Sample interview questions: How do you assess and manage the impacts of invasive fish species in marine ecosystems?
Sample answer:
Assessing Impacts of Invasive Fish Species
- Monitor population dynamics: Track changes in abundance, distribution, and biomass over time to quantify the extent of invasion.
- Examine ecological interactions: Study the effects on native species, including competition for resources, predation, and habitat alteration.
- Assess environmental impacts: Evaluate changes in water quality, ecosystem structure, and biogeochemical cycles.
- Use genetic tools: Identify the source of invasion, genetic diversity within invasive populations, and potential hybridization with native species.
Managing Impacts of Invasive Fish Species
- Prevention: Implement measures to prevent new introductions, such as ballast water management, border inspections, and public education.
- Eradication and control: Consider removing small populations through physical or chemical methods, or implementing containment strategies to limit their spread.
- Adaptive management: Develop flexible … Read full answer
