Workshop Module 11: Aquaculture 305- Water cleaning functions to remove excess nutrients and toxins.
- Shade.
- Food for people.
Water animals like water snails, small prawns, frogs, and other small animals are food for
some larger fish like catfish and help to keep an aquaculture system healthy.
Step 4: Provide homes for the fish
- Small fish sometimes need protection from bigger fish, especially if the fish eat
other fish. - A place for fish to make their nests is also needed.
- All water animals are healthier if they have a good habitat.
Step 5: Plants around the pond edge
- Plant around the edges of the pond immediately to hold the soil and prevent
erosion. - Pond edges make excellent production areas because the plants receive lots of
water and nutrients.
Step 6 - Add the fish
This is the subject of the next presentation. See the “Fish production” section of
PC Book MOD 11 – Aquaculture for more information about all these steps including
the amounts of the different materials needed.
