Tryptophan requirement of chum salmon fry.

open access: yesNIPPON SUISAN GAKKAISHI, 1985
Quantitative tryptophan requirement of chum salmon Oncorhynchus keta fry was determined by feeding purified diets containing crystalline L-amino acids and 5% casein as nitrogen sources for 4 weeks. The basal diet was isonitrogenously supplemented with graded levels (0.05, 0.08, 0. 16, 0.24, 0.32, 0.40, 0.48 and 0.56% in diet) of tryptophan by adjusting

Factors controlling the year-classes strength for chum salmon Oncorhynchus keta in the Okhotsk district

open access: yesИзвестия ТИНРО, 2023
A quasi-cyclicity associated with variability of environmental conditions is detected for the regression residuals of the stock-recruitment model for chum salmon Oncorhynchus keta in the Okhotsk district, described by Ricker’s equation.

Landscape Structure and Species Interactions Drive the Distribution of Salmon Carcasses in Coastal Watersheds

open access: yesFrontiers in Ecology and Evolution, 2019
The disproportionate effects of some species can drive ecosystem processes and shape communities. This study investigates how distributions of spawning Pacific salmon within streams, salmon consumers, and the surrounding landscape mediate the ...

BASIS FOR SELECTION OF RIVERS FOR MONITORING ON THE STOCKS OF CHUM AND PINK SALMON IN THE AMUR RIVER

open access: yesИзвестия ТИНРО, 2019
The monitoring of chum and pink salmon escapement to spawning grounds in the Amur River basin was stopped in 2009. To start it again, a proved choice of the rivers is necessary for adequate controlling of these species number, by the spawning habitats of

Characteristics of spawners of chum salmon Oncorhynchus keta from commercial stock of Iturup Island

open access: yesИзвестия ТИНРО, 2023
Chum salmon spawners returned for spawning in the rivers of Prostor and Kurilsky Bays on Iturup Island (Kuril Islands, Sakhalin Region) were examined in the period from September 19 to November 4, 2022. Both females and males had mostly the age 3+ (68.8 %

CHEMICAL COMPOSITION AND ENERGY CONTENT OF PACIFIC SALMONS IN THE OKHOTSK SEA

open access: yesИзвестия ТИНРО, 2019
The main bioenergetic parameters of pacific salmons are presented on the data obtained in marine expeditions in 2003–2015. Among the examined species, the minimum energy content is registered in the muscle tissue of chum salmon and pink salmon, and the ...

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

open access: yesFood Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Comparative studies of effect of compound feeds on fish-breeding and biochemical properties of juvenile chum salmon

open access: yesИзвестия ТИНРО, 2023
Effectiveness of starter fodders is examined for the low-temperature rearing pools in the salmon fish hatchery Savushkina (Severo-Kurilsk). In May 2022, the experimental compound feed developed in TINRO was compared with the control fodder Aller Aqua ...

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

open access: yesAgricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.
