Default Oyster Dredge

So, some of you know I'm a shop teacher.

One of my projects this year has been building an oyster dredge with a few of my kids for a Marine Science and Technology class that I teach.

We work closely with our local shellfish comission, some of you may have seen the 20' Scow we built. The last 2 seasons we have been dredging a little on local oyster beds to see what comes up with an old dredge someone gave us. We rebuilt it but also copied it to make another one.

I am at the point where I need to buy some netting and chain male or chain netting for the bottom? Where can I get this stuff and what is the correct terminology. I'm a total novice at this and doing it more for the experience of the kids. Any pointers greatly appreciated.

Some pics....

The old dredge.

The new dredge in need of parts. Please let me know if you guys with experiece see something wrong. Going to be towed behind our scow.

The "claws" on the bottom will definitely be made shorter.

I don't have much info that you are looking for but it seems that programs you are involved in really are great. Real life hands on projects always seem to get People involved. I'm sure the kids love it.

You can get the rings(scallop rings) and open links(scallop links) to connect them from one of the supply houses in New Bedford in fact i'd bet if you gave them the measurements of the chain mat they could make it up for you and even attach the twine top to it. The reason i'm saying to have it made up is the link closer is a expensive tool to buy for such a small job. Maybe check with Wilcox they are a bit closer to you.

You also might think about attaching a length of rope with a small buoy on it to the "club" on the back of the bag that way if you get the dredge hung down on a snag you could pull it free from the back end.

Steve is on it.....The "clubstick" is the wooden piece attached to the bag. Want to make sure that is not broken or bent for the dredge to fish right.

BTW, your twine top is "hung" cross twine. That means the knots are pulling sideways. It should be turned 90 deg from what you have. You also may want to try to find out what your hanging "ratio" is. i.e. what size piece of twine to cut.

2:1 means the meshes are twice as long as wide. So if you buy 4" twine (stretched mesh measured so the side knots touch) that means you seize a mesh every 2" across the top.

Instead of the cutlinks to hold the rings together you could use s links and use a pliers to close them

Thanks for the info guys, keep it comming.

As you can see, we cobbled the old dredge back together with zip ties and chain links.

The "club" was broke, so we made that one from a 2x4.

I have plenty of man power, (students) so my plan is to make the lower chain net out of open links from chain we have on hand. Any suggestion how we can make the netting cheaply or sustitute something? This is a public school, so funding is a little tight (non-existant).

Anywhere local to me that I can get an old trawl net? Does that stuff get thrown out or is it mended? I would think a square yard would do it.

Thanks!!

alot of our twine tops here are hand tied. a spool of heavy twine , a large net needle and go for it. we tie long top meshes and get smaller as we get closer to the chain bag. tends to let some empty shell out the top of the bag and it is eaiser to dump.
