Fish Diversity in a Little-Known Border River Between China, North Korea, and Russia, According to Traditional and eDNA Surveys

Diversity
The Tumen River, which delineates the border between China, North Korea, and Russia, is a vital river in Northeast Asia. Understanding its current fish diversity holds significant scientific value for aquatic ecological protection. Therefore, traditional

Salmon as an ecological pathway of contaminants into Alaskan food webs

Emerging Contaminants
Salmon are important fish taxa for humans and animals in hemiboreal and subarctic ecosystems. The presence of trace elements and their bioaccumulation across a marine food web raises potential health risk concerns associated with human consumption ...

Траектории миграций амурской горбуши Oncorhynchus gorbuscha к районам размножения

Известия ТИНРО (Тихоокеанского научно-исследовательского рыбохозяйственного центра), 2016
Biannual sequence of high-numerous and low-numerous year-classes of pink salmon ( Oncorhynchus gorbuscha ) is disturbed rarely in the areas close to its spawning grounds where mostly local groupings are landed, as it is shown on the data of fishery statistics in many areas of Russian Far East for 1907-1986.

Fishes
Atlantic salmon (Salmo salar) populations in the Arctic River Teno (Tana) and other North Atlantic rivers have declined at the same time as pink salmon (Oncorhynchus gorbuscha) have begun to spawn extensively in these rivers in odd-numbered years. In the

Биологическое разнообразие самок и самцов североохотоморской горбуши Oncorhynchus gorbuscha

Известия ТИНРО (Тихоокеанского научно-исследовательского рыбохозяйственного центра), 2007
С использованием морфологического, генетического и фенетического методов оценено биологическое разнообразие популяции горбуши р. Ола (северное побережье Охотского моря). Обнаружены статистически значимые различия между самками и самцами горбуши по показателям линейного, весового и генетического разнообразия (по частотам гена MDH-B1,2* в 2001 г.).
