Fish Farming
This lesson covers:
- What fish farming is
- How saltwater fish can be grown in sea cages, using the example of salmon farming
- How freshwater fish can be grown in tanks or ponds, using the example of carp farming
- How fish stocks can be maintained through the use of sustainable fishing methods
Why do we farm fish?
Overfishing threatens the existence of many fish species in the wild.
We use fish farming and sustainable fishing methods as an alternative way of sourcing fish that avoids overfishing.
- Fish farms are large enclosures or tanks designed to provide controlled environments for the growth of fish for human consumption. Obtaining our fish from fish farms allows wild fish stocks to recover.
- Opting for fish sourced from sustainable fisheries, in addition to fish farming, helps maintain fish stocks.
Sustainable fisheries Adopting sustainable fishing methods preserves the health and biodiversity of aquatic ecosystems and safeguards the future of the fishing industry. |
Sustainable fisheries practices include:
|
How do sustainable fisheries contribute to the maintenance of fish stocks?
By encouraging overexploitation for short-term gains
By implementing fishing quotas for responsible harvesting
By decreasing net sizes
By ignoring the impact on juvenile fish
|
What is the purpose of increasing the size of fishing nets?
To decrease the size of fish populations
To capture more fish
To reduce the number of adult fish caught
To allow young fish to escape
|
What is the purpose of fishing quotas?
To increase the amount of fish caught
To maintain balanced ecosystems
To decrease the size of fish populations
