Fisheries Ecology & Enhancement

Our Work

The Fisheries Ecology & Enhancement Program advances science to support abundant, productive fish populations.

We develop innovative tools and methods to help natural resource managers and others replenish and monitor fisheries.  Our responsible stock enhancement approaches focus on improving fish survival and promoting important connections between fish and their ecosystems, and they are designed to benefit fish populations, habitats, fishers and the economies that depend on fisheries. Our projects involve both traditional and technological monitoring of fish and fisheries, from seine sampling in the tidal creeks to electronic monitoring of coastal fisheries.

Why Fisheries Enhancement Matters

Saltwater recreational fishing contributes $8 billion annually to Florida’s economy, and in general, productive coastal waters help communities thrive by providing economic stability and recreational value. However, fisheries in Florida and beyond face significant challenges, including degraded habitat, reduced water quality, overfishing of some species, harmful algal blooms and more.

Fisheries enhancement (via stocking) involves raising juvenile fish in hatcheries and releasing them into the environment strategically, to improve fishery yields and/or benefit species conservation. To be effective, stock enhancement must be done responsibly and be driven by the best available science.

The Best Available Science

Mote scientists are working to resolve critical uncertainties about marine (saltwater) stock enhancement and help foster development of responsible and effective approaches to:

• Improve survival of hatchery-reared and wild fish to augment fishery yields and restore depleted marine fish populations
• Apply non-invasive monitoring techniques that can help with threatened and endangered species conservation.
• Advance basic knowledge about wild fish stocks and their ecology.
• Aid in restoration of natural ecosystems and improvement of artificial habitats to support existing fisheries or establish new ones.
• Respond rapidly to mitigate the impacts of ecological emergencies such as harmful algal blooms and cold stuns that cause major fish kills.

Critical Partnerships

Many fisheries around the world—including sportfish and seafood species—are struggling to keep pace with the pressures of our growing human population. We strive to assist developing fisheries enhancement programs around the world by engaging together in research to develop specific guidelines for strategic stocking and effectively respond to these critical challenges. Mote’s Fisheries Ecology & Enhancement Program works closely with national and international partners and with Mote’s Marine & Freshwater Aquaculture Research Program, which advances sustainable methods for farming animals and plants in water—known as aquaculture.  Our partnerships allow the Fisheries Ecology & Enhancement program to investigate new species for stock enhancement research, especially species that have never been mass produced before in hatcheries, and to pursue new avenues to promote responsible stock enhancement research and development.

Another key local partner in our fisheries ecology and enhancement research is the Florida Fish and Wildlife Conservation Commission’s Fish and Wildlife Research Institute (FWRI), which manages a Stock Enhancement Research Facility (SERF). This unique partnership has enabled a team effort in developing, testing and evaluating the effectiveness of stock enhancement as a fishery management tool in Florida. The researchers and fishery managers working together in this partnership are providing the scientific information needed to enable a responsible, adaptive-management approach in conducting and refining stock enhancement in Florida.

We share fisheries science and sustainable fishing practices with our communities by working with local fishing groups, hosting kids’ fishing clinics in partnership with Mote’s Education team, and partnering with stakeholder groups, such as the Sarasota Bay Fisheries Forum, to connect community members with fisheries management and research.

Electronic Monitoring

Center for Fisheries Electronic Monitoring at Mote (CFEMM) develops and assesses electronic monitoring (EM) technology as a tool in the Gulf of Mexico commercial reef fish fishery to better meet the demand by industry and management for accurate, independent data to ensure long-term fishery health.
