What Are Mullet and Mullet Roe? Taiwan's Mullet Roe Rises to a National Competition
Do you know the mullet? The mullet, also known as the grey mullet, is a migratory fish. In the ten days before and after the winter solstice, when cold fronts arrive, mullet appear in large numbers near the Taiwan Strait to migrate and spawn. For hundreds of years this has never failed or paused, so it is called the "faithful fish." During the Xia and Shang dynasties

Detailed Explanation of Key Points in Mullet Fry and Fingerling Production Technology
The fry and fingerling production of mullet and Liza mullet includes two major steps: artificial propagation and fry and fingerling rearing. The former is further divided into broodstock rearing, induced spawning (artificial induction of ovulation), artificial insemination, and artificial incubation; the latter is further divided into fry rearing and fingerling rearing. Research on artificial propagation of mullet dates back to 1930, when Italy completed the first artificial spawning of mullet. It was not until the past one to two decades that it attracted widespread attention from relevant countries around the world and became an important subject of international biological research. China, the United States, India, the former

What are the prevention and treatment methods for mullet diseases?
Mullet belongs to the order Mugiliformes, genus Liza, and its external morphology is similar to that of the grey mullet, but its adipose eyelid is not well developed. It lives in coastal waters and estuaries and can also live in freshwater, being a eurythermal and euryhaline fish. Under natural conditions, it scrapes and feeds on diatoms and decaying organic matter, and also eats benthic organisms. In pond aquaculture, artificial compound feed can be used. Among cultured species, there is a saying of "grey mullet in the south, mullet in the north." In Jiangsu and areas to the north, mullet farming is mainly practiced. In recent years, the momentum of using freshwater ponds to culture mullet in coastal areas has developed rapidly, shifting from polyculture to

Detailed Explanation of Key Points for Artificial Breeding of Mullet
Selection and cultivation of broodstock: In autumn or early winter, select intact and uninjured individuals from those caught in sea areas or from adult fish raised in seawater or brackish water as broodstock. Female fish should be 3 years old and weigh more than 1.5 kg; male fish should be 2 years old and weigh more than 1 kg. The broodstock pond area should not be too large, preferably 1500-2000 sq m, with a water depth of 1.5-2 m, access to seawater and freshwater sources, and convenient drainage and irrigation. The stocking density per mu of broodstock pond should not exceed 100 kg. Mullet begin to seek food in small amounts at a water temperature of 4°C,

Detailed Explanation of Key Technical Points for Artificial Ovulation Induction in Mullet
(1) Basic Principles Artificial ovulation induction is also called induced spawning. Commonly known as spawning induction, etc. It refers to the use of artificial methods to inject drugs into broodstock fish whose gonads have developed to maturity, stimulating the gonads to further mature and release, thereby obtaining mature eggs (or male fish sperm). Accurately grasping the spawning induction season, selecting broodstock suitable for induced spawning, injecting effective doses within the appropriate temperature range - these are the necessary conditions for artificial induced spawning. Whether the spawning induction technique is appropriate or not affects the fertilization rate of fish eggs, the hatching rate, as well as the spawning success rate and post-spawning

Mullet
Mullet, also known as rougunzi (Liaoning, Hebei), red-eye fish (Shandong), red-eyed mullet, red-eye grey mullet (Zhejiang, Fujian), zhaiyu (Guangdong). (1) Morphological characteristics: The snout is short; the front part of the body is subcylindrical, and the rear part is laterally compressed. The eyes are relatively small, the adipose eyelid is not well developed, and there is a red ring around the eye. The maxilla bends abruptly downward at the corner of the mouth. The origin of the first dorsal fin is closer to the tip of the snout than to the base of the tail. The posterior margin of the caudal fin is slightly concave. The body is bluish grey, the belly is white, and there are black longitudinal stripes on the sides of the body. All fins are light grey. (2

How to seize the golden time for mullet polyculture?
Aquaculture farmers in Chaoshan, Shenzhen, Dongguan and other areas of our province who let the four major Chinese carps and tilapia be polycultured with mullet in freshwater ponds mostly achieve relatively good economic returns. Polyculturing mullet in home fish ponds requires little investment and yields high profits, and is worth trying for farmers who raise the four major Chinese carps and tilapia. Mullet (scientific name Mugil cephalus), mainly produced along the southeastern coast of China, has wide adaptability: it can live in seawater and, through desalination, can also be farmed in a completely freshwater environment. Its fry, after being caught by hand and desalinated,
