Direct observation

Insights into the secret life of fish

Observational studies on fish require the observer to directly enter the fishs' own environment. Underwater videography and still photography are powerful tools for the marine zoologist that provide scientists the opportunity not only to observe, directly, phenomena of interest, but also to collect data over sufficient periods of time so that quantitative analyses are possible.

Moreover, it has long been recognized that direct observations by divers can yield valuable information on the behaviour and ecology of fish. Because underwater observations are made in the natural environment of the animal often without any manipulation, behavioural observations are mainly anecdotal in nature. Nevertheless, the results can provide excellent preliminary data that benefit from follow-up studies using other methods or provide researchers with rare opportunities to witness complete and natural acts of the secret life of fish.
