Distribution and abundance of larval sablefish (Anoplopoma fimbria) in the surface waters off the west coast of Vancouver Island, April 9-24, 1985 / by W. Shaw, G.A. McFarlane, and D. Davenport.: Fs97-4/1945E-PDF

"The surface distribution and abundance of larval sablefish was examined using a neuston net off Vancouver Island from April 9 to 24, 1985. A total of 61 stations was fished at night of which 17 were repeated during daylight hours. Sablefish larvae were caught at 46 stations for a total of 823 larvae. They composed 10.9% of the total catch of larvae and occurred at 68.9% of the stations sampled at night. Their relative abundance increased at stations seaward of the 200 m isobath. Relative abundance estimates from night tows ranged from 0 to 262.9 larvae per 1000 m³ and from 0 to 15.1 larvae per 1000 m³ for day tows. Sablefish larvae were most abundant off Barkley Sound, averaging 38.4 larvae per 1000 m³ per station. Sablefish larvae ranged in length from 6 to 34 mm and averaged 14.9 mm (SE=0.69). Ninety-five percent ranged in length from 9 to 20 mm. Other larval species caught during this survey are also discussed in this report"--Abstract, page iii.
