Adaptación de la preñadilla (astroblepus sp) a los factores bióticos y abióticos en cautiverio en el centro experimental Salache.

Environmental pollution is one of the most overwhelming problems nowadays, as well as the indiscriminate felling of forests, agricultural frontier and industrialization, problems that have been dragging, harming the quality and quantity of water. The species, (Astroblepus Sp), is a group of legendary fish of the Ecuadorian highlands. The purpose of this project was to determine the adaptation of the preñadilla (Astroblepus Sp) through the biotic and abiotic factors in captivity for its conservation in the Salache Experimental Center, 25 species of different size, weight and length were employed, water analysis, temperature, pH, dissolved oxygen, weight and length measurements were taken, obtaining initial and final records on the process of adaptation, survival, mortality and growth; the methodology of measures of central tendency of the population, scientific literature and observational direct descriptive statistics were used. The research demonstrated and confirmed that the biotic results of the species were fed by providing them with artisanal worm meal with 52% protein, the species studied demonstrated their capacity to adapt to captivity and to new environmental conditions, achieving an increase in their average weight of 3.56 g, and ended with a weight of 3.61 g, likewise their average length at the beginning was 4.96 cm and ended with a length of 5.09 cm, obtaining a growth rate of 5% in weight and 13% in length. Ending with the results obtained for the abiotic parameters such as water physicochemical parameters, temperature, pH, dissolved oxygen, the average environmental temperature was 22.1°C, water temperature average 18.6°C, dissolved oxygen was 7.20 ppm and pH 7.5; in terms of survival, 92% was obtained; in mortality it was obtained 8%. It was concluded that the species under study demonstrated their capacity for adaptation and conservation to biotic and abiotic factors, accepting food and adapting to climatic variations, ending with a growth development in weight and length in captivity.
