CATDOLL : CATDOLL: Can frogs shrink? Can ladybugs shrink?

1. Can frogs shrink their bones?

able.

Frogs are cartilaginous animals and can shrink.

The change in physiological structure is a defense mechanism of the frog itself. There is a lot of connective tissue on its hind legs, where the sharp claws of the sturdy hair frog are hidden. When the sturdy hair frog is attacked, the tip of the claw will pierce the toe pad and protrude from the bottom, looking like a cat's claw. But the difference is that the frog's claw is just bone, not covered with keratin. There is no retracting muscle inside the frog's foot, so when the muscle is relaxed, the claw will automatically slide back into the toe.

2. Can ladybugs shrink?

Ladybugs don't shrink.

The elytra of newly emerged adults are very soft, light-colored, and without markings. The markings on the elytra gradually appear, sometimes over minutes, hours, or even days or weeks. In the wild, the lifespan of ladybugs varies. Some species with longer dormancy periods can live for about a year, and two years is common. If there are no suitable conditions for laying eggs, some adults can spend the second winter without laying eggs.

Add seasonings to make it taste good, mix it with a little dry starch, fry it until crispy and then remove it from the pot.

4. Technology for breeding large fish with shrunken bones?

1. Fish fry cultivation:

The shrunken bighead carp (deformed silver carp) is usually cultivated in fish fry farms until it reaches a size of 9 days or above before farmers take it back to the pond for breeding. The general size is 9 to 11 days, which has a certain guarantee for the survival rate of farmers in the pond.

(1) Fish pond conditions

The water inlet and outlet should be convenient and equipped with escape prevention facilities. The water quality should be excellent and free of pollution and poison. Farms with conditions can maintain the water temperature between 15 and 30 degrees Celsius and the dissolved oxygen level above 4 mg/L.

(2) Stocking density of silver carp fry

At the ninth day, the stocking density can be 8,000-10,000 fish per mu. When the average growth reaches 11 days, the density is reduced to 3,000-5,000 fish per mu.

(3) Starter feed and feeding

The starting food for the shrunken silver carp is zooplankton, and egg yolk and zooplankton can also be used together. The best starting food for the shrunken silver carp is copepod sword water fleas. If sword water fleas are fed, the time of feeding must be mastered to prevent the sword water fleas from breaking the yolk sac of the fry and causing a large number of fry to die. The daily feeding frequency is preferably 4 to 8 times. Feeding is also required at night in the cultivation room. The amount should be slightly surplus. The initial feed needs to pass through a 60-mesh sieve to screen out large individuals and harmful aquatic insects. In the later stage, after domestication, artificial compound feed can be eaten. Domestication is generally carried out by stopping feeding or purifying water for 8-15 days before high-protein feeding, and the food intake is about 3 to 5% of body weight. Shrunken silver carp will not actively forage before domestication, and the loss part during feeding is larger. Shunde Aquatic Products Station experimentally used high-protein (more than 40%) feed with rice bran and water to sprinkle on the 3-inch cultivation stage, which has achieved very good results.

(4) Daily management and matters needing attention

Daily management requires sewage disposal, window screen cleaning, and detailed record keeping. The size of the fry should not exceed two positions. Too large a difference in size leads to uneven nutrition.

2. Fish breeding stage:

(1) Pond requirements

A pond with a water surface of 3-5 mu, a water depth of 1.5-2 meters, and convenient water inlet and outlet is preferred. Each pond should be equipped with a 1.5-kilowatt aerator. Before entering the pond, water should be brought to clean the pond. 150-200 kg of quicklime per mu should be used to kill miscellaneous fish, aquatic plants, etc. The water temperature of the pond can be 2-37℃, and the most suitable is 22-32℃.

(2) Adding fertile water to the pond

One week before the pond is opened, fertilization should be done to cultivate good water quality. The general fertilizer is manure (400-500 kg/mu) and chicken and cow dung. After 3 days, soybean milk should be spread in the pond at a dosage of 5 kg/mu. Before opening the pond, the fish should be fished out again with a water net to remove tadpoles and debris. The temperature difference between the water in the pond and the water in the fish container should not exceed ±3℃. The operation should be carried out in the evening.

(3) Reasonable sparse breeding

The main breeding method is single breeding, and a small amount of bottom fish and herbivorous fish, such as grass carp and yellow catfish, can be used at the same time. The stocking density is preferably 500 to 800 per mu. During the breeding process, in addition to fertilizing (such as using organic fertilizers and chemical fertilizers) to cultivate the water body, it is also necessary to feed soybean milk (2 kg/mu), cake meal and floating wheat flour, bran or special granular bait, Shunde Aquatic Station uses shrimp feed and rice bran to feed to more than 1.5 catties, and then acclimate to use 1# particle size and protein and more than 38 floating feed. When the weight is more than 3 catties, use 2# protein and more than 38 floating feed. It is always required to maintain the requirements of water quality, richness, liveliness, tenderness and freshness.

(4) Strengthen management

Insist on patrolling the pond every day and keep careful breeding records.

(5) Shrinking bighead carp has few diseases. Generally, fish species larger than 15 to 20 cm rarely die. When they are young, they may have parasitic and bacterial diseases. Occasionally, fish diseases are mainly trichodina and trematodes, which can be treated with potassium permanganate or trichlorfon. For bacterial diseases, antibiotics are often used to soak the fish at a concentration of about 4×10-6. After treatment, the fish can be directly released into the reservoir or continue to be cultured in the pond.

6. How to catch the shrinking fish?

The shrimp is a relatively common freshwater fish, mainly distributed in rivers and lakes in southern China. It generally likes to live in places with dense aquatic plants and slow water flow. Here are some fishing methods and techniques for shrimp:

1. Choose the right fishing gear: Generally speaking, the shrunken fish is relatively small, so you need to use a small fishing rod and thin line. Common fishing gear includes: float, lead sinker, fishing line, hook, etc.

2. Choose the right bait: The mouth of the constrictor fish is small, and it generally likes to eat small aquatic insects, earthworms, grasshoppers, etc. You can choose these small baits for fishing.

3. Choose a suitable fishing spot: Shrinkfish like to live in places with dense aquatic plants and slow water flow, so you can find fishing spots in these places. At the same time, you need to be careful to avoid areas where large fish appear.

4. Pay attention to adjusting the depth of the fishing group: Constrictors are more sensitive and easily disturbed by the outside world. When fishing, you need to pay attention to adjusting the depth of the fishing group and maintain a quiet environment to avoid disturbing the fish.

5. Pay attention to the timing of reeling in: When you feel the float moving, you need to reel in the rod in time to avoid excessive pulling that may cause the fish to escape. At the same time, you also need to pay attention to controlling the speed and strength of reeling in the rod to maintain a stable state.

7. What does the shrinking fish eat?

The bighead carp likes to live in fertile water bodies, which is just in line with the characteristics of fertile water bodies. The bighead carp generally lives in the upper layer of the water body, moves relatively slowly, has a docile temperament, is easy to catch, and can almost be caught in one net in the pond. The bighead carp has strong disease resistance and rarely gets sick. It mainly feeds on plankton, especially zooplankton, and also eats a small amount of phytoplankton and other small suspended matter. Under artificial breeding conditions, it also eats artificial feed such as bran, soaked bean cake and navel cake.

8. What are the techniques for breeding bighead carp?

1. Choice of pond

The area of ​​the fish pond for breeding bighead carp fry is 1/151/15hm2, the depth is about 1.5 meters, the embankment is firm and leak-proof, the bottom of the pond is flat and has a moderate amount of silt, and no aquatic plants; the fish pond faces the sun and has sufficient sunlight. And it must be cleaned before stocking.

2. Seedlings stocking

In the past, the stocking specifications of lakes and reservoirs were generally large-sized fish of about 13.2 cm. Under modern technical conditions, large-sized fish of 0.15-0.5 kg/tail or even 1.0 kg are required. In addition, attention must be paid to breeding recommendations and disinfection to ensure the growth quality of the fish. At the same time, sufficient stocking time should be given to promote the growth of the fish with better quality.

3. Water Quality Management

The quality of water is the key to the success of raising bighead carp. During the process of raising bighead carp, we should always pay attention to the changes in water quality. We should often decide whether to change the water according to the changes in water color, transparency, the cleanliness of the bighead carp's shell and gills, and the degree of bottom pollution. At the same time, we should also promote its growth in a place with sufficient salinity and fresh water.

4. Feeding Methods

If you want to get a higher yield, you must feed. The bait can be wheat bran or bran, but the effect is not as good as special bighead carp feed. Bighead carp feed is composed of cake meal, bran, fish meal and additives. The nutritional value is required to be higher than that of grass carp feed, similar to omnivorous fish such as carp and crucian carp. It is generally made into powder and contains more than 30% crude protein. When the water temperature reaches 15℃ in spring, first slowly feed it artificially in the upwind area, which is similar to the training of other carnivorous fish, but the time may be slightly longer. When the water temperature is above 26℃ in summer and autumn, it is the fastest growing season for bighead carp. It is necessary to strengthen feeding in combination with water quality management.

After the training of the bighead carp is successful, the feeding amount is generally 1% to 3% of the body weight of the fish in the pond, and it is fed 2-3 times a day. When feeding, they usually swim around the feeding ground in groups, with their heads half exposed above the water surface, swallowing the feed into their mouths along with the water. Their overall performance is not as fierce as other feeding fish, but relatively gentle, and the feed coefficient is generally between 2 and 3. Some people feed the bighead carp with expanded microparticle floating feed. Although the feed quality is very good, the effect is not ideal. The fish grow unevenly, the size is very different, and the feed coefficient is very high, and the group yield is also average.

9. Technology for breeding shrunken fish?

When breeding shrimp, you need to build a fish pond of 8-10 mu, with a water depth of 1.5-1.8 meters and a bottom mud thickness of 20-30 centimeters. The water quality must be good and pollution-free. Thorough disinfection must be done before stocking, and attention must be paid to density. For fish of 5-10 cm in size, 500 fish should be stocked per mu. Feeding should be done throughout the day, and the feeding rate should be adjusted according to the season, weather, and dissolved oxygen. In addition, attention should be paid to disease prevention and control.

10. How to make fish hotpot?

Ingredients:

500 grams of shrimp and 500 grams of fish tofu.

Excipients:

Ginger, scallions, onions, and red peppers.

seasoning:

Salt, pepper, cooking wine, light soy sauce, dark soy sauce, sugar, pepper, and soybean paste.

practice

1. Start preparing the ingredients

Prepare a shrunken fish, which has been slaughtered in advance, chop off the fish head, and cut the fish meat into 1 cm wide pieces. After cutting, wash it again to fully remove the blood on it, squeeze out the water and set aside.

2. Marinate the fish pieces

Prepare a piece of ginger and cut it into thin strips. Prepare a section of green onion and cut it into horseshoe slices. Put it together with the fish pieces, add a spoonful of salt, a spoonful of pepper, and a little cooking wine to remove the fishy smell, mix it evenly with your hands and marinate for 10 minutes.

3. Start preparing the auxiliary materials

Prepare an onion, cut it into slices and place it on the bottom of the casserole. Prepare an appropriate amount of fish tofu and cut it in half. (You can choose the meatballs you like)

Prepare a few cloves of garlic and flatten them. Prepare a piece of ginger and cut it into slices. Put all of them in a casserole, place the marinated fish pieces around the casserole, and put the fish head in the middle for later use. Prepare a red pepper and cut it into small pieces for coloring. Prepare a small bowl, put 30 grams of light soy sauce, 3 grams of dark soy sauce for coloring, 10 grams of white sugar, 3 grams of pepper powder, and then pour in a little cooking wine to remove the fishy smell, and stir well.

4. Start frying the sauce

Heat oil in a pan, moisten the pan thoroughly, pour out the hot oil and add cold oil, pour in red pepper and stir-fry for a while, add three spoons of soybean paste, stir-fry until the sauce aroma comes out, then pour in a little water, after the water boils, pour the sauce evenly on the fish, then pour in the prepared bowl ingredients, add an appropriate amount of water, the height of the water should be level with the fish. The amount of water should be level with the fish, so that the fish is more flavorful and not easy to stick to the pan; the sauce is salty, so there is no need to add salt.

Bring the soup to a boil over high heat, then simmer over medium-low heat for 15 minutes. After 15 minutes, the tender and delicious braised fish can be served.
