Breeding of Guppy, Lebistes reticulate Peters, 1859 Under Laboratory Condition
- Breeding experiment of guppy, Lebistes reticulate, one of the popular aquarium fish, was conducted at Aquatic Laboratory of Zoology Department, University of Mandalay. Three colour varieties of guppy were obtained from the local aquarium shop and they were inbreeded to determine the number of offspring, survival rate and sex ratio in each batches and generations. The results showed that mean gestation periods were 23, 27 and 27.33 days in dark yellow, red and pale yellow variety respectively. The highest number of young borne was found in dark yellow variety (29.33), followed by pale yellow variety (22) and red variety (16). Mean survival rate was found in a range of 85.08 % (pale yellow variety) to 93.48% (dark yellow variety). The analysis on sex ratio revealed that the number of males were significantly less in every batch, generation and variety. The data in this work would be useful in producing the desired colour patterns and kind of sex in fish understudy.
