Tournament Guidelines Fishing competitively for black
bass in New Hampshire has intensified substantially over the
last decade. With this in mind, it has become increasingly important
for bass tournament
sponsors and participants to keep the following in mind, in an
effort to minimize potential conflicts with other user groups and
to maximize the survival of bass that are caught and subsequently
released during the event.
1. It is the responsibility of the bass tournament sponsors to
contact and comply with all local requirements governing the use
of municipal and town owned boat launch facilities and parking
areas. The local contact should include town officials (Selectman/Town
Manager) and the Police Department.
2. Show consideration at all times at the launch ramp by alternating
the launching and retrieving of boats with other boaters, allowing
equal access to the ramp.
3. KEEP YOUR LIVEWELL FULL! Excessive sloshing over an extended
period of time during rough-water rides, especially in a less-than-full
livewell, may lead to injuries to bass from contact with aerator
components, dividers, or compartment lids.
4. Water temperature tolerance for bass
depends on the temperature to which it is acclimated. Fish living
in 65º water cannot
tolerate warmer water temperatures (>78º) as well as fish
living in 75º water. A rapid temperature increase of 5º or
a rapid temperature decrease of 10º can be lethal to bass.
5. Bass metabolism increases rapidly as
water temperatures go up – meaning bass need more oxygen, consume it more rapidly,
at a time when the water’s ability to hold more oxygen is
declining. Therefore it takes more aeration of the livewell water
to keep bass alive at warmer temperatures.
6. Livewell water quality constantly changes during the tournament
day as bass excrete metabolic waste in the form of ammonia, which
is highly toxic to the fish with the toxicity increasing with water
temperature. The build up of ammonia is easily resolved by continuous
pumping of fresh water into the livewell.
7. Stress is a major cause of delayed mortality in tournament
caught bass. Reducing stress to these bass requires three things:
reducing handling injuries and loss of protective mucus; healthy
conditions in the boat livewell; and, quick, efficient weigh-ins
where fish are subjected to minimal handling while maintained in
adequate life-supporting conditions through-out the weigh-in process.
8. Some procedures to expedite fish release
(and thus reduce initial mortality) include: staggering start
and weigh-in times, having
shaded holding tanks with flow through circulation systems available
at the weigh-in, not holding weigh-ins when air temperatures are > 90°F,
and transporting fish from live-well to weigh-in in water-filled
plastic bags (the time fish remain in water-filled plastic bags
should be less than 10 minutes).
9. Studies have found larger black bass experience greater initial
mortality than smaller black bass, indicating capture and confinement
in live-wells appears to be especially stressful to larger fish.
It is essential that losses of large black bass in northern populations
are minimized since larger males and females spawn earlier in the
spring, allowing the resulting progeny to accumulate more energy
reserves prior to entering their first wintering period, which
increases their chance for survival. Tournament organizers can
address this issue by adopting big fish or big fish/hour formats
that reduce the time large bass are held in live-wells before weigh-in
and release.
10. Initial mortality has also been positively related to daily
limit, and mean weight and number of fish per angler. Additionally,
it has been shown that the daily limit is the single most influential
variable affecting initial mortality. Tournament organizers can
address this concern by implementing reduced daily limits.
