Crayfish are divided into broad-toed and narrow-toed. Both species are similar in their biology. The habitats of broad-toed and narrow-toed crayfish do not overlap, that is, they do not live together. Narrow-toed crayfish, once in a pond, completely displace broad-toed from it. Crayfish catching will be successful if you know the places of their possible habitat.
Cancer does not like stagnant, muddy water, shallow water with a hard sandy bottom, ponds with muddy and densely overgrown with algae. In such places, hunting for crayfish is usually useless. Cancer lives in rivers and flowing lakes with dense soils suitable for the construction of burrows and with a high content of oxygen and mineral salts in the water. Crayfish live at different depths from 0.5 to 3 meters. Crayfish live apart, each in his refuge.
Crayfish prefer a rocky, rugged bottom, in which there are many diverse natural shelters. If the bottom is clay, flat, without stones and other shelters, then the cancer digs a hole in it. If the coast is steep, steep, then the cancer digs a hole in the wall of the coast, below the minimum water level. Cancers are omnivores. Although they prefer plant food, they also eat small bottom animals, mollusks, insect larvae, worms, dead fish, etc..
In the daytime, the cancer, as a rule, sits in its shelter and guards it, blocking the entrance with its claws. When danger approaches, the cancer immediately goes into the depths of its hole, trying to hide as far as possible. At night, or in rainy, cloudy weather, the cancer leaves its shelter in search of food and moves along the bottom of the reservoir. Sometimes, in some reservoirs, crayfish can go hunting in the early morning, in the wee hours. In winter, crayfish go deep and sit in their burrows.
Crayfish catch by hand, day, night, at the bottom, in holes.
Catching crayfish with your hands is the easiest and most effective way. You can catch day and night. But the best time is at night, a couple of hours after sunset. At this time, the crayfish are very active and crawl out onto the shallows themselves. Sometimes on land. You can attract crayfish to the shore with the help of light (bonfire, torch, lantern) and bait flooded in shallow water. During the day, crayfish need to be searched in their burrows, under snags, stones, in the folds of the bottom topography.
When searching for crayfish under stones or snags, it is important to remember that cancer has a very good response to danger and swims backwards very quickly with the help of its tail. Therefore, when lifting or turning over a pitfall, the cancer can easily escape in the muddy water. In this case, it is more convenient to catch crayfish together, one raises stones, and the other catches prey.
To catch crayfish in holes is much easier. The rhine hole has the shape of a tunnel. The depth of the hole can reach a meter or more. The inlet to the hole strictly corresponds to the dimensions of its owner. If the cancer is large, then a person’s hand enters it almost freely until the dead end. Scratches are possible when grabbing a cancer claw with your fingers. Therefore, to avoid infection, the hand must be protected in advance with any cloth, bandage or gloves..
Tie a fishing line or thread to a strong branch (rod). Tie a small load (pebble) to the free end of the fishing line and bait a frog, a small fish or a piece of dead, stolen fish, a piece of any meat. It is better to wrap the bait and the load with a mesh cloth (nylon stocking, bandage). By lowering the bait vertically to the bottom near the shore, you can hold the rod in your hand, or you can stick it into the ground. When the fishing line begins to move slightly or the fishing rod in the hands begins to twitch slightly, then the cancer grabbed the bait.
It is necessary to raise production from the bottom smoothly and carefully. If you have to fish away from the coast, at a greater depth, then you need to attach a float (a piece of dry branch, polystyrene) to the length of the fishing line (thread). The distance between the bobber and the cargo with bait is equal to the depth of the place of fishing. Bite can be determined by the float. But it’s better to periodically pull the tackle ashore and check it.
A crayfish harbor is a long, sturdy stick with a fork in the cut branches at the end. Or a stick split from one end so that it turns out a fork. Insert a pebble or piece of branch into the cleft. Catching crayfish on a jail is most convenient at night. To make a bright bonfire on the shore or to light a fishing spot with a lantern. Near the shore, in shallow water, where the water is most transparent, scatter the bait along the bottom.
If the bait itself does not sink, then attach a load to it, a stone can be pushed into the mouth of a dead frog or fish. Keep quiet. After waiting for the crayfish to reach the sandbank, carefully, silently, press the prey with a fork of a stick to the bottom. Cancer, as a rule, gets stuck in a fork (splinter). With his free hand, remove it from the water.
Simple rakolovka is a sinking frame, covered with any mesh. The frame can be of any shape, round, ellipse, rectangular, square. The material for making the frame is better metal, thick wire. But you can make a frame from a flexible branch, bending and tying its ends. Instead of a net, you can twist the frame with thin branches of willow so that the cancer could not jump out. Or any other branches, stems of climbing plants, long grass, rope, strips of fabric, wire.
Secure the load in the center of the rakolovki. Tie a rope to the frame so that the rakolovka can be lifted up without turning it over. Instead of a rope, for pulling out of the water, you can fasten a vertical, long, not thick, point-pointed stick in the center of the rakolovka like an umbrella so that the entire device can be reliably lifted up from the bottom of the reservoir, overcoming the natural resistance of water and cargo.
From the bottom of the pointed stick, tie a strong cross. Then, attach the frame to the crosspiece. The frame is twisted or fixed on it. The pointed end of the stick is needed to stick into the bottom soil of the reservoir and fix the entire rakolovka in one place. The bait should be located in the center of the rakolovka. It is advisable to check the pattern several times per hour..
