Abstract
Способ определения общего допустимого улова рыбы, включающий облов исследуемого водоема с последующим определением численности, ихтиомассы, возрастных и размерно-весовых показателей выловленных рыб, отличающийся тем, что осуществляют облов исследуемого водоема габаритным мелкоячейным неводом с коэффициентом вылова не более 0,2 при селективном и не более 0,3-0,4 при неселективном промысле, определяют прирост ихтиомассы выживших рыб в возрастных и размерно-весовых классах и популяции в целом за год, а также коэффициенты восстановления ихтиомассы выживших рыб в возрастных и размерно-весовых классах и популяции в целом с последующим расчетом общего допустимого улова (рыбы) следующим образом:В-Y=Ву; Bу·ΔР/В=Ру; Bу+Ру=В,где В - исходная ихтиомасса рыбы отдельных возрастных классов или всей популяции в целом, кг/га;Y - общий допустимый улов рыбы отдельных возрастных классов или всей популяции в целом, кг/га;Bу - оставшаяся ихтиомасса отдельных возрастных классов или всей популяции в целом, кг/га;где ΔР - прирост ихтиомассы выживших рыб отдельных возрастных классов или всей популяции в целом, кг/га;ΔР/В - коэффициент восстановления ихтиомассы отдельных возрастных классов или всей популяции в целом;Ру - прирост, создаваемый оставшейся ихтиомассой отдельных возрастных классов или всей популяции в целом (Bу), кг/га.A method for determining the total allowable catch of fish, including the catch of the studied reservoir with subsequent determination of the abundance, ichthyomass, age and size-weight indicators of the caught fish, characterized in that the survey of the reservoir is carried out with an overall small-net seine with a catch coefficient of not more than 0.2 for selective and not more than 0.3-0.4 in non-selective fishing, determine the increase in ichthyomass of surviving fish in the age and size-weight classes and the population as a whole over the year, as well as the recovery coefficients omassy surviving fish in the age and size and weight classes, and the population as a whole, followed by calculation of the total allowable catch (fish) as follows: Wu-Y =; Bu · ΔP / B = Ru; Bу + Ру = В, where В is the initial ichthyomass of fish of individual age classes or the whole population as a whole, kg / ha; Y is the total allowable catch of fish of individual age classes or the whole population as a whole, kg / ha; Bu is the remaining ichthyomass of individual age groups classes or the whole population as a whole, kg / ha; where ΔР is the growth of ichthyomass of surviving fish of individual age classes or the whole population, kg / ha; ΔP / B is the recovery coefficient of ichthyomass of individual age classes or the whole population as a whole; Ru is the growth created by the remaining ichthyomass separate x age classes or the whole population as a whole (Vу), kg / ha.
