Worked Solution & Example Answer:Fishing (i) Explain two reasons for the over-exploitation of fish - Junior Cycle Geography - Question B - 2017
Step 1
Explain two reasons for the over-exploitation of fish.
Answer
-
Use of Advanced Technology: The rise of modern fishing technology, such as sonar and GPS, has significantly increased the efficiency of locating and catching fish. These advancements allow fishermen to target specific species and locate them in greater quantities, often leading to overfishing of certain stocks.
-
Increased Demand for Fish: The global demand for fish has steadily risen due to population growth and dietary changes. This heightened demand often results in unsustainable fishing practices, as fishers aim to meet market needs without regard for ecological balance.
Step 2
Describe two measures that are used to prevent the over-exploitation of fish.
Answer
-
Implementation of Quotas: Many countries and organizations establish fishing quotas that limit the amount of specific fish species that can be caught within a certain timeframe. These quotas help to ensure that fish populations can replenish, reducing the risk of over-exploitation.
-
Protection of Fishing Vessels: Regulations can be put in place to monitor and protect fishing vessels, ensuring they comply with sustainable fishing practices. This might include restrictions on the use of particular nets or the establishment of marine protected areas where fishing is limited or banned.
