添加标签 | 总结: | This research bases its studies on the tadpoles’ development of Andean marsupial frog (Gastrotheca riobambae) in different nutritional conditions, with the objective of evaluating three types of diets for feeding tadpoles, determining its maturity stage, morphometric values for metamorphosis and the percentage of mortality 30 newly hatched tadpoles, of the same mother, were selected by identifying and manipulating variables in the form ex situ for each of the treatments.He applied completely randomized design (DCA).The results determined with the T2 SAR (super food for tadpole) ended its metamorphosis on 117, followed by T1 food for carnivorous fish that ended the day 119, the T0 food for herbivorous fish (seaweed) remained as tadpoles until the investigation end. Regarding morphometric values, were recorded in millimeters these being the T1 which had better measures regarding the width head, over the head, tail length and body length, followed by T2, the greater weight T1 obtained with 1,082 grams, 0,568 grams followed by T2…. |
