Broad Whitefish

 

(Coregonus nasus), a lake and river fish with a body length reaching 80 cm and a weight of 2–4 kg (sometimes to 16 kg). The broad whitefish is common in the basin of the Arctic Ocean from the Pechora to the Anadyr’. It is sometimes found in the salt waters of gulfs and bays. The fish reaches sexual maturity at six or seven years of age. Spawning occurs in October and November. The female deposits 13,000 to 135,000 large eggs that reach 4 mm in diameter. The broad whitefish feeds mainly on benthic invertebrates. It winters in river channels. The fish is commercially valuable.

Species-specific restrictions are not possible because humpback whitefish and least cisco, as well as round whitefish (Prosopium tylindraceum) and the occasional broad whitefish (Coregonus nasus), often occupy the same areas in the river concurrently, and it is difficult to distinguish among species while spear fishing.
