| dc.description.abstract | Koi fish is fish ornamental waters bargaining, one of the constraints in the effort
coltivation koi fish is the level of survival rates low and the growth of fish
relatively slow. This condition is one of them caused by the axistence of the
temperature change or the temperature is not stable, causing koi fish become stress
later died. This study was aimed to determine how big the influence of the The
influence of the temperature against the growth of koi Fish and knowing the
temperature is good for the growth of fish. The experimental design used is
Completely Randomized Design (CRD) with four treatment and three test. The
treatment fish without temperature, temperature 270C, 290C and 310C. The
artificial fish fed as much as twice a day during the study 09.00 and 18.00. turn of
the water as much as 10 % of the volume a total of water done for 3 days before
observatoin. An early stage before done maintenance is the process of the
adaptability for 30 minutes, so is expected to fish can adapt against the treatment.
Fish maintained for 30 days and every 10 days done measurement at all fish
covering long total, heavy and survival rates of fish. Measures of the quality of the
water is temperature, pH and DO. The seeds of koi fish that maintained at a
temperature 270C growth long absolute necessity of 11,74 cm and growth of
weight range 8,61 - 10,36 gr. The value of survival rate maintenance is 100%.
Parameters supporters quality of water oftained from DO changed 5,22 -5,61 mg/l
and pH changed 7,08 – 7,15. The temperature is maintenance koi fish still in a
state of optimally that at temperature 270C. Growth long koi fish have the
influence of the real contained in the treatment B with the temperature 270C. But
in the treatment A, C and D do not have the influence of the real against the
growth of long and weights koi fish. | en_US |
