Environmental DNA Detects Remaining Populations of Endangered Stream Salmon (Sichuan Taimen: Hucho bleekeri Kimura Salmonidae) in the Qinling Mountains

Fishes, 2023
Sichuan taimen (Hucho bleekeri Salmonidae) populations are declining, and the status of remnant populations in the Qinling Mountains is poorly known. In this study, eDNA and creel netting were used to estimate the distributions of Sichuan taimen in two ...

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

Cryopreservation of early-stage male Black Sea trout (Salmo trutta labrax) germ cells and comparison of the whole tissue and enzymatically isolated cells

Czech Journal of Animal Science
The high plasticity, or the ability to differentiate into various cell types, and capacity to become both gametes of early-stage germ cells (eGCs) allows them to be used for the long-term storage and recovery of genetic information.

Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

Methods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

Heart and skeletal muscle inflammation – novel dangerous disease of farmed Salmonidae

Ветеринария сегодня, 2020
Heart and skeletal muscle inflammation (HSMI) is one of the most widespread economically relevant diseases of farmed Atlantic salmon (Salmo salar), and it poses serious danger to its aquaculture. The disease was first reported in Norway in 1999. In 2006,

Heat exchange rates between adult sockeye salmon (Oncorhynchus nerka) and the environment

Journal of Fish Biology, EarlyView.
Abstract Body temperatures of salmon do not always match the temperatures of their immediate environment. We investigated the relationship between varying ambient water temperatures and body temperatures of adult sockeye salmon Oncorhynchus nerka using Newton's law of cooling and non‐linear mixed models.

Geographical distribution of Gyrodactylus salaris Malmberg, 1957 (Monogenea, Gyrodactylidae)

Parasites & Vectors, 2021
Background Gyrodactylus salaris Malmberg, 1957 is an OIE (Office International des Epizooties)-listed parasitic pathogen and had until the current study been reported from 19 countries across Europe, although many of these records require confirmation ...

Resource use by threatened, native Bull Trout (Salvelinus confluentus) in the presence of two non‐native salmonids

Journal of Fish Biology, EarlyView.
Abstract Introduction of non‐native species contributes to the global decline of freshwater fishes by disrupting the diet and resources of native species through competition. Despite the potential for non‐native trout (Family: Salmonidae) to compete with native trout, non‐native trout species have been widely introduced worldwide to support ...
