FishCaduceus

FishCaduceus is a family of single-nucleotide DNA language models developed for cyprinid and comparative fish genomics.

The project provides:

• pretrained FishCaduceus models with 512-bp and 1,024-bp context lengths
• pretraining datasets from seven major cyprinid aquaculture fishes and zebrafish
• cross-species benchmarks for translation initiation, translation termination, splice donor and splice acceptor prediction
• evolutionary constraint benchmarks derived from a 26-fish whole-genome alignment

FishCaduceus is designed for fish genome annotation, cross-species transfer, evolutionary constraint analysis and zero-shot variant prioritization.
