Section B: Fishery Theory Questions (Continued)

 

Question: Explain the concept of the Exclusive Economic Zone (EEZ) and its role in fisheries management.

 

Answer: The Exclusive Economic Zone (EEZ) is an area extending 200 nautical miles from a country’s coastline, giving that nation exclusive rights to exploit and manage marine resources within this zone. It plays a crucial role in regulating and managing fisheries for sustainable use.

 

Question: Discuss the importance of traceability in seafood supply chains and its impact on combating illegal, unreported, and unregulated (IUU) fishing.

 

Answer: Traceability in seafood supply chains involves tracking the journey of fish from catch to consumption. It helps combat IUU fishing by ensuring transparency, verifying legality, and holding actors accountable throughout the supply chain.

 

Question: Describe the concept of bycatch reduction devices and their role in promoting sustainable fishing practices.

 

Answer: Bycatch reduction devices are tools or modifications to fishing gear designed to minimize the unintentional capture of non-target species. They play a crucial role in promoting sustainable fishing practices by reducing the ecological impact of bycatch.

 

Question: Discuss the potential socio-economic impacts of overfishing on fishing communities.

 

Answer: Overfishing can lead to reduced fish stocks, impacting the income and livelihoods of fishing communities. It may result in economic challenges, unemployment, and migration, emphasizing the need for sustainable fisheries management to support these communities.

 

Question: Explain the concept of Integrated Multi-Trophic Aquaculture (IMTA) and its benefits in aquaculture sustainability.

 

Answer: Integrated Multi-Trophic Aquaculture (IMTA) involves cultivating multiple species in proximity, where the waste from one species serves as nutrients for another. This practice enhances nutrient cycling, reduces environmental impact, and promotes sustainability in aquaculture.
