Repeat spawning of the Atlantic salmon (Salmo salar) in various salmon rivers in Iceland
Information on repeat spawning in Atlantic salmon stocks from eight various rivers in Iceland was analyzed, using data collected by the Institute of Freshwater Fisheries in Iceland. The rivers differ in characteristics as well as location based on bedrock and geographical area. Available data from …

Salmon & Steelhead Hatcheries: Conservation or Condemnation?
Wild salmon and steelhead are as fundamental to the Pacific Northwest as evergreen trees and rain. For thousands of years ecosystems and economies have relied on the bountiful marine nutrients annually running inland from the Pacific Ocean in the form of large, silver fish. Even today, the chance …

Molecular analysis of the salmon pathogen Piscirickettsia salmonis
Piscirickettsia salmonis is the causative agent of Piscirickettsiosis, a disease causing significant losses in salmon aquaculture in Chile and which has also been isolated in salmonids in several other countries. This investigation was designed to prepare a recombinant library of P. salmonis DNA in …

Thyroid in intestinal development during atlantic salmon smoltification
Atlantic salmon (Salmo salar L.) has a complex lifecycle. It starts its life in FW, grows, and after several changes at behavioral, morphological, and physiological levels, a process called smoltification, the fish migrate downstream to the sea. During this process of seawater (SW) acquisition, the …

WTP for RAS salmon by the US consumer
… EPA and DHA in the U.S. diet is farmed Atlantic salmon, which has shown a steady consumption growth in the past decade. The U.S. shows the most production potential for salmon produced with an emerging production method, recirculating aquaculture systems (RAS), which directly addresses the …

Lepeophtheirus salmonis, parasitizing three species of pacific salmon (Oncorhynchus spp.): host variations in load, morphology, fecundity, and genetics of the salmon louse
… study is to determine biological parameters of salmon lice (Lepeophtheirus salmonis) as they parasitize different species of Pacific Ocean salmonids off the north Pacific coast of Washington State. Parasite load counts of L. salmonis were made and individuals were collected from salmonids in …

Using simulation to predict performance of salmon portioning line
… to determine the optimum setup for an automatic salmon portioning cutter. The objective is to determine what salmon sizes are best suited for different products and how the input into the system could be altered based on different scenarios. A second objective is to see how it affects the …

The Ecology of Parafluvial Ponds on a Salmon River
… Kwethluk River, I observed thousands of juvenile salmon apparently trapped by surface disconnection of the ponds from the river. I was interested in whether the salmon could survive until flooding reconnected the ponds to the river. I sampled ponds along the river corridor to describe habitat …
