# fish-boxes

Reef Support Marine Data v1.0 (October 2026). Part of [reefsupport/marine-data](https://huggingface.co/datasets/reefsupport/marine-data).

Fish and fauna photos with bounding boxes (`x_min`, `y_min`, `x_max`, `y_max` normalised to 0-1, native `label`). 25,912 images; splits: test 3,472, train 18,967, validation 3,473. Upstream splits are kept where present, otherwise a `split_group` hash. The build ran a deduplication gate.

## Columns

image_sha256, image, source_id, license, licence_class, attribution, boxes, points, split, split_group, upstream_id, upstream_url, lat, lon, depth_m, meow_realm, habitat, width, height

## Image provenance

Images in this configuration originate from UIIS, UIIS10K and USIS10K, distributed by their authors under the Apache License 2.0. The original publications state that the images were gathered from public sources and earlier datasets, so copyright in individual images may rest with third parties. Rights holders can request removal via https://github.com/reefsupport/marine-data/issues or https://www.reef.support/contact.

## Notes

- Boxes for `uiis`, `uiis10k` and `usis10k` are derived from the upstream instance annotations, one box per instance. Boxes for `roboflow-aquarium` are the source's own.
- This configuration uses the US spelling `license` for the licence column.

Changes made by Reef Support: images and masks were re-encoded into Parquet, `class_map` or `instances` were added, and splits and `split_group` were assigned.

## Load

```python
from datasets import load_dataset
ds = load_dataset("reefsupport/marine-data", "fish-boxes")
```

## Files

`README.md`, `LICENSE`, `NOTICE` and `CHECKSUMS.sha256` (sha256 of every file of the configuration). To verify the data files: `grep ' data/' CHECKSUMS.sha256 | sha256sum -c -` from a directory that contains `data/`.
