ZIMSEC O Level Geography Notes:Natural Resources: Fishing: Fishing methods
- Subsistence fishers use:
- basket traps,
- hooks and lines,
- scoops and dugout canoes.
- These are mainly confined to the shallow waters of Lakes Malombe, Chiuta, Chilwa in southern Malawi and swamps of the Lower Shire.
- The basket trap and fish scoop are made out of locally obtained bamboo or reeds which flourish in the swamps.
- Dug-out canoes are however more difficult to make as suitable trees are becoming scarce due to over-exploitation.
- These methods are sustainable as only limited catches are made from subsistence use.
- Commercial fishers use more modern methods of fiberglass motor boats.
- The gill net has an advantage of landing large catches.
- Its disadvantage is that it does not discriminate between mature fish and small fish which are yet to mature.
- The method is therefore not sustainable.
- Trawler boats and trawl nets are used in the deep waters of Lake Malawi
