Aquakultur Quiz und Flashcards: Lerne alles über nachhaltige Fischerei

Study Notes

Fish Farming Impacts

Environmental impacts:
- Escaped farmed fish can interbreed with wild fish, altering gene pools
- Farm waste and excess feed can lead to water pollution and algal blooms
- Habitat destruction and alteration of coastal ecosystems
Disease and parasite transmission:
- Farmed fish can transmit diseases and parasites to wild fish
- Increased risk of disease outbreaks in farmed fish populations
Social impacts:
- Displacement of local communities and traditional fishing practices
- Dependence on imported feed and energy resources

Aquaculture Technology

Recirculating aquaculture systems (RAS):
- Closed-loop systems that recycle water and waste
- Reduced water usage and waste discharge
- Improved water quality and fish health
Integrated multi-trophic aquaculture (IMTA):
- Combination of different species and trophic levels in the same system
- Improved water quality and reduced waste
- Increased biodiversity and ecosystem services
Genetic improvement and selection:
- Breeding programs for improved growth rates, disease resistance, and feed efficiency
- Genetic selection for desirable traits and reduced environmental impact

Marine Ecosystem Management

Marine protected areas (MPAs):
- Designated areas that protect marine biodiversity and ecosystems
- Reduced human impact and habitat destruction
- Improved fisheries management and conservation
Ecosystem-based fisheries management:
- Holistic approach to managing fisheries, considering ecosystem interactions and impacts
- Improved understanding of ecosystem dynamics and resilience
- Reduced bycatch and habitat damage
Coastal zone management:
- Integrated management of coastal resources and activities
- Balanced development and conservation of coastal ecosystems
- Reduced conflict and improved stakeholder engagement

Fish Population Management

Stock assessment and monitoring:
- Regular monitoring of fish populations and biomass
- Improved understanding of population dynamics and trends
- Data-driven fisheries management decisions
Catch limits and quotas:
- Regulation of fishing effort and catch to prevent overfishing
- Improved conservation of fish populations and ecosystems
- Reduced risk of fishery collapse
Fisheries closures and rebuilding plans:
- Temporary or permanent closures of fisheries to allow for rebuilding
- Rebuilding plans for depleted fish populations
- Improved long-term sustainability of fisheries

Sustainable Fishing Practices

Selective fishing gear:
- Gear designed to reduce bycatch and protect non-target species
- Improved fishing efficiency and reduced waste
- Reduced impact on marine ecosystems
Eco-labeling and certification:
- Labels and certifications that recognize sustainable fishing practices
- Improved market access and consumer awareness
- Incentivized sustainable fishing practices
Fishing gear innovation:
- Development of new gear technologies that reduce environmental impact
- Improved fishing efficiency and reduced waste
- Reduced bycatch and habitat damage
