This book was released on 2004 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Chignik watershed, on the southern side of the Alaska Peninsula, supports a large salmon fishery vital to the local economy. Recent morphological changes to the watershed generated concern regarding the sockeye salmon (Oncorhynchus nerka) stock that rears in Black Lake, at the head of the system. Studies of the Chignik watershed to date have not incorporated energy density data to explain the life history strategies of Chignik sockeye salmon. Re-estimated condition factor parameters improved our understanding of the length-weight relationships to fish health that isometric models described in Chignik sockeye salmon. Subsequent comparisons of age, length, weight, location, and temperature data to energy density indicated that Black Lake fish, which were all age 0 fish, were significantly affected by temperature and had energy densities greater than did fish from other areas of the watershed. Sockeye salmon captured in Chignik Lake, Chignik River, and Chignik Lagoon were only energetically different from one another based on age. Observed seasonal trends suggested juvenile sockeye salmon emigrate from Black Lake before the onset of winter due to forage and temperature limitations. A constant downstream migration occurred in the watershed during the summer, which suggested smoltification and osmoregulation processes in Chignik Lagoon fish"--Leaf iii.

This book was released on 1987 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-day symposium was organized by the Department of Fisheries and Oceans and convened at Nanaimo, British Columbia in November 1985. Advice on subject matter and participation came from an external committee of senior scientists and administrators in contributing agencies in Canada, Japan, the United States, and the Union of Soviet Socialist Republics. The papers included in the proceedings deal with sockeye biology and stock management. Papers on sockeye biology are divided into those concerned primarily with life history strategies and enhancement and development. Papers dealing with management are divided into the tools of management and management of some principal stocks.

Book Synopsis Biology of Juvenile Sockeye Salmon Resident in Chignik River, Alaska by : Ronald Albert Iverson

This book was released on 1966 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life history of juvenile sockeye salmon (Oncorhynchus nerka) resident in Chignik River, Alaska, represents a departure from the lacustrine, pelagic existence typical of juveniles of this species. For this reason, the distribution, relative abundance in different parts of the river, growth, and upstream and downstream movements of juvenile sockeye in the river were studied during the summers of 1963 and 1964. The objectives of the study were to gain information on the possible origins of juvenile sockeye resident in Chignik River, and on the role of Chignik River in production of sockeye salmon. Distribution and abundance were estimated by seining and underwater observation. Juvenile sockeye appeared to be restricted to quiet waters along the shore. Catches of sockeye fry tended to increase through the summer, whereas catches of yearlings decreased. Smolts were taken in significant numbers only in June and July. early summer, large numbers of yearling sockeye were concentrated in Chignik River just below the outlet of Chignik Lake. In sockeye fry and yearlings captured in the lower river were generally larger than those captured in the upper river. Juvenile sockeye in the upper river grew slower than those in most other parts of the watershed. Scale analysis of sockeye salmon spawning in Chignik River showed that these fish entered the ocean at a larger size than did fish reared in Chignik Lake or Chignik River. This suggests that at least part of the progeny of river spawners do not remain in the river, but descend as fry to the brackish estuary, where growth conditions are superior. Upstream movement of schools of yearling sockeye was observed in the upper portions of the river. Such a movement has been observed many times in Chignik River in past years and has at times involved large numbers of fish. Schools of yearling sockeye have been observed to enter Chignik Lake. Fish of the same size group were captured while moving downstream at the lake outlet at night, suggesting a circular movement involving displacement of fish into the river at night and a positive rheotactic response causing them to re-enter the lake during the day. Juvenile sockeye salmon resident in Chignik River may include both progeny of river spawners, and fish which have moved down from Chignik Lake; Chignik Lake is probably the more important source. Chignik River is judged to have a minor role in the production of sockeye salmon, relative to the other rearing areas in the watershed.

This book was released on 2009 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The growth of Seward Peninsula sockeye salmon (Oncorhynchus nerka) from Salmon and Glacial lakes is related to their physical environment. Dermal scales collected over many years were measured to document the annual age specific growth of smolts and adults. The effect of fertilization on fry growth was examined using the first year of growth. The growth histories of Salmon Lake sockeye salmon were compared to Glacial Lake sockeye salmon through smolting and in the marine environment. Annual age specific fry growth had no direct relationship to fertilization; however, there were interactions between biomass of salmon prey and fertilization, and between prey biomass and age of smolting. Glacial Lake age-1 smolts are the same size as Salmon Lake age-1 smolts, but age-1.3 Salmon Lake juveniles after their first year in the ocean are smaller than age-1.3 Glacial Lake juveniles suggesting lower size based mortality. The differences in growth histories show each population's response to lake production and mortality experienced by smolt between the rearing lake and the ocean"--Leaf iii.

Hume and published by Cultus Lake, B.C. : Fisheries and Oceans Canada, Science. This book was released on 2000 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Juvenile sockeye salmon rearing in Babine Lake were re-examined 22 years after the initiation of the Babine Lake Development Project (BLDP). Abundance, distribution, size, and species composition of the limnetic fish populations, including juvenile sockeye salmon, were determined by hydroacoustic and midwater trawl surveys in the autumn of 1993 and the summer and fall of 1994 and 1995 and compared to results collected before and shortly after the start of the BDLP. Our objectives were to look for: 1) changes in the abundance of juvenile sockeye relative to spawning numbers; 2) changes in the utilization of the available nursery area; and 3) the effects of increased popualtion size and density on the size and growth of juvenile sockeye.

Available in PDF, EPUB and Kindle. Book excerpt: Much attention has been given to juvenile Sockeye Salmon (Oncorhynchus nerka) ecology with particular focus on pelagic food webs in deep nursery lakes. In contrast, this study took place at Afognak Lake, Alaska, to better understand juvenile Sockeye Salmon foraging ecology, potential consumer interactions, and metabolic opportunities and constraints in a shallow nursery lake. I collected fish every two weeks from Afognak Lake from May through August, 2013. I described ontogenetic and temporal variation in the diets of juvenile Sockeye Salmon and a potential competitor, adult Threespine Stickleback (Gasterosteus aculeatus). Notably, this study revealed that adult aquatic insects are an important prey item for lake rearing juveniles. Threespine Stickleback diets showed some overlap with diets of juvenile Sockeye Salmon; however, significant differences in diet composition suggest that Sockeye Salmon and Threespine Stickleback partition prey and habitat resources. I then used my field-derived temperature, demographic, and diet data as inputs to a bioenergetics model to estimate summer consumption rate and growth efficiency of juvenile Sockeye Salmon from Afognak Lake across a range of foraging scenarios. Consumption rate was greater and mean growth efficiency was lower for all littoral-use scenarios relative to pelagic-use scenarios. Further, daily consumption was lowest and mean growth efficiency was highest for model scenarios in which insects were a dominant component of the diet relative to scenarios in which zooplankton were the dominant prey. My findings highlight the importance of benthic-pelagic coupling in Sockeye Salmon nursery lakes and the potential for juveniles to navigate trade-offs between energy acquisition and thermal conditions across lake habitats.
