KONDISI KUALITAS AIR, PERTUMBUHAN DAN SINTASAN LOBSTER AIR TAWAR (Cherax quadricarinatus) PADA PENGGUNAAN PENEDUH DAN PAKAN YANG BERBEDA
ABSTRACT: Most crayfish
(Cherax quadricarinatus ) cultures in Indonesia still use indoor system with
constant temperature, which is different from outdoor system having high
temperature fluctuation. C. quadricarinatus is omnivorous and opportunistic
polytrophic requiring high protein (22─53 %) feed. A study on the water
quality, growth and survival rate of C. quaddricarinatus treated with different
covering and feed nutrient content was conducted in 12 weeks employing
Completely Random Design (CRD) arranged in a factorial treatment design (5x2).
Statistical analysis showed that cover treatment had significant influence on
the growth (P<0.05). Feed treatment had no influence on the growth
(P>0.05). The best growth and survival rate show in water-hyacinth covering
of 50 %.
