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.

Effective monitoring of freshwater fish [PDF]

Fish and Fisheries, 2019
AbstractFreshwater ecosystems constitute only a small fraction of the planet's water resources, yet support much of its diversity, with freshwater fish accounting for more species than birds, mammals, amphibians or reptiles. Fresh waters are, however, particularly vulnerable to anthropogenic impacts, including habitat loss, climate and land use change,

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 ...

Freshwater fish diversity information system as a basis for sustainable fishery [PDF]

, 2004
Our freshwater fish diversity is poorly studied. There is no proper documentation on freshwater fish resources of India. Due to irrational fishing practices, environmental aberrations like reduction in water volume, increased sedimentation, water ...

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

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 ...

Rapid genomic DNA variation in newly hybridized carp lineages derived from Cyprinus carpio (♀) × Megalobrama amblycephala (♂)

BMC Genetics, 2019
Background Distant hybridization can generate changes in phenotypes and genotypes that lead to the formation of new hybrid lineages with genetic variation.

Heterosis of growth trait regulated by DNA methylation and miRNA in allotriploid fish

Epigenetics & Chromatin, 2022
Background Heterosis of growth traits in allotriploid fish has benefited the production of aquaculture for many years, yet its genetic and molecular basis has remained obscure.
