1. How to promote the sexual maturity of lobsters?

To make crayfish reproduce quickly, we must understand their reproduction habits and adopt targeted methods. The reproduction of crayfish includes four stages: sexual maturity, mating, ovulation and fertilization, and egg incubation. Each stage has different requirements for breeding and environment. As long as these requirements are met at each stage, the reproduction of crayfish will be accelerated.

1. Use large and early seedlings to accelerate the sexual maturity of crayfish. When stocking, use large and early seedlings, which have an earlier growth period than ordinary shrimp seedlings and also reach sexual maturity earlier. June to August is the peak period of sexual maturity for crayfish. You can intentionally lower the water level and increase the water temperature to promote the red and hardening of the crayfish shell, stimulate the development of the crayfish gonads, and accelerate sexual maturity.

2. Reduce interference, facilitate hole digging, and speed up the mating of crayfish. From July to September, sexually mature crayfish begin to mate naturally, and mating occurs in the shallow water at the bottom of the pond or in the hole. Try to reduce night operations and interference from natural enemies to create a quiet environment for crayfish to mate. At this time, some crayfish will dig holes to escape the heat and complete mating in the hole. The water level should be lowered appropriately to allow more places for crayfish to dig holes.

3. Strengthen nutrition to promote the development of the female shrimp's ovaries. After crayfish mate, the sperm of the male shrimp is stored in the female shrimp's body. The female shrimp's ovaries need to mature before they can ovulate and fertilize. At this time, it is necessary to increase the feeding amount so that the female shrimp can get sufficient nutrition to speed up the development of the ovaries and ovulate as soon as possible. The difference during this period is very large. Female shrimps that develop early can lay eggs in autumn, while female shrimps that develop late will delay laying eggs until the spring of next year. Therefore, if you want lobsters to reproduce quickly, the majority of female shrimps must lay eggs in autumn.

4. Maintain the water temperature to promote the hatching of shrimp fry. After the fertilized eggs are discharged from the mother shrimp, the shrimp fry are hatched mainly by the water temperature. If the temperature is high in autumn and winter, the shrimp fry will hatch quickly. If the temperature is low, lower the water level and use sunlight to increase the water temperature to promote the hatching of fertilized eggs.

The above measures to speed up the reproduction of crayfish are easier to implement in rice field shrimp farming, but difficult to do in pond shrimp farming, so rice fields produce seedlings earlier than ponds. Since crayfish farming now integrates breeding and farming, when we sell shrimp, we should try to keep enough shrimp for breeding, and catch the small ones and keep the big ones, so as to ensure that early and large seedlings can be produced next year.

2. How to promote the sexual maturity of goldfish?

Goldfish grow and develop very quickly. Generally speaking, they reach sexual maturity and can reproduce after half a year.

Goldfish are not very demanding in terms of the environmental conditions they need to grow. Under domestic conditions, goldfish can grow and mature smoothly not only in a large fish tank, but also in a smaller aquarium with a water depth of 30 cm and a volume of about 20 kg, if the stocking density is appropriate.

The three main factors that affect the speed of goldfish development and the early or late sexual maturity are nutrition, water temperature and date. In order to make goldfish develop well, we must do more work around these three factors. In daily feeding and management, we must pay attention to keeping the water fresh, the bait nutritious and palatable, and feeding properly.

Especially before winter, you should consciously choose bait with high protein and fat content. After wintering, goldfish will start to eat when the water temperature rises to about 10℃ in spring. You should pay attention to feeding them carefully, move the fish container to a warm environment, and extend the sunshine time as much as possible. These are important conditions for goldfish to grow fast, reproduce early, and have strong offspring.

3. How to promote the sexual maturity of bullfrogs?

Bullfrogs must be cooked thoroughly, otherwise they will be filled with parasites that are harmful to the human body. The best sign of a cooked bullfrog is that the bullfrog meat and its bones fall off naturally.

4. Feed that promotes parrot reproduction?

Budgies like to eat shelled millet the most. Although they can eat rice, they don't like it. When raising budgies, millet and barnyard grass can be used as the main food, and then some sesame seeds or perilla seeds can be prepared. Of course, the amount of such food should not exceed 10%. In addition, in order to ensure that the budgies can take in enough nutrients in their diet, the breeder can also prepare some fresh green vegetables and inorganic salts. For example, cabbage, rapeseed, bone meal, oyster meal, etc. are all fine.

Studies have found that budgies are tolerant to roughage, so more roughage can be prepared during breeding, but not too much concentrated feed. This can effectively prevent budgies from becoming obese due to fat accumulation, while ensuring that budgies can lay eggs and reproduce normally.

6. Why is wheat the preferred feed for fish energy feed?

Wheat is a good energy feed for ruminants such as cattle and sheep. It should be crushed or flattened before feeding. The amount in the feed should not be too much (controlled below 50%). It should be mixed with large-volume feed (such as grass meal), otherwise it will easily cause rumen and intestinal colic. The starch contained in wheat is soft and sticky, so wheat and its second flour are better than any other grains as fish feed. Therefore, wheat is the first choice for fish energy feed.

7. Creation and magic fish feed formula?

Creating a magic fish feed formula requires considering the nutritional needs of magic fish and the particularity of magic elements. Here is a sample formula: Ingredients: 1. Magic plant powder: It can be extracted from plants with magic power and contains rich magic energy and nutrients. 2. Seaweed powder: It is rich in minerals and vitamins, which helps to meet the nutritional needs of fish. 3. Fish food supplement: It contains necessary vitamins, minerals and proteins, which can improve the immunity and physical health of fish. 4. Fish or shrimp powder: It provides high-quality protein, which matches the feeding habits of magic fish. Recipe: - 1 cup of magic plant powder - 1/2 cup of seaweed powder - 1/4 cup of fish food supplement - 1/4 cup of fish or shrimp powder Preparation method: 1. Mix all the ingredients in a dry container and stir well. 2. Transfer the mixture to a sealed container and make sure to store it in a dry, cool place. Usage: Feed the fish with an appropriate amount of magic fish feed formula every day. Adjust the amount according to the size and appetite of the fish.

8. What are the effects of different fish feed types on fish growth?

If it is the same series of feed, for example, from the fingerling stage to the rearing stage, and then to the adult stage, there is no problem using the same series of feed.

However, if the nutritional proportions of fish from different series or different manufacturers are generally different, it is likely to lead to nutritional deficiencies, such as vitamins, methionine, lysine, etc. The lack of these essential nutrients will cause mild cases of slow growth and decreased immunity of the fish, and severe cases will cause deficiency syndromes and developmental deformities.

9. What are the fish feeds for Creation and Magic?

There are only two types of bait in the Creation and Magic bait recipe. Crayfish and wheat feed can be made into crayfish bait, and hairy crab and wheat feed can be made into hairy crab bait. Other baits are small earthworms, big earthworms, and earthworm kings. These earthworms are obtained randomly during the process of collecting clay.

10. Why can moderate application of fertilizers increase fish production in ponds?

Moderate application of chemical fertilizers in fish ponds can improve water quality and nutrient content, which can increase fish production.
