Which of the following predicts the length of a fish as a function of its age?

Correct option is C

Correct Answer: (c) von Bertalanffy growth function (VBGF)
Explanation:
→ VBGF is the most widely used model to predict fish length-at-age.
→ Expressed as Lt = L∞(1 − e^{−k(t − t₀)}).
→ Parameters reflect growth rate, asymptotic size, and developmental timing.
Information Booster:
→ Essential for stock assessment and management.
→ Helps determine age structure and mortality.
→ Applied across marine and freshwater species.
Additional Information:
(d) Gulland–Holt is used for estimating growth parameters, not direct prediction.
