juvenile_growth

A dataset containing daily growth data for juvenile Galaxis maculatus.

datasets

A collection of four datasets
based around the population dynamics of migratory fish. Datasets
contain both basic size information on a per fish basis, as well as
otolith data that contains a per day record of fish growth history.
All data in this package was collected by the author, from
2015-2016, in the Wellington region of New Zealand.
