# R-eca - Estimating Catch-at-Age
Reca is a package made for the Institute of Marine Research. The package produces predictions of catch-at-age,
i.e. the number of fish caught within each age group, of different fish species.
Predicting the catch-at-age of commercial fish species is an important part of the quota-setting process for
many diferent species.
The Norwegian Computing Center and the Institute of Marine Research have over years developed a Bayesian
hierarchical model to estimate the catch-at-age of fish.
The model aims to estimate both the proportion-at-age and the mean weight of fish, in order to convert
total landings statistics to numbers at age.
## Functions
The package consists of two main functions; `eca.estimate` and `eca.predict`
