Please find attached a fish survey report from Streamline Research. The survey was kindly funded by Australian Unity Healthcare Property Trust (owner of the Beleura Private Hospital – refer attached press release for background).
My take on the key outcomes are as follows:
1. Good News: despite our concerns about on-going erosion and siltation impacts on Tanti Creek (refer to original press release), we have not lost any of the previously recorded species. Streamline Research concluded that anecdotal evidence of diminishing fish populations is most likely due to limited “invitation” flows of water during the past couple of spring migratory periods (all the recorded native species are migratory and need higher flows of water to get upstream from the bay past in-stream barriers).
Take Out: If “invitation” flows are becoming more erratic we may need to remove some of the remaining in-stream barriers so fish can migrate during smaller rain events. It may be no coincidence that the school of young Common Galaxia caught at Marchington bridge was immediately downstream of a barrier.
2. Not So Good News: a feral fish species – Eastern gambusia – was recorded in Tanti Creek for the first time. Gambusia was introduced to Australia in 1925 to control mosquitoes. But they are aggressive predators, prolific breeders and have a high tolerance for poor water quality. There are minimal effective control options. The best approach is to ensure a healthy creek habitat so native fish can be more resilient against the impacts of Gambusia.
Take-out: Peninsula residents must ensure no alien fish are released into local waterways
3. Bad News: Streamline Research elected not to sample one site (in the headwaters of the creek) due to water contamination (refer to photo in report). The pollution was coming from the Tanti Creek stormwater pipe that drains water from the light industrial/commercial area between Watts Rd and the Mornington-Tyabb Rd.
Take-out: households and businesses must take all precautions to ensure polluted water does not enter our stormwater system. Streamline Research advised that one bad pollution event can wipe out the entire fish population in a creek.
I’ve also attached a copy of a brochure on Eastern Gambusia for your information.
Now when you see a fish in the creek you will be able to identify it! A tip: the Eastern Gambusia often hang around at the surface looking like tadpoles!

Mornington Environment Association (MEA) is looking to expand our activities to include BeachPatrol3931.
We are asking for volunteers to join us ONCE A MONTH for approximately 1-2 hours to help keep our beaches clean. Postcode 3931 includes Fisherman’s Beach, Mother’s Beach, Shire Hall Beach and Mills Beach. T-shirts and cleaning equipment will be provided.
For those of you that care about the environment and the community area you live in please help us set this project up.

Following the Meeting of Environment Ministers on 28th July 2017, we failed to see a national-scale announcement of a ban on lightweight bags, as NSW blocked any advance. But we are still moving forwards.
There was some state progress and we know that Victoria and Western Australia are still considering a ban and working towards new policies. Of course major retailers have also committed to phase out the bag, but this won’t cover all outlets, still leaving millions of bags polluting the environment. The National Retailers Association supported the call for state laws to cover all stores – so it’s now up to the politicians.
To continue the fight for our oceans we are asking you to send an email to your local MP asking them to increase the pressure on their Premier in WA, NSW and Victoria to introduce legislation to protect our oceans.
All you have to do is type in your postcode and your details and the form will automatically update the template – or feel free to add your own personal touch to your letter.
Help introduce solutions to plastic pollution by sending an email to your local MP.
There really is no excuse for inaction. It’s well and truly time to #BanTheBag across Australia once and for all!
Thank you for all that you do,
Jeff Angel and the Boomerang Alliance Team.
