7. The following requirements are established during the operation of FPD of escape facilities:
1) the speed of water approaching to the FPD should not exceed the blowing speed for juvenile fish resources and other aquatic animals;
2) FPD should not impede the passage of water, while being protected from the effects of snags and ice formation.
8. Designing of the FPD is carried out on the basis of scientific research and design and survey work, which defines:
1) species and size composition indicating the minimum size of protected fish resources and other aquatic animals;
2) the period of their concentration and migration;
3) vertical and horizontal distribution and concentration of fish resources and other aquatic animals;
4) the location of spawning grounds, wintering pits, fodder sites and areas of active downstream migration of juvenile fish resources and other aquatic animals;
5) the blowing speed of the flow for the protected juvenile fish resources and other aquatic animals.
9. When using the fixed networks and gratings, the following requirements are established:
1) cell sizes, flow rate, clogging and the possibility of cleaning, conditions of navigation are taken into account;
2) are installed in both pools of hydroelectric facilities to block the approach of fish resources and other aquatic animals to undesirable places and their directing to the inlets of fish passage facilities;
3) the network is made of galvanized wire or kapron and is hanged on floats or on pile supports;
4) the gratings are made of metal rods, the gaps between the rods are taken depending on the purpose of the gratings and the size of fish resources and other aquatic animals.
10. When using electric layers, the following requirements are established:
1) the length of the electrodes located in the layer section is set depending on the depth of the water, taking into account the fact that the electrodes do not reach the bottom of the reservoir and its surface by 0.1-0.3 meters;
2) the effective value of the electric field strength and the distance between the electrodes are set in accordance with the sizes of fish resources and other aquatic animals;
3) the electrode system must be freely hanging (hung on a cable, mounted on floats or fixed on piles), to ensure a more stable vertical position, the lower part of the pipes is filled with concrete;
4) a pulsed alternating current with a pulse duration and pause in the range of 0.02-0.35 seconds is provided.
11. Excluded by the Order of the Minister of Agriculture of the Republic of Kazakhstan dated 18.09.2025 № 307 (effective ten calendar days after the date of its first official publication).12. Water intake from the sea is allowed only if the water intake facilities of the FPD are equipped with the technical devices for continuous monitoring of the efficiency of the FPD in accordance with paragraphs 6) and 7) of Article 273 of the Environmental Code of the Republic of Kazakhstan.

Paragraph 12 is amended by the Order of the Minister of Agriculture of the Republic of Kazakhstan dated 18.09.2025 № 307 (effective ten calendar days after the date of its first official publication).| Appendix 1 to the Requirements for fish protection devices of water intake and escape facilities |
Calculation of effectiveness of fish protection devices
1. The indicator of fish protection efficiency (Kef) is the ratio of the amount of fish resources and other aquatic animals held by the fish protection device (hereinafter - FPD) to the amount of fish resources and other aquatic animals falling into the water intake and escape (pass) facility in the absence of such a device, expressed as a percentage:
Kef = (N2T - N1T) / (N2T) x 100,
where:
N1T - the amount of fish resources and other aquatic animals that have fallen into the water intake and discharge (pass) for the estimated period T in the presence of a FPD;
N2T - the amount of fish resources and other aquatic animals that got into the water intake and discharge (pass) for the same estimated period T in the absence of FPD.
2. The indicator of fish protection efficiency is determined experimentally - by observing the ingress of fish resources and other aquatic animals into the water intake and discharge (pass), alternately in the presence and absence of FPD.
In case of impossibility to dismantle FPD, Kef is determined by the difference in the concentration of fish resources and other aquatic animals in front of the FPD and behind it according to the formula:
Kef = (C2 - C1) / C2 x 100,
where:
C1 - the concentration of juvenile fish resources and other aquatic animals behind the FPD;
C2 – the concentration of juvenile fish resources and other aquatic animals in front of the FPD.
3. The effectiveness of FPD for juvenile fish resources and other aquatic animals larger than 12 millimeter is:
not less than 70% for water intake facilities;
not less than 60% for escape facilities.
4. If the juvenile dies in contact with the FPD (flat nets, jet reactive cylinders) and in the fish outlet (if the FPD with a fish outlet), the fish protection efficiency indicator is calculated by the following formula:
Kef = (N2T - (N1T + N3T)) / N2T x 100,
where:
N1T is the amount of fish resources and other aquatic animals that got into the water intake and discharge during the estimated period T in the presence of the FPD;
N2T is the amount of fish resources and other aquatic animals that have fallen into the water intake and discharge for the same estimated period T in the absence of the FPD;
N3T is the amount of fish resources and other aquatic animals that died during the estimated period T after contact with the FPD.
The value of N3 is determined by the sum of the amount of fish resources and other aquatic animals settled on the FPD (n1), killed after contact with the FPD (n2) and killed during passage of the fish outlet branch (n3): N3 = n1 + n2 + n3.
The work to determine the amount of juveniles (N3) that die when contacting with FPD is carried out as follows:
n1 - is determined by calculating the quantities of fish resources and other aquatic animals on FPD;
n2 is the amount of juvenile fish resources and other aquatic animals that died after being separated for survival, caught below the FPD when the water intake and discharge were working;
n3 - the amount of dead juvenile fish resources and other aquatic animals after being separated for survival that underwent fish outlet.
