Maturation, spawning and growth of rock soles off Kodiak Island in the Gulf of Alaska
Northern rock sole Lepidopsetta polyxystra females from the Kodiak Island area, Alaska, reached 50% maturity at 328 mm L T and an average age of 7 years. In contrast, southern rock sole Lepidopsetta bilineata females reached 50% maturity at 347 mm L T and an average age of 9 years. Spawning started...
