Native Fish

Having a pond or water feature in your garden has many benefits. Apart from the aesthetic pleasures, ponds can be cooling, and provide an opportunity for increased biodiversity in your garden.

In Perth, we have many species of frogs. Providing a safe place for them in your garden is vital as the population continues to encroach on their original habitat.

Frogs are particularly sensitive to chemicals and their presence generally indicates a healthy environment. They will do their part in reducing insect pests.

When designing your pond, it is useful to have a small 'bog garden' as part of the plan. Many of our frog species actually need this permanently damp soil to breed successfully. Also think of including plants in and around the pond to provide safe havens and a method of frogs exiting the water.

Having fish in your pond will prevent mosquitoes breeding, but we recommend you carefully think about your choice of fish. Goldfish, Koi and Gambesi are all non-native fish that compete with native species and will eat frog eggs and tadpoles.

When choosing fish for your pond, selecting native species (that have evolved with frogs) helps ensure our amphibious friends can continue to breed.

We stock two types of small native fish which are found naturally around the Perth metropolitan region (or at least used to be!) and throughout the South West of WA. These fish are obtained through licensed breeders.

We do not recommend you 'catch your own' from waterways. Besides being illegal, small fish often thought to be native are usually the aggressive Gambesi (eg. in Lake Leschenaultia). These fish were deliberately released into creeks, rivers, etc. all through WA eighty odd years ago - supposedly to reduce mosquitoes. However they have since been found to be less effective in mosquito control that the native varieties - but unfortunately tend to out breed and out compete the natives.

Introducing fish to your pond

Float bag on water and leave a while for fish to acclimatise to temperature. Introduce a portion of pond water into the bag (about a litre at a time), this also allows the fish to adjust to any difference in pH. The longer the period of time you do this over, the less chance of stressing the fish.

Five or six fish will give you a good breeding group. It is thought having at least two males will prove more successful in breeding.

As far as size of your pond - six fish would be ideal for something about as big as a bathtub.
