CATDOLL : CATDOLL: How to artificially breed horseshoe crabs? How to quickly cook fish?

1. How to artificially breed horseshoe crabs?

Horseshoe crabs cannot be bred artificially.

Horseshoe crab is a national second-class protected animal. It is a marine arthropod belonging to the Xiphonyti order of the class Limulus. It is shaped like a crab, with a bluish-brown or dark brown body covered with a hard shell. It has four eyes, two of which are compound eyes. There are two small eyes of 0.5 mm at the front end of the cephalothorax, which are most sensitive to ultraviolet light and are only used to sense brightness. There is a pair of large compound eyes on both sides of the cephalothorax.

Although horseshoe crabs can swim by flapping their gills with their backs facing down, they usually arch their bodies, burrow into the mud, and then use their tail sword and the last pair of legs to propel their bodies forward.

2. How to cook fish quickly?

"Fewer ingredients, shorter time, and better taste", steamed seabass is a good choice for lazy foodies and beginners who love cooking. Steaming can ensure the original flavor of the ingredients. At the same time, seabass has a higher edible value. Eating seabass is a nutritious food that can nourish the body without causing overnutrition and obesity. It is a good product for fitness, blood, spleen and qi, and health.

Steamed sea bass

Main ingredient: Sea bass

(one), steamed fish soy sauce

(3 spoons), cooking oil

(appropriate amount), cooking wine

(appropriate amount), soy sauce

(1-2 spoons), sugar

(a little), onion and ginger

(appropriate amount), salt

(Personal taste)

Steps:

1.

Prepare ingredients: clean the sea bass (be sure to clean the blood, otherwise it will affect the taste), cut the green onion into sections, and cut the ginger into shreds

2.

Slice the fish a few times, apply salt and cooking wine (yellow wine or beer is fine, I used a bottle of beer once before) and marinate for 10-15 minutes (stuff a little scallion and ginger into the fish belly to enhance the flavor)

3.

Preheat the steamer with water, boil the water and then put the fish in and steam over high heat for about six or seven minutes.

4.

While steaming the fish, you can prepare the sauce: mix light soy sauce + steamed fish soy sauce + sugar and set aside

5.

The steamed fish will have some soup, pour it out. (The soup is a bit fishy, ​​so if you are used to it, you don’t need to pour it out) Spread the shredded ginger and scallions evenly on the fish.

6.

Heat oil in a hot pan and bring to a boil until smoke comes out.

7.

Pour the boiling oil over the fish from head to tail, and quickly pour the sauce in the same way. A nutritious, delicious, refreshing and tasty steamed sea bass is ready.

Kind tips:

1. The soup secreted by steamed fish is very fishy and will affect the taste, so it should be poured away;

2. The green onion and ginger in the fish belly can be kept;

3. The sauce contains salt, and salt is also added when marinating the fish, so no salt is needed for subsequent operations.

In fact, this method can be applied to steaming not only sea bass, but any kind of fish. Also, the temperature of steaming fish is very important. Generally, a fish of about 1 jin should be steamed for 6 or 7 minutes. Remember, high heat! Of course, the fire of each stove is different. Some stoves are not strong enough, so it is estimated that it will not be cooked in ten minutes. I have tried it at my mother's house. As for whether the fish is cooked, first observe whether the fish meat is open, and the fish's eyes will definitely fall out if it is cooked (sigh, I feel so cruel). If you are not sure, poke it with chopsticks. If it is not cooked, you can't poke it at all.

Another thing is to remove the fishy smell from fish. In fact, whether it is wild or farmed fish, they generally have more or less fishy smell. Especially farmed freshwater fish, it is easy to have a strong earthy smell. Therefore, removing the fishy smell is also a two-step process. The first step is to wash the fish thoroughly inside and out. It is best to scrape the fish with a knife. You will find a layer of black mucus being scraped off. Also, the black film in the fish's belly must be cleaned.

4. How to do the injection method in fish immunization? Fish?

Fish vaccination is the best choice for preventing diseases that are difficult to control and often cause huge losses. Vaccines for preventing bacterial diseases on the domestic and foreign markets include formalin-inactivated bacteria and oil-adjuvanted products; in addition, oral vaccines that can be mixed with bait and fed have also appeared on the foreign market. There are monovalent vaccines that only fight against one type of bacteria, and there are also multivalent vaccines that can fight against more than one type of bacteria.

So here's the specific method.

Injection vaccination: When the fish are large enough (average weight of 50 g/tail or more), intraperitoneal injection can be used for vaccination. If the immersion method is used at this time, the number of fish isolated by tarpaulin is small due to the large size of the fish. When anesthetizing, the larger the fish, the greater the risk of self-injury due to stress reaction, so extra caution is required. Subsequently, a small group of fish is scooped out with a net and placed in a container with a higher concentration of anesthetic dilution until the fish are still. When operating on the vaccination table, the fish's head is facing outward and the fish's belly is facing up, and the vaccine (usually 0.1-0.2 ml) is injected into the fish's abdomen. The needle penetrates the abdominal cavity about 0.5 cm. A fully automatic syringe can be used. After the injection, the fish is placed in a temporary holding tank and will recover from the anesthesia after a few minutes.

Immersion vaccination: For this method of vaccination, a large group of fish is separated from the rest of the cage by a tarpaulin and a small amount of diluted anaesthetic is added to tranquilize the fish. Air or oxygen is pumped in continuously during this period to prevent hypoxia. The appropriate dose of vaccine is calculated based on the estimated weight of the fish to be vaccinated (usually 1 litre of vaccine is required for every 100 kg of fish). The vaccine is diluted in seawater or freshwater in a suitable container (a common dilution ratio is 1:10, i.e. 1 litre of vaccine to 9 litres of water). Oxygen may be slowly introduced into the vaccine diluent to reduce stress on the fish. The sedated fish are removed from the tarpaulin, approximately 0.5 kg at a time, to avoid overcrowding or crushing. The water is drained and the fish are placed in the vaccine diluent for a period of time, usually at least 30 seconds. The routine procedure is to place the fish removed from the tarpaulin in a perforated plastic bowl in the vaccine diluent and, at the end of the soaking period, the fish are removed from the vaccine solution and placed in a holding facility.

Finally, let me talk about some precautions

In order to keep the stomach and intestine almost empty during inoculation, the fish should be fasted before inoculation. The smaller the fish and the higher the water temperature, the shorter the fasting time required. Fasted fish have poor tolerance to stimulation caused by handling and are sensitive to anesthetics;

Vaccination is only suitable for healthy fish that have not been subjected to any stimulation. It should not be performed when the fish is sick or has recently been severely handled or subjected to other environmental stimulation.

During immersion inoculation, the temperature difference between the vaccine diluent and the aquaculture water should not exceed 2;

Vaccination must be carried out in a disease-free environment, and the fish can be exposed to the disease or transferred to a disease-prone pool about 2 weeks after vaccination when the water temperature is 15 degrees Celsius. The higher the water temperature, the shorter the time required to produce immunity.

10. What are the characteristics of fish?

There are four main characteristics of fish: they live in water, breathe with gills, swim with fins, and reproduce by laying eggs.

1. Living in water: All fish live in water. Even though some can stay out of water for a short time, they cannot stay out of water for a long time. For example, mudskippers can go ashore to look for food when the tide is low, but they will definitely return to the water before being killed by the sun. The African lungfish stays out of water the longest. During the dry season of the river, they will burrow into the mud and hibernate with a small amount of water until water comes back.

2. Breathing with gills: One of the reasons why fish live in water is that they mainly breathe with gills. Unlike the lungs of terrestrial animals, gills need to be moist to function properly. When water flows through the gill filaments, the blood vessels inside can complete the exchange of oxygen. However, some fish can breathe with the help of other organs, such as loaches can breathe with their intestines, and fish of the family of perch have suprabranchial organs that can obtain oxygen from the air.

3. Swimming with fins: Since fish live in water, they need some means to swim. Fish fins are the helpers of swimming. They are usually divided into five categories, namely pectoral fins, pelvic fins, dorsal fins, anal fins and caudal fins. Some fish also have adipose fins. Different fins have different functions, but they can basically maintain balance. The caudal fin can also provide power and turn, which is particularly important for fish.

4. Reproduction is oviparous: Most fish reproduce by laying eggs, and a few are ovoviviparous. Ovoviviparous looks like viviparous, but it is still oviparous, except that the eggs are not hatched outside, but inside the fish body, so the fish are born small.
