This set of Marine Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Aquaculture and Mariculture – Set 4”.
1. _______________ is the first step in aquaculture risk analysis.
a) Hazard identification
b) Risk assessment
c) Risk management
d) Risk communication
View Answer
Explanation: There are four major kinds of activities in an aquaculture risk analysis process. Activities include hazard identification – the first step through risk communication using the feedback mechanism.
2. The risk matrix contains _____________
a) significance, quantity
b) likelihood, significance
c) impact, significance
d) likelihood, impact
View Answer
Explanation: The risk matrix is used to analyze the potential risks associated with certain factors, this method is a part of risk management in aquaculture. A matrix containing impact on the x-axis and likelihood on the y-axis is formulated.
3. The fault tree method is used for hazard identification.
a) True
b) False
View Answer
Explanation: Fault tree is a robust method used for hazard identification applied to estimate hazards from invasive species. The method has been used to investigate the hazard of introducing GIFT Tilapia in Zambia.
4. Zoonotic pathogens are identified as hazards in the food safety of aquaculture products.
a) True
b) False
View Answer
Explanation: The risk analysis consists of hazards identification, risk assessment, risk management and risk communication. For food safety zoonotic pathogens and chemicals of clinical importance are identified as hazards.
5. AquaFRAM is a ____________
a) spreadsheet tool
b) matrix
c) windows application
d) electronic probe
View Answer
Explanation: AquaFRAM is a spreadsheet tool used to estimate food safety and disease risk in aquacultured salmon. Genetic risks in aquaculture are associated with introgression between cultured species and wild stock.
6. The MSC marked fish is _______________
a) pathogen-free
b) hybrid
c) freshwater
d) sustainably produced
View Answer
Explanation: The MSC – Marine Stewardship Council is an independent non-profit organization that sets standard for sustainable fishing. A fish that has got MSC mark associated with it means that it is produced sustainably.
7. The full form of EAA is _______________
a) Economic Agriculture Aquaculture
b) Exclusive Appropriate Aquaculture
c) Extensive Agriculture-integrated Aquaculture
d) Ecosystem Approach to Aquaculture
View Answer
Explanation: A strategy was proposed by Food and Drug Organization in 2010 that was aimed at blending aquaculture in the wider ecosystem dubbed as the EAA – Ecosystem Approach to Aquaculture.
8. The inputs for MOM model used for estimation of environmental carrying capacity are ________________
a) waste dispersion
b) heat dispersion
c) physical environment
d) clearance rate
View Answer
Explanation: MOM (modeling ongrowing fish farms-monitoring) is a model used to estimate environmental carrying capacity associated with the setting up of an aquaculture system. The inputs (criteria for the model) are waste dispersion and waste dilution.
9. Which model is used for assessment of benthic environment?
a) CORMIX
b) Ecopath
c) Shellsim
d) BEAST
View Answer
Explanation: BEAST – benthic environmental assessment sediment tool takes sediments, particle size, and erosion as the input criteria and predicts the environment carrying capacity of the aquaculture system.
