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 …

Generating breeding programmes that effectively improve farmed fish performance across
multiple environments and make fish more uniform within production environments would …

Males and females often differ in their fitness optima for shared traits that have a shared
genetic basis, leading to sexual conflict. Morphologically differentiated sex chromosomes …

QTL are quantitative trait loci: genetic loci that contribute to variation in a quantitative trait.
QTL mapping is the effort to identify QTL through an experimental cross. In this book, we …

Salmonid fishes exhibit extensive local adaptations owing to abundant environmental
variation and precise natal homing. This extensive local adaptation makes conservation and …

Rapid adaptation to novel environments may drive changes in genomic regions through
natural selection. Such changes may be population-specific or, alternatively, may involve …

Migration is essential for the reproduction and survival of many animals, yet little is
understood about its underlying molecular mechanisms. We used the salmonid …

Little is known of the genetic basis of migration despite the ecological benefits migratory
species provide to their communities and their rapid global decline due to anthropogenic …

The present study evaluated the effects of biofloc technology (BFT) application on African
catfish (Clarias gariepinus) fingerling production with more focus given to the reproductive …

The timing and propensity for migration between fresh-and seawater is a key theme in the
diversity of life histories within the salmonid fishes. Across salmonid species, life-history …
