This dataset contains 2-boat tow, push net and scoop net catches from the Yukon River Delta for 2014

Data sets used to support analysis published by O'Corry-Crowe et al (2014) Crossing to safety: Dispersal, colonization and mate choice in evolutionarily distinct populations of Steller sea lions, Eumetopias jubatus. Molecular Ecology 23(22): 5415-5434. Data include Steller sea lion genetic data obtained from samples collected from pups on natal rookeries. The genetic data are genotypes at 16 microsatellite loci and haplotypes at mtDNA, spatial data, and allelic and haplotypic frequencies.

Information on the distribution and relative abundance of nearshore fishes from beach seine hauls in Alaska is now available to managers as an online Fish Atlas. The atlas is dynamic and will continually be updated as more data becomes available. Presently, the atlas includes distribution and habitat use information for nearshore fishes in southeastern Alaska, Prince William Sound, the Aleutian Islands, and the Arctic. This online database has been designed to integrate with the spatially explicit, Alaska ShoreZone web enabled GIS platform. Further details about the database design can be found on Auke Bay Laboratories public website.

This dataset is from a study examining the growth responses of juvenile walleye pollock at ambient and 3 elevated CO2 levels.

These are the data from a laboratory experiment in which DNA content was removed from blood smears and extracted. The blood smears were either stained with Giemsa-stain or remained un-stained. Some of the un-stained smears were coverslipped. Host and parasitic DNA was amplified using conventional PCR.

An experimental bottom longline survey was conducted at depths >1,000 m in the western Gulf of Alaska in August 2008. The objective was to investigate the abundance and biological characteristics of giant grenadier (Albatrossia pectoralis) and sablefish (Anoplopoma fimbria) in deep waters of the Gulf of Alaska that have not been previously sampled in fishery surveys. Several difficulties were encountered during the fishing operations which indicate special problems may occur when fishing longlines at these depths, including substantial gear drift after setting and hang-ups on the bottom that caused the longline to part. Although results were not conclusive because only stations in the western Gulf of Alaska were sampled, there was consistency in the results which provides an indication of fish abundance and distribution in depths >1,000 m. Catch rates of giant grenadier were relatively high, although not as large as those in nearby longline survey stations in depths 1,000 m. Besides giant grenadier, Pacific grenadier (Coryphaenoides acrolepis) was the only other species caught in substantial numbers. At one deep-water station, Pacific grenadier were extremely abundant and were caught on 56% of the longlines hooks.

Stock assessment of Alaskan red king crab, Paralithodes camtschaticus (Tilesius, 1815), can be improved by incorporating reproductive output, which requires an understanding of the size-fecundity relationship, interannual and seasonal variability in fecundity, and maternal size effects on embryo and larval quality. We collected red king crab egg clutches from Bristol Bay, Alaska, in summer of 2007-2010 and autumn of 2007-2009 and estimated fecundity. A monitoring project examining the size-fecundity relationship began in 2012 and data is collected every other year.In June 2009 and 2010 we collected embryo clutches of recently extruded red king crab embryos in Bristol Bay, Alaska, to assess embryo quality based on dry weight, carbon and nitrogen content. To assess larval quality, we collected ovigerous females from Bristol Bay in 2007 and reared them in the laboratory until larval hatching in 2008. Larval quality based on dry weight, carbon and nitrogen content, and time to 50% mortality under starvation conditions was assessed.

This data is from an experiment designed to test the viability of using hatchery reared crab to supplement wild stocks and to determine the optimal density for future releases. Crab were released by divers into 5 x 5 m quadrats marked with ground line at three densities: 25, 50, and 75 m-2. Researchers monitored the crab density inside the plots, in order to estimate survival, as well as outside the plots, to estimate crab movement. In addition, they determined predator densities and performed tethering experiments on red king crab to see if predator density or predation risk differed among the density treatments.

This dataset is part of a laboratory experiment, which evaluated how varying ratios of prey species (year-0 blue and red king crabs) and habitat type (shell and cobble) affect prey preference of year-1 red king crabs. The data includes experimental duration, tank number, predator species, prey species, substrate type, initial and final prey densities, number of prey eaten, crypsis indices, and survival.

The data from this study, describes embryo development in Golden king crab, Lithodes aequispinus. Six female multiparous golden king crab were captured from the Aleutian Islands, Alaska, and mated in the laboratory. Their embryos were photographed and staged on average once every 9 days throughout embryogenesis.
