CATDOLL : CATDOLL: What kind of environment is suitable for the growth of the Pomfret?

The Fushou fish was hybridized by the Pearl River Fisheries Research Institute in July 1978 with the Nile tilapia imported from Thailand as the male parent and the Mozambique tilapia as the female parent. The body shape of the Fushou fish is similar to that of the Nile tilapia, and it is gray-green in color. The suitable growth temperature is 20D35℃, and it is mainly suitable for breeding in southern my country. The feeding habits are the same as those of the parents, and the requirements for feed quality are not high. A small amount of concentrated feed with a large amount of roughage can meet the requirements. It can also eat the residual feed debris at the bottom of the pond and in the water, and is the "cleaner" of the pond. It has a strong digestive function and obvious hybrid advantages. It grows faster than tilapia, but slower than Aurelia tilapia. It is currently less farmed.

The Chinese abalone is mainly known as tilapia in Taiwan and is commonly known as African crucian carp or tilapia in my country. It is native to Africa and has excellent adaptability and strong reproductive capacity.

This fish was introduced to Taiwan from Singapore by two Taiwanese people, Wu Zhenhui and Guo Qizhang, who were conscripted to serve in the Nanyang Army. Later, the Taiwanese named the fish Wu Guo after their surnames.

The male Pomacea carp will dig a round bowl-shaped nest at the bottom of the pond, allowing the female fish to enter first to lay eggs, and then the male fish to enter for fertilization. The female fish then carries the fertilized eggs. The cost of releasing Pomacea carp fry is very low, and they will reproduce endlessly on their own once released.

The Fushou fish is afraid of cold and often has difficulty surviving the winter. When the temperature is low, it will hide in its den and not come out, so it is not suitable for fishing in winter. When the water temperature is between 25 and 30 degrees, it is active and active at dawn and dusk. Its peak activity is in the morning and dusk, when it swims shallowly and close to the shore. At noon, it hides in the center of the pond. The best time to fish for it is in the evening of spring and autumn, and before 10 am in midsummer.

The Fushou fish is very aggressive in grabbing bait, and is known as the best entry-level fish for beginners. When making nests, it is close to the shore, and it also takes bait close to the shore where plankton and organic matter are rich. Therefore, it is more advantageous to use a hard-tuned fishing rod to fish for this fish. Generally, a 9-foot, 12-foot, or 15-foot 37-tuned hand-held rod is used, and a 28-tuned rod is also acceptable. The main line is 1.2, the sub-line is 0.8, and the hook is a small Ise Ni.

There are many types of mullets, so their feeding habits are also different. Common mullets are relatively omnivorous, but the bait with meat powder as the main ingredient is the most effective. When fishing for this fish, add shrimp powder and a little salt to the bait (it lives in fresh water and must take in enough salt to balance the osmotic pressure in the body and maintain normal physiological functions). It tends to feed on animals, so vegetarian bait is not very attractive to it.

Although the Taiwan fishing method is popular in mainland China, it is necessary to explore it in depth to understand its essence. In the deeper fishing theory, it is necessary to understand the nature of the fish as the starting point, so as to achieve "know yourself and know the enemy, and win every battle." It is not about blindly using products enhanced by advertisements, but with high-quality fishing gear and superb fishing skills, and keeping the natural laws in mind is the way to fish.

The mullet is a ferocious fish by nature. Because it is artificially bred and the fishing is booming, this kind of putting a large number of fish into the pond and fishing in a leisurely way is one of the laws of nature, but it also creates a kind of fun. There are many levels of fishing for mullets, such as love activities, couples to enhance their relationship, etc. There are also professional methods. When the professionalism is extended to the limit, the method of fighting pools naturally arises. For this and professional fishing level, anglers must have all-round knowledge, concepts, functions, etc., and their expectations should be based on expanding the human mindset.

Fushou fish were originally a summer fishing species. The current artificial breeding allows them to open their mouths to feed even in winter, but the change in water temperature will cause their desire to feed to be very low. Therefore, there are two types of fishing methods: cold water Fushou and warm water Fushou. Winter Fushou fishing is a forced fishing method. Since there is too much content to go on, it will be introduced in stages.

Since it is impossible to describe the complex and highly technical professional field in a short article, the content of the technique of adjusting the buoyancy of the float should be briefly introduced. Whether fishing for Fushou in a leisure pool or a competitive pool, the most annoying thing is that the space bean is easy to slide when pulling fish frequently, so choosing a space bean with good quality is the best choice. As for the main line and the sub-line, it is even more of a piece of cake. It is more reassuring to choose a product with stable quality and high grade.

The float socket should be a product with low elasticity to avoid the float being separated from the fishing group halfway through the fishing process. Because readjusting the speed of the float will waste precious time in competitive occasions, especially in competitive pools. The impact on the ranking is very obvious. To increase the speed of fishing, products with elastic components should be used, which can buffer the disadvantages of sub-line breakage and quickly replace the sub-line. As for the hook, it should be handled according to the leisure pool or the competitive pool. Using a hook with a thin hook diameter will pierce the fish mouth faster, but as the fishing time increases, the sharpness of the hook will decrease faster, so thin bone hooks should be used in leisure pools; in competitive pools, use thicker hooks instead.

Fish bait is very important, especially in the competition pool, and it is also the main reason for failure. In Taiwan, there has been frozen bait for longevity fish for a long time. I believe everyone will notice that it spoils quickly. Because animal bait contains a lot of protein, its characteristic is that it decomposes very quickly, such as shrimp skin and fish meat. The fish's sense of smell is unexpectedly sharp, more than 10,000 times that of humans. And fish have taste buds all over their bodies, just like the human tongue. They don't need to put food in their mouths, but rely on taste detection, and then the edible is transmitted through the nerves, and then they open their mouths to eat. Especially when the float swings up and down, fails to sink cleanly, and has two or half eyes, it is very likely that it is using a part of its body to test.

In order to avoid olfactory rejection, we must first remove the ammonia in the bait (ammonia is resistant to the decomposition of protein, is one of the important organic substances of urea, and is fatally harmful to most aquatic organisms). The ammonia in ammonia will make it difficult for fish to get oxygen, so we must understand where the ammonia comes from in order to remove this ingredient.

Now, we still have one thing missing, that is, high-protein foods are easily converted into ammonia, a poisonous gas, under high temperatures, especially aquatic organisms that contain a lot of protein, such as Antarctic shrimp and red-tailed green shrimp. This is why red-tailed green shrimp must be boiled and then dried in the sun before it can be stored for a long time! Friends who have experienced rock fishing know that Antarctic shrimp will turn black within an hour after being taken out of the freezer and exposed to the sun. This is the effect of self-decomposition, the protein rots and turns into ammonia; the fishy smell is unbearable even for humans, let alone fish with a keen sense of smell!

It is very appropriate to use redtail green as the main bait, because it is an important link in the food chain in the water, just like krill (Antarctic shrimp) in cold waters; its nutrients can provide life for most of the life forms in the sea, and in fresh water, it is regarded as a precious bait by anglers. However, the best redtail green is frozen freshly, followed by frozen redtail green and shrimp skin. Because the dried redtail green and shrimp skin absorb water and dry at low temperatures, there is also the possibility that the protein will decompose into ammonia, a toxin. Even if refrigerated, it must be kept at minus 20 to 25 degrees to maintain freshness. If it is not kept at this temperature, once the refrigeration time is too long, the shrimp body will turn from transparent to yellow, and then to red, and finally to black. At this time, take it out to defrost, and the smell emitted after melting indicates that the protein has decomposed into ammonia.
