Monk Seal Prey and Nutrition Study

Project Investigators – Shannon Atkinson, Ph. D., and Gwen Lowe
Affiliate Organizations – Dolphin Quest and University of Hawaii at Honolulu
Dolphin Quest Supported – 1996
Project Description
This project studied the Hawaiian monk seals at the five main breeding islands to see if they were feeding on different prey and if there was a difference in diet among adult male, adult female and juvenile seals. Once the prey were identified, the next focus was to understand how well the seals digest them and how many calories, proteins, etc. they provided. This project was conducted to attempt to explain the selective starvation seen in the North West HI.

The survival and management of a stranded and injured Hawksbill turtle

Affiliate Organizations – Bermuda Aquarium, Museum & Zoo (BAMZ)
Species – Hawksbill turtle (Eretmochelys imbricata)
Dolphin Quest Supported – 2009-2011
Project Description
A stranded hawksbill turtle (Eretmochelys imbricata), found floating at the surface of Bermuda waters and having difficulty diving, was brought to BAMZ. The turtle had sustained traumatic injury to its spine near the pelvic region, which caused the turtle to not be able to adjust buoyancy or dive.
♦ Deemed non-releasable, the turtle was fitted with a weight attached to its carapace, allowing compensation for buoyancy and enabling it to sit on the bottom of the lagoon.
♦ Once adjusted to the new weight, the turtle was housed at Dolphin Quest Bermuda, providing a larger natural lagoon environment and allowing the turtle plenty of space to exercise. Dolphin Quest Bermuda was responsible for the nutrition, health care and daily management of the turtle.
Marine Mammal/Conservation Benefit
Individual survival for turtle rescued
♦ Development of care and rehabilitation strategies and devices which could be used in future stranding

The Dynamics of a Natural and Human System in the Coastal Waters of Hawai‘i: Understanding Spinner Dolphin Marine Tourism and Human Perceptions

Project Investigator – Carlie Wiener
Affiliate Organization – University of Hawaii
Dolphin Quest Supported – 2012-2013
Project Description
Swimming with dolphins in the wild can negatively influence their behavior; however, dolphin tourism continues to expand. Human actions are rarely considered in biological studies, thwarting species protection.

Conservation Benefit
♦  
The information gathered from this scientific study can be used to raise public awareness about the risks to dolphins from wild swim with dolphin programs, and influence humans to reconsider these interactions in the future.

Training and Certification to treat Hawai`i anchialine pools with rotenone

Project Investigator – William Gilmartin
Affiliate Organization – Hawaii Fish and Wildlife
Dolphin Quest Supported -2013
Project Description
A major cause of degradation of Hawai`i’s endemic anchialine pool ecosystems has been the human introduction of fish into the pools, usually tilapia. Once in the pools they are essentially impossible to eradicate, without the use of rotenone.
♦ The State has not allowed rotenone use in recent years, but now the Department of Health is modifying the rules to allow limited use of the chemical.
♦ This project is to send a person to a Fish and Wildlife Service training and certification course to enable use of rotenone in Hawai`i Island anchialine pools.
Conservation Benefit
The training and certification enables this project the use of rotenone to remove invasive fish species from the anachialine pools and help to restore these ecosystems.
♦ The certification will also allow HWF to assist other groups attempting to restore these threatened native Hawaiian ecosystems.

Postnatal Development of the Muscle Biochemistry that Supports Swim Performance in Spinner Dolphins: Modeling Calf Vulnerability to Separation from the Pod During Interactions with Tuna Purse-seine Fisheries

Project Investigator – Shawn Noren, Kristi West
Affiliate Organization – University of California, Santa Cruz, and Hawaii Pacific University
Dolphin Quest Supported – 2014
Project Description
♦ 
In collaboration with Dolphin Quest, the swim effort and performance of bottlenose dolphin calves was quantified to model the potential of fishery induced chase to separate spinner dolphin calves from their mothers (Noren et al. 2006, Noren et al. 2008, Noren and Edwards 2011)
♦ 
To refine these models, species-specific development of the muscle biochemistry that supports swim performance must be quantified
♦ This study will examine how the aerobic and anaerobic capacity of the major locomotor muscle changes after birth in spinner dolphins so that the age of vulnerability for separation during fishery induced chase can be identified
Conservation Benefit
♦ 
Due to a lack of physiological data on spinner dolphins, the bottlenose dolphin has served as a model to assess the potential for immature spinner dolphin calves becoming separated from their pod during the high speed, long duration chases induced by tuna purse-seine fisheries in the eastern tropical Pacific.
