THE RELATIONSHIP BEETWEEN THE NUMBER OF FISH OFFSPRING AND WATER TEMPERATURE AND ALSO THE STYDY OF DIFFERENT BEHAVIORS OF LIVE BEARING AQUARIUM GUPPY FISH SPECIES

Introduction: Different factors such as physical and chemical factors of water will affect the survival and the growth of fish because fish lives in water. The most important factors are included temperature, density, and soluble Oxygen. The increase in density and temperature will affect the growth of fish in an undesirable way. In this research, we want to increase the efficiency and the number of fish newborns by surviving and conducting tentative actions, temperature variations, and nutrition diets. Research process: present research was conducted on two Aquariums in spring, summer and fall of 1392. Aquariums were included eighty live bearing Aquarium Guppy fish species. This research was conducted within ninety days. Researchers divided these two Aquariums into four parts. Researchers inserted heaters in each part of these two Aquariums to adjust the temperature of these parts. Researchers regulated the temperature of these parts on 23, 25, 28 and 32 ° C. Also results were shown on the tables and graphs. Also, the behavior of fish was surveyed with watching the Aquariums. Results: We expect that the increase in temperature between 23 to 28 ° C will increase the number of full grown newborns in Guppy species based on the observations. Also, we expect that the increase in temperature between 28 to 32 ° C will decrease the number of full-grown newborns in Guppy species. Discuss and Deduction: With regard to the above results, we can say that the relative increase in temperature will affect the evolution process of growing newborns in a positive way. In contrast, great increase in temperature will affect the evolution process of growing newborns in a negative way. Based on the results of behavioral observations in Guppy fish, we expected that there were no social relations between Guppy fish species in the case of nutrition and swimming. In fact, Guppy fish species are mobile and sociable at the time of swimming and make a good social relationship with their species and the environment of the Aquarium.
