# FishDet-M: A Unified Large-Scale Benchmark for Robust Fish Detection
[](https://arxiv.org/abs/2507.17859)
[](https://lyessaadsaoud.github.io/FishDet-M/)
## Overview
FishDet-M is the largest unified benchmark dataset for fish detection in diverse underwater environments, designed to advance ecological monitoring, aquaculture automation, and marine robotics.
## Key Features
- **📊 Dataset Scale**: 105,556 images with 296,885 annotated fish instances
- **🌊 Diverse Environments**: Marine, brackish, aquarium, and occluded scenes
- **🎯 Unified Format**: COCO-style annotations with bounding boxes
- **🤖 28 Models Evaluated**: Including YOLOv8-v12, DETR, R-CNN variants, and more
- **🧠 CLIP-Based Selection**: Automatic model selection using vision-language alignment
## Dataset Composition
FishDet-M integrates **13 public datasets** spanning:
- Coral reefs and open water
- Aquaculture tanks and ponds
- Clear to highly turbid conditions
- Single fish to dense schools (1-256 instances per image)
- Image resolutions: 78×53 to 4608×3456 pixels
## Performance Highlights
**Top Performing Models:**
- **YOLO12x**: 0.491 mAP (best overall accuracy)
- **YOLO11l**: 0.484 mAP with excellent efficiency
- **YOLOv8n**: 251 FPS for real-time applications
**CLIP-Guided Selector:**
- Dynamic model selection: 0.444 mAP at 80 FPS
- Zero-shot adaptation to diverse scenes
## Key Contributions
1. **Unified Benchmark**: First large-scale dataset harmonizing diverse underwater fish detection datasets
2. **Comprehensive Evaluation**: Systematic comparison of 28 state-of-the-art detection models
3. **Adaptive Selection**: CLIP-based framework for context-aware model deployment
4. **Deployment Guidelines**: Performance insights across occlusion, scale, and visibility conditions
## Applications
- 🐠 Ecological monitoring and biodiversity assessment
- 🎣 Aquaculture automation and fish counting
- 🤖 Underwater robotics and autonomous vehicles
- 🔬 Marine conservation research
