Carcinogens and Cancers in Freshwater Fishes [PDF]

Environmental Health Perspectives, 1991
Epizootics of neoplasms in freshwater fish species are considered in relation to circumstantial and experimental evidence that suggest that some epizootics of neoplasia of hepatocellular, cholangiocellular, epidermal, and oral epithelial origin may be causally related to contaminant exposure.

Colossal Aggregations of Giant Alien Freshwater Fish as a Potential Biogeochemical Hotspot [PDF]

, 2011
The ubiquity and fascinating nature of animal aggregations are widely recognised. We report here consistent and previously undocumented occurences of aggregations of a giant alien freshwater fish, the Wels catfish (Silurus glanis).

Optimal reference genes for gene expression analysis in polyploid of Cyprinus carpio and Carassius auratus

BMC Genetics, 2020
Background Reference genes are usually stably expressed in various cells and tissues. However, it was reported that the expression of some reference genes may be distinct in different species.

Land use, associated eel production, and abundance of fish and crayfish in streams in Waikato, New Zealand [PDF]

, 1997
The density and biomass of fish and crayfish, and the production of eels, was compared among streams in native forest, exotic forest, and pasture. Populations were estimated by multiple-pass electroshocking at 11 sites in hill-country streams in the ...

Interactions between mitochondrial and nuclear genomes and co-regulation of mitochondrial and nuclear gene expression in reciprocal intergeneric hybrids between Carassius auratus red var. × Cyprinus carpio L.

Reproduction and Breeding, 2021
Genetic interactions between nuclear and mitochondrial genomes always play an important role in growth and development. However, it is not feasible to directly perform these studies in some animals. The reciprocal hybrid fishes obtained from intergeneric

Baseline study on the freshwater ornamental fish industry in Palawan, Philippines. [PDF]

, 2022
The status of both freshwater and marine ornamental fish industries in the Philippines has been assessed in 2019; however, Palawan was excluded due to the unavailability of data with regard to the ornamental fish trade.

Symmetric subgenomes and balanced homoeolog expression stabilize the establishment of allopolyploidy in cyprinid fish

BMC Biology, 2022
Background Interspecific postzygotic reproduction isolation results from large genetic divergence between the subgenomes of established hybrids. Polyploidization immediately after hybridization may reset patterns of homologous chromosome pairing and ...

Exogenous paternal mitochondria rescue hybrid incompatibility and the destiny of exogenous mitochondria

Reproduction and Breeding, 2022
The mitochondria of most organisms follow strict maternal inheritance, and the mechanism of elimination of paternal mitochondria is unclear. Our previous studies showed that the paternal mtDNA presented in the embryo of hybrid Megalobrama Amblycephala ...

Diseases of freshwater fish

Veterinary Quarterly, 1996
Dust and endotoxin exposure was measured in the Spring and Autumn in 96 veterinary practitioners, subdivided in four professional groups ((predominantly working with either swine, cattle, poultry, or companion animals). Furthermore, peak expiratory flow (PEF) variability was measured four times a day over a week in Spring and Autumn in order to detect ...

Introduced Pathogens and Native Freshwater Biodiversity: A Case Study of Sphaerothecum destruens [PDF]

, 2012
A recent threat to European fish diversity was attributed to the association between an intracellular parasite, Sphaerothecum destruens, and a healthy freshwater fish carrier, the invasive Pseudorasbora parva originating from China.
