To prevent your fish from escaping, and to prevent unwanted fish from entering your ponds, they need to be fitted with an appropriate sized overflow pipe which has an appropriate size screen. That means a screen size that will work efficiently, allowing excess water to exit the pond, without letting your cultured fish escape, or any unwanted fish species entering your pond. This pipe should be positioned correctly to be effective. 

In Australia, many native fish species will swim long distances through running water, even through very shallow water, and grass. Tilapia will also travel long distances in the same way. It is common for tilapia to be in rivers and streams in many countries. Particularly in Asia and north eastern Australia, where they have established themselves in water holes, creeks and rivers. If these fish enter an aquaculture pond they will compete with the species you are trying to grow. They will eat the aquaculture feed you use to grow your commercial crop. They will breed to plague proportions making it difficult to sustain profitability. Tilapia have a very low commercial value, especially compared to more commercial species such as jade perch.

The pipe needs to be large enough to handle the amount of water that will enter the pond during heavy rain. The surface area of the screen should also be large enough to allow all the water to freely flow fast enough to keep up with the heaviest rain. Below pipe is 150mm (6") with 50mm holes.

Drilling large holes, or cutting pieces out of the pipe will give the screen support so it does not collapse during high water flows. This is particularly necessary in the tropics where high rainfall is common.

The pipe should be angled so that the screen is below the water level when it overflows. This is to reduce the chances of the screen becoming blocked with leaf litter and grass. If it is at the surface it will work like a tea strainer and quickly become blocked increasing the risk of the pond overflowing its banks. The screen should also be cleaned regularly to maintain efficiency.

Rodents will also make holes which must be repaired.

The outlet should be above the ground to help reduce the chances of fish entering the pipe and finding their way into the pond, even though it has a screen, baby fish could still enter the pond.

The outlet should be maintained and free of vegitation. Unlike the pictures below. Here the grass has not been kept away from the pipe outlet which will slow the flow of water.
