Abstract--Three yellowfin tuna (Thunnus albacares) carrying ultrasonic depth-sensitive transmitters developed a strong association with the tracking vessel, following it at speeds up to 5 knots (2.6 m/s). Two fish associated with the tracking vessel during daytime, and the other fish ...
Identification of rockfish (Sebastes spp.) by restriction site analysis of the mitochondrial ND-3/ND-4 and 12S/16S rRNA gene regions.(Statistical Data Included)
Jan 01, 2001; ... Abstract--Species-specific restriction site variation in the 12S/16S rRNA and ND-3/ND-4 mtDNA regions was used to distinguish among 15 rockfish species of the genus Sebastes common to the waters of Alaska. Intraspecific variation exhibited by eight of the species (based on five individuals ...
A comparison of the precision and accuracy of estimates of reef-fish lengths determined visually by divers with estimates produced by a stereo-video system.(Statistical Data Included)
Jan 01, 2001; ... Abstract--Visual estimates of reef-fish length are a nondestructive and useful way of determining the biomass, mean length, or length frequency of reef fish. Consequently, visual estimates of reef-fish length are often an important component of reef-fish monitoring programs, many of which ...
Improving the statistical power of length estimates of reef fish: a comparison of estimates determined visually by divers with estimates produced by a stereo-video system.(Statistical Data Included)
Jan 01, 2001; ... Abstract--We calculated the power of visual length estimates by novice and experienced scientific SCUBA divers and estimates generated by a stereo-video system to detect changes in the mean length of three common species of reef fish from New Zealand. Length estimates from a stereo-video ...
Dynamics of larval fish abundance in Penobscot Bay, Maine.(Statistical Data Included)
Jan 01, 2001; ... Abstract--Biweekly ichthyoplankton surveys were conducted in Penobscot Bay, Maine, during the spring and early summer of 1997 and 1998. Larvae from demersal eggs dominated the catch from late winter through spring, but not in early summer collections. Larval fish assemblages varied with ...
Population structure of Fraser River chinook salmon (Oncorhynchus tshawytscha): an analysis using microsatellite DNA markers.(Statistical Data Included)
Jan 01, 2001; ... Abstract--Microsatellite DNA analysis was applied in a genetic study of 20 chinook salmon populations from four regions within the Fraser River drainage of British Columbia, Canada. Twelve populations were represented by samples collected in different years. A total of 2612 fish were ...
Annual and batch fecundities of yellowfin sole, Limanda aspera, in the eastern Bering Sea.(Statistical Data Included)
Jan 01, 2001; ... Abstract--Annual and batch fecundities of yellowfin sole, Limanda aspera, in the eastern Bering Sea were determined. Most individuals had a determinate, group-synchronous mode of oocyte development as evidenced by a distinctly separate distribution of fully yolked oocytes in more advanced ...
Analysis of contemporary genetic structure of even-broodyear populations of Asian and western Alaskan pink salmon, Oncorhynchus gorbuscha.(Statistical Data Included)
Jan 01, 2001; ... Abstract--Even-year pink salmon (Oncorhynchus gorbuscha) populations from the Russian Far East and Japan exhibit genetic structure that reflects their geographic relationships. Extension of genetic analysis to include data from Bering Sea and northern Gulf of Alaska populations shows a ...
Validation of age estimation and back-calculation of fish length based on otolith microstructures in tilapias (Pisces, Cichlidae).(Statistical Data Included)
Jan 01, 2001; ... Abstract--Two tilapia species, Sarotherodon melanotheron (brackishwater fish) and Oreochromis niloticus (freshwater fish), were marked with tetracycline and reared in Cote d'Ivoire (West Africa) in intensive (fish fed) and extensive (fish unfed) conditions. Juvenile and adult otoliths of ...
Bayesian methods for analysis of stock mixtures from genetic characters.(Statistical Data Included)
Jan 01, 2001; ... Abstract--An implementation of Bayesian methods to assess general stock mixtures is described. An informative prior for genetic characters of the separate stocks in a mixture is derived from baseline samples. A neutral, low-information prior is used for the stock proportions in the ...
The potential role of marine reserves in the management of shortraker rockfish (Sebastes borealis) and rougheye rockfish (S. aleutianus) in the Gulf of Alaska.
Jan 01, 2001; ... Abstract--Shortraker and rougheye rockfish (Sebastes borealis and S. aleutianus) have been an independent management subgroup of the Gulf of Alaska slope rockfish assemblage since 1991. Special concerns are proposed for the management of these species because they are very slow growing, ...
The diet of the large coral reef serranid Plectropomus leopordus in two fishing zones on the Great Barrier Reef, Australia.(Statistical Data Included)
Jan 01, 2001; ... Abstract--The diet of Plectropomus leopardus (Serranidae, Lacepede 1802) was examined on two pairs of reefs in the Cairns Section of the Great Barrier Reef Marine Park, Australia. For both pairs, one reef was open to fishing and the other had been closed to fishing for eight years; however ...
Estimating tag-shedding rates for skipjack tuna, Katsuwonus pelamis, off the Maldives.(Statistical Data Included)
Jan 01, 2001; ... One source of uncertainty in fishery assessments based on tag release and recapture data arises from tag shedding--the loss of tags from fish from the time of tagging until tag recovery. Independent estimation of tag-shedding rates from double tagging experiments is an integral part of ...
The effect of sea state on estimates of abundance for beluga whales (Delphinapterus leucas) in Norton Sound, Alaska.(Statistical Data Included)

Beluga whales (Delphinapterus leucas) are relatively small odontocete cetaceans; standard lengths of newborn calves are about 160 cm and adults range from 300 to 450 cm (Doidge, 1990). At birth, calves are dark slate gray, and the color gradually lightens until they become pure white as ...
