran.
Chydoridae was cultured on 5 aquaria i.e 3 aquaria measuring 100 x 60 x
cm (A, B and C) and 2 aquaria measuring 30 x 30 x 30 cm (D and E). Water quality parameters measured were
temperature and pH. The result of
chydoridae mass culture for 21 days reached the peak on 14th day with the
result as follow : for aquarium A with the concentration of yeast and rice bran
0.05 g/500 mL is 31 individue/ml; aquarium B with the concentration of yeast
and rice bran 0.03 g/500 mL is 13 individue/ml; aquarium C with the
concentration of yeast and rice bran 0.03 g/500 mL is 5 individue/ml; aquarium
D with the concentration of yeast and rice bran 0.005 g/500 mL and aquarium E
with the concentration of yeast and rice bran 0.003 g/500 mL can not be
detected. Counting the density of
chydoridae on 21st day gave the result as follow : aquarium A as much as 4
individue/ml; aquarium B as much as 3 individue/ml; aquarium C as much as 2
individu/ml; aquarium D as much as 1 individue/ml and aquarium E as much as 2
individu/ml. During culturing, water
quality such as temperature and pH were on the range that was not harmful the
chydoridae life.
