Background
• rainbowfish is originated or endemic indonesia that high value and considerable commercial interest but have danger status
• rainbowfish culture have hatchery problems is long hatching
• temperature have limiting effect of rainbowfish because rainbowfish is poikilotermic animal
• important information of organism's reproductive biology especially embryogenesis and hatching rate of rainbowfish
Problem Notation
• Is it temperature have influence of embryognesis and time incubation rainbowfish eggs?
• How many optimal temperature to maximal hatching rate?
The Aim
The aim of research is knowing influence of temperature to embryognesis, time incubation, and optimal temperature to
maximal hatching rate of rainbowfish eggs
Stead
Provide information about optimal temperature to embriogenesis and
hatching rate for maximal production of rainbowfish eggs

Research Methodologi
• pre research for event of eggs reversal (eggs at substrat) so knowing high current with needed and get optimal type sieve for eggs rainbowfish culture (flat or concave).
• primary research use RAK with eksperiment. this research there are 4 treatment and 4 frequent. Treatment temperature culture at 27°, 28°, 29° dan 30°C, and class of this reseach is days.
Variable of Research
• independet : temperature• dependent : embryogenesis and hatching rate • control : spesiess of fish, nutrient, tools,
water quality (pH and DO).
