• Host specificity. Collecting a wide variety of fish species (salmon, halibut, rock fish, crab, shrimp)

• Temporal data. Season, years, within a day

• Complete individual biological metadata. Fish are killed so we have access to all organs.

• Additional data from hatchery companies. Fish bred in a farm have specific characteristics.

• Large sample size. Many tourist companies.

• Geographic data. Fish companies operate at different locations.

• Possible catch and release data.
