What Are Factors Affecting Commercial Fishing?
(Game-Style Answer Key)
Level 1: Basic Factors
Fish Stock Availability
Explanation: The health and abundance of fish populations determine how much can be harvested. Overfishing (e.g., catching species faster than they reproduce) crashes stocks.
Example: Squid fishing in the North Sea collapsed in the 1990s due to overharvesting.
Government Regulations
Explanation: Quotas, seasonal bans, and size limits are enforced to protect ecosystems.
Example: India’s "Mandovi Declaration" limits trawl fishing in coastal zones to prevent habitat damage.
Economic Factors
Explanation: Fuel costs, market demand, and price fluctuations influence profitability.
Example: Rising fuel prices in 2022 cut profits for small-scale Indonesian fishers.
Level 2: Advanced Factors
4. Climate Change
Explanation: Warming oceans shift fish migration patterns (e.g., Atlantic cod moving northward).
Example: coral reef degradation in India’s Lakshadweep Islands reduces fish biodiversity.
Technology & Equipment
Explanation: Advanced gear (e.g., sonar, drones) increases catch efficiency but risks bycatch.
Example: India’s "Smart渔船" project uses AI to reduce plastic waste in catches.
Socio-Cultural Factors
Explanation: Traditional practices and community rights impact fishing patterns.
Example: Andhra Pradesh’s "渔村合作社" empowers women to manage small-scale fisheries.
Level 3: Global Factors
7. International Agreements
Explanation: Treaties like the UN Fish Stocks Agreement manage transboundary species.
Example: The High Seas Treaty aims to protect unregulated oceans.
Environmental Pollution
Explanation: Plastic waste and chemical runoff (e.g., from agriculture) harm marine life.
Example: The Great Pacific Garbage Patch disrupts Pacific bluefin tuna migration.
Boss Battle: Overfishing vs. Sustainability
Key Conflict: Balancing profit with conservation.
Solution: Implementing EFishery apps (e.g., India’s "Fisheries Management System") to track stocks in real time.
Final Scorecard
Critical Factors: Stock health, regulations, climate, and tech.
Player Tip: Use data-driven tools (e.g., satellite monitoring) to avoid "fishing disasters."
