Reproduction of Siberian shrimp Exopalаemon modestus (Heller) from the Kapchagai reservoir (Republic of Kazakhstan): reproductive performance and fecundity

Year: 2024

Type: article

Abstract: The elements of reproductive performance of Siberian shrimp Exopalaemon modestus (Heller) from Kapchagai reservoir (Republic of Kazakhstan) were studied. The value of reproductive performance was estimated in comparison with other shrimp species from the family Palaemonidae. Palaemonidae that in the middle of the growing season (July) was 0.24. The equations for the relationship between the oviposition weight and the weight of sexually mature females were calculated. The value of absolute fecundity averaged 68 ± 19 eggs (s. d.) to a female length of 35.8 ± 3.29 mm (s. d.). This relationship is described by the regression equation (determination coefficient R2 = 0.583). Reproductive performance should be evaluated and analysed taking into account the age structure and time of the growing season.
