Reproducción normal y asistida del betta splends en condiciones de acuario en la estacion de maricultura fca-utmach

Abstract

The following degree work was carried out at the FCA-UTMACH Mariculture Station, which is located within the Faculty of Agricultural Sciences of the Technical University of Machala which is located at Av. Panamericana Km. 5 1/2 Vía a Pasaje . The research was carried out in two ways: the acclimatization and preparation of the reproducers, to end with the reproduction, where the first part consisted of supplying artificial food and live food, in which a treatment was made that later had to be modified, this The modification consisted of the male brood fish because only 87.5% of the fish liked the live food and did not ingest the artificial food, while 12.5 gave preference to the balanced food, the objective was to evaluate the acclimatization of the reproducers, prepare them with natural and artificial food, evaluating the acceptance of each of the foods and end with the reproduction of the Betta splendens fish, having a higher expenditure on natural food due to the fact that the peanut weevil strains were acquired, but the maintenance of these turned out to be economical and giving a good result in the feeding of the fish, the temperature n or it was a problem because the climate where the work was carried out was in the FCA-UTMACH Mariculture Station has a regular climate and it also helped that the practice was carried out in a closed place without having direct effect of the sun, the temperature of the water was regular. The Cabomba sp. I am a fundamental part of the reproduction because it served as a hiding place for the female and for this reason, when the reproducer was separated, it came out unharmed, with rapid recovery after spawning. Good results were obtained with the natural feeding provided since the vitality and color of the fish could be appreciated, in addition to the time of finishing the reproduction, no greater energy wasted was felt, even the size of the nests were large and this could be influenced because the live food more motivated the natural instinct of these fish. Likewise, it was possible to appreciate the bulge that the females obtained when feeding them, it should also be emphasized that they were acquired when they were 4 months old. There were no reproductive mortality problems or diseases. A lower cost was obtained in artificial food with a value of $ 5.15, while in natural food the consumption was $ 14.95 but it must be considered that the live food had the greatest taste, the expenditure we obtained was also taken With the aquarium conditioner that was $ 24.46, which is a higher consumption because the dechlorinator was of a seachem brand, being very good and recognized, in addition to eliminating chlorine, it eliminates chloramine and also lowers the level of ammonium, nitrite and nitrate . It was decided to use this additive to treat the water before entering our fish for the reason that this brand was recommended for its quality and effects, even because they were line specimens, in addition to achieving rapid acclimatization in a short time and there is no stress due to water parameters such as differences in pH, chlorine and chloramines.
