CATDOLL : CATDOLL: Can fermented soy milk be used to feed dace?

Can fermented soy milk be used to feed dace?

Fermented soybean milk cannot be fed to dace fish. Fermented soybean milk easily produces spoiled soybean dregs, which will cause dace fish with weak disease resistance to eat, causing mild illness or even death, which is seriously harmful to the health of dace fish. Dace, also known as native dace, belongs to the carp family. It has keratin scales all over its body, no teeth, and is rich in protein. It lives in rivers in the south with higher water temperatures. It is one of the main freshwater farmed fish species in southern my country and is afraid of cold. In ancient myths and legends, Shennai Bi dace is a mermaid with a human face and a fish body, also known as Lingyu.

What are the little fish in the river called?

Question 1: What are the small fish that are abundant in the river called? The most common fish is called [white fish]

Chinese aliases: strip, minnow, fish, white minnow, white R, blue knife fish, swimming minnow, green scale fish, sharp mouth, floating silver carp, meal strip, meal fish; Habitat depth: 0 - 10 meters.

Primary freshwater fish. Common fish at low altitudes. Likes to live in groups in the upper water layers of streams, lakes and reservoirs. Mainly feeds on algae, but also on higher plant debris, crustaceans and aquatic insects. Especially likes to eat small shrimps in the river. Has strong reproductive capacity and adaptability, can tolerate relatively turbid waters. Maximum body length: 30cm.

There are at least three reasons why white stripes "shine white": one is the weather; the second is the water; and the third is the fish. White stripes swim in the water, and as they swim, they turn over and are illuminated by the sun. The silvery scales of the fish become silvery, and with the clarity of the water, they appear as a ball of white light. White stripes usually die after being out of water for about 10 minutes. Because white stripes die immediately after being out of water, you need to bring a small bucket with you when you go fishing. The higher the temperature, the less resistant they are to life, making it difficult to keep them in a tank, and they tend to jump.

Question 2: What are the small fish in the water? 1. Observe fish by bubbles. Bubbles are bubbles that fish produce when they breathe, forage, touch the soil, or spit out from their mouths. Bubbles are important signs that reflect the direction, species, quantity, size, and density of the fish's floating. Observe fish by bubbles, and anglers can get underwater information. Crucian carp bubbles: The bubbles are small and dense, two or more bubbles appear at a time, and they are basically the same size. Sometimes two bubbles, one large and one small, appear, and the small bubble follows the large bubble. The size of the bubble determines the size of the crucian carp. If the large bubble is as big as a pea, the fish is about half a catty or more. Carp bubbles: The bubbles form a group, and one bubble is followed by a group of bubbles. The more and larger the bubbles, the bigger the carp. However, because carp have the habit of feeding in the mud, they also move in a mixed bubble, or a group of bubbles rises forward from time to time. Grass carp bubbles. One closed and broken bubbles. Generally, one or two larger bubbles appear first, and then some small bubbles appear one after another, and the bubbles burst when they come out of the water. 2. Watching fish by water ripples Observe the movement of fish underwater by water ripples: When the wind is calm, the water surface is as flat as a mirror, and you cannot see the movement of small fish, nor can you tell whether there are fish underwater; if the water is sparkling, ripples appear on the water surface from time to time, and fish splash water, chase and play, and sometimes jump out of the water, it means there are many fish underwater; small fish swimming and playing on the water surface are suddenly frightened and flee in all directions, or there are faint ripples on the water surface, which are mostly caused by the movement of big fish for food: if there are schools of fish floating on the water surface chewing water, it means that there is a lack of oxygen in the water and the fish will not forage. 3. Watching fish by water color As the saying goes: There are no big fish in clear water, and fish are easy to hide in muddy water. If the water is too clear, there are mostly no fish or few fish. The water is clear and shallow, and there is no duckweed or other concealment, so fish can easily see the shadows of people and fishing rods, and dare not come to take bait, so it is difficult to catch them. When fishing in ditches and rivers, the water color suitable for fishing is mostly light green, light blue or light cyan. If there are more water plants, the water color is relatively light. The most suitable water color for fishing in ponds is light white, light brown, light green or slightly muddy in the clear. Fourth, observe fish by water plants. See whether the water plants in the water are lush. If the water plants are lush, it means that there are few herbivorous fish. Look at the traces of water plants. If the water plants are incomplete and the grass stems are floating, it means that there are more herbivorous fish, and the size of herbivorous fish can be judged according to the depth of the water plants being eaten. If there is no grass, it means there are many fish. The vibration of the leaves of water plants indicates that there must be fish living in the grass, which is an ideal place for fishing. You can also observe the type of fish according to the degree and state of the shaking of water plants. If a single grass shakes lightly, it is mostly crucian carp, if a single grass bounces, it is mostly grass carp, and if a piece of grass shakes lightly, it is mostly carp. 5. Observe fish by smelling the water. Before fishing, stand facing the wind or squat on the shore and smell the wind blowing from the water surface to see if there is any fishy smell, or hold water in your hands and smell it to see if there is any fishy smell. The stronger the fishy smell, the more foam formed by the mucus secretions left by the fish school, and the more fish there are. On the contrary, there are fewer fish. 6. Listen to the sound of water. People with some fishing experience know that you can judge the fish situation based on the sound of water splashing accompanied by fish jumping. Listen to the "crunching" sound of fish eating grass and the "thumping" sound of big fish chasing small fish. If there is sound, there are fish, and if there is no sound, there are few fish or no fish.

Question 3: The small fish in Qingshui River are called Tuyu by the locals. What is their scientific name? As shown in the picture, it should be

Cyprinidae Rhynchocypris or

i. Fish of the genus Phoxinus (difficult to identify)

The picture below shows Jiao's pointed i (gui) Rhynchocypris oxycephalus, also known as pointed i and pointed big kiss i

The body is long, slightly flattened, with a rounded abdomen and a slightly high caudal peduncle. The snout protrudes slightly in front of the upper lip or is flush with the upper lip, and the snout length is equal to or less than the distance between the eyes. The mouth is wide and shallow, arc-shaped. The scales are small and irregularly arranged. The lateral line is complete. It is commonly found in quiet waters of rivers with more aquatic plants.

It lives in rivers and lakes in East Asia. It can grow up to 17.2 cm in length. It is omnivorous, but mostly feeds on small fish and insects. It is distributed in the former Soviet Union, North Korea, Japan, and the Tumen River, Yellow River and Yangtze River systems in my country.

Question 4: What kind of fish are in the river? my country is one of the countries with the most freshwater surface in the world, with a freshwater area of ​​about 300 million mu, of which about 7,500 mu can be used for fish farming. Most of my country is located in the temperate or subtropical zone, with a mild climate and abundant rainfall, which is suitable for fish growth. There are also breeding technologies for excellent fish such as grass carp, silver carp, bighead carp, silver carp, tilapia, carp, crucian carp, and bream. Therefore, China is the country with the most developed freshwater aquaculture industry in the world today, and it ranks first in the world in terms of both breeding area and total output. Due to the vast territory of my country, the geographical and natural environment are different, and the fish species and pattern characteristics of each region are classified according to the regional climate. The distribution of fish is as follows: Southeast region: including Guangdong, Guangxi, Yunnan, Guizhou, Fujian, Taiwan and Hainan Island. These areas mainly grow warm-loving fish with a wide variety of species, including dace, croaker, Chinese mackerel, Dongpo fish, flower loach, wax loach, sand loach, flat-headed flat loach, rock climbing loach, flat-fin loach, small-nosed fish, long-fin catfish, bearded catfish, eel, yellow eel, fighting fish, climbing perch, etc. The main farmed fish are southern species such as silver carp, grass carp, bighead carp, dace, group-toed bream, bearded catfish, tilapia, etc. River plain area: This includes the middle and lower reaches of the Yangtze River, the lower reaches of the Yellow River and the lower reaches of the Liaohe River. In addition to the river basins, there are many lakes here. It is the main production area of ​​freshwater fish in my country. It is famous for its many natural aquatic fish, including silver carp, grass carp, bighead carp, carp, crucian carp, catfish, bream, group-headed bream, black carp, eel, etc. The output of silverfish in Taihu Lake and sturgeon, carp and anchovy in Yangtze River is very large. The fish species farmed include silver carp, grass carp, bighead carp, carp, crucian carp, bighead bream, tilapia and some carp hybrids. Northern area: cold water fish are mainly produced here. Natural water bodies are rich in fish of the genera Acipenser, Pike and Taimen. For example, salmon, pike, sweetfish, snowfish, red snapper and lamprey are the unique and representative fish here. In addition to silver carp, grass carp, bighead carp, carp, crucian carp and bighead bream, red trout is also raised in artificial breeding. Northwest plateau area: including Xinjiang, northern Taiwan, Inner Mongolia, Qinghai, Gansu, Shaanxi, Shanxi and other places. This is a typical continental climate. Natural water bodies are rich in Chinese bowfish, yellow claw fish, naked carp and other fish, as well as loach and river loach. The main breeding is still the same as in other places. Nulan District: It includes southern Taiwan, Sichuan, and western Yunnan. Nujiang, Lancangjiang, Jinshajiang, and Yarlung Zangbo rivers all flow through here, so fish from the southeastern and northwestern plateau regions coexist here through the rivers, such as dace, Chinese mackerel, Dongpo fish, flat-fin loach, sand loach, striped loach, barracuda, perch, yellow mullet, black snakehead, and Chinese bowfish, forming a mixed fish community in the southeastern and northwestern regions. The main breeding is still green carp, grass carp, silver carp, bighead carp, carp, crucian carp, bighead bream, and carp hybrids that have been bred in large quantities in recent years.

Question 5: What are the small fish in the river that don't grow big called? The kind that can be eaten is usually eaten by cats. You can eat it if you want.

Question 6: What is the name of the beautiful little fish in the river? Round-tailed Betta

The round-tailed fighting fish (scientific name: Magongropodus ocellatus) is a fish of the family Bettaidae. It is distributed in China (from the north of the Pearl River to the Heilongjiang River), Japan (central and southern parts, but it may be an introduced species), South Korea and Russia (Heilongjiang River, but it may be an introduced species), and generally lives in the tributaries of rivers.

Question 7: What is the name of this small fish? The questioner caught it in the north of the river, right? This is commonly known as Baitiao, the same as Zhang Shun's Baitiao in Langli. Its scientific name is Bai Xiao.

Question 8: What is the name of this small fish in the northern rivers? It would be best if it is the scientific name.

Question 9: What kind of fish is this small fish caught in the river? As shown in the picture, it should be

Osphronemidae Macropodus fish

The picture below shows the round-tailed fighting fish Macropodus ocellatus, commonly known as the money betta

The round-tailed betta is mainly carnivorous. In its natural environment, it mainly feeds on rice field pests and mosquito larvae. It is a beneficial fish.
