They make surveys to determine how much forage is available for the animals to eat. Biologists collect specimens for laboratory study or make a laboratory analysis of the specimens.

For example, biologists collect data in the field, including samples, of marine, fresh water or anadromous fish, and other aquatic organisms. They determine fish population levels by surveying streams, rivers, and lakes.
Biologists capture and tag various fish species for examination of laboratory analysis.

They also compile and evaluate research data and prepare technical reports.
