Spatio-temporal migration patterns of Pacific salmon smolts in rivers and coastal marine waters. [PDF]

PLoS ONE, 2010
BACKGROUND: Migrations allow animals to find food resources, rearing habitats, or mates, but often impose considerable predation risk. Several behavioural strategies may reduce this risk, including faster travel speed and taking routes with shorter total

Estimation of abundance for migrating juvenile pink salmon in the rivers of Sakhalin and Iturup Islands in 2023

Известия ТИНРО
Number of juvenile pink salmon migrated from the spawning grounds in the rivers of East Sakhalin (Dagi, Malaya Khuzi, Kholodny (tributary of Poronay), Lazovaya, Pugachevka, Voznesenka, Ochepukha, Taranai, and Kura) and Iturup Island (Rybatskaya and Olya)

Ages at maturation of tropical freshwater eels, Anguilla bicolor bicolor and A. bengalensis bengalensis

Journal of Applied Animal Research, 2018
Freshwater eels are one of the world’s most valuable cultured fish species. However, there is little information available on the biological characteristics of tropical anguillid eels genus Anguilla in the silver (maturation) stage even though these ...

Downstream migration and mechanisms of dispersal of young fish in rivers [PDF]

Canadian Journal of Fisheries and Aquatic Sciences, 2017
Downstream migration (DSM) of young fish has traditionally been considered a passive process. A review of studies of the patterns and mechanisms of DSM showed that it met the main criterion for migration: that animals move between well-defined habitats according to a predictable schedule.

Estimation of abundance for the migrating juvenile pink salmon in the rivers of Sakhalin and Iturup Islands in 2024

Известия ТИНРО
Pink salmon is the leading object of salmon fishery in the Sakhalin-Kuril region. To forecast the status of its stocks, the number of juveniles migrated downstream was counted in the rivers Dagi, Malaya Khuzi, Pugachevka, Voznesenka, Ochepukha, Taranai ...

Effects of high water level on the river residence period of juvenile Chinese sturgeon Acipenser sinensis in the Yangtze River

Knowledge and Management of Aquatic Ecosystems, 2012
The migration time of newly hatched Acipenser sinensis from the spawning area (river km 1675) to the Yangtze estuary (rkm 0) was ascertained in the years 1996–2007 (time range 192–243 days), and its relationship to water levels surveyed at 12 typical ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Étude du comportement de smolts de saumon atlantique (Salmo salar L.) au niveau de la prise d'eau de l'usine hydroélectrique de Pointis sur la Garonne et estimation de la dévalaison au niveau du barrage de Rodère

Knowledge and Management of Aquatic Ecosystems, 1999
Une expérimentation a été menée en 1998 au niveau de la prise d'eau de l'usine hydroélectrique de Pointis, sur la Garonne, de manière à déterminer, grâce à la technique de radio-pistage, le meilleur emplacement d'un futur dispositif de dévalaison.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
