is distinguished from the remaining species of the genus Leporinus by its color pattern of: one longitudinal and discontinuous narrow dark brown stripe running inconspicuously from a vertical through middle of dorsal fin to base of caudal peduncle along lateral line; two or three large dark brown vertically elongated blotches along middle trunk: first at the vertical through dorsal-fin, second anterior to adipose fin and third on the caudal peduncle; mainly in young specimens, 12-13 short transversal dark brown bars meeting small dark brown blotches laterally.

Catfishes of the highly specialized bagrid genus Bagrichthys Bleeker, 1858, live in large muddy fivers throughout Southeast Asia and are characterised by their elongate and laterally compressed caudal peduncle, the dorsally-directed serrations on the posterior edge of the dorsal-fin spine, gill membranes united at the isthmus, and a long adipose fin without a free posterior margin (Roberts 1989, Mo 1991).

Blackwater trout can be identified by the intact adipose fin, the small fin on the trout's back between the tail and the large dorsal fin.

The first segment, July 1-31, will be an "all salmon mark-selective coho fishery" in which anglers will be allowed to retain only coho with a clipped adipose fin. A maximum harvest of 10,500 silvers will be allowed between Cape Falcon and the Oregon-California border.

Salmon fishing won't be 'lights out'

Rainbow trout have a speckled back, and most but not all hatchery rainbow trout have had their adipose fin - the fin on their back, between their main, or dorsal fin, and the tail - clipped.

Anglers, of course, may target only hatchery-reared "springers," marked by a clipped adipose fin.

It's a selective coho season, which means a limit of two salmon per day that have a healed adipose fin clip.
