Amylase from Dog Salmon Oncorhynchus keta (WALBAUM)

NIPPON SUISAN GAKKAISHI, 1940
For the action of amylase from the pyloric coeca of dog salmon, Oncorhynchus keta (WALBAUN), the optimum temperature lies at about 20°C (Fig. 1), while the optimum hydrogen ionconcentration at 7•0 of pH-value (Fig. 2).

First Report of the Malacosporean Parasite Tetracapsuloides bryosalmonae in the Faroe Islands Reveals Widespread Distribution and High Prevalence in Brown Trout

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT The myxozoan endoparasite Tetracapsuloides bryosalmonae (Tb), the causative agent of proliferative kidney disease (PKD) in salmonids, has predominantly been reported in temperate regions of continental Europe and North America. Here, we present the first record of Tb in the Faroe Islands, extending the known northern distribution of the ...

Isolation of apolipoproteins from carotenoid-carrying lipoprotein in the serum of chum salmon, Oncorhynchus keta

Journal of Lipid Research, 1988
Carotenoid-carrying lipoprotein (CCL) was rapidly isolated from the high density lipoprotein (HDL) fraction of the upstream migrating male chum salmon (Oncorhynchus keta) by a single-step density gradient ultracentrifugation. The two apolipoproteins (Mr =

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, Volume 42, Issue 5, Page 1069-1082, June 2026.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Antioxidant Effect of a Marine Oligopeptide Preparation from Chum Salmon (Oncorhynchus keta) by Enzymatic Hydrolysis in Radiation Injured Mice

Marine Drugs, 2011
Marine oligopeptide preparation (MOP) obtained from Chum Salmon (Oncorhynchus keta) by the method of enzymatic hydrolysis, has been found to possess a radioprotective property through stimulation of the radiation-induced immunosuppression.

Role of the Trunk Musculatures in Oviposition of Chum Salmon, Oncorhynchus keta

NIPPON SUISAN GAKKAISHI, 1980
An electromyographic study was conducted on the female chum salmon which engaged in natural spawning in a small tank. Electrodes were implanted in the dorsal, ventral, and dark portions of the lateral trunk musculature (LTM) of the fish. It was found that every site of recording gave a strong burst of potentials (500-800 μV) lasting several seconds (3 ...

Infectious hematopoietic necrosis virus (IHNV) in fish and its consequences for fish farming: A comprehensive review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Viral diseases are a major concern in finfish aquaculture, leading to severe health problems. Infectious hematopoietic necrosis (IHN) is a highly transmissible systemic viral disease that primarily affects salmonids, causing significant mortality and economic losses to the salmonid farming industry.

Wood restoration results in rapid conversion of a degraded plane‐bed channel, Little River, Washington

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The authors document that wood restoration can rapidly and positively affect a number of geomorphic variables to improve habitat conditions for Pacific salmon. Abstract The loss of instream wood can create a legacy of channel incision that is detrimental to habitat formation.

Morphology and Distribution of Olfactory Receptor Neurons in Southern Bluefin Tuna, Thunnus maccoyii (Teleostei): Implications for Olfactory Hydrodynamics

Journal of Morphology, Volume 287, Issue 5, May 2026.
The number and distribution of olfactory receptors over the olfactory lamellar surface of four juvenile southern bluefin tuna were quantified using scanning electron microscopy. The microvillous olfactory receptors (mORN) are concentrated in the rostral region of the lamellar surface, while ciliated olfactory receptors (cORN), which are dominant in ...
