Technical Interview Questions
What are some modern fish harvesting methods and technologies, and how do they improve efficiency?
How to Answer
- 1
Identify key harvesting methods like aquaculture, purse seining, and longlining
- 2
Mention technologies like sonar, GPS, and automated systems
- 3
Discuss how these methods reduce time and increase catch quality
- 4
Highlight environmental sustainability and reduced bycatch
- 5

Example Answers
Modern fish harvesting methods like aquaculture, using controlled environments to raise fish, improve efficiency by maximizing growth rates and reducing reliance on wild stocks. Technologies like sonar assist in locating schools of fish, which increases catch rates and minimizes waste.
Can you describe key physiological differences between freshwater and marine fish that a fish technologist should be aware of?
How to Answer
- 1
Focus on osmoregulation differences between freshwater and marine species.
- 2
Mention differences in gill structure and function in relation to salinity.
- 3
Discuss adaptations to buoyancy for both types of fish.
- 4
