Fish biology has been developed for more than 100 years, but some important
breakthroughs have been made in the last decade. Early studies commonly concentrated on …

Fisheries is a social production sector that captures and farms fish and other aquatic animals
and plants for aquatic products. In a broad sense, fisheries also include upstream …

Polyploids can be defined as organisms with one or more additional chromosome sets with
respect to the number most frequently found in nature for a given species. Triploids …

Hybridization is widely used. However, for a long time, systematic theories and technologies
related to hybridization in fish have been lacking. In this study, through long-term systematic …

Distant hybridization makes it possible to transfer the genome of one species to another,
which results in changes in phenotypes and genotypes of the progenies. This study shows …

Polyploidy is much rarer in animals than in plants but it is not known why. The outcome of
combining two genomes in vertebrates remains unpredictable, especially because …

Hybridization can combine the advantages of different strains to produce new varieties,
which may also improve the quality of fish. Triploid common carp (3n= 150) were derived …

Polyploids are organisms with three or more complete chromosome sets. Polyploidization is
widespread in plants and animals, and is an important mechanism of speciation. Genome …

Sexual vs. asexual reproduction—unisexual vs. bisexual populations—diploid vs. polyploid
biotypes—genetic vs. environmental sex determination: all these natural phenomena are …

This study provides genetic evidences at the chromosome, DNA content, DNA fragment and
sequence, and morphological levels to support the successful establishment of the polyploid …
