Over the last four decades, the aquaculture sector especially in developing countries has experienced dramatic growth. The increase in aquaculture production is a combination of area expansion and technological change (enhanced strains, input of feed and fertilizer, and improved management). One example of such technological change is the selective breeding...
Cell culture systems have provided many insights into
eukaryotic gene expression and other biochemical
mechanisms. Since the cell represents the smallest living
unit of any organism it provides a desirable in vitro
system, allowing biochemical studies without the complex
physiology of an entire animal. However, processes
involving intracellular mechanisms, such...
Identifying appropriate units for conservation requires knowledge of evolutionary
patterns and risks of managing at different geographical and genetic scales. I examined
genetic diversity at different geographical scales among 11,400 rainbow trout
(Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of
their range and among coho...
Molecular biological approaches were used to study and interfere with the life
cycle of infectious hematopoietic necrosis virus (IHNV). These included the control
of IHN disease in rainbow trout by genetic immunization or interference in vitro by
synthesis of sense and antisense expression of the viral nucleocapsid (N) gene, and...
Most benthic marine organisms have a bipartite life with an early pelagic stage that enables dispersal of offspring, connecting spatially separated populations, and a late stage where individuals reside in a benthic habitat. Settlement of pelagic offspring to bottom associated substrates is the process that connects the two life history...
