FLOATING NET CAGE FOR FISH, HOW TO BUILD A KOI CONTAINMENT IN DETAIL, NETTING TUTORIAL,BREEDING CARP


Hi this is Carl the landscape guy. Today I
want to build a large floating net basket, which is going be used in a natural pond.
Therein, larger fish can temporarily be held in quarantine or it can be used for raising
young fish. There are different floating nets available but they are pretty expensive and
they don’t really fit my needs exactly. I will now show the construction step by step
and i will explain what i do. At the end I will test the new floating net basket in a
natural pond. First I am planning exactly how big the keep
net will be and make a drawing. It is going to be 2.2 meters long, 1.2 meters wide and
0,8 meters deep. The drawing can now be used to . This drawing shows the net spread, it
going to be made in one piece, that way I save some seams. I decided to use weatherproof
fishnet mesh type PES300 with 3mm mesh width and ordered 10m² at netzeallerart.de
I designed the net the way that it can be sewn together in cuboid shape. It is easier
to cut the mesh on level ground using the straight joints from the terrace for example.
That way i get the rectangular angles easier. With tape measure, ruler and marker pen, the
cuts are now transferred from the paper drawing onto the mesh. Since the mesh is to be cut
the same way on both ends I fold it once, in order to be able to cut both ends simultaneously.
Slipping can be prevented by fixation with needles. Then the slices are easily carried
out with sharp scissors. Now the net is sewn together according to
the drawing to a cuboid. Polyester sewing thread is used. Sewing works well if it’s
a stiff mesh like this one. The
net is now folded around like this and stitched again, that way they are more durable and
look nice too. It is sewn with tiny stitches because they consume more thread length and
therefore the seams are stretchy. The net remains resilient and the thread doesn’t rip.
The keep net will float on the water through pipes later. Therefore the net is flipped
on the edges and sewn as a wide seam, so the float tube can later be simply inserted into
the so formed tunnel. It is left open at one spot so that the pipe can be inserted.
As floating tubes I use PVC pipes 7,5 cm in diameter. These are stable, have an inconspicuous
color, rubber seals on the connections and I can take it apart at any time again. I use
2m pieces for the long sides and 1m pieces for the short sides. Each corner is built
from two 45° pipe elbows. I bought all pipes at the hardware store. All seals are treated
with lubricant that way they can be pushed in easier and seal off better. The floating
tube ring is left open at one point, so that I can slide on the sewn net. It works best
to have someone helping to hold the pipes while you slide it on. Now it looks quite
like a fish keep net already. But I will add a removable cover net. This
should keep the fish safe from predators like herons and cormorants and keep the fish from
jumping out. For this I use some PVC pipes again. This time I use 87 ° pipe elbows for
the corners. The pipes need to shortened as the lid is going to sit inside the floating
pipes of the net. I cut off about 7 cm and deburr the edge. For a nice mark around you
can use a piece of pipe like this. Now all the pieces are put together.
A net will now be stretched onto this pipe-frame. To secure the net screws are placed in the
pipes. The screws can be set at the crossing points, which gives additional stability.
In between more screws are set centrally. Now the net can easily be put on. It is a
stable Bird netting that is stretched with a threaded string.
I want to put some weight in the inside of the floating net basket to keep it hanging
down. Therefore I got some thin cable pipes and elbows. I stuff some metal wire into the
small pipes to make them heavy and cut them to the right length. Now I am gluing the pipes
together with the elbows to a frame that fits the size of the net basket. I drill small
holes into the pipes for the air to come out under water. Allow to glue to dry and done.
Now the fish keeping net can be set into the water. It now consists of three parts, the
net with float tubes, the cover and the weighting. I put the net in first, then I put in the
weighting. The tube fills up with water and sinks to the bottom, so the net doesn’t wrinkle
and hangs down nicely under water so the fish always have enough room to swim. The cover
net is put on, the screws are mounted so that they cannot damage the white netting.
If you now want to put a fish in, just slide the cover off a little. If you want to take
out fish, just take the hole net out of the water. There is a nice gap between the covering
net and the water surface which makes feeding through the net possible without problems.
Of course you can also use a smaller mesh cover net. The relatively large size tubes
keep everything safely on the surface. Overall i think my new floating net basket is very
convenient, the young fish have plenty of space for swimming, they are protected from
birds and I can feed and watch them while they swim in their usual water. Overall, I
spent about 90 dollars for the materials. I hope that this video was helpful whish you
good luck with your projects. Helpful comments are always appreciated. Take a look at my

  1. This Video has been really helpful. I'm considering to show it to my collegues in a seminar I'm organising. Thank you for this educative compilation. edwin

  2. Is the substance lubricated enough to prevent the ingress of water into the large tube structure so that it stays afloat ?, Do you use hypertext resin to prevent water from Aljul? My question is important because I can dismantle the basket to move them to another location for easy transport.
