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 …

Puberty comprises the transition from an immature juvenile to a mature adult state of the
reproductive system, ie the individual becomes capable of reproducing sexually for the first …

Rapid decreases in water temperature may result in a number of physiological, behavioural
and fitness consequences for fishes termed 'cold shock'. Cold‐shock stress occurs when a …

The book is a detailed risk assessment and biological synopsis of the bigheaded carps of
the genus Hypophthalmichthys, which includes the bighead, silver, and largescale silver …

The aim of this review was to highlight the extent to which the genetic technologies are
implemented by the aquaculture industry. The review shows that some of the modern …

Whole genome duplication (leading to polyploidy) is widely accepted as an important
evolutionary force in plants, but it is less recognized as a driver of animal diversification …

The purpose of this review is to introduce recent advances in research, development and
application of chromosome manipulation techniques in Japan. Triploids have been induced …

Fish species that have external fertilization can be reproduced by induced parthenogenesis.
The nuclear content of either the sperm or egg is destroyed by UV or gamma irradiation, and …

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 …

Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐
term sustainable approach to meet the rising global demand for seafood. During the …
