Randomized trial reveals the impact of ageing error on fish age predictions, suggesting robust model performance.

The study aims to quantify the impact of observation error on neural network predictions of fish age.
Conducted an empirical study coupled with simulation
Used a multimodal convolutional neural network (MMCNN) model
Evaluated the model on eastern Bering Sea walleye pollock ages using FT-NIRS
Model performance decreased slightly with ageing error from R2 = 0.92 to R2 = 0.87
Coefficient of variation increased from 7.6% to 10.2%
MMCNN model exhibited high repeatability between instrument operators

Chamberlin et al. (2026) studied this question.
