Best Strategies for Spawning Carp in the Pond
Description: spawning carp (Cyprinus carpio) in the pond requires the right strategies. Here is what you can do.
Common carp is one of the most popular freshwater fish to consume around the world. While they are considered wild fish, spawning carp (Cyprinus carpio) in a pond is an alternative to get a steady supply of this fish. The domesticated species tend to be bigger and fatter than the wild ones, but they require the right condition to keep.
Here are things to do if you plan to keep common carps in a pond.
Water Condition for Common Carps
There are two subspecies of common carps: Cyprinus carpio and Cyprinus yilmaz. The first ones live in the Danube and Volga Rivers, while the second ones live in Turkey. Many domesticated common carps came from the European species, which have been domesticated in ponds since Ancient Rome era. Therefore, to keep this fish in a pond, you need to mimic the natural habitat.
To create the carp's pond, you need to have a water temperature that ranges between 23 and 30 degrees Celsius. One pond can be a habitat for common carps with similar neighbors, such as tilapia, mullet fish, or Chinese carps. Aside from regular pond, you should create separate spawning/breeding pond, nursery pond, and two brooding ponds (to keep mature male and female fish separately until you are ready to spawn them).
How to Spawn Carps in Breeding Pond
First, prepare the breeding and nursery ponds by filling them with water and nutritious organisms such as Daphnia or Moina. Put a net at the bottom of the breeding pond to make the transfer of the eggs easier (called kakaban, based on an Indonesian spawning method from West Java area). Adult fish are usually ready to breed in January-March and July-August. Transfer the male and female fish to the breeding pond, and wait until they produce eggs.
One female carp can produce about 300,000 to 800,000 eggs, which must be treated with dry fertilization method, tannin/urea bath, and Woynarovich method. These steps ensure that the eggs are in their best conditions before being incubated in Zoug jars. The small hatched fry may be kept in separate tanks first before being released to the special nursery pond. The microorganisms will become nutritious foods for these fries before you release them to the regular pond.
Carps are not only tough and have high economic value, but they are also delicious. Carps can be cooked by searing, grilling, or frying them, and you can sell them to local restaurants. Knowing the way of spawning carp (Cyprinus carpio) will give you the opportunity to raise profitable freshwater fish, especially since they are considered pests if being left in the wild.
