The experiment was conducted in zoology laboratory of the Universidade Federal do Piauí,Campus Professor Cinobelina Elvas, in the city of Bom Jesus. They used 15 couples Betta splendens ofreproductive age and 15 plastic circular tanks translucent with conical bottom with a capacity of 10L of waterbeing measured at 28, 12 and 8 cm of water column. The experiment was conducted in a completely randomizeddesign with 3 treatments and 5 replicates per treatment, the results were submitted to variance analysis at thelevel of 5.0%, and the averages compared by Tukey test through BIOESTAD 5.0. The results show that forreproduction Betta splendens can be used water column 8 cm in this experiment.(AU)
