Bases for morphometric study of Cottus sp. fish

Collection of photographs of individual fish in a growth experiment performed in two temperature treatments. Photos are divided into "before" and "after" incubation period. Information about fish - their population of origin, lineage and temperature treatment they were incubated in - is available in "box_decoding.xlsx" file. Growth rate of individual fish was assessed based comparing size of animal before and after the experiment by geometric morphometric methods.
