Black herring can be divided into wild fish and cultured fish. This kind of fish is not small. The more wild, the more valuable. The longer, the more valuable. It is rare for wild herring to reach 80 kg now, not to mention that there are not many people who breed herring artificially. Even if it is artificially cultivated, the specification is about 10 kg at most. The growth cycle of herring is very long, and it takes about three years to grow to tens of kilograms, which is also the reason why many farmers are unwilling to breed herring. The growth cycle is too long, the investment is too big, and you can't make any money. It is really difficult for herring to grow to 80 kilograms. Selling 5 thousand is really nothing.
Generally, the market price of herring under 20 kg is only 12 yuan per kg. Herring exceeding 20 kg is not priced by kg. Generally 30-50 kg of herring, the recycling price of fishmongers is about 3000-5000 yuan. Eighty kilograms of herring can be said to be very rare, and the price recovered by fishmongers is about 8000 to 1000. Of course, depending on the situation, the price may be different, but it won't be much different.
Black herring is one of the four traditional freshwater fish in China, because it belongs to the lower class and its food is mainly snails. The life span of herring is very long, generally reaching 20-30 years. Black herring is naturally inactive, and rarely moves underwater except for preying, which is equivalent to being in the water? Sloth? . Coupled with long life and inactivity, herring is also relatively large. Generally, 30 kg of herring over 5 years old, 150-60 kg of herring over 0 years old, and 80 kg of herring takes about15 years, so things are rare.
Unlike other toothless fish, herring has teeth. Its teeth are located in the pharynx of the mouth, shaped like human teeth, and have a strong bite force. When herring swallows snails and mussels into their mouths, they bite crustaceans with their teeth and eat only the meat inside crustaceans. The more herring eat, the bigger the cartilage will be. Is this what we call cartilage? Herring stone? Herring stone is also very valuable. To sum up, it is not cost-effective to sell 80 kg of herring for 5000 yuan.
