The Blackfin Seabass is a species of Asian seabass. It is highly regarded as both a food fish and a gamefish. Large fish are often caught in the area of shallow rocks and reefs and, in southern Japan even in the brackish waters of river mouths. They grow to 40 inches and up to 23 pounds.
The Blackfin Seabass is similar in shape to the striped bass of the US waters. It has an elongate, compressed, silvery body, a large mouth of which the lower jaw projects beyond the upper jaw, and a slightly forked tail. It lacks the stripes of the striped bass. The Blackfin Seabass differs from the Japanese Seabass in having a deeper body, a row of scales on the lower jaw, and a more silvery body color. In addition, the meristic counts of dorsal and anal fin elements differ. The Blackfin Seabass has 12 dorsal fin spines with 15 16 soft rays and 3 anal fin spines with 9 10 soft rays. The Japanese Seabass has 12 15 dorsal fin spines with 12 14 soft rays and 3 anal fin spines with 7 9 soft rays. The lateral line pore count is 71 76 for the Blackfin Seabass.
The Blackfin Seabass can be taken by surfcasting with flashy, minnow-shaped artificial lures or metal jigs, or by fly fishing with feather streamers as well as by bait fishing with small live baits and by fly fishing with streamers. In the southern waters of Japan, the Blackfin Seabass is caught more often than its close relative, the Japanese Seabass.
The Blackfin Seabass is native to the north eastern Pacific from the Shizuoka and Chiba Prefectures, in central Japan southward to the Nagasaki Prefecture and the East China Sea.
