this report discusses regarding How to Farm Carp the Conventional Way
remember to go through and listen gradually hence that on your own have an understanding of and can be utilised to your everyday lifetime.
Pet carp has a characteristic physical shape, that is, the body shape is flat, rather long and wide. The entire body is covered with strong scales with slightly rough edges. In the small mouth, tilted or not just below the lips. The lower lip looks a bit poked out compared to the upper lip.
Visually, the appearance of adult carp is different from that of young carp. The basis of the difference can be seen in the size of the body, color, shape of the head and forehead. In terms of behavior and color, young carp are more attractive than adult carp (Sitanggang and Sarwono, 2002). (Also read: how to take care of the father in a tent)
The waters that gourami prefer are calm and deep waters, such as swamps, ponds, reservoirs or lakes. The gourami is equipped with an additional breathing apparatus (labyrinth) so that it can survive in poor water conditions. (Also read: How fast do carp lay eggs)
Pet carp is well suited to be kept at an altitude of up to 800 meters above sea level and grows very well in a temperature range of 24-28ºC. If the gouramy grows below a temperature of 15 C, it will result in slow growth and a disruption of the reproductive system. (Also read: carp farming for beginners)
The way to grow pet carp is to go through several stages. In general, the cultivation of pet carp starts from the nursery, nursery and rearing stages. Nursery is the activity of multiplying plants or animals grown from seeds to produce quality vegetable or livestock seeds. (Also read: how to get big tents fast)
However, this time around, we will provide as detailed information as possible on how to breed pet carp to grow fast, from selecting breeders to harvesting good fish. The next is How to Farm Carp the Conventional Way what you need to know: (Also read: how to live carp in a concrete pond)
1. Selection of parents:
The initial stage that needs to be done in pet carp farming is to choose a broodstock that is ready to spawn. Breeders of pet carp that are ready to spawn are those 3 to 7 years old. To distinguish male and female parents, they can be distinguished based on the following characteristics:
The characteristics of the female parent of the pet carp:
- Forehead has no bump/horn.
- Lighter body color.
- The base of the pectoral fins is dark or black.
- rounded belly
- Relatively long body.
The characteristics of the male parent of the pet carp:
- On the forehead there is a lump/horn.
- Body color is darker and slightly paler.
- The movement is more agile.
- Stomach near the anus.
The characteristics of mother carp that are mature and ready to spawn:
- The belly expands backwards.
- The anus looks reddish white.
- The stomach feels softer when touched.
2. Preparation of the spawning pond
- Drying and cleaning of the bottom of the pool (types of conventional and canvas pools)
- Pool water filling
- Installation of nests (sosog) and supply of materials for the construction of nests.
3. The spawning process of pet carp.
Here’s how to mate with gouramy or what is commonly called the spawning process:
- Introduce mother carp that have passed selection into the spawning pond.
- The number of male and female gourami fish is 1:3.
- Naturally, the male parent will make a nest out of the material that has been prepared. Nest building lasts 15 days.
- Once the nest is ready, the male parent will invite the female parent to spawn in the nest that has been made.
- After spawning is complete, the female covers the nest hole with fibers or dry grass.
- The parent is in charge of protecting her young by moving her flippers towards the nest. In order to increase the level of dissolved oxygen in the water and help hatch pet carp eggs.
- The male father returns to make a nest to continue ignoring other females.
4. Pet carp egg handling
The next step in pet carp farming is handling the eggs. The way to tell that fish eggs are ready to hatch is by the characteristic fishy smell and the presence of oil just above the spawning nest.
Steps for handling pet carp eggs:
- Take the nest containing the eggs and store it in a bucket filled with water.
- Clean any remaining eggs with a net spade or commonly called a spade.
- Separate the eggs from the nest and then place them in a different bucket.
- Wash the eggs well.
- At the time of washing, add Organic Liquid Supplements specialist Pond Ponds & Cages to prevent pests and diseases.
- Place the washed eggs in the hatching tub that has been equipped with a series and a beater.
5. Maintenance and Hatching
The eggs hatch 2-3 days after spawning. Try to hatch eggs in clean water and stable water temperature between 27-28or C. Leave the pet carp fingerlings in the hatchery until they are 10 days old. After the seeds are 11 days old, transfer them to the first nursery tub.
6. Pet Carp Calculation Based on Conversion Coefficient.
According to the calculation results, if the fish are kept at a weight of 200-250 g/head and stocked at a seed density of 1-2 kg/mtwo. After entering harvest age at 500-700 grams/head, the pond condition will not experience excessive density.
The breeding efficiency of domesticated carp can be analyzed based on the weight conversion coefficient. This means that the weight conversion coefficient can calculate the relationship between 1 kg of fish meat and the food needs of pet carp.
For example: to increase the weight of 1 kg of fish meat, 2 kg of pet carp feed is needed, so the pet carp feed weight conversion coefficient is 1 to 2 (1/2). When multiplied by 100%, the weight conversion efficiency value is obtained.
Even so, it must be considered that there must be a balance between energy and protein in the growth rate. If the energy needs of the fish are lower, the protein will be broken down as an energy source. The use of some protein as an energy source causes a delay in the growth of the fish, because the protein plays a role in the formation of new cells.
The amount of energy required for fish growth and maintenance is strongly influenced by many factors, such as the type of species, age, composition of the ration, reproductive rate and standard metabolic rate of the fish.
7. How to know the total weight or weight of fish biomass.
Before you grow pet carp, you need to know the total weight or biomass weight of fish. Sampling was carried out every 4 weeks to obtain the results of the calibration of the actual body weight of the fish.
Taking a random sample of fish and then weighing it, then do the calculation. Example: a 30 m swimming pooltwo stuffed with 300 gourami with an average weight of 100 g/head. Then the total weight or biomass weight is obtained: 300 heads x 100 g = 30,000 g (30 kg).
If the daily feed requirement for pet carp is ±3% of body weight, then the daily feed requirement for pet carp = 3% x 30 kg = 0.9 kg. If the cultivation duration is 1 month, the feed required for the pet carp is 30 days x 0.9 kg = 27 kg.
