1. A recirculating aquaculture system (RAS) experiences a sudden increase in
nitrite levels while ammonia remains stable. What is the most likely
explanation?
A. Failure of ammonia-producing bacteria
B. Partial disruption of nitrite-oxidizing bacteria populations
C. Excess dissolved oxygen
D. Reduced feeding activity
Answer: B
Rationale: Nitrite accumulation commonly occurs when nitrite-oxidizing bacteria
are impaired while ammonia conversion continues.
2. A facility records repeated dissolved oxygen crashes shortly before dawn
despite functioning aerators. What should be evaluated first?
A. Nighttime biological oxygen demand and stocking density
B. Parking lot drainage
C. Feed packaging labels
D. Pond shape alone
Answer: A
Rationale: High biological demand can overwhelm available aeration capacity
during nighttime hours.
3. Which BMP principle best supports early disease detection?
,A. Routine observation and health monitoring
B. Increased stocking density
C. Reduced recordkeeping
D. Eliminating inspections
Answer: A
Rationale: Frequent monitoring allows problems to be identified before significant
losses occur.
4. A farm manager notices fish congregating near water inlets during warm
afternoons. What condition should be suspected first?
A. Elevated dissolved oxygen levels
B. Localized oxygen stress in production areas
C. Excess alkalinity
D. Excess feed availability
Answer: B
Rationale: Fish often seek areas with better oxygen conditions during periods of
stress.
5. What is the primary BMP objective when managing broodstock populations?
A. Maintain genetic quality and reproductive performance
B. Maximize stocking density only
C. Reduce recordkeeping
D. Eliminate health monitoring
Answer: A
Rationale: Broodstock management directly influences long-term production
success.
6. A facility experiences increasing feed conversion ratios despite stable water
quality. What should be investigated next?
A. Feed quality and fish health status
B. Facility landscaping
C. Parking availability
D. Harvest equipment color
, Answer: A
Rationale: Poor feed quality and health problems commonly reduce feed
efficiency.
7. Which BMP practice most effectively minimizes cross-contamination between
ponds?
A. Dedicated equipment and disinfection procedures
B. Shared nets among all ponds
C. Unrestricted movement between units
D. Eliminating sanitation stations
Answer: A
Rationale: Dedicated equipment reduces pathogen transfer risks.
8. What is the greatest environmental concern associated with excessive
phosphorus discharge?
A. Eutrophication and algal blooms
B. Reduced plant growth
C. Increased oxygen levels
D. Lower biological activity
Answer: A
Rationale: Phosphorus is a major contributor to nutrient enrichment.
9. A pond's pH fluctuates dramatically between sunrise and afternoon. What is
the most likely cause?
A. Active phytoplankton photosynthesis and respiration cycles
B. Mechanical aeration failure only
C. Feed storage problems
D. Equipment corrosion
Answer: A
Rationale: Photosynthesis and respiration strongly influence daily pH changes.
10. Which BMP strategy best reduces the likelihood of catastrophic fish losses
during power outages?
