摘要： [Objective] The paper was to formulate catchable size and total allowable catch of crucian carp in the Yellow River waters. [Method] Based on analysis of length-weight formula, body length and weight growth equations, and instantaneous mortality rate, the inflection age and critical age and weight growth were calculated, and the biomass of crucian carp in the Yellow River waters was estimated. [Result] The growth equation of body length was Lt = 278 * [1 - e~(-0.38) (t + 0.39197)], _(an)d _the growth equation of the body of weight was Wt = 680.6 * [1 - e~(-0.38)(t + ~(0.39197))]~(3.2049); the inflection age and critical age for weight growth of crucian carp were 2.67 and 3.01 a, respectively. The biomass in the Yellow River waters area was about 6088 t. [Conclusion] For the crucian carp flock in the Yellow River waters area, the catchable length was about 191.2-201.6 mm, the catchable weight was about 204.9-243.4 g, and the total allowable catch was about 7186.83 t.
