Marine Pests Dpi Booklet - Nsw

[arpie]

Hi all

A while back, I found a strange weed in Wallis Lake, so reported to our local DPI office. As a result of this, they gave me a laminated copy of the Marine Pests Booklet shown below.

It also shows how 'not to' spread any weeds/pests from one area to another by careful cleaning of boats & yaks before moving from one waterway to another. Didymo/'Snot Weed' is a prime example of how large areas of the South Island of NZ has been affected by the movement of this horrible pest from one stream/river to another - turning pristine trout fishing streams into waste lands.

Well worth checking out, even printing off & keeping in your boat.

Some of the pests are remarkably similar to other native species, so it also shows other similar native marine growth or animals to avoid confusion

Interestingly enough, today, whilst paddling in The Keys, I came upon a type of jelly fish that I have never seen before ....... it is white, lives in shallow water, sits on the bottom (instead of floating) and looks like the top of a cauliflower, if sliced off! Most unusual, so I contacted Martin of the local DPI/Fisheries office.

From my description, he didn't recognize the species. A local paddler who knows the area well had also not seen it before, so I was amazed it is in the numbers that it is in the creek! It is the only spot I have seen it in so far!

I had actually netted a specimen to give to them, but, 2-3hrs later, it wasn't in the best shape, having gone brown & almost 'liquid' since being removed from the water & I had biffed it! So, hopefully, this week, Martin & his team will be able to gather some & keep them in better condition than I did & identify whether they are an introduced species or not!!

Hi all

Just had a phone call from Martin of DPI regarding the jelly fish I found at The Keys in mid July - it is called the Upside Down Jelly Fish & is normally found in more tropical climates. He had submitted it to the Bio Security people who were not concerned that it had been found in Wallis Lake & have now noted that it has established itself here. So far, I have only seen it in the one creek that backs onto a caravan park, where people would put their boats in to access the lake. I can only guess that a northern tourist may have had one or part of one on their outboard & transferred it to the creek, where it has thrived!

Upside Down Jelly Fish (looking like the top of a cauliflower!)

I will keep an eye out whilst paddling to see if they invade other areas of the lake & let DPI know if they do!

He thanked me for advising them of it & has asked me to keep an eye out for any other unusual critters in the lake!
