Fish Care

Murray Cod fingerlings - damWater

Comprehensive water tests are expensive and are generally not needed for farm dams.  Most surface and bore waters suitable for irrigation or stock are acceptable for fish.  Simply stock a few fish and see how they go.  Muddy water may not harm native fish directly but it can lower food production by obscuring light.  However it can help reduce predation by making the fish hard to see.

Stock Rates

The carrying capacity of a dam (i.e. the maximum weight of fish it can support) depends on the amount of food produced, size of the dam, water quality, species of fish and other factor.  Carrying capacity is generally independent of water depth, as food is usually produced (the food chain) in the water near the surface.  The stocking rate is therefore calculated from surface area alone, ignoring depth and volume.  The number of steps around the dam (the perimeter) is the number of fish to stock.

Releasing Fish

When releasing fish, sit the bag in the dam water for 10 minutes to let the temperature adjust.  Then open the bag and let in small amounts of dam water over 20 minutes, so that there is no sudden change in temperature or water chemistry.  If possible liberate the fish near cover.

Food

The natural food for fish in farm dams is plankton, tadpoles, insects, yabbies, mud eyes and shrimp.  Supplementary feeding with artificial food is not recommended.  Fish tend not to eat the extra food, which can decay and pollute the water, resulting in poor water quality, disease and excessive plant and algal growth.
