ABSTRACT
MARSANDRE JATILAKSONO. The use of purewater medium on survival rate of Black Ghost fish Apteronotus albifrons in a
closed transportation system with high density. Supervised by Eddy Supriyono and Kukuh Nirmala
The problem has
occurred frequently in export of ornamental fish transportation is a low
survival rate caused by water quality which worsen during transportation. The
one solution of them is using purewater
to medium of fish transportation. This study aimed to determine the effective
comparison of composition of purewater and well water to create the best survival rate of Black Ghost fish
in a closed transportation system with high density. The study was conducted in
laboratory with a simulation of fish transport test. Fish were transported in
difference medium, i.e., treatment A (100% purewater),
treatment B (25% purewater + 75% well water), treatment
C (50% purewater
+ 50% well water), treatment D (75% purewater
+ 25% well water) and Control (100%
well water). The package
system was transport up to 120 hour. The result showed that purewater given effects on survival rate
and water quality of transportation medium. The real effect on survival rate
was began at the 48th hour. At that time, treatment A and treatment D has created highest survival rate (94,17±1,44%),
however in economic analyzed showed that the treatment C mostly profitable. At
the 120th hour, treatment A was created highest survival
rate (69,17+3,82%) too. At that time the Dissolved of Oxygen (DO) was 5,50+0,12 mg/ℓ
and Total of Amonia-Nitrogen (TAN) was 6,77±0,58 mg/ℓ.
Treatment A which content of 100% purewater
have relatively better in water quality and stable in a closed fish
transportation. It was created high survival rate.
