Hi Everyone ;-), I've been following this thread and now I would like to share some experience and images with you all, about some of the places where we, some of the ones that live on parallel 49 on the other side of the Atlantic Ocean, collect NSW as well as the equipment used, which as been improving so far...
I've using NSW for some time now and every now and then I collect live plankton of which I will also post here some photographs. When I started some 21 year ago, the use of NSW was done but people would go collect it of shore which I couldn't and at that time pollution was a serious issue since there was no facilities or very few to treat domestic and industrial effluents, the people awareness was not as it is today, no recycling concerns or very few...well ever since things have changed and improved and now it is regarded safe...although, i must say, the risk of bringing
Godzilla home still exists but I/we regard it as a controlled risk, a bit like the risk of bringing home acropora or motipora bugs, or a bacteria that makes way to to cause problems, even with quarantine...
Many of us store the water for a month or so in closed containers placed in a fresh and unlit area, this helps control whatever bad could come in it (Godzilla included;-). So far the reports of incidents are basically due to overfed systems in which NSW with possibly some flat worms is put and these finding a nutrient rich water column, simply develop significantly.
Here you can see one of the places where NSW can be collected and also one of the places were I collect natural sponge to feed the spongivore fishes. The pace is Valadares sul (=Valadares south beach). Its a place where I spent many weekends of my childhood as my family had a house close to the beach. The video was done at the end of the afternoon and the tide was almost low. You can see afloat
Saccorhiza polyschides that you can see bellow completely out of water during the low tide period as well as some other algae and animals found in the intertidal zone.
Laminaria,
Saccorhiza polyschides, almost out of the water
Hymeniacidon sanguinea orange sponge out of the water and moisty
Codium tomentosum - mostly liked by Zebrasomas
Codium tomentosum out of the water along with
Ulva rigida (green algae - very much liked by Tangs) and mussels
Mytilus galloprovincialis.
Chondria coerulescens - "jewel of the jewels" this dazzling vivid blue algae of our cost never cease to impress me.
Anemonia sulcata - "the crown of rubis" of our cost. This beautiful anemone of our cost is very aggressive.
Anemonia sulcata,
Bunodactis verrucosa (closed),
Lythophyllum incrustans (coraline encrusting algae, "jewel" of our coast
Aplysia depilans - Vinagreira do mar - Sea hare similar to
Aplysia californica, which when disturbed releases a crimson substance whose composition is believed to be very oxidizing as it is similar to Hydrogen Peroxide
Bellow you can see some friends of mine getting water by the first method which for obvious:Yikes::tired: reasons has been abandoned for the most part and replaced by a "motorized method":approve:
Given the hard work involved, everyone interested gave some money and we bought a motorized pump.
Bellow you can see some friends of mine at the "official inauguration" of the motorized equipment to pump sea water, little over one year ago. Also this is one of the rocky beaches where I collect natural sponge
Preparation of the equipment
Carlos Mota, wearing the Nike shirt, the person that had the original idea and whose tank is maintained only with NSW
For logistics improvement we found another location partly suggested by me and now this is where it happens

Well this is how we collect presently natural sea water at the Gaia beaches. Our friends from the city of Aveiro have now started to do the same thing but with a more portable pump powered by a 12V connection and transformer
Paulo Marinheiro on the left, an architect friend of mine whose tank you will see below
here you can see two tanks of two friends of mine maintained only with natural sea water (just see the pictures)

Well I'm now buying one of these 12V pumps for pumping diesel, petrol, or salt waters and will collect the water more easily.
We have more examples throughout the country.
If you like to see more photographs of some of the places where I collect sponge, water, as well as some other photographs sent for the same purpose by other members, well have a look here
