Comparative analysis of the relationship among age, weight, and energy requirement of common bottlenose dolphin (Tursiops truncatus)

Abstract. The common bottlenose dolphin (Tursiops truncatus) is a well-known cetacean species, often seen in documentaries and captivity, such as zoos and aquariums. This study explores the relationships among age, weight, and energy requirements of captive dolphins to discover better dietary plans and care practices. Using data from three longitudinal studies conducted in the early 2000s, this research analyzed dolphins' body measurements and energy requirements. The findings reveal a positive correlation between the age and weight of bottlenose dolphins, suggesting that as dolphins age, their weight tends to increase. Conversely, a negative correlation between age and energy requirements, as well as weight and energy requirements, indicates that older and heavier dolphins require less energy per kilogram of body weight. These trends align with the results of the previous study; however, due to lactating females exhibiting significantly higher energy needs, the overall correlation levels were affected. These results underscore the importance of tailored feeding protocols based on dolphins' age and weight. To improve future studies, it is recommended to use standardized methodologies for measurement and sample selection and to expand the range of data sources. These results highlight the necessity of customized feeding protocols based on the age and weight of dolphins. To optimize the accuracy and representativeness of future analyses, it is recommended that methodologies for measurement and sample selection be standardized, and the range of data sources be broadened. This holistic approach will ultimately facilitate peoples understanding of dolphin physiology and contribute to better conservation and welfare practices.
