- 23 October 2006
The assemblages of the demersal fish fauna of the Azores Archipelago are described from longline surveys that extended from the coastline to 1200 m water depth. A total of 104 fish spe- cies from 47…

The Pacific sleeper sharks appear to employ a stealth and ambush hunting strategy that incorporates slow vertical oscillations to search for prey, and cryptic colouration and cover of darkness to avoid detection by potential prey.
Young of the Year Sablefish Abundance, Growth, and Diet in the Gulf of Alaska

Abundance is dependent on year class success, which is highly variable from year to year. We studied young of the year sablefish AnoplopomaJimbria to collect basic life history information on their…
Sperm whale depredation of sablefish longline gear in the northeast Pacific Ocean

- Environmental Science
- 2008
The magnitude of sperm whale depredation on a major North Pacific longline fishery (sablefish) using data collected during annual longline surveys was estimated to be < 1% of the annual sablefish long line fishery catch off Alaska during 1998 to 2004.
Abundance estimation and capture of sablefish (Anoplopoma fimbria) by longline gear
- M. Sigler

- 1 June 2000
Longline surveys in Alaska measure sablefish (Anoplopoma fimbria) relative abundance and are the primary information source used for abundance and quota estimation. Hook timer, on-bottom (soak) time,…
Effects of individual quotas on catching efficiency and spawning potential in the Alaska sablefish fishery
- M. Sigler, C. Lunsford
- Environmental Science
- 1 July 2001
It is found that IFQ management increased fishery catch rate and decreased harvest of immature fish, and improved catching efficiency of the IFQ fishery reduced variable costs to catch the quota, averaging $3.1 million US annually.
Seasonal availability of abundant, energy-rich prey influences the abundance and diet of a marine predator, the Steller sea lion Eumetopias jubatus
Seasonal occupa- tion of Benjamin Island by sea lions is influenced by seasonally available, densely aggregated, energy-rich prey.
