Approved by the Order of the Minister of Agriculture of the Republic of Kazakhstan of January 19, 2015 No. 18-05/22

Requirements to fish-protecting devices of water intaking constructions

1. To fish-protecting devices of water intaking constructions (further - RZU) establish the following requirements:

1) the effectiveness ratio of RZU shall be at least 70% for juveniles with length of body more than 12 millimeters which is determined according to the calculation of efficiency of RZU given in appendix 1 to these Requirements;

2) RZU depending on settlement expense of water intake are established according to appendix 2 to these Requirements;

3) diameters of cells of the RZU mesh rybozagraditelny screens depending on the sizes of fishes are established according to appendix 3 to these Requirements.

2. Designing of RZU is carried out on the basis of design and survey and scientific research in which are determined:

1) specific and dimensional structure with indication of the minimum size of the protected fishes;

2) period of their slope and migration;

3) vertical and horizontal distribution of fishes;

4) locations of spawning areas and zimovalny holes;

5) the taking-down current speed for juveniles of the protected fishes.

Calculation of efficiency of fish-protecting devices

1. Indicator of fish-protecting efficiency (Kef) is the relation of quantity of the fishes detained by the fish-protecting device to number of the fishes getting to the water intaking construction in the absence of such device expressed as a percentage:

where:

N1 T - quantity of the fishes who got to water intake for settlement period of T in the presence of the fish-protecting device;

N2T - quantity of the fishes who got to water intake for the same settlement period of T in the absence of the fish-protecting device.

2. The indicator of fish-protecting efficiency is determined experimentally - observations of hit of fish in water intake in turn in case of availability and lack of the fish-protecting device.

In case of impossibility to dismantle RZU, Kef it is determined by difference of concentration of fish before RZU and behind it by formula:

where:

C1 - concentration of juveniles of fish for RZU;

C2 - concentration of juveniles of fish before RZU.

3. Efficiency of RZU shall be at least 70% for juveniles of fishes more than 12 mm in size.

4. If the juveniles perish in case of contact with RZU (flat grids, struyereaktivny drums, etc.) and in rybootvoda (if RZU with rybootvody), then the indicator of fish-protecting efficiency is calculated by the following formula:

where:

N1T - quantity of the fishes who got to water intake for settlement period of T in the presence of RZU;

N2T - quantity of the fishes who got to water intake for the same settlement period of T in the absence of RZU;

N3T - quantity of the fishes who died for settlement period T after contact with RZU.

The size N3 is determined by the amount of quantity of the fishes who settled on RZU (n 1) which died after contact with RZU (n 2) and the dead when passing rybootvodny path (n 3): N3 = n1 + n2 + n3.

Works on determination of number of juveniles (N 3) perishing in case of contact with RZU are conducted as follows:

n1 - is determined by the miscalculation of quantities of fishes on the fish-protecting device;

n2 - the number of the juveniles of the fish caught below than RZU in case of the working water intake which died after otsazhivaniye on survival;

n3 - the number of the juveniles of the fish who passed rybootvod which died after otsazhivaniye on survival.
