CATDOLL : CATDOLL: Can mantis shrimp be cultivated artificially?

1. Can mantis shrimp be cultivated artificially?

Mantis shrimp can be cultivated artificially.

Wild shrimps such as Mantis shrimp have very high requirements for the environment, and they usually live in deep sea areas hundreds of meters below, so the yield is low. Artificially cultivated Mantis shrimps will be larger, but the reproduction efficiency is not high, so the yield has not been improved, but they can still be artificially cultivated.

Mantis shrimp has very high requirements for water quality. It is different from ordinary fish whose requirement for water quality is only average. The waters where it lives must have a very high dissolved oxygen content, greater than 5 ml of dissolved oxygen per square meter, and more than one-third of the water must be replaced every day to keep the transparency at around 50.

Temperature requirements are also a very important part of mantis shrimp breeding. It is a wide-temperature animal. Mantis shrimp can only survive if the water temperature is stable between 6-30 degrees Celsius. But if you want to grow bigger, you must keep it between 20-27 degrees Celsius. Once the temperature changes drastically, all the mantis shrimp will die.

Selection of Mantis shrimp fry

1. When choosing shrimp seedlings, you can choose artificial seedlings or natural seedlings, but most people will choose natural seedlings.

2. When choosing shrimp fry, be sure to choose shrimp fry with sound appendages and strong body. Such shrimp fry can adapt to the environment better during breeding and have stronger survival ability.

3. Among the shrimp seedlings available on the market, there are usually two types: black-spotted mantis shrimp and blue-spotted mantis shrimp, which are the varieties that many farmers often choose. Both of them are relatively large in size, which can not only be better bred, but also generate higher economic benefits.

4. After selecting the shrimp fry, try to reduce the transportation time and shorten the transportation distance to better ensure the survival rate of the shrimp fry.

2. How to keep the mantis shrimp alive for a day?

First of all, oxygen must be added. This is necessary. It is not easy to die if the water temperature is low.

3. How to keep live mantis shrimp (shrimp) alive longer (except using an oxygen tank)

Change the water every day..feed it less..

4. Methods of breeding crayfish

Freshwater lobster, scientific name Procambarus clarkii, also known as red swamp crayfish. Generally, male lobsters are about 1.5 cm long and weigh 50-70 grams; female lobsters are about 10 cm long and weigh about 50 grams. The meat yield of lobsters is about 20%, containing 16%-20% protein, and the protein content of dried shrimps is as high as more than 50%. Lobsters have strong vitality and are not strict on water quality. They are suitable for breeding in lakes, ponds, wetlands, rivers, canals, paddy fields and swamps, and can even survive in some water bodies where fish are difficult to survive. They can withstand high temperatures above 40 degrees Celsius and low temperatures below minus 15 degrees Celsius. They can be bred and naturally overwinter in most parts of my country. At the same time, lobsters have strong reproductive capacity. Female lobsters lay eggs from mid-April to late July every year, with hundreds of thousands of eggs. Fertilized eggs develop quickly and have a high hatching rate. In particular, lobsters grow fast. After the hatched shrimps are hatched, they can grow into adult shrimps after 60-90 days of breeding under the conditions of suitable temperature (20-32℃) and sufficient feed. It has strong disease resistance, few diseases and high survival rate.

1. The area of ​​the artificial breeding pond for lobsters should be 2-3 mu, the water depth should be 0.5-1 meter, the width of the embankment around the pond should be more than 1.5 meters, anti-escape facilities should be built on the embankment, and the water inlet and outlet pipes should be installed in the pond.

2. Selection of broodstock Lobsters are dioecious, and generally require 9-12 months for sexual maturity. Male and female lobsters have distinct characteristics in appearance and are easy to identify. First, for sexually mature lobsters, male individuals are significantly larger than females; second, male lobsters have thick and large feet, and there is a bright red soft tube on the outer side of the two ends of the claw feet. The claw feet of female shrimps are relatively small, and most female shrimps do not have red soft warts on the claw feet, and even if there are, the color is lighter; third, the genital opening of male shrimps is at the base of the fifth pair of walking legs, while the genital opening of female shrimps is at the base of the third pair of walking legs; fourth, the abdomen of sexually mature female shrimps is swollen, and the abdomen of male individuals is relatively narrow. The selection of broodstock is generally in September-October of the previous year or March-April of the current year. When selecting, select individuals that are over 10 months old, weigh 30-50 grams, have a standard body shape, are strong, have complete appendages, are free of disease and injury, and have strong vitality. The ratio of male to female is 2:1. Generally, the broodstock selected in the previous year can be smaller in size, while the broodstock selected in the current year should be larger in size.
