Resumen
To carry out the study of the population structure of Procambarus clarkii (Girard, 1852), in the lagoon of Fúquene, Cundinamarca, visits were made to three areas surrounding this place, beginning the field phase in the month of February and ending in July of 2017, executing manual captures and craft traps in linear transepts, recording the environmental and water conditions through equipment such as turbidimeter, potentiometer or Aquamerck tests; this with the aim of providing knowledge in the biological area that explains the most important adaptive mechanisms and characteristic behaviors, which have made this species is considered as the largest invasive locust population in the world, this research was developed from four approaches that allowed recognize and characterize that the structure of the population found presents a constant growth and a sexual ratio of 1: 1 with respect to males and females; that the comparative morphology between both sexes revealed that only in the clamp there are significant differences in length and width, than the variation between the individuals of the population in each of the 4 structures selected for this purpose (abdomen, carapace, clamp and telson) ) was related to the size thanks to the bodily differences between the individuals according to their stage of maturity; and finally, that the correlation present between the appearance and settlement of this species with reference to water and environmental conditions occurs predominantly in factors such as relative humidity, dissolved oxygen, conductivity and turbidity, among others; allowing to conclude that the population of this species for the Fúquene lagoon presents a considerable number of individuals that maintain a population stability during this period, due to its total adaptation with respect to the presence of aquatic vegetation (specifically E. crassipes) and to the conditions water physicochemical and environmental in general.
