Commercial fishing for pike
In the aquatic environment, the pike has no equal enemies, and that's exactly what it is, perhaps, it made, that it belongs to the low-skittish fish. With some caution, it is not difficult to get close to the place, in which a predator motionlessly waiting for prey can easily become one. Thus, the oldest fishing tools - walls and barrows - have survived to this day in the hands of poachers, who, especially in early spring, during the pike breeding period, often yet, against categorical prohibitions, they wreak real havoc among them. At that time, spawners were flowing out into the shallows, having completely lost my self-preservation instinct, not only allow you to reach yourself with the blade or stun you, but even put a wire loop on the pole around the torso. Alongside these barbaric methods, rightly branded as vandalism, there is a new threat today, from scuba divers armed with crossbows, for which pike is the most easily achievable goal.
A practical way to implement the economic objectives is fishing conducted not with the intention of acquiring as many fish as possible on an ad hoc basis, but about such regulation of the state of their stock, so that the achieved indicators of the fishing efficiency of the exploited reservoir come close to the limit determined by natural resources of the environment. Catches are made using equipment that varies in design and mode of operation; the ability to use it consists not only in mastering the fishing technique itself, but it also requires a proper assessment of the suitability of each gear type for different fish and current environmental conditions, weather and seasonal.
According to the most general division, there are two main groups of fishing gear: drawn (for example seines and lugs) and positives. Drawn tools may vary in size, type of web material or construction details, but they keep the principle of operation common to all types. On the other hand, there are different types among the fixed tools: trap (students, gauges) grasping (wontony), entangling (drygawice), hooked (cords, pucks). Pike is caught with all the mentioned types of gear, however, its quantitative share in the total weight of fish caught with different types of gear fluctuates significantly.

This is understandable, if you take into account their spatial extent. Drawn tools, especially the seine, operate within almost the entire area of the reservoir, including, coastline picture, pelagic and demersal species zones, whereas, meanwhile, trap tools are associated with their range of operation primarily with the coastal zone - the main habitat of pike.
A common trap tool is a schoolboy, built from a wild game cage, divided into two mosquitoes, to which the entrances lead (throat) so constructed, that the fish getting inside would have the retreat cut off.

The nursery is placed among the plants by attaching the tip (kutla) to a pole driven into the bottom and pull the catch cage this way, to keep the lunatics vertical. In order to increase the range of operation (the tools are connected to the game mother by a vertical wall running perpendicular to the first lunatic or are attached to it with wings extending to the sides.
