The blackthroat seaperch (Doederleinia berycoides), also known as the rosy seabass, is a species of ray-finned fish in the family Acropomatidae, the temperate ocean-basses or lanternbellies.

The generic name honours the German zoologist Ludwig Heinrich Philipp Döderlein (1855-1936).

It lacks the luminous organ present in many other members of the lanternbelly family.

This high value has inspired biological and ecological studies that may be useful in the management of its fishery.

[4] It has been artificially bred in Japan and Taiwan with efforts being made both towards aquaculture and releasing fry/juvenile fish into the wild.
