Expression of RING Finger Protein 38 in Serotonergic Neurons in the Brain of Nile Tilapia, Oreochromis niloticus

Frontiers in Neuroanatomy, 2018
Serotonin (5-hydroxytryptamine, 5-HT) is one of the major neurotransmitters, modulating diverse behaviours and physiological functions. Really interesting new gene (RING) finger protein 38 (RNF38) is an E3 ubiquitin ligase whose function remains unclear.

The Segment Matters: Probable Reassortment of Tilapia Lake Virus (TiLV) Complicates Phylogenetic Analysis and Inference of Geographical Origin of New Isolate from Bangladesh

Viruses, 2020
Tilapia lake virus (TiLV), a negative sense RNA virus with a 10 segment genome, is an emerging threat to tilapia aquaculture worldwide, with outbreaks causing over 90% mortality reported on several continents since 2014.

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

Fisheries Oceanography, EarlyView.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Measurement of Auditory Thresholds of the Tilapia Tilapia niloticus.

NIPPON SUISAN GAKKAISHI, 1995
Auditory thresholds of the tilapia Tilapia niloticus in a quiet water tank were investigated using a classical conditioning procedure in a stable temperature container converted into an acoustic chamber. The classical conditioning procedure followed Ishioka's method.

Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

Journal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Adaptation, growth and survival of tilapia (Oreochromis niloticus) in Bafgh brackish water

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2013
An experiment was conducted to evaluate the possibility of adaptation, growth and survival of Nile tilapia (Oreochromis niloticus) with 0.3g initial weight and red tilapia (Oreochromis sp.) with 0.7g initial weight in underground brackish water. Fry of

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

A wild‐caught rosy barb Pethia conchonius in a British urban pond underscores the need to prevent aquarium releases

Journal of Fish Biology, EarlyView.
Abstract A specimen of rosy barb Pethia conchonius of 51 mm standard length, encountered in an urban pond in London, is reported. This small cyprinid is native to lakes and streams in subtropical regions of southern Asia and is commonly sold as an ornamental fish.

Host genetic selection for cold tolerance shapes microbiome composition and modulates its response to temperature

eLife, 2018
The hologenome concept proposes that microbes and their host organism are an independent unit of selection. Motivated by this concept, we hypothesized that thermal acclimation in poikilothermic organisms, owing to their inability to maintain their body ...
