My Deep-sea Fishery

Xiang Yang secretly said in his heart that this stubborn female shop owner is still delicate in heart, and has not forgotten to remind customers that Pippi shrimp is actually dangerous.

However, Xiang Yang was also an expert in this way. He smiled and paid the money, indicating that he knew it.

Seeing that Xiang Yang didn't take her words to heart, the female boss couldn't help being a little angry.

"Mantis shrimp is a burrowing shrimp. It often burrows on the sandy bottom of shallow seas or silt. It can even dig the rocks on the bottom of the sea." The female boss whispered.

Xiang Yang was taken aback for a moment, then smiled, and said, "Don't worry, I know what you mean, but I don't know much about Pippi Shrimp than you."

Pipi shrimp is an extremely ferocious carnivorous animal among mouth-footed animals.

Although Pipi shrimp mostly preys on small invertebrates, this type of animal can make sounds by rubbing its tail limbs against the ventral surface of the tail section or by striking with its limbs.

But the ferocity of Pippi shrimp is beyond doubt.

Pipi shrimp has very sharp eyesight and is very good at swimming.

Therefore, most of the prey of Pippi shrimp are benthic creatures that are not good at swimming, including various shellfish, crabs, and sea urchins.

Adult Pippi shrimp can easily destroy the outer hard shell of the prey and enjoy the meat inside.

In addition, there are some Pippi shrimps that are very good at ambushing, and a strong attack can put the enemy to death.

Lobsters wearing calcified armor and crabs passing quietly on their toes are also often targeted by Pippi shrimps.

Xiang Yang once saw a kind of Pippi shrimp with two hammer joints. A violent blow can destroy the crab's nervous system and kill the crab on the spot.

Some Pippi Shrimp will use the barbed arm under their head to stab the food quickly, which is quite like a praying mantis.

There is also a Pippi Shrimp with palm joints that is even more powerful.

Pippi shrimps with palm joints are lighter, and their protective devices have evolved to withstand continuous blows, like ancient Roman gladiatorial fights. They hide behind a shield made of curled tails to avoid enemy attacks. .

Pippi shrimp is extremely aggressive and often acts fearlessly. It can catch cephalopods that are ten times larger and ten times heavier than its body.

Even if octopus and other cephalopods find a crack to hide, they dare to approach the Pippi shrimp nest after thinking twice.

It is said that after the main enemy of Phi Phi shrimp is caught in the open air, they always fight. Phi Phi shrimp struggling in the hunter's mouth are difficult to swallow, and many of them are spat out intact.

This smart marine creature has a pair of powerful clips, which are quite powerful when launching an attack, which can break glass and even pinch human fingers.

Biologists said that Pippi shrimp ranked second in the animal attack speed rankings, second only to the big jaws of soldier ants.

Some species of Pippi Shrimp even have a pair of hammers that can strike at a speed of 60 kilometers under the body.

When the Pippi Shrimp attacks its prey, it can eject the hammer within a ten-thousandth of a second. The impact force of the ejection can reach ten meters, and the high temperature generated by friction can even make the surrounding water emit electric sparks.

Pippi shrimp can eat fish, shrimp, and shellfish, but it is better to live small shellfish.

Breeding Pipi shrimp should avoid polluting the water quality. It is better to use small pieces of bait in the wild, and distribute it evenly to facilitate ingestion, increase the amount of bait eaten by half and reduce mutual killing due to preying.

According to the characteristics of nocturnal emergence of mantis shrimp, feed once a day in the evening, and the amount of bait is 5%-20% of the weight of the parent mantis shrimp, and depends on the egg holding status, water temperature and weather conditions of the mantis shrimp. , The types and quality of bait are increased or decreased appropriately.

In the early stage of cultivation, the amount of bait can be appropriately increased to provide adequate nutritional requirements for the gland development of the prawns, and basically do not eat. Therefore, it is estimated that most prawns should reduce the amount of bait when holding eggs.

In addition, after hatching, Pippi shrimp will grow and increase its food intake. It will also interfere with other egg-bearing mantis shrimps. Therefore, it is best to use ground cage nets to trap them out of the pond.

During the cultivation period, patrolling the pond is a necessary work to check the inflow and drainage, the activity and feeding of mantis shrimp, the water quality, especially the discharge of the larvae. Once the broodstock crickets are found to emit pseudo-flea-like larvae, the larvae are collected into the nursery pond for seedlings.

Of course, the two most difficult steps in breeding Pipi shrimp are hatching and training.

The spawning and reproduction of Pipi shrimp has strict requirements on environmental conditions, especially the substrate, caves and light. Without suitable conditions, it will not lay eggs, or even if it lays eggs, it will not hatch. Therefore, put the soft mud collected from the intertidal zone in the bottom of the glass fiber cylinder, flatten it, add sea water to a place 30 cm away from the mud surface, soak it with sodium hypochlorite for 24 hours to disinfect, then neutralize, wash, and make the tank inside The pH value of the seawater is the same as that of the filtered seawater, and then cover it with a black cloth for later use.

Xiang Yang has a good command of how to cook Pipi shrimp. Xiang Yang has seen people choose 16 or so broodstock with mature gonads that are large, lively and fully appended.

After being disinfected by formaldehyde, put it in the incubator.

Pippi shrimp has a strong ability to dig caves. As long as the substrate and environmental conditions are suitable, the sexually mature mantis shrimp can be completed in a short time. Between 1.5 and 3 cm. Mature egg cells are round, with a diameter of about 410-450 microns. They are exhausted at one time, and they are held on the mouth with their jaws and feet and keep rotating. As long as the egg mass is not broken or is not stimulated by the outside world, it will always be held.

From a few hours to a few days, if there are external stimuli such as strong light, rapid water, large water temperature differences, etc., the egg mass will be quickly thrown away. The cleavage form of the fertilized eggs of mantis shrimp is surface cleavage, which is incubated under running water for about 20 days at a water temperature of 26-28°C, and cultivated to the larvae of the mantis shrimp pseudo-daphnia, that is, the larvae of the pipi shrimp. "

During this period, the water flow should be controlled. It is advisable not to mix in the tank, and the outflow and incoming water should be equal, and the water should be replaced with a 100-mesh sieve. The dissolved oxygen content in the tank should be greater than 5 milligrams liters.

Spawning, hatching and larvae are all completed in the cave together with the mother. When the larva leaves the cave and the mother and floats in the water, it is a metamorphic mantis shrimp larva.

It takes 3 to 4 months for mantis shrimp larvae to metamorphose to juvenile mantis shrimp. The larvae should be separated from the original breeding tank at this time.

In addition, the transportation of Pippi shrimp is also a very difficult thing.

After the small Pipi Shrimp is purchased, it should be transported to the nursery plant as soon as possible and placed in the broodstock pond for temporary cultivation.

Small Pipi Shrimp can be transported by moving water boat transportation, nylon bag oxygenated transportation, dry moisturizing transportation, canvas bucket and other methods for transportation with water.

Even so, in order to ensure the quality of Pipi shrimp and increase the egg holding capacity, merchants should pay attention when purchasing Pipi shrimp. Pipi shrimp should be out of water for a short time, the gonadal development is good, the body is strong, the appendages are complete, and there are no scars. , Strong vitality, bright body color.
