The mist-net was invented in Japan by hunters around the century XVI (1680?), as a technique to capture birds for food. Since there it was first used to research bats in United States at the third decade of century XX (Poole, 1932). Actually the Goverment of Japan has high restrictions to sell mist-nets, requesting to be just to research. Unfortunately other countries are producing or selling mist-nets without restrictions to customers.
In a few of countries a permit to use mist-nets is required, as Canada, Costa Rica, Japan and United States (write us to notify us more countries).
Since their develope, the mist-nets have been modified to get a better performance. Actually is used by ornithologist and bat biologist to capture birds and bats, in banding and research projects, and is necessary to be used by trained personnel.
The mist-net looks like a fragile fish net made of 3 to 12 meters long and the most common high from 2.6 to 3 meters. They are made of nylon monofilament or multifilament. There are also mist-nets made from polyester or dho-gaza, this last one for birds as raptors. The very best nylon is produced in Japan. Actually mist nets are produced in China, Japan, Polony and Unitated States. The best ones: Japanese Mist Nets, the original.
There are different characteristics in a mist-net:
The mist-nets usually are made with 4 or 5 shelf. The shelf is the important part of the mist-net because is the baggy area where animals are captured.
Is the opening defined as the measure of two sides of the square or mesh. A mist net with a side of 15mm would be a mesh 30. You may find mist-nets with a mesh from 24 to 121.
It is a term used in the textile industry. It is defined as the weight in grams of 9000 meters of the yarn. For example a denier of 70 means that 9000 meters weight 70 grams. The lower the denier, more fragile is the mist-net, but less visible to the animals. You may find mist-nets with a denier from 50 to 210.
It is the number of strands of a yarn used to make a net. The denier refers to each strand of a yarn. Usually the mist-nets are made of two strands named multifilament. A mist-net with Ply/Denier 2/70 is made with two strands each one of 70 Denier.
