Title : Growth pattern studies on fish body length weight and otolith length weight relationship
Abstract:
This study examines the relationship between fish body morphometrics (length and weight) and otolith dimensions (length and weight) to evaluate the strength of association between somatic and otolith growth. Otolith-based analyses are among the most significant approaches in contemporary fisheries science for understanding fish life histories. In this study, fish body lengths were measured using a vernier calliper, and body weights were obtained with an electronic scale. Otoliths were extracted from the cranial cavity, measured for length using a vernier calliper, and weighed using a microscopic electronic scale. The results revealed a positive correlation between fish body length and weight, indicating that somatic growth is closely associated with otolith development. Additionally, larger fish exhibited a strong positive correlation between body length and weight, while smaller fish showed a pronounced correlation in otolith length-weight relationships. These findings suggest that both somatic (length-weight) and otolith (length-weight) measurements are critical parameters for assessing fish growth patterns and understanding species-specific growth dynamics.
