ASSESSMENT OF MIGRATORY BEHAVIOR AND HABITAT UTILIZATION OF SPORT FISH
This project conducts research on migratory behaviors and habitat utilization of Tripletail and Cobia to aid in effective management of these sport fish species. These species are tracked using acoustic telemetry and pop-up satellite tags to provide information on movements in Mississippi coastal waters from late summer into the cooler months when the fish migrate further south.
Tagging efforts for Atlantic Tripletail were conducted from August 21 to September 30, 2019. Ten fish were equipped with satellite tags and these were the first Atlantic Tripletail to receive satellite tags in the Gulf of Mexico. Atlantic Tripletail can be found in Mississippi state waters in the warmer months of the year, which is when the species is widely believed to spawn. Atlantic Tripletail are not known to inhabit Mississippi state waters in the cooler months of the year, and little is known about their preferred habitat usage during that period. Gaining a better understanding of these migratory patterns will help MDMR Fisheries staff better manage this increasingly popular sport fish.
The satellite tags are programmed to record location, water temperature and depth readings for each fish through Spring 2020. Results from the satellite tags will be displayed as data arrives and is verified. If a tagged fish is caught, anglers are encouraged to release the tagged fish. However, no regulations prohibit the keeping of a legal tagged fish. Anglers are requested to report the location of the catch and the length of the fish. To report a tagged fish, please call the MDMR Sport Fish hotline number at 884-704-2359 or the MDMR office at 228-374-5000.
ASSESSMENT OF RED DRUM
The goal of this project is to provide data about age-3 to age-5 Red Drum in Mississippi coastal waters to better understand escapement rate, length-at-age, age-at-maturity and describe movement and habitat utilization at early life stages. Movement and habitat utilization are tracked by acoustic tags attached to juvenile, sub-adult and adult red drum inside and in proximity to the Back Bay of Biloxi. These acoustic tags are placed in the stomach cavity and set to send out signals every minute. A blue external dart tag is placed under the dorsal fin. The location of a tagged fish is recorded every time the fish swims in proximity of the acoustic receivers that make up the array.
The Mississippi Department of Marine Resources (MDMR) has tagged 45 Red Drum in Biloxi Bay. If a tagged fish is caught, anglers are encouraged to release the tagged fish. However, no regulations prohibit keeping a legal tagged fish. Anglers are requested to report the location of the catch and length of the fish. To report a tagged fish, please call the MDMR Sport Fish hotline number at 844-704-2359 or the MDMR office at 228-374-5000.
MISSISSIPPI COASTAL SPORT FISH STUDIES
This project provides scientific information necessary for sound management of selected recreational species occupying Mississippi coastal waters. The information obtained provides an assessment of population dynamics and an annual index of abundance for Spotted Seatrout, relative abundance and age structure of Red Drum, and abundance, distribution and movement data on coastal shark species. This project is led by the Gulf Coast Research Laboratory.
SPORT FISH TAG AND RELEASE
This study provides scientific information on important finfish species which support Mississippi’s economically important saltwater recreational fishery. Coordination with volunteer anglers allow for tagging large numbers of Cobia, Tripletail, Red Drum and Spotted Seatrout. The study contributes significantly to the understanding of the seasonal movements of those sport fishes. This project is led by the Gulf Coast Research Laboratory.
Anglers interested in tagging any of the target species should contact GCRL at 228-818-8818 or firstname.lastname@example.org to request the free tagging kits. The following link provides more detail on the tag and release program: gcrl.usm.edu/fisheries_center/docs/tag.release.program.2008.pdf.
MISSISSIPPI ARTIFICIAL REEF PROGRAM
This project works to enhance recreational fishing opportunities, recreational diving opportunities and improved habitat for targeted reef fish and inshore species. Artificial reefs provide productive habitat which, in turn, increases fish production and angler opportunities. Since the establishment of the program, 67 inshore reefs, 15 offshore reefs and eight rigs to reefs have been created to support important marine species.
