Blackbelly Rosefish - marine fish Blackbelly rosefish, also known as bluemouth rockfish or bluemouth seaperch, is a species of marine fish that belongs to the Sbastinae subfamily within the family Scorpaenidae. It is a robust fish that is characterized by its huge head without tentacles or tabs.
It has a large mouth with villiform teeth and large jaws, the inside of its mouth is dark-colored. Its dorsal fish has up to 13 spines with up to 14 rays. The anal fish is characterized by 3 spiky spines and 5 rays. Its pectoral fin has up to 20 rays. Its chest and cheek as well as maxilla are usually scaled while the head and ventral part are naked. It can vary in color. Its back and sides are dark to bright red and the belly is most often pink. The scales have up to 6 dark bands. Its spines contain venomous toxins that may be harmful to humans. There are not many researchers on the venom produced by this species.
Blackbelly rosefish is a scorpionfish that is usually found in the bottom areas of the continental shelf. They commonly appear at depths from 150 to 600 m. Their diet is composed of other fishes, crustaceans, as well as polychaetes, echinoderms, or pyrosomes. The prey is strongly dependent on the size of the fish.
The fish commonly measures up to 25 centimeters in length, but the largest caught representative measured 47 cm in total length. Males reach much greater sizes and weight than females. Blackbelly rosefish can live up to 45 years. There are four main places where the fish occurs naturally: in the northeast Atlantic (Norway, North Africa, and the Mediterranean), northwest Atlantic (Nova Scotia and Venezuela), in South Africa, and in the Gulf of Guinea.
It is the most commercial scorpionfish in the Mediterranean. It is most often caught as bycatch by fisheries that specialize in deep-sea crustaceans fishing. It is also often caught along the Portuguese continental coast and the Azores. In some areas such as the Catalan coast, the fish has a great economic value, partially due to its low level of accessibility.
Global blackbelly rosefish production
According to the Food and Agriculture Organization of the United Nations (FAO), blackbelly rosefish accounted for approximately 2,460 tonnes of global fish production in 2016. This made it the eleventh most commonly produced fish species in the world that year. The majority of blackbelly rosefish production takes place in Asia, with China being the single largest producer. In 2016, Chinese blackbelly rosefish production amounted to 1,378 tonnes, over 56 percent of the global total. Other significant producers of blackbelly rosefish include India, Japan, and Vietnam.
In addition to being an important food fish, blackbelly rosefish is also used in traditional Chinese medicine. The species is sometimes referred to as "ginseng fish" because of its purported health benefits. Blackbelly rosefish is said to improve circulation, boost energy levels, and promote overall good health.
Despite its popularity, blackbelly rosefish is considered to be a threatened species. Overfishing and habitat loss are the main threats to the species' survival. In order to protect blackbelly rosefish, various conservation measures have been put in place, including catch limits and bans on fishing in certain areas.
