Last week the Live Exhibits team went into the field in search of eels and other fish to restock the pond in Milarri Garden.

Last year the iconic Short-finned Eels (Anguilla australis) living in Milarri pond were moved to the Forest Gallery water system while we repaired and resealed the pond. Now Milarri pond is back in operation and ready for new inhabitants.

Prior to the Milarri pond works, regular eel feeding sessions were very popular with museum visitors, giving our staff the opportunity to highlight the importance of eels as a traditional food source for local Aboriginal people. In western Victoria, kooyang (eel) were trapped using woven nets in sophisticated aquaculture systems by the Gunditjmara people for thousands of years – one of the featured installations of the upcoming First Peoples exhibition at Bunjilaka Aboriginal Cultural Centre at Melbourne Museum.

We collected the new eels west of Melbourne under permit, and we also caught other fish such as Tupong (Pseudaphritis urvilli), Flathead Gudgeon (Philypnodon grandiceps) and Common Jollytails (Galaxias maculatus) boost stocks in the Forest Gallery creek and pond system. These are just a few of the 50 or so species of freshwater fish found in Victorian waters.

Freshwater invertebrates, particularly Glass Shrimp (Paratya australis) were also collected to kick start the food chain in Milarri pond. Yabbies (Cherax destructor) will soon walk across land from nearby ponds, and many other invertebrate species will fly in or colonise via new plantings or by adhering to waterbirds. Pacific Black Ducks (Anas superciliosa), Little Pied Cormorants (Microcarbo melanoleucos) and other birds will soon arrive under their own power.

At the end of the collection trip, animal keepers Chloe and Dave released the eels into their new home, where they will live under the care of Live Exhibit staff for many years.

Fish destined for the Forest Gallery must be quarantined for three weeks in tanks set up behind the scenes to ensure no parasites or pathogens are introduced to our resident fish population.

A range of fish species as well as Macquarie Turtles (Emydura macquarii) can be seen daily in the Forest Gallery at Melbourne Museum. Silver Perch (Bidyanus bidyanus) and eel feeding presentations will recommence at Milarri pond in September when the water starts to warm and the eels’ appetites return.
Milarri Garden and Milarri Walk are open every day of the year except Christmas Day and Good Friday.
