Area of Science:

  • Marine Biology
  • Ecological Research
  • Oceanography

Background:

  • Underwater video and image data are crucial for ecological research.
  • Existing underwater camera systems can be expensive and complex.
  • There is a need for accessible, low-cost solutions for underwater observation.

Purpose of the Study:

  • To introduce the FishCam, an inexpensive, autonomous underwater camera system.
  • To demonstrate the system's capability for extended video data collection.
  • To highlight its potential applications in ecological research and citizen science.

Main Methods:

  • The FishCam utilizes readily available components and an 8-megapixel camera.
  • It is programmable for scheduled operation and includes an optional buzzer for acoustic synchronization.
  • Ten deployments were conducted off Vancouver Island, Canada, over a year.

Main Results:

  • The FishCam successfully recorded up to 212 hours of video data over 14-day periods.
  • Data collected enabled fish species identification and observation of interactions.
  • Field tests confirmed the system's reliability and durability.

Conclusions:

  • The FishCam is a cost-effective and reproducible tool for expanding underwater observation.
  • It enhances temporal and spatial data collection in ecological studies.
  • Its simplicity makes it suitable for educational and citizen science initiatives, promoting STEM learning.
