Abstract
This study aimed to analyze the relationship between sampling locations and biological variables of Octopus cyanea in Indonesian waters. Understanding the distribution and biological characteristics of this species is crucial for conservation and resource management. Sampling was conducted in the Alas Strait from July 2023 to June 2024, covering six stations with different environmental variations. Data collected included body size (length and weight) and geographic coordinates. Data analysis used descriptive statistics, Pearson correlation, and regression to explore the relationship between location and biological variables. Principal Component Analysis (PCA) results showed significant morphometric variation among individuals. Regression analysis showed a strong relationship between octopus length and weight at all stations, following an allometric growth model. Variations in sea depth and currents also contributed to differences in growth patterns. This study emphasizes the importance of environmental factors in influencing the growth and size of O. cyanea, with implications for sustainable fisheries management strategies.
