1. Which of the following is considered a primary goal of aquatic
pest management?
A. Increase recreational fishing revenue
B. Control invasive species and maintain ecosystem balance
C. Reduce rainfall runoff
D. Promote the growth of all aquatic plants
B
Rationale: Aquatic pest management aims to control invasive
species, prevent damage to ecosystems, and maintain healthy
aquatic habitats rather than simply promoting growth or
economic benefits.
2. The most common invasive aquatic plant in Connecticut waters is:
A. Eurasian watermilfoil
, B. Cattail
C. Water lily
D. Duckweed
A
Rationale: Eurasian watermilfoil is widespread in Connecticut and
poses ecological and recreational challenges due to its rapid
growth and dense mats.
3. Which of the following is a common method for controlling
submerged aquatic vegetation?
A. Mechanical harvesting
B. Burning
C. Soil tilling
D. Crop rotation
A
Rationale: Mechanical harvesting removes invasive plants from
water bodies. Burning and soil tilling are not suitable for aquatic
environments, and crop rotation applies to agriculture.
4. What is the primary purpose of herbicide application in aquatic
environments?
A. Kill fish populations
B. Eliminate all plant life
, C. Control or manage problematic aquatic plants
D. Alter water pH
C
Rationale: Aquatic herbicides target nuisance plants while
minimizing harm to non-target species and overall ecosystem
health.
5. Which factor most affects herbicide effectiveness in aquatic
systems?
A. Water temperature
B. Cloud cover
C. Air humidity
D. Wind speed
A
Rationale: Water temperature influences herbicide uptake by
plants; cooler water slows absorption and activity.
6. When applying aquatic pesticides, the first step in site assessment
should be:
A. Applying the chemical immediately
B. Identifying the target species and its location
C. Calculating fishing quotas
D. Shading the area with tarps
, B
Rationale: Proper site assessment ensures accurate identification
of target species and selection of appropriate control methods,
reducing environmental risks.
7. Which of the following best describes “contact” herbicides?
A. They move systemically through the plant
B. They only affect the area they touch
C. They promote plant growth
D. They alter water chemistry permanently
B
Rationale: Contact herbicides kill plant tissue where they directly
contact but do not move through the plant system.
8. Systemic aquatic herbicides are most effective on:
A. Surface algae only
B. Entire plants, including roots
C. Floating debris
D. Fish populations
B
Rationale: Systemic herbicides are absorbed and translocated to
roots and other plant parts, making them effective for perennial
and deep-rooted species.
