Climate Change Impact on Aquaculture
15
Flashcards
0/15
Sea Level Rise
Flooding of coastal aquaculture facilities, salinity changes, and adaptation through elevated infrastructure and improved drainage systems
Acid Rain
Lowered pH levels in freshwaters, shell damage in mollusks, and buffering systems as well as watershed management to mitigate effects
Ocean Acidification
Decreased shellfish growth, disrupted sensory abilities in fish, and potential mitigation through selective breeding and buffering agents
Increasing Water Temperatures
Altered growth rates, increased vulnerability to diseases, and mitigation via selective breeding and temperature-controlled aquaculture systems
Extreme Weather Events
Damage to infrastructure, disruption of supply chains, and resilience through robust design and emergency preparedness plans
Coral Bleaching
Impact on reef ecosystems critical for certain fish species, causing reduced biodiversity and mitigation by reducing other stressors and reef restoration
Hypoxia
Reduced oxygen availability leading to increased mortality, and countermeasures like aeration technologies and water quality monitoring systems
Ocean Deoxygenation
Threat to aerobic aquatic organisms, forced migration or death, and response through habitat enhancement and oxygenation equipment
Algal Blooms
Toxicity issues for shellfish, blocked sunlight, and approaches to control through nutrient level management and early warning systems
Shifts in Fish Migration Patterns
Disruption to natural breeding areas, challenges for wild catch supplies, and adaptive strategies through ecosystem monitoring and habitat management
Increasing Ocean Stratification
Fewer nutrients in surface layers, affecting feed availability for farm-raised fish, and response with artificial feeding strategies and nutrient cycling
Dissolved Carbon Dioxide Increase
Adverse effects on fish metabolism and stress responses, with potential adaptations including advanced monitoring systems and bicarbonate supplementation in water
Changes in Salinity
Physiological stress on aquaculture species, potential loss of productivity, and intervention by selective breeding for salinity tolerance and salinity control systems
Sea Ice Loss
Reduction in polar habitats and changes in species distribution, with strategies including diversification of species farmed and shifts in operational locations
Phenological Shifts
Altered timing of breeding and migration cycles, potential mismatch in food chain, and adaptability through controlled breeding programs and diet supplements
