The migration of anadromous fish in heterogenic environments unceasingly imposes a selective pressure that results in genetic variation for local adaptation. However, discrimination of anadromous fish populations by fine-scale local adaptation is challenging because of their high rate of gene flow, highly connected divergent population, and large population size. Recent advances in next-generation sequencing (NGS) have expanded the prospects of defining the weakly structured population of anadromous fish.
Continued growth of the aquaculture sector will rely on the availability of fish with traits that respond to the needs and preferences of these users along the value chain. Such trait responsiveness requires that fish breeding programmes have reliable knowledge of these users’ trait preferences. The present study found from a non-systematic literature review, that no fish breeding programme had reported user preference in their product-profile design.
