Tips For Safely
Releasing Adult Red Drum
The increasing popularity of
recreational fishing in S.C.
demands effective conservation practices to ensure healthy
fish populations. When fishing for adult red drum in coastal
waters, important steps taken can minimize fishing mortality
after a prized catch.
The current regulations for red drum are such that
anglers can catch no more than 3 per person per day, at a
size of 15 inches total length or greater and equal to or
less than 23 inches total length maximum. After red drum
grow and reach sexual maturity, by age 4, they join the
spawning population found in coastal waters, grow very
slowly and reach 25 to 50 pounds in weight. Most adult red
drum that are caught fall outside of the legal parameters
for keeping this species, and anglers, either through legal
requirement or fishing preference, release these large fish
back into the water.
Recently, S.C. Department of Natural Resources (DNR)
has received reports of adult fish caught in deep water in
coastal inlets floating at the surface after being
released. Coming up from greater depths inflates the air
bladder and puts the fish in peril until the bladder purges
air allowing the fish to swim normally.
When releasing the fish back into the water, doing so
headfirst helps to expel this excess air. A fish that has
been stressed can be revived by gently moving it forward to
promote water flow over the gills. Once their tail enters
the water, typically they have enough propulsion they need
to survive and reach the greater depths again. Some anglers
are trained in a technique called venting, which involves
releasing the gas from an over-inflated swim bladder with a
hollow, sharpened steel-venting tool. This technique
effectively releases pressure and allows the fish to
overcome buoyancy problems. Anglers wishing to be trained in
proper venting techniques should contact DNR at (843)
953-9300.
Using appropriate fishing tackle, practicing
safe-handling techniques and carefully releasing the fish
back into the water are helpful steps that can minimize
mortality after these large fish have been released. DNR
biologists have conducted important catch and release
studies on the recreationally important red drum. The
research provides insight on most effective tackle to use to
minimize mortality of a fish. For additional information

DNR biologists found through this research that
fishing with non-offset circle hooks was the most efficient
and effective type of hook to use to minimize mortality of
the fish after it is released. With over 95% of the adult
red drum caught using circle hooks during this study, the
hooks were set in the mouth or lips. Because of their unique
design, circle hooks almost always hook fish in the mouth,
whereas other hooks are more likely to hook fish in the gut
or gills. Fish hooked in the gut or gills will often die of
internal injuries to vital organs that are sustained during
capture.
Additionally, DNR suggests that the practice of using
heavier test line can reduce landing time and assist with the
safe release of adult red drum back into the water.
Appropriate tackle for minimizing adult red drum mortality
following release is at least a 20-pound test line and a
medium weight rod. Using light fishing tackle and fighting
the fish on the line for an extended period of time can
stress the fish and increase the chance of death once
released back into the water. This is especially important
during the summer months when water temperatures are at their
maximum.
If removed from the water, returning the fish as
quickly as possible minimizes stress and damage that may
incur. It is best not to remove the fish from the water when
possible, to reduce the chance of mortality. |
