Because the crayfish is rare, so it is more expensive.
Because the living environment is so cold, deep-sea Antarctic crayfish grow particularly slowly, and the ones we eat are all about 15 years old. Therefore, the New Zealand government strictly control the fishing quota of Antarctic crayfish, less than 1,000 tons per year, the global supply is extremely short.
Antarctic deep-sea crayfish are easy to cook, and are suitable for Chinese, Japanese and Western cuisine. Whether it's sashimi in Japanese, seared, steamed or braised in Chinese, or grilled or baked in Western style, the Antarctic crayfish is uniquely delicious.
However, such a delicacy, too complicated cooking methods, but the main focus. Chilled sashimi, with its tender, elastic meat and soft, sweet taste, can fully reflect the inherent freshness and flavor of New Zealand's Antarctic crayfish without any seasoning.
Crayfish feeding skills:
1, pay attention to the density
Before feeding crayfish, first of all, we must choose a good shrimp tank, and plan to feed the density, as well as whether or not to mix other ornamental shrimp. The crayfish is more aggressive ornamental shrimp, the crayfish has a strong sense of territory, if you do not want to raise their own crayfish often fight and injury, it is best to reduce the breeding density.
2, tank aquascape
Establishing a good ecological environment is a critical point of keeping crayfish, crayfish like to live in the sand and gravel, so in the shrimp tank inside the bottom of the sand, you can use the right amount of mafia, coral sand and other materials to pave the bottom. You also need to put in the sunken wood, rocks, water plants, etc., to give the crayfish hiding and feeding place.
3, reasonable feeding
The food that crayfish can eat are red worms, vegetables, plentiful shrimp, etc. The red worms are highly nutritious, and can be used as the staple food of the crayfish, so that the crayfish can grow faster and more robust. Vegetables are generally recommended celery stems, spinach leaves can also be fed, but it is easy to pollute the water and not easy to clean up.
4, regular maintenance
Regular water changes, clean up the filtration system is very important, in the feeding of crayfish must pay attention to the observation of the water quality, but also regularly clean up the residual food in the shrimp tank, if the shrimp tank has too much feces, but also to clean up properly to avoid the deterioration of water quality, resulting in the death of crayfish.
