Aquaculture
Aquaculture is a boom industry globally; driven by increased demand for seafood, and reducing natural resources.
Many of the world's rivers, oceans and lakes have been over fished; and current predictions indicate that most of the fish and crustaceans we eat will eventually need to be farmed, rather than coming from natural resources.
There are three ain requirements for aquaculture:
1. Contained area (eg. ponds, caged areas natural bodies of water, tanks). If ponds are to be built, not all land can be used for ponds. This land should preferably have a high clay content to hold the water efficiently.
2. Water - a reliable source of good quality water is needed ‑ this may be from storage dam, river or bore hole.
3. Food - an inexpensive source of fish feed is a must. This can range from plant growth in a pond to fishmeal products produced on the same farm or bought in as rough or processed feed. Fish meal made from fish flour from low quality fish is used at the moment to feed higher quality fish. With the problem commented above of dwindling fisheries, fish flour has become scarcer and more expensive, facing the aquaculture business with the need to look for alternative sources of proteins for fish feeding. Soy may be another source.
