How to raise pike crabs, can pike crabs be farmed

The pike crab itself grows in the ocean, and when breeding, it is necessary to ensure that the water quality in the pond is salin, clean and pollution-free.

The water level should not exceed 3 meters, and then small fish and shrimp are placed in the pond to provide bait for the pike crabs.

The first of the pike crab crab seedlings mainly has two kinds of fishing natural sea area and artificial cultivation, and the specifications of the seedlings are generally selected 80 kq is better.

Crab seedlings are required to be neat in size, robust in physique, complete in appendages, strong in vitality, and less than 10% in soft shell rate, and stocked from late May to mid-June.

When breeding pike crabs, you should insist on eating more and a small amount, check and look at it frequently, and pay attention to the freshness and palatability of the bait.

Barracuda crabs can be farmed. As an animal with strong survival ability in the ocean, as long as it can provide a suitable living environment for pike crabs, there is no problem in artificial breeding.

The crab meat is fat and delicious, has high nutritional value and economic value, and is suitable for temporary breeding and fattening of seawater. cephalothorax fusiform, almost twice as wide as long; The cephalothorax surface is covered with fine granules, with 2 granular transverse embankments and 3 verrucous protrusions; forehead with 2 sharp teeth; The anterior lateral margin has 9 acute teeth, and the terminal teeth are long and spiny, protruding outward.

The body color of the pike crab varies depending on the surrounding environment. Specimens living on the sandy bottom have a pale grayish-green cephalothorax, a round white spot in the anterior gill region, a purplish-red chelicerae with white spots for the most part, a part or all of the ventral surface, and the first three pairs of long legs and carpal segments are also white.

The palms are blue-white, soft bristles are brown, the knuckles are purplish-blue or purplish-red, the fourth pair of feet are green with white spots, and the fingertips are purple-blue. Individuals living among seagrass have a darker body color. It is omnivorous, eating fish, shrimp, shellfish, and algae, and even eating the same kind, and likes to eat animal carcasses.

1. Barracuda crabs can be farmed.

2. Choose a suitable pond. It is best to choose a pond in a place where there is no wind and waves, and the tide can flow freely; At the same time, the water in the pond should be clean enough and rich in oxygen. It is best to have a slope made of fine sand in the pond.

Barracuda crabs like to dive into the sand, and the presence of fine sand in the pond can make them more active and vibrant; It is best to have shrimp roe and trash fish in the pond so that they have enough food.

3. Add an aerator. The aerator can continuously fill the water with oxygen to ensure that the dissolved oxygen content of the water reaches the standard value. It is conducive to the growth and breeding of pike crabs, so that they can grow healthily and have better meat quality.

4. Clean up the pond. In order to ensure the healthy growth of the pike crab and the delicious meat, we must ensure that the pond is clean. The pond should be cleaned of silt and disinfected before farming.

5. Choose high-quality pike crab seedlings. There are four types of pike crabs: green shells, yellow shells, flower shells, and purple shells, among which the green shell crab has the best quality.

6. Set up a cultivation pool. The phenomenon of bullying the small with the big in the pike crab occurs from time to time. In order to prevent larger crabs from bullying smaller crabs, we should classify and breed crabs separately according to their growth and size to ensure that each crab can grow healthily.

7. Male and female are raised separately. Due to the practice of polyculture staring method, it is found that the yield is extremely low, and the ** of male pike crabs will be much lower than that of female pike crabs in winter, and it is a good method to choose male and female to be raised separately. Not only does the yield of pike crabs be maximized, but it can also be used to select the best quality crabs in the right season, so as to maximize the benefits and improve the growth of crabs.

8. Choose the right feed. In order to make the crab live in good condition and get delicious crab meat, it is important to supplement them with the necessary nutrients in time. For the selection of feed, it is necessary to observe the growth of crabs in a realistic manner.
