Reproducción del pez Betta Splenders. Regan 1910 mediante el control de temperatura y alimento vivo para la obtención de machos

Abstract

The Siamese fighting fish (Betta splendens) is one of the most popular ornamental aquarium fish in the world trade, where within this species the males are the most sought after for commercialization due to their larger size, longer fins and striking color patterns compared to the females. Reproduction is a challenge for many producers due to the lack of scientific information and added to this, finding a technique that allows obtaining the highest percentage of male betta fish fry for sale.For this reason, in the present study an investigation was carried out to determine the effect that temperature and type of feeding have on the reproduction of this species in order to find an effective method to influence the sex ratio and to obtain the highest number of male specimens in the reproduction of the Betta splendens species. Two breeding pairs wereacquired which were put into reproduction to obtain F1 specimens which were waited for their sexual maturation, and then 18 pairs were selected for the research, these were transferred to 18 40L tanks, the ratio of male:female was 1:1.
