Food Production (fish) Flashcards
1
Q
Benefits of Fish Farming
A
- Ability to selectively Breed
- Protect against Predators
- Control water quality
- Control feeding
2
Q
Methods for hight yield
A
- Control water quality
- Control Intraspecific predation
- Control Interspecific predation
- Control of disease
- Control and removal of waste
- Control quality and frequency of feeding
- Use of Selective breeding
3
Q
Maintenance of water quality
A
- Water is filtered to remove waste to avoid disease
- Cleaned to maintain high oxygen levels
4
Q
Control of Intraspecific Predation
A
- Separated by age and size so predation doesn’t occur between the same species
5
Q
Control of interspecific predation
A
- Different species separated by fences to avoid predation between different species
6
Q
Control of Disease
A
- Antibiotics given to prevent disease
- Kept in small numbers to avoid spread
7
Q
Removal of waste
A
- Water is filtered to remove sewage
- Tanks are cleaned or fish are moved periodically
8
Q
Quality and frequency of feeding
A
- Fed food high in nutrients for fast growth
- Fed frequently in small amounts to avoid overeating or cannibalism
9
Q
Selective breeding
A
- Separated by gender so farmers can only allow fish with certain characteristics to breed
- Ensures faster passing of Genes
