Molecular investigations of outbreaks of Perch perhabdovirus infections in pike-perch

Diseases of Aquatic Organisms, 2017
In 2016, a total of 5 massive mortality episodes each affecting hundreds of thousands of pike-perch Sander lucioperca larvae occurred at 2 sites in 2 Western European countries. For each episode, perhabdoviruses related to the perch rhabdovirus (PRV) were detected in samples, using either PCR or cell culture combined with PCR.

Holding on or heading up? The roosting preferences of brown- and white-feathered laying hen pullets [PDF]

Poultry Science
Although laying hens are known to be motivated to roost as high as possible and to use a perch that allows them to grasp, little is known about how these behaviours develop in young birds.

Similarity and Genetic Variation of Climbing Perch, Anabas testudineus (Bloch, 1792), From Java, Sumatra, and Kalimantan Islands, Indonesia [PDF]

Scientifica
Climbing perch, Anabas testudineus, is an economically important freshwater fish in Indonesia. The climbing perch, also known as betok, has emerged as a prominent species in aquaculture due to its air-breathing ability, which allows the climbing perch to

Altered Visual Function in Short-Wave-Sensitive 1 (sws1) Gene Knockout Japanese Medaka (Oryzias latipes) Larvae

Cells, 2023
Visual perception plays a crucial role in foraging, avoiding predators, mate selection, and communication. The regulation of color vision is largely dependent on opsin, which is the first step in the formation of the visual transduction cascade in ...

Transcriptome sequencing and metabolome analysis of food habits domestication from live prey fish to artificial diets in mandarin fish (Siniperca chuatsi)

BMC Genomics, 2021
Background As economical traits, food habits domestication can reduce production cost in aquaculture. However, the molecular mechanism underlying food habits domestication has remained elusive.

A New Lineage of Perch Rhabdovirus Associated with Mortalities of Farmed Perch [PDF]

Pathogens, 2021
A perhabdovirus was isolated from a mortality episode affecting a fish farm in 2019 in Western Europe. This virus was produced in cell culture and was readily detected by a species-specific real-time PCR assay. The near-complete sequence of the virus obtained showed some relatedness with viruses of the species Perhabdovirus perca.

Functional Characterization and Molecular Marker Development of the Proenkephalin as Biomarker of Food Addiction in Food Habit Domestication of Mandarin Fish (Siniperca chuatsi)

Fishes, 2022
Proenkephalin (PENK), as the precursor of endogenous opioid enkephalin (ENK), is widely present in the nervous system and plays an important role in animal food addiction and rewarding behavior.
