ANGFA lend a hand at Long Swamp

Posted on 14. Nov, 2014 by Lauren Veale in Long Swamp Restoration Trial, News
While others may have been losing their money on horse races over the long weekend in November, I had the pleasure of meeting with some passionate members from the Australia New Guinea Fishes Association (ANGFA) and showing them around Long Swamp.
One of the main purposes of the fieldtrip was to trial some control and eradication techniques for the introduced eastern gambusia (Gambusia holbrooki). Since first detected during monitoring in 2012, the abundance of gambusia has increased considerably in Long Swamp, but at present the species is largely confined to one area of wetland. If this species continues to increase in abundance and expand its distribution into re-created aquatic habitat made available through restoration, it has the potential to seriously interfere with the ecology of resident populations of key native fish species in Long Swamp.

Have you ever wondered what happens in the outer suburbs of a large city of 3 million people like Melbourne? Some say not much but that would be very wrong. The outer suburbs, particularly in the population growth corridors, are full of activity and full of life; human, plant and animal. And they even have a threatened little fish.

..... Like the many thousands of visitors before us, the plan was to take in the experience of the crystal clear water and abundant aquatic fauna and flora. Unfortunately this trip was very different to past experience and expectations as we saw the alarming deterioration of the Ewens Ponds wetland and out-flowing Eight Mile Creek. The most noticeable change was the widespread infestation and impact of an aggressive new form of blue-green algae throughout the ponds and creek.

Concerns were raised about the survival of the Lake Wanam rainbow in 1994 - 5 when adventurer Heiko Bleher had noticed significant change in the fish populations of Lake Wanam. Over a period of 3 years Heiko observed large increases in the tilapia population of the lake and a corresponding dwindling of Glossolepis wanamensis. Indeed in 1995 he was only able to collect 2 old male specimens of G wanamensis.
