The fishers will sail out to the lake tomorrow afternoon.
The fishers want to fish using traps for pike and tench in the coastal zone.
In accordance with the provisions of the Act on Inland Fishing, a protection period for pike is in force until 31 May.
Despite the protection period, you can get permission to catch spawners to obtain stocking material.
The fishers will also fish with a Peter net for whitefish and zander in the water column.
In winter, the ice was too thick and they could not fish.
One of fishers was on the course where he/she received a fishing permit for a power generator.
European eel cannot be fished with aggregate, and then be used for stocking.
Zander and pike will be waiting for spawning in the livewell located on the flowing water.

Production of stocking material
Stocking inland waters
Tomorrow I will bring the fish from the stocking centremf830f5f44d042f59_1527664172190_0stocking centre and carry out the stocking of the lakesmf830f5f44d042f59_1527664632098_0stocking of the lakes. - Which lakes will we be stocking and with what species? - We will stock those tanks in which we caught spawners during the spawning season. We will consider stocking as a complement to natural reproduction. This is permanent restockingmf830f5f44d042f59_1527664646233_0permanent restocking. We also use them in fish species that do not have conditions for reproductionmf830f5f44d042f59_1527665248917_0conditions for reproduction. Some reservoirs do not have a coastal zone and are characterised by good food conditions. Such tanks should be treated as a regrowth pond and stocking materialmf830f5f44d042f59_1527665261983_0stocking material should be placed in them. We also stock with species that do not spawn in our waters, e.g. eel. - The anglers will be happy. - Yes, we periodically stockmf830f5f44d042f59_1527665402607_0periodically stock the lakes that are overexploitedmf830f5f44d042f59_1527665551521_0overexploited by anglers in order to restore the overfished species. We stock with endangered speciesmf830f5f44d042f59_1527666073814_0endangered species or introduce new species. - Can you introduce new species of fish to lakes? - Restocking of foreign species is prohibited without obtaining the appropriate permit. Our farm, as authorised for fishingmf830f5f44d042f59_1527666097212_0authorised for fishing, has a permit to stockmf830f5f44d042f59_1527666112699_0permit to stock with new species. Before the stocking, we carry out an accurate identification of the natural conditionsmf830f5f44d042f59_1527666127612_0natural conditions of the lake. The typing of lakesmf830f5f44d042f59_1527666140763_0typing of lakes for stocking makes it easier to divide lakes into fishing types. Every year, we check the population statusmf830f5f44d042f59_1527666155571_0population status of a given species and decide whether to end or continue stocking. Based on the survival rate and the number of fish planned to be harvested from the lake, we calculate the amount of stocking material. When designing stocking, one should remember about fish species, whose common development in one tank does not yield a successful economic results. For example, do not stock the same lake with pike and zander. After stocking, please fill in the stocking protocolmf830f5f44d042f59_1527666174710_0stocking protocol.

Fishing melioration in inland waters
- Please, prepare fishing meliorationmf830f5f44d042f59_1527670252897_0fishing melioration in our lakes this year. - What does melioration consists in? - Fishing meliorations is aimed at improving the conditions of themf830f5f44d042f59_1527670276543_0conditions of the fish habitatmf830f5f44d042f59_1527670276543_0habitat and affects the number of fish in lakes. They also improve the conditions for harvesting fish from lakes. - What treatments should I do? - Begin by fighting the excess of emerged vegetation. It causes overgrowing and mudding of shallower coastal lots and shallowing of lakesmf830f5f44d042f59_1527670327858_0shallowing of lakes. The living conditions of the spawn and the feeding conditionsmf830f5f44d042f59_1527670340042_0feeding conditions for hatching and fry deteriorate. With the compact occurrence of plants, the coastal parts of the lakemf830f5f44d042f59_1527670522989_0coastal parts of the lake become completely inaccessible to fish. In addition, such vegetation is a serious obstacle to the use of appropriate fishing gear. By cutting out the vegetation, we will prevent overgrowing of the shores of the lakemf830f5f44d042f59_1527670828629_0overgrowing of the shores of the lake. We will maintain spawning grounds and feeding grounds in the coastal zone. We will also obtain places for inserting fishing equipment and fishing using net tools. At the lake, we will build small ponds for natural fish spawning. We will spawn several species. We will start with a pike, then a zander and a bream, and finally we will spawn the tench. You just have to make sure that the ponds have a direct outflow of water to the lake. Hatched fish will flow to the lake freely. For those fish that spawn themselves in our lakes, we will prepare artificial spawning groundsmf830f5f44d042f59_1527671001554_0artificial spawning grounds. We will make egg collectorsmf830f5f44d042f59_1527671133114_0egg collectors at the bottom and suspended spawning groundsmf830f5f44d042f59_1527671147374_0suspended spawning grounds. We will prepare egg collectors from plant bedding and coniferous branches. Please make the suspended spawning grounds from the branches of spruce and wicker. We can make floating spawning groundsmf830f5f44d042f59_1527671786391_0floating spawning grounds. By creating additional and appropriate substrates for natural spawning, we will increase fish reproduction and thus increase the yield of the lakemf830f5f44d042f59_1527671804687_0yield of the lake.
