Understanding, enjoying and caring for our oceans
In The Advertiser this week, the CEO of Clean Seas, Rob Gratton, claimed that if yellowtail kingfish farming returns to Fitzgerald Bay, upstream of the Point Lowly giant cuttlefish aggregation in Upper Spencer Gulf, it “will be subject to some of the most intense ongoing monitoring you can imagine”.

If you’ve been following the news in South Australia over the past few months, you’re probably aware of the many hectares of dead, dying and distressed vegetation in the St Kilda salt marshes. The most recognisable of these is the iconic grey mangrove, Avicennia marina, which can be seen up […]
Port Playford – the latest in a decade of industrial proposals for Spencer Gulf by Dan Monceaux Most naturalists probably haven’t committed much thought to the topics of port developments, seawater desalination, shipping and their respective environmental impacts. I found my way into these fields of study back in 2011, […]

The Marine Life Society of SA was recently asked which species of sea slugs (which include nudibranchs) are found in the Port (Adelaide) River. We’ve only just started exploring the river underwater, so the list below is very much a work in progress. Prior to 2017, as far as we […]
Divers and snorkelers often come across discarded or entangled fishing gear underwater. Unsurprisingly, the problem is most pronounced around rocky points or jetty structures where people regularly fish. Responsible divers do the right thing, and where practical, cut loose and bring ashore any gear they encounter… though one must be […]
I was first inspired to pay more attention to this often overlooked ecosystem by the discovery of the upside-down jellyfish, Cassiopea sp. there in 2016 by MLSSA president and area resident, Steve Reynolds.
