The purpose of this study is to evaluate the relationship between food consumed and the gross conversion efficiency (K) of scalloped hammerhead sharks. We are holding juvenile sharks in controlled captive environments and feeding them a variety of daily rations (from 1.5% of their body weight to all-they-can-eat). During the experiment, we are quantifying their weight change, daily intake, and activity rates. In addition, factors known to affect growth such as water temperature, ph, salinity, and day length are being measured. As part of our GK12 goal of integrating research with education, we are working with a number of teachers and schools to combine classroom work with field research. Classroom lessons are geared to teach students about marine ecology, especially the roles of predators and sharks in that environment. The field component is at the Hawaii Institute of Marine Biology (HIMB) where students are responsible for feeding and maintaining the sharks as well as collecting data. The end goal is for students in this project to have a positive experience working with sharks while at the same time have an opportunity to interact with the marine environment that is such an important part of life in Hawaii.
