FishEggs

Description

Fish Eggs

Format

A dataset with 35 observations on the following 4 variables.

Age Age of the fish (in years)
PctDM Percentage of the total egg material that is solid
Month Month fish was caught: Sep=September or Nov=November
Sept Indicator with 1=September or 0=November

Details

Researchers collected samples of female lake trout from Lake Ontario in September and November of 2002 through 2004. A goal of the study was to investigate the fertility of fish that had been stocked in the lake. One measure of the viability of fish eggs is percent dry mass(PctDM) which reflects the energy potential stored in the eggs by recording the percentage of the total egg material that is solid. Values of the PctDM for a sample of 35 lake trout (14 in September and 21 in November) are given in this dataset along with the age (in years) of the fish.
