Opening a can of worms: Archived canned fish fillets reveal 40 years of change in parasite burden for four Alaskan salmon species

Ecology and Evolution
How has parasitism changed for Alaskan salmon over the past several decades? Parasitological assessments of salmon are inconsistent across time, and though parasite data are sometimes noted when processing fillets for the market, those data are not ...

Some Diagnosis and Therapy Techniques in Rainbow Trout (Oncorhynchus Mykiss) Furunculosis, in Intensive System Bred

Scientific Papers Animal Science and Biotechnologies, 2023
Clinical and paraclinical investigations (morpho-pathologic, bacterioscopic, bacteriologic and sensitiveness test to antibodies) done on 20 fish (rainbow trout), dead or in agony state, taken from a furunculosis pesthole in Salmonidae and proceeded from ...

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Comparative study of blood biochemistry in clinically healthy farmed barramundi (Lates calcarifer) and rainbow trout (Oncorhynchus mykiss) from freshwater recirculating aquaculture systems

Australian Veterinary Journal, EarlyView.
Barramundi (Lates calcarifer) is an economically significant aquaculture species and ranks among Australia's top five farmed finfish. As global production intensifies, understanding the physiology and health of barramundi is essential to support animal welfare and industry profitability.

Management strategy evaluation for salmon habitat restoration and hatchery supplementation

Conservation Science and Practice, EarlyView.
Building on three previously published studies, this paper applies population modeling work to evaluate the effects of different habitat and hatchery management strategies on achieving recovery goals for endangered Chinook salmon. We find that it would require a >150% improvement in juvenile survival to achieve recovery goals for population abundance ...

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Egg Lipids of a Salmon, Oncorhynchus keta-II

NIPPON SUISAN GAKKAISHI, 1958
Unfertilized and fertilized (after 24 hours) salmon eggs, previously treated with acetone, were successively extracted with ethanol, petroleum ether and finally with boiling ethanol to yield lecithins, cephalins and sphingolipids as shown in Fig. 1.

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

Fish and Fisheries, EarlyView.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform

Environmental DNA Reflects Differences in Freshwater Habitat Use Between Two Pacific Salmonids at Fine Temporal Scales

Environmental DNA
Environmental DNA (eDNA) has emerged as a powerful tool to detect aquatic species, providing a non‐invasive survey option for applications in freshwater fisheries, including delineating habitat use and informing stock management strategies.

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

Fisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing
