Chapter 4. Evolutionary forces at work in fish populations

Jorge Santos

Full Text:




This chapter of CONΣERV IT deals with the following questions in aquatic conservation:

- How do escapees from aquaculture affect genetically salmon populations in rivers?
- What are the time-scales of change in the gene pool of fish?
- Can we eradicate undesirable traits from fish stocks?
- Are small populations more or less affected by immigration?
- What genetic diversity can we expect from large stocks in the sea?
- How much, and how to avoid inbreeding in broodstocks used in fish farming?
