Outbreak of mortality in Russian (Acipenser gueldenstaedtii) and Siberian (Acipenser baerii) sturgeons associated with sturgeon nucleo-cytoplasmatic large DNA virus [PDF]

Veterinary Microbiology, 2016
Diseased outbreaks with high mortality in farmed sturgeon are a limiting factor to the success of this emerging aquaculture sector in Europe. Thorough investigations of outbreaks can determine the aetiological agents, identify important pathological and epidemiological pathways of infections and pave the way for effective control strategies. A thorough

River Network Connectivity Reductions Dominate Declines in the Richness of Plateau Fish Species Under Climate Change in the Upper Yangtze River Basin

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Anthropogenic climate change and disrupted river network connectivity are major factors affecting freshwater fish richness. However, the distribution patterns of this parameter under the combined influence of climate change and reduced river connectivity resulting from hydroelectric development remain unclear.

Growth modeling of the European grayling (Thymallus thymallus L.) in a large alpine river based on age‐at‐length, mark‐recapture, and length‐frequency data

Journal of Fish Biology, Volume 106, Issue 6, Page 1714-1723, June 2025.
Abstract Animal growth is a fundamental component of population dynamics, which is closely tied to mortality, fecundity, and maturation. As a result, estimating growth often serves as the basis of population assessments. In fish, analysing growth typically involves fitting a growth model to age‐at‐length data derived from counting growth rings in ...

Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses?

Global Change Biology, Volume 31, Issue 5, May 2025.
Nearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

Long Distance Migration of Beluga (Huso huso) and Stellate Sturgeon (Acipenser stellatus) in Lower Danube River in Relation with Iron Gate II Dam

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2018
Construction of the dams in Lower Danube River (LDR- rkm 0 Sulina – rkm 1075 Baziasi) without fish passages, as well as illegal fishery and river bottom modification due to navigation had negative impact on sturgeon’s populations.

Melanin and Neurotransmitter Signalling Genes Are Differentially Co‐Expressed in Growing Feathers of White and Rufous Barn Owls

Pigment Cell &Melanoma Research, Volume 38, Issue 2, March 2025.
The colouration of the ventral face of barn owls varies from white to rufous, depending on the MC1R (V126I) genotype. This colouration is linked to multiple fitness and behavioural traits. Genes linked to neurotransmitters and synapses are upregulated with melanin genes in a transcriptome of growing feathers from the ventral part of chicks of the ...

An In‐Depth Analysis of the Finfish Aquaculture in Türkiye: Current Status, Challenges, and Future Prospects

Reviews in Aquaculture, Volume 17, Issue 2, March 2025.
ABSTRACT Aquaculture emerges as a crucial solution for addressing the global food shortage of an estimated 10 billion people by 2050. In Türkiye, aquaculture plays a significant role in supporting the economy and ensuring food security. Over the past two decades, finfish production in Türkiye surged from 61,163 to 547,505 t, generating $1.7 billion in ...
