What is china rock fish?

China rock fish (Sebastes nebulosus) is a species of fish that belongs to the Scorpaenidae family. It is commonly found in the North Pacific Ocean along the coasts of Japan, Russia, and the United States, including Alaska, Washington, and Oregon.

These fish are bottom dwellers and inhabit rocky reef areas, usually at depths ranging from 10 to 100 meters. They are known to be slow-growing, with females reaching sexual maturity at the age of 6-7 years old and males at 3-4 years old.

China rock fish can grow up to 50 cm in length and weigh up to 2 kg. They are characterized by their reddish to brownish coloration, with irregular blotches and spots on their body. They have spiny dorsal fins and venomous spines on their pectoral and anal fins, which they use for protection against predators.

China rock fish are often caught for commercial and recreational fishing, and their flesh is considered to be of good quality and taste. However, overfishing and habitat destruction have resulted in a decline in their population, and they are now listed as a species of "least concern" on the IUCN Red List of Threatened Species.
