Biomass Estimation
Biomass Estimation is a way of measuring how many fish and their total weight are present in fish farms or aquaculture facilities. Think of it like taking inventory in a store, but for fish. This process helps fish farmers track fish growth, plan feeding schedules, and decide when to harvest. It's important because it affects business decisions like when to sell fish and how much feed to buy. Some farms use simple methods like visual counting and sampling, while others use advanced underwater cameras or sonar technology. This skill is essential for managing fish farms efficiently and profitably.

Example Interview Questions
Senior Level Questions
Q: How would you implement a biomass estimation system for a large salmon farm?
Expected Answer: A strong answer should cover planning regular sampling schedules, using appropriate technology (cameras/sensors), training staff, analyzing data trends, and making production recommendations based on findings.
Q: How do you handle discrepancies between estimated and actual biomass?
Expected Answer: Should discuss methods for investigating causes (like feed conversion rates, mortality rates), adjusting estimation methods, and implementing corrective measures to improve accuracy.
Mid Level Questions
Q: What factors affect biomass estimation accuracy?
Expected Answer: Should mention water clarity, fish behavior, equipment calibration, sampling methods, and environmental conditions like temperature and oxygen levels.
Q: How do you determine appropriate feeding rates based on biomass estimates?
Expected Answer: Should explain relationship between fish size, water temperature, and feed requirements, plus how to adjust feeding schedules based on regular biomass measurements.
Junior Level Questions
Q: What basic methods are used for estimating fish biomass?
Expected Answer: Should describe simple counting methods, weight sampling, and basic calculation of average weights times number of fish.
Q: Why is regular biomass estimation important in fish farming?
Expected Answer: Should explain its role in feed management, harvest planning, and monitoring fish health and growth rates.
