ABSTRACT

Regression analysis of Australian freshwater crayfish (Cherax quadricarinatus) revealed power function relationships between body length (L) and weight (W) across age groups: W = 1.2995L^0.986 (R² = 0.9538) for 1-month-old, W = 0.3468L^1.3747 (R² = 0.9242) for 2-month-old, W = 2.852L^0.4004 (R² = 0.9704) for 3-month-old, and W = 2.5846L^0.4238 (R² = 0.9404) for 4-month-old individuals, while daily feed intake (F) correlated with weight as F = 0.013W^1.014 (1-month), F = 0.047W^0.7274 (2-month), F = 0.0012W^2.4975 (3-month), and F = 0.0018W^2.3598 (4-month), demonstrating peak growth at 2 months with significant deceleration by 4 months, suggesting optimized farming practices—increased feeding, water exchange, or aeration during the second month and harvest after 4 months.
