The Fish and Wildlife Research Institute (FWRI), in partnership
with Mote Marine Laboratory (MML), is in the midst of a large-scale
redfish (red drum) stock enhancement project in Tampa Bay.
The goal of Project Tampa Bay is to increase the number of red
drum caught by anglers in Tampa Bay and to experimentally determine
the best sizes and locations for stocking in order to meet that
goal in the most cost-effective manner. Before this project began,
an in depth process was designed and implemented by scientists to
identify and prioritize potential candidate stock enhancement
species and stocking location. The process included a survey of
many salt water fishing license holders, which recognized red drum, common snook and seatrout as
the top three species. After a careful evaluation using a variety
of criteria, scientists selected redfish as the species of choice
for stocking Tampa Bay.
Tampa Bay was selected as the pilot stock enhancement site for
several reasons. First, it already has an existing red drum fishery
as well as an abundance of red drum nursery habitat. Our marine
hatchery, called the Stock
Enhancement Research Facility (SERF), is located near the shore
of Tampa Bay in northwest Manatee County and has been culturing red
drum since it opened in April 1988. Also, the FWRI Fisheries
Independent Monitoring (FIM) program currently monitors wild fish
populations in Tampa Bay and many of its contributing river
systems.
The Alafia River is the primary study area and the Little
Manatee River is a secondary release area for Project Tampa Bay.
These rivers were selected because the majority of juvenile red
drum documented in Tampa Bay by FIM monitoring teams over the past
ten years were captured within these two river systems. FIM's
monitoring efforts will provide data on the abundance of red drum
in these locations before and after hatchery fish are stocked. This
information is important for assessing the effect on the ecosystem
as well as determining what size fish is most cost-effective to
raise.
The staff at SERF began raising red drum
for Project Tampa Bay in August 1999 using fertilized eggs provided
by the Florida Power Crystal River Mariculture Facility. Stocking
began in the spring of 2000 and completed in December
2004. Stocking occured in the Alafia and Little Manatee
River Systems. Because our goal is to increase the number of red
drum caught, it is important to stock fish where many people
already fish for them. Anglers can help track these fish by
reporting capture information on any red drum caught in Tampa Bay
and by cooperating with scientists conducting creel surveys.
We believe that stocking hatchery fish, if done responsibly, can
be a cost-effective addition to fisheries management tools such as
regulations and habitat protection. It is believed that hatchery
raised fish can be used to restore populations that have been
depleted by man-made or natural disasters such as chemical spills
or freezes and to supplement weak year classes. If hatchery fish
can substantially enhance wild populations, increased bag limits
for anglers may be justified.
