I will be investigating the mating strategies and behavior of Giant Sea Bass. They have been largely overfished since the late 1800's, causing them to land on the IUCN Red List as critically endangered. Despite its popularity, few studies have been done and much of what is known is speculative. Researching mating strategies allows for better understandings of the functions of this mysterious beast and is vital to its preservation.


Budget Overview

DSG-Ocean Acoustic Datalogger- is a long-term hydrophone (underwater microphone) essential for getting the most accurate results, allowing me to analyze mating strategies and describe spawning behavior of giant sea bass in detail.

I also need to feed my field assistant! I know they would just to eat peanut butter and Oreos all summer with me (that's my field food), but maybe a pizza would be nice from time to time.

Stretch goals
Extra funds will be used to purchase supplemental equipment to ensure the validity of the data.

  • Underwater video cameras will be used for visual observations
  • Hydrophones (connected to video cameras) to validate the sounds heard made by the giant sea bass.
  • iButton- Temperature Datalogger will allow for continuous temperature readings
