"Things You Wouldn't Know If We Didn't Blog Intermittently."
You read Estonian? You surprise and delight every time! I'll go back and see if I can opt for translate.
Ahhh... no. I originally saw the image elsewhere and saved the photo, read the caption there, but then lost the link, so I couldn't credit the source, but I needed to credit the photographer, so I reverse-searched the image and found the Estonian site to give them a "via."
maybe they do the heavy lifting? Like pulling a drag net over the seabed, or closing the loop line on a big net.
perhaps like tubes made of netting? As pulled along, fish go in “mouth” of net...but other end is closed?
I'll guess that these are just nets. they happen to be photographed with their open ends raised. The fish are at the bottom, still alive because the bottom is in the water.
So you and Aaron are suggesting they are funnel-trap nets rather than sieve nets. Could be. I hadn't thought of it that way.
I was hoping you wouldn't notice how wrong I was! I honestly thought this was a work of art made from nets--only upon later review did I actually see the fisherman! It would appear that the nets would not at all work as funnel-trap nets, since, the angle of the nets makes it seemingly clear that this is not being used that way. Thanks for being gentle with me! Love this site, by the way--and especially Divertimentos!
a little bit of googling brought up stuff like this, so it's even possible that the nets don't do anything but look good: http://www.chinadaily.com.cn/a/201712/16/WS5a3491b2a3108bc8c673507a.html or http://www.xinhuanet.com/english/2016-12/08/c_135890887.htm
Doesn't look like I can edit my comments. There is actually a set of fotos, this is another one: http://yourshot.nationalgeographic.com/photos/10534830/ Based on that, and the other fotos I saw from that region, I would assume the tidal range there is big enough for these to be fully submerged at high tide, or the openings can be lowered by some kind of pulley system.
The National Geographic link you found does give some location information: "Fisherman at work while the wind blows up the nets on the river in Xiapu county, Fujian province, China." Thanks, Matthias.
And an article in the Singapore Straits Times suggests that what the photo shows is not a net for trapping fish, but a ?canvas device for harvesting laver (seaweed} "During harvest, farmers dry the kelp on nets strung up on bamboo poles embedded in the mud."http://www.straitstimes.com/multimedia/photos/the-art-of-seaweed-farming
