Acanthopagrus berda, the goldsilk seabream, sly bream, picnic seabream, black sea bream, black porgy, picky bream, silver bream or river bream, is a species of ray-finned fish belonging to the family Sparidae, the sea breams and porgies. This species is found in the Indian Ocean.

Taxonomy Acanthopargus berda was first formally described as Sparus berda in 1775 by the Danish zoologist Johan Christian Fabricius and published in Descriptiones animalium edited by Carsten Niebuhr. Fabricius based his description on the notes of Peter Forsskål who had died while on an expedition, which Neibuhr was also a member of, to Arabia. The Type locality was given as Al Luhayyah in Yemen. Some authorities classify the genus Acanthopagrus in the subfamily Sparinae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.

Etymology Acanthopagrus berda has the specific name berda, which is the name for this species along the Red Sea coast of Yemen.

Description Acanthopagrus berda has a relatively deep and compressed body with the depth of its body fitting into its standard length between 2.4 and 2.6 times. The dorsal fin is supported by 11 or 12 spines, while the anal fin has 3 spines, with the second spine being longer than the third, and 8 or 9 soft rays. There are robust molar-like teeth along both jaws, the rows of these teeth are clearly curved laterally at the back of the lower jaw.
