Harvesting — Quiz
Test your understanding of harvesting with 5 practice questions.
Practice Questions
Question 1
A university aquaculture course is discussing harvest timing. Which of the following biological indicators is the most reliable for determining the optimal harvest point for finfish to maximize economic return and product quality?
Question 2
In the context of harvesting methods for bivalve shellfish, a farm is considering two options: manual harvesting by divers versus mechanical dredging. Assuming both methods are feasible for the specific farm site, which of the following factors is the most significant economic consideration when choosing between these two methods?
Question 3
A shellfish depuration facility is designed to remove pathogenic microorganisms from oysters. The system uses a continuous flow of UV-sterilized seawater. If the flow rate of the seawater is significantly reduced below the recommended level, what is the most direct and critical consequence on the effectiveness of the depuration process?
Question 4
A finfish aquaculture operation is implementing a new humane handling protocol during harvest. The protocol includes a step for 'percussive stunning' before bleeding. What is the primary physiological mechanism by which percussive stunning achieves its humane objective?
Question 5
A land-based recirculating aquaculture system (RAS) is harvesting a batch of tilapia. The fish are crowded into a harvest tank, then pumped to a processing area. To minimize post-harvest stress and maintain flesh quality, which of the following environmental parameters in the harvest tank is most critical to monitor and control during the crowding phase?
