Worked Solution & Example Answer:The table of figures shows change over time in herring catches in part of the Celtic Sea off Ireland - Junior Cycle Geography - Question C - 2006
Step 1
To what extent does the table of figures show that fish stocks have been depleted over time in the seas off Ireland?
Answer
Between 1970 and 1998, the annual herring catch in the Celtic Sea decreased significantly. In 1970, the catch was 26,700 tonnes, while by 1998 it had declined to just 6,600 tonnes. This drastic reduction over nearly three decades indicates a severe depletion of fish stocks in this area. The trend shows that the average annual catch fluctuated but generally followed a downward trajectory, highlighting concerns about sustainability and the health of fish populations.
Step 2
Describe three reasons for the depletion of fish stocks in Irish waters.
Answer
-
Efficient Fishing Technology: Modern fishing boats equipped with radar and sonar technology have led to more effective capturing of fish. This has made it increasingly difficult for fish to escape, thereby reducing their populations.
-
Overfishing: Factory ships often spend extended periods at sea, leading to vast areas being overfished. This high intensity of fishing removes large quantities of fish from the ecosystem, preventing stocks from replenishing.
-
Increased Foreign Competition: The rise in foreign fishing fleets has intensified competition for fish resources. These fleets may exploit local stocks more aggressively, undermining sustainable practices and contributing to the depletion of fish populations in Irish waters.
