GHOF Research

Long term data from quality scientific research is an essential tool to guide management plans and monitor their effectiveness.

The GHOF and the Guy Harvey Research Institute at Nova Southeastern University are global leaders in tagging and tracking pelagic fish including sharks and billfish.


Projects

The GHOF have aided in a number of scientific projects with financial aid and have actively
participated in documentation and data collection of 12 different projects.

Publications

The Guy Harvey Research Institute has published over 120 peer reviewed papers since it’s inception in 1990.

Research Projects

Shortfin Mako Shark Movement Ecology


 

'Endangered and Decreasing' by the IUCN

About

Shortfinmako sharks are highly targeted by both recreationaland commercial fishermen because, unlike most shark species,there is a seafood market formako meat. Satellite tags are usedto track their movements around the world.

Project Objective

Conduct long term studies to determine critical habitat, migration patterns, discover behavioral differences between sexes and ages and monitor fishing pressure to aid their population recovery.


Tiger Shark Movement Ecology Study​


 

'Near Threatened and Decreasing’ by the IUCN

About

Tiger sharks can be found almost anywhere, from the shallowsof the coral reefs to the deep blue water of the open ocean.They are targets for their liver and fins. Satellite tags are used totrack these sharks around the world.

Project Objective

Conduct long term studies to determine critical habitat,migration patterns, discover behavioral differencesbetween sexes and ages and monitor fishing pressure toaid their population recovery.

 


White shark Genomic Study

 

‘Vulnerable and Decreasing’ by the IUCN

About

White sharks are an important apex predator that often is demonized by themedia and harvested to support thesharkfin trade. Given thatelasmobranchs like the white shark are observed to have reduced incidentsof chronic diseases, scientists are racing to discover the hidden propertiesthat allow them to heal and reduce the presence of cancer.

Project Objective

Continue to uncover hidden secrets of the sharkgenome and provide information that couldaccelerate the rate of healing in human heath.

 


Oceanic White Tip Movement Ecology Study


 

‘Critically Endangered and Decreasing’ by the IUCN

About

Oceanic whitetip sharks were once the most abundantlarge predator on the planet. It is estimated thatpopulations of oceanic whitetips have declined by upwardsof 99% from historical levels in some locations.

Project Objective

Conduct long term studies to determine critical habitat,migration patterns, discover behavioral differencesbetween sexes and ages and monitor fishing pressure toaid their population recovery.

 


Whaleshark Movement Ecology Study​

 

‘Endangered and Decreasing’ by the IUCN

About

The largest aggregation of whale sharks is found off thecoast of IslaMujeres Mexico. IT has become one of themain eco-tourism attractions for Mexico but little isknown about this species natural history.

Project Objective

Provide aid and document migration patterns of individualswho annual return to IslaMujeres aggregation site.

 


Dolphinfish Ecology Study

 

‘Least Concern’ by the IUCN

About

GHOF is in partnership with the Dolphinfish ResearchProgramme (DRP) to tag and release dolphinfishthrough the participation of local anglers during fishingtournaments and recreational fishing.

Project Objective

The DRP aims to integrate the public in an international tagging program to collect data on dolphinfish life history, movements and population dynamics. The DRP also advances the conservation of this incredibly important sport and food fish by requesting anglers to release juvenile fish, allowing them time to reproduce and replenish the stock. Scientific data collection will be conducted in the Pacific and Atlantic Oceans.

 


White Marlin Movement Ecology Study


 

Near Threatened and Decreasing’ by the IUCN

About

Blue, black, white marlin and sailfish are highly targeted by both recreationaland commercial fishermen and are under intense pressure from commerciallongline fishing. Blue and white Marlin Are Both Currently Listed As'Vulnerable To Extinction' By The IUCN.

Project Objective

Conduct long term studies to determine critical habitat,migration patterns, discover behavioral differences betweensexes and ages and other predator species in the same area andmonitor fishing pressure to aid their population recovery.

 


Atlantic Sailfish Movement Ecology Study


 

‘Data Deficient’ by the IUCN

About

Blue, black, white marlin and sailfish are highly targeted by both recreationaland commercial fishermen and are under intense pressure from commerciallongline fishing. Atlantic sailfish are listed as Data Deficient by the IUCN, meaning that there is inadequate information to make an assessment of the species risk of extinction.

Project Objective

Conduct long term studies to determine critical habitat,migration patterns, discover behavioral differences betweensexes and ages and other predator species in the same area andmonitor fishing pressure to aid their population recovery.

 


Atlantic Blue Marlin Movement Ecology Study


 

‘Vulnerable and Decreasing’ by the IUCN

About

Blue, black, white marlin and sailfish are highly targeted by both recreationaland commercial fishermen and are under intense pressure from commerciallongline fishing. Blue and white Marlin Are Both Currently Listed As'Vulnerable To Extinction' By The IUCN.

Project Objective

Conduct long term studies to determine critical habitat,migration patterns, discover behavioral differences betweensexes and ages and other predator species in the same area andmonitor fishing pressure to aid their population recovery.

 


Eastern Tropical Pacific Seascape Program​

About

The ETPSP is focused on studying the ecology and movement patterns of major game fishes and sharks using state-of-the-art satellite and acoustic tracking in the waters surrounding Tropic Star Lodge and extending throughout the Eastern Tropical Pacific Seascape (ETPS).

Project Objective

Conduct long term studies to determine critical habitat,migration patterns, discover behavioral differences betweensexes and ages and other predator species in the same area andmonitor fishing pressure to aid their population recovery.

 


Southern Stingray Survey

 

‘Data Deficirnt’ by the IUCN

About

The stingrays at Grand Cayman’s Stingray City are a unique wildlifeinteraction zone that contributes hundreds of thousands of dollars per yearto the Cayman Island's Economy. With increased demand to see the stingraysthe GHOF work to monitor human impacts on these animals and have beendoing so with the Cayman Islands Department of Environment since 2002.

Project Objective

Continue to monitor the population dynamics to aid in themanagement of the site.
