Artificial breeding of the largescale blackfish succeeds, blackfish is no longer prohibitively expensive

As the weather gradually turns cooler, it is the season when gourmets prepare to feast on seafood, but fishermen who raise milkfish and hard clams have to worry about fish being frostbitten or dying suddenly because of the cold. Now the Fisheries Agency of the Council of Agriculture, through the "Blue Economy" program and in cooperation with academia, has successfully used cage net aquaculture to produce a high-value fish species commonly known as "black hair," the largescale blackfish (Girella punctata), which can serve as a working fish in hard clam ponds and can also be artificially cultured to increase fishermen's income.

"Black hair" is hard to come by, with a market price of more than 700 yuan per kg

The largescale blackfish is a native fish species of Taiwan, China, and its traces can be seen in the northwest Pacific Ocean, Japan, Hokkaido, the East China Sea, around Taiwan, China and its offshore islands, and other places. Although its flesh is delicious, because it is accustomed to spawning in the sea before returning to rocky shores to feed, it is not easy to collect its eggs for artificial breeding, so the largescale blackfish is rarely seen on the market, and only gourmets who know the ropes can enjoy its deliciousness.

Even if people happen to come across it by chance on market stalls or seafood restaurant menus, the price is mostly marked as "market price," and some seafood restaurants even quote a wholesale price of more than700yuan per kg, which is very expensive.

To this end, the Fisheries Agency of the Council of Agriculture cooperated with aquatic product experts and invested4years and more than4hundred million yuan in the "Taiwan Coastal Blue Economy Growth Promotion Program," and now it has been able to use "cage net aquaculture" to stably produce largescale blackfish, breaking the limitation of being able to catch them only through "rock fishing."

The largescale blackfish is cold-tolerant and heat-tolerant, with high economic value
