   "rai:dataLimitations": "The dataset is limited to sonar-based fish counting in riverine environments and may not generalize to other sensing modalities (e.g., optical video), marine/open-ocean settings, or species with substantially different motion or morphology. While expanded to nine river systems, geographic and ecological coverage remains incomplete (North America only), and certain river conditions (e.g., extreme turbidity, rare seasonal events, or atypical flow regimes) may be underrepresented. Annotation quality may be affected by low signal-to-noise ratios and ambiguity in fish visibility, particularly in dense or occluded scenes. The dataset is not recommended for tasks requiring fine-grained species classification, individual fish re-identification, or appearance-based recognition independent of motion cues.",
   "rai:dataBiases": "The dataset may exhibit selection bias toward rivers and deployment sites where sonar systems and data collection is feasible, potentially over-representing current sites of interest in North America. Environmental conditions (e.g., typical flow, sonar artifacts) and species distributions may be unevenly sampled, leading to skewed representations of fish behavior and density. Label bias may arise from human annotation under low-visibility conditions, where temporal cues are required and ambiguous cases may be inconsistently labeled. These biases may cause models to overfit to common environmental patterns or fish movement dynamics and underperform in rare or extreme conditions.",
