1. Less is more: Negative relationship between biomass density and sea lice infestation in marine salmon farming

salmon,   etc   ; Salmonidae; biomass; farmers; mortality;     Show all 5 Subjects
Abstract:
... The relationship between biomass density and sea lice infestation is of particular interest in marine salmonid aquaculture. Data from a commercial fish farmer with parallel production of both organic and conventional salmon at the same site made it possible to study aspects of this relationship in a field situation. The maximum allowed biomass density for organically produced salmon is 10 kg/m³ an ...

Abstract:
... The restricted movement paradigm (RMP) asserts that stream fishes are sedentary, living much of their lives within a single reach. To test the RMP, we implanted eyed Atlantic salmon eggs (Salmo salar) into a total of 19 artificial redds, in seven salmon-free streams, in 6 years, and estimated summer fry dispersal through electrofishing surveys. As expected, most fry dispersed downstream, but an av ...

Abstract:
... Aquaculture governance can be challenging as a number of stakeholders have different objectives and visions for the industry. A license is an important tool in ensuring an orderly development of an industry, providing rights as well as obligations. However, the constraints imposed by a license can also prevent desirable activities. In the Norwegian aquaculture industry this has been addressed by c ...

Abstract:
... In 2020, the Alaska Board of Fisheries created a new personal use fishery on the Susitna River, effectively expanding the fishing opportunities for personal use fishermen in the already contentious atmosphere of Cook Inlet fishery allocation conflicts. The opening of this fishery happened in tandem with the removal of a “stock of yield concern” status for Susitna River sockeye and additional restr ...

Abstract:
... Video data are widely collected in ecological studies, but manual annotation is a challenging and time‐consuming task, and has become a bottleneck for scientific research. Classification models based on convolutional neural networks (CNNs) have proved successful in annotating images, but few applications have extended these to video classification. We demonstrate an approach that combines a standa ...

Like other First Nation communities, these nomadic people suffered decimation and disease in successive encounters with Europeans, and then, in the mid-twentieth century, forced sedentarization by the Chilean State. More recently, the Yagan have fought ...

Abstract:
... For many species, migrating at just the right time is essential for both survival and reproduction. A new study in salmon localizes a small genomic region associated with migration timing, which in turn affects other physiological traits, suggesting that a seemingly complex suite of migration traits is linked by one “simple” phenotype. ...

8. Bias in hatchery-origin coho salmon survival estimates due to underestimated prerelease mortality

Abstract:
... The widely accepted belief that hatchery-origin salmon survive less well than natural-origin or wild salmon can be, at least in part, an artifact of the way hatchery salmon survival is estimated. Hatchery salmon are often marked several months before release, while natural salmon are marked during their seaward migration. Underestimated prerelease mortalities result in biased low survival estimate ...

Identifying the sources of FMD is important to take the necessary actions to diminish their abundance. In 2019 eleven transects were opportunistically conducted to evaluate the abundance, spatial distribution an ...

Abstract:
... Scavenging, an underappreciated mechanism of prey consumption for many predators, can contribute substantially to nutritional intake. Facultative scavengers such as brown bears (Ursus arctos Linnaeus, 1758) may both kill and scavenge Pacific salmon (genus Oncorhynchus Suckley, 1861), though the extent of scavenging and factors affecting this behavior are unclear. We tagged 899 sockeye salmon (Onco ...
