Reference work entry
Far Eastern Navaga, or Pacific Navaga, Saffron Cod (Eleginus gracilis) – cold-loving benthic fish of the cod family (Gadidae). Common in the coastal waters of the Chukchi and Bering Seas, the Sea of Okhotsk, and the Sea of Japan. N migrates in the mouths of the rivers and lakes. The body length ranges from 15 to 50 cm; the usual length is 25–35 cm; the average age is 3–4.5 years. Its weight is 1.1 kg. It always keeps in the coastal zone, moving to the coast in winter for spawning and leaving the coastal zone in summer for fattening when the water is warmed up off the coast to a depth of 30–60 m. It spawns from December to February near the coast in the area of influence of tidal currents at a low, near-bottom temperature. Females lay 25,000–210,000 eggs. The period of egg development lasts from 80 to 90 days at temperatures up to −1.8 °C and salinity of 23–32 %. N feeds on crustaceans and fish fry. N becomes sexually mature at the age of 2–3 years. The greatest concentrations of N are recorded in the Anadyr-Navarin area and Bays of Olyutorsky, Korfa, and Karaginsky. N is a delicious important food fish, proteic, and low fat. Its ice fishing is widely used.
