CATDOLL : CATDOLL: The difference between yellow croaker and large yellow croaker

1. The difference between yellow croaker and large yellow croaker

Large yellow croaker and small yellow croaker are two different species.

Generally speaking, the size of large yellow croaker is larger than that of small yellow croaker, but this is not a fixed feature and cannot be used as the main basis for judging the size of "yellow croaker". Comparing the shapes of these two fish, it is not difficult to find obvious differences between them.

First, the length of the caudal peduncle of the large yellow croaker (i.e. the vertical distance between the end point of the anal fin base and the base of the caudal fin) is more than three times its height, while the caudal peduncle of the small yellow croaker is only more than twice its height. Don't underestimate this "double" difference, because with this difference, the large yellow croaker's tail is thinner and longer, and can be distinguished from the small yellow croaker.

Secondly, above the lateral line, the large yellow croaker has 8-9 rows of scales, while the small yellow croaker has only 5-6 rows. In comparison, the large yellow croaker has smaller scales, while the small yellow croaker has larger scales. Of course, this is just a comparison between the two.

1. Yellow croaker includes small yellow croaker and large yellow croaker, and large yellow croaker is a type of yellow croaker. 2. Compared with yellow croaker, which is not large yellow croaker, that is, small yellow croaker, large yellow croaker has a larger head and eyes. 3. Because large yellow croaker prefers warm water, its distribution range in my country is also further south than that of small yellow croaker. Both large yellow croaker and small yellow croaker are marine fish and are edible fish.

Types of fish

1. Bighead carp has a very strong adaptability and is widely distributed in the east, west, south and north of my country. No matter in the warm south or the cold north, rivers, lakes and reservoirs are all areas where they are active. They like warm water and filter-feed plankton and plants. They are filter-feeding fish and are one of my country's economic fish species. They are also a delicacy on the public table.

2. Black carp can be found in all major water systems in my country. It is widely distributed and likes to move underwater to find food. It likes to eat shellfish, insects, mollusks, and grains. It likes warm and cold water bodies and is mostly found in the vast plains and rivers south of the Yangtze River. Now many lakes and reservoirs have begun to breed them in large quantities.

3. Channa, also known as black fish, is widely distributed. It likes to hide at the bottom of the water. It is ferocious by nature and will attack the intruders at any opportunity. It is carnivorous. Fujian, Yunnan, Jiangxi, Guangdong, Zhejiang, Taiwan, Southeast Asia and other places are its habitats. It has more than a dozen species. Fighting this fish is very exciting.

4. Tilapia, also known as African crucian carp, is an introduced species with strong fertility and adaptability. It is distributed in all major water bodies in the south. It likes warm water and can be found in all water layers. It is an omnivorous fish and can be caught in rivers, lakes, reservoirs, streams and ponds.

5. Fish, living in the waters of central and southern Taiwan. Likes to live in the middle and lower layers of the water, moves in the middle and upper layers of the water when looking for food, and likes warm water. It is a carnivorous fish with an extremely ferocious temperament. It is known as the worst of all fish and has the title of the overlord of the water.

2. The difference between wild yellow croaker and farmed yellow croaker

The differences between wild yellow croaker and farmed yellow croaker include: different fish heads, different tail lengths, different dorsal fin scales, different tastes, and different fish lips.

1. Fish heads are different:

The head of wild yellow croaker is relatively pointed, while the head of farmed yellow croaker is relatively large and rounded.

2. Different lengths of fish tails:

Wild yellow croaker lives in the sea for a long time, so their tails are relatively long; while farmed yellow croaker lives in narrow environments such as cages all year round, and due to limited living space, their tails are relatively short.

3. Dorsal fin scales are different:

The dorsal fin of wild yellow croaker is serrated, long and pointed, and slightly yellow or transparent in color, and the scales are not inverted; while the dorsal fin of farmed yellow croaker is rough, grayish white in color, and has inverted scales.

4. Different taste:

Wild yellow croaker feels very sticky when eaten, while farmed yellow croaker has very poor stickiness and tends to loosen when stewed.

5. Fish lips are different:

The lips of wild yellow croaker are yellow and have abundant and firm plaque, while the lips of farmed yellow croaker are lighter in color and the plaque falls off easily.

Yellow croaker science:

Large yellow croaker is distributed in the southern Yellow Sea, the East China Sea and the South China Sea, while small yellow croaker is distributed in the Yellow Sea, Bohai Sea, East China Sea and the west coast of North Korea. Distribution map: They hibernate in the deep sea in winter and migrate to the coast in spring. After spawning from March to June, they disperse in the coastal waters to feed, mainly mysid shrimp, hair shrimp and small fish, and return to the deep sea in late autumn.

The small yellow croaker has a planktonic, benthic and swimming animal feed habit and has little selectivity for food. It mainly feeds on zooplankton, fish and shrimp, among which the zooplankton is mainly copepods, the fish are mainly goby, and the shrimps include hair shrimp, mysid shrimp, white shrimp and drum shrimp.

3. The difference between large yellow croaker and yellow croaker

The differences between these two fish are as follows:

1. Different size: The big yellow croaker is relatively large and has two hard stones on its head, while the stones on the top of the yellow croaker's head are smaller than those of the big yellow croaker.

2. Different appearance: The scales of big yellow croaker are golden yellow, and its body is slender and long, with high edible value, while yellow croaker is relatively small and slightly arched.

3. The living environment is different: Large yellow croaker mainly lives in the ocean and is a marine fish, while most yellow croakers are farmed and are freshwater fish.
