Selection of Masters of Goldfish Chef
The characteristics of a good goldfish broodstock for spawning are having a body length of at least 7 cm or the size of a duck egg that is more than 7 months old.
When viewed physically, good sires have an ideal body shape, wide tail, have erect fins when moving, small head and scales do not fall out.
If you want to produce larvae with a variety of colors, then you should look for brooders that are plain colored but differ between males and females.
To carry out this spawning process, make sure the selected broodstock has a healthy, agile and mature body.
Male Parent Characteristics
To do spawning, of course you have to be able to distinguish between male and female breeders. To distinguish them, you can identify the following characteristics:
- If the abdomen is massaged, a milky white liquid will come out and it is the sperm fluid in the male sires.
- Male sires have small white bumps on the gill cover or sometimes also on the pectoral fins.
- Has an oval-shaped anus and is small
Characteristics of Female Parent
For female sires, the characteristics are as follows:
- If the abdomen is massaged, an egg-shaped yellow liquid will come out
- Have a bigger belly
- Have a round and large anus
How to Spawn Goldfish Chefs
At the spawning stage, you prepare an aquarium or pond and fill it with clean water. Then leave it overnight and place the water hyacinth plant in the pond which can later be used to lay goldfish eggs.
Next, enter the broodstock that has been prepared into the aquarium or pond. Usually this spawning process occurs in the afternoon, and the next morning the eggs are attached to the water hyacinth plant. Then the broodstock can be moved to a holding pond so that spawning can be carried out the following month. After that, allow the eggs to hatch and keep the room temperature so that it is not too extreme and also keep it away from predatory pests.
Egg Hatching Process
The process of hatching these eggs can last for more than 2 days, but if there are still eggs that have not hatched, they will rot and grow with fungus. Make sure at the time of fertilization, the temperature of the aquarium should be maintained between 24 to 28°C. It would be nice if the larvae were given oxygen supply, so that the oxygen intake needed could be fulfilled. In addition, this process must be exposed to sunlight or alternatively can use a light bulb.
Carp Fish Seed Maintenance
After 2-3 days, the eggs will begin to hatch and on day 3, the seeds can be fed. The type of feed in goldfish cultivation that can be given is in the form of water fleas that have been previously filtered.
Then after the seeds are 15 days old, the goldfish seeds can be given additional hair worms.
We recommend that the water level is always kept around 10-15 cm, and make sure the water is replaced once a week with sediment water. So that the temperature is not too hot, you should place the water hyacinth leaves on the surface of the water so that the temperature is not too hot.
Goldfish Chef Enlargement
The next stage of goldfish cultivation is enlargement. This enlargement step should be done after the seeds are 1 month old. At this stage the fry will need more sunlight or warmer temperatures, so you can reduce the water hyacinth leaves.
The food given still uses hair worms, feeding can be done in the morning and if in the afternoon there are still worms left, it should be discarded immediately.
After the fish seeds are more than 4 months old, the fish can be said to be prospective brooders. Prospective male and female breeders should be separated, so that spawning can be done after 8 months of age.
Feeding
The feeding process can be carried out with doses between 3-5 percent of the weight of the fish kept, so large and small fish should be placed in separate aquariums.
Avoid overfeeding, as this can have an adverse effect on water quality and fish health.
Feeding time can be done gradually little by little, so that there will be no feed left that can pollute the water.
That’s a guide and an easy way to cultivate goldfish in an aquarium or in a pond for beginners, hopefully the information above can be useful for those of you who want to try raising these ornamental fish. Good luck!
