Predict hatch and emergence timing for a wide range of wild fishes using the effective value framework (Sparks et al., (2019) <doi:10.1139/cjfas-2017-0468>). 'hatchR' offers users access to established phenological models and the flexibility to incorporate custom parameterizations using external datasets.
