Seedling

A. Maintenance Association
- Master-parent dikolam maintained with the density 0.5 kg/m2. Each day be given additional feed Pellet form as much as 3% of body weight of fish and given s 3 / 4 times per day. By the rainy season, plus the amount of feed to 4%. Master female weighing 4 kg of eggs can produce as much as ± 400,000 eggs.

o spawning new dirstyboys can be performed Induced spawning, for the female hormone disuntikan with LHRH-a 3 ug / kg or ovaprin 0.75 ml / kg. For male uses LHRH-a 2 ug / kg or ovaprin 0.5 ml / kg. LHRH-a reconstitution in 0.7% NaCl solution.
o Master in the female injection twice with the lapse of time 8 - 12 hours. The first injection of as much as 1 / 3 part of the total dose and the second injection of 2 / 3 him.
o Master states that have been entered into happa spawning, which was installed in the vessel spawning. During the spawning water flow must be fixed. Spawning usually occurs 3 s / d for 6 hours after injection of the second.

C. Hatching
After the eggs are taken to use the net scope fine, and then incubate the eggs in the aquarium, which has been equipped with Aeration and water heater with a temperature of 27s / d 29 0C. Egg density between 100 d 150 eggs / liter, usually the eggs will hatch within 16 hours up to 24 hours.

D. Maintenance flyblow
Flyblow kept in the same aquarium, but ¾ of the water before disposal. The density of the separation flyblow 50's 100 birds / liter flyblow the age of 4 days in the form of news feed naupli Artemia, Brachionus or Moina. Maintenance flyblow lasted for 21 days.

• Maintenance in the pool during the 21 days.

DISEASES
The disease is caused by parasites, bacteria and Moth (mushroom).

- Parasites
"Ich" or "White spot", attack the fish when the water temperature is low (cold), namely how to cope with the international temperature (with the water heater) to less than 29 degrees Celsius and 25 ppm of formalin.

- Moth (mushroom)
Mold is a result of the wounds caused by handling of the less careful. How to cope with Permanganate (PK) s with a dose of 2 / 3 ppm.


- Bacteria
Streptococcus sp. And Kurthia sp. How to overcome that is by using anti-biotic doses of tetracycline with 10 mppm.
