This book was released on 2018-01-14 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Success of Pink Salmon Spawning Relative to Size of Spawning Bed Materials Permeability of bottom materials is prob ably an important factor limiting fry production in spawning beds. It has been shown how permeability is related to size composition of bottom materials, and it is possible to compare relative permeability of spawning beds by determining average size composi tion. Hence, a simple and direct method of measuring physical properties of spawning beds pertaining directly to their capacity to produce fry has been provided through develop ing techniques for measuring size composi tion of bottom materials. Pronounced differences in size composition of bottom materials were observed among several pink salmon spawning streams. The more productive spawning streams had the highest permeability coefficients. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Synopsis Effects of Spawning Pacific Salmon on the Trophic and Population Ecology of Stream-resident Sculpins by : Noel Richard Swain

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the North Pacific coast, marine and freshwater ecosystems are linked by annual spawning runs of Pacific salmon. Although past research has highlighted the importance of these nutrient subsidies to freshwater food webs, their effects on the trophic and population dynamics of freshwater fish remain poorly understood. In this thesis I examined the relative influences of pink (Oncorhynchus gorbuscha) and chum (O. keta) salmon and habitat on the diets, individual condition, and population densities of freshwater prickly sculpins (Cottus asper), and coastrange sculpins (C. aleuticus). I found that sculpin condition and salmon nutrients in sculpin diets increased with the availability and density of spawning salmon, and were influenced by season, sculpin species, body size, and habitat. I also found that salmon density, pH, and habitat were related to sculpin population densities, but that their effects differed between sculpin species. This is the first study to test such relationships for freshwater fishes across wide, natural gradients in salmon spawning density and habitat.
