Chapter 164 162. Fish Steak 2
Crayfish are extremely adaptable and have a wide range of suitable growth temperatures. They can grow and develop normally when the water temperature is 10-30°C.It can also withstand high temperatures and severe cold, can withstand high temperatures above 40°C, and can survive the winter safely at temperatures below -14°C.

Crawfish grows rapidly. Under the condition of suitable temperature and sufficient bait supply, after more than 2 months of breeding, it can reach sexual maturity and reach the standard of commercial shrimp. Generally, male shrimp grows faster than female shrimp, and commercial shrimp The size is also larger than the female shrimp.

Like many crustaceans, the growth of crayfish is also accompanied by molting. When molting, they usually look for hidden places, such as in aquatic plants or under plant leaves.

After molting, the maximum weight gain can reach 95%. Generally, 11 times of molting can reach sexual maturity, and sexually mature individuals can continue to molt and grow.

Its lifespan is not long, about 1 year.However, under conditions of food shortage, low temperature and relatively drought, the life span can be up to 2-3 years.

During the breeding season, they like to dig burrows.The cave is located about 20 centimeters above the water surface of the pond, with a depth of 60 centimeters to 1.2 meters. There is a small amount of water in it to maintain humidity. The cave entrance is usually sealed with a mud cap to reduce water loss.At night in summer or after a heavy rain, it has the habit of climbing ashore, crossing dikes and entering other water bodies.

Crayfish are omnivores. In terms of eating habits, crayfish prefer to eat mud at the bottom of the river, and they like to eat small dead fish or other aquatic organisms.

It mainly eats plants, including small fish, shrimps, plankton, benthic organisms, and algae.The body's astaxanthin content is positively correlated with its ability to withstand harsh external environments. That is to say, the higher the body's astaxanthin content, the stronger its ability to withstand harsh external environments.Crayfish cannot produce astaxanthin themselves. It mainly obtains astaxanthin through the food chain-edible microalgae, etc., and continuously accumulates it in the body to produce super antioxidant capabilities.

Astaxanthin can effectively enhance the ability of crayfish to resist harsh environments and improve reproductive capacity.

Therefore, astaxanthin is a strong guarantee for the tenacious vitality of crayfish. When crayfish are lacking these astaxanthin-containing microalgae, it is difficult to survive.This also brings some illusions to people's understanding: crayfish must live in a dirty environment.

In fact, crayfish can also live in very clean water, but most of the places where crayfish appear are relatively polluted water, because there are more food in it, which leads people to think that crayfish are relatively polluted. And they can have parasites.

In fact, there are no parasites on the crayfish raised in the clean water of Wangquan, and they can be eaten safely and securely, including the crayfish brains of these crayfish.

Afterwards, Li Hua took his boss for a stroll, where Australian lobsters and abalones were raised, and finally, they came to a hanging place.In front of rows of things, Li Huazi's thing said to his boss: "Boss, these are the oysters for me and Mengyang."

Oysters are animals of the family Oysteridae and are the largest cultivated shellfish in the world. They are one of the most stress-resistant aquatic animals.

It is mainly distributed in temperate tropical seas. It sticks to other objects with its shell and feeds on microscopic algae and organic debris in the ocean.As a marine cultured shellfish, oysters not only have delicious meat, but their meat and shells can be used as medicine and have high medicinal value.

Oyster is a cosmopolitan shellfish. More than 100 species have been discovered and are produced in almost all coastal countries around the world.

Most of the oysters in Japan are the same as those in China. Oysters in Europe and the United States mainly include edible oysters, American oysters, and European oysters, and their total output ranks first in shellfish.The Chinese Han Dynasty began to insert bamboo to raise oysters, and it has a history of more than 2000 years.

Our oysters can be eaten raw. They are your more expensive oysters. One can be sold for tens or hundreds of dollars.If you don’t wear it all the time, I’ll give you a try right now.

"No, no, I don't want to eat this raw oyster, I'm afraid I'll have diarrhea after a while."

"Okay then, boss, come over and have a look, we still have scallops and shrimps here."

Scallops are animals of the scallop family of the pearl oyster order.Its shell is fan-shaped in appearance, but the hinge line is straight, and the two ends of the hinge have wing-like protrusions; the size is about 2.5-15 cm (1-6 inches); the shell is smooth or has radial ribs, smooth ribs, scales or knobs Shape, bright red, purple, orange, yellow to white; the lower shell is lighter and smoother; there is a large adductor muscle.It is distributed in all oceans of the world, inhabits shallow seas from the low tide zone to hundreds of meters, attached or free-living, and mainly feeds on mayfly algae.

There is a movable trapezoidal frontal horn plate in the center of the front edge of the Pipi shrimp's head and breastplate. There are movable eye segments and antennal segments in the front. The abdomen is wide. Finally, there is a wide and short caudal segment. There is a central ridge on the back and a ridge on the rear edge. Strong spines.It lives in many caves, has a ferocious temperament, sharp eyesight, and is good at swimming. It is widely distributed in Russia, Japan, China, the Philippines, the Malay Peninsula, and the Hawaiian Islands.

In fact, we Cantonese prefer to call this Pippi shrimp Shrimp Gu.

I like Daiyu.After seeing these things here, my boss said: "Boss Haole will only have some Australian lobsters collected by relatives, and there will be nothing else."

"Wow, your stuff is not bad, no, why do you still have a small fish steak here? What's in it?"

"Hey, boss, don't you remember? Didn't you ask me to raise those golden foxes for you?"

"These are the golden foxes you asked me to raise. By the way, you told me a few days ago that you had one. Brother, you want to buy a golden fox, right? If you hadn't come to buy it some time, we would have caught it ?"

"No, no, after we go out to sea and send you back a row this time, we will fish out the golden fox and return it directly to him at the dock."

"Because that gold fox was auctioned for a full 6000 million yuan. This thing is very expensive now. If I sell this one to my friend, I can get 3000 to [-] million yuan."

"Wow, is this thing so expensive? Then we have seven left, not six, two for your friend and one for the auction. And this one for your friend. After the sale, we In fact, there are only five left, let’s hold on to these five and auction one.”

"Take your time. With the system, these fish can't die. It's much better. Don't talk about it now."

"Okay then, let's make the fish first, or let's chat while we make the fish."

After a few people discussed it, they all went back to bed, and it was still the same.

Luo Jinshuo ran alone to the driver's cab of the bed to sail the boat. The other two people were sitting in the stern of the boat chatting.
