Tech.s to clear up fishnets entangled on a Wreck

Can definitely relate to the by-catch aspect.. must be one of the saddest sights to see.. fish, turtles etc trapped in lost nets, fish pots etc.

BTW ..if the wreck is fished regularly...watch out for hooks and monofiliment snagged in the net.. could be hiden under algae growth until you grab it with fingers... ouch!! Real snagging risk too. Again the knife is useless, slashers / shears essential..and placed where you can easily reach them (which is not generally the calf!!)

Indeed, what happens as a result of ghost nets, is really shameful, and i don´t know why, most people disregard it, or neglect it. Maybe their attitude changes if they get accidently stuck on one..

Just last year a Baskings Shark got accidently caught, and killed, a 7meter.

Hooks are present, yes that´s true; got one stuck on a finger, really stuck and was taken out by pull by a friendly fishermen.. no irony, either that or hospital.
So be attentive to that aspect too, sometimes their there just hidden by algae or debris.
In this case those basic leather gloves used for hard work, instead of diving are more apropriate since they besides hard, they get adjusted to the hands once wet.

Doubt the fishermen are happy either when their expensive nets snag on a wreck and they lose them. Not a lot they can do about it. Saw remains of a turtle caught in an old net once, and a shark or two. They sure keep on killing for years

This might be a silly ide but I do enjoy a bit of lateral thinking.

Has anyone ever tried using a flame to cut man-made fibre nets and ropes ?
It would require some specialised kit but might be a quick, low effort way of cutting a large net into managable pieces.

On another note. Lost lobster pots are a feature of British wrecks. I usually try to make sure there is an escape route for any ghost catch.

Not so much of "Out of the Frying Pan into the Fire" as "Out of the Lobster Pot into the Boiling Pot"!

You will still be in the s%^t with the local fishermen ..as ALL lobsters belong to them dont you know?

Hi maayanh:

We have old and new pieces mixed all together; it will be quite a lot of work, for a few months!..
Anyway we got a pretty got number of divers split in 3 ind/team to work on specific spots.
Probably 4/team would be safer; 2 working, 2 monitoring in turns.

(hell as in a lot of work, hopefully!!)

hey aquatiker,

for more relevant responses, please tell us more about the wreck,

some of the things that would give better ability to answer: depth, water temp, visibility, age of wreck, state of nets, available surface support, equipment (OC, CC) etc...

for example the decision whether in a 4 person team whether 2,3, or four people work simultaneously is very dependent on the conditions.
The extreme example is a 'clean up' dive we made on a net caught on a reef (several days earlier - very new) in 20 fsw on a day which had 50 ft vis, 4 man team all 4 working in a geometry which made sure that each diver could see two team mates at all time. The downside of this technique that every time one diver gets caught two divers have to tie-off their work and help/supervise releasing the caught diver.

releasing half dead fish from a net is not usually to much fun.
I remenmer one dive we had to stop work for ten minutes cos' of 4 squid that kept releasing 'ink' into the water as we tried to release them.
and another dive when a diver tried taking a not dead yet fish

home, and lost the tip of his finger..

We normally just bag up the whole fish trap up and enjoy fresh susi as well as bringing up oysters and tucking into fried oysters...we are so refined

Hi, hum... that info has restricted access...have to get clearance from the team leader...so i won´t give out the coordinates

Well the wreck is in a bit of a sloppy area, starting around 30msw and the 2nd segment goes a bit over 40. 2 parts separated by a 7meters.

We´ll have CCR and Nitrox.

Water, well weather dependent, usually 2-4 meters viz.

Water Temp: 12-14ºC

Nets Age: Mixed, old and new.

The ship is down there prior to WW I , cargo transport vessel.

Either 1 or 2 of the divers will be on the look out while 2 are working.
This won´t be changed if the viz get´s better or worst. 1 (or..2) is resting and mostly supervising.

I have practiced fishnets removal from reef many times for (you could say) private reasons. Fishermen in North Greece are so despair that prefer to lose their equipment in sallow reefs. They often destroy my macro photography underwater 'studios'. So I get pissed off and complete 3days projects to remove them. My methods are closer to maayanh but take longer since I do not have a whole group of divers.
By a strange coincidence, these days I was asked to undertake this job for a amateur fisherman who wants to clear his 'treasure' fishing mark (covered with net that of course reduced fishies). It is impressive how much money people are willing to pay for their hobbies.
(god, who is talking)

It is obviously a very demanding task as far as safety procs is concerned and it should never be underestimated condidering depth and visiblity.
