CAIE IGCSE Biology EXTENDED 20.4.6 Fish stocks can be conserved using
Practise interpreting fish-stock data and explaining how quotas, closed seasons, protected areas, mesh size, education and monitoring reduce overfishing.
How this is tested
- interpret fish population graphs after quotas, bans or restocking measures
- explain how mesh size, closed seasons and quotas allow young fish to reproduce
- use data tables to state percentages or time periods for sustainable fish stocks
