- To estimate the size of a fish population
- To measure changes in body size
- To distinguish between different age groups of fish
- To quantify the period of time between release and recapture (correct)

What assumption must be met in order to gain insights into the size of the fish population?
- The distribution of lengths must be unimodal (correct)
- The age group of the fish must be known
- The fish must be hatchery-reared
- The period of time between release and recapture must be quantified
