The IELTS Reading section is designed to evaluate a test taker’s ability to understand and interpret English texts. One common and significant topic featured in IELTS reading passages is environmental issues, such as the consequences of overfishing on marine ecosystems. Such topics have become increasingly relevant, given the global concerns about sustainability and biodiversity.
In this article, we’ll create a detailed Reading practice passage and questions centered on the theme “What are the consequences of overfishing on marine ecosystems?”. The practice material will resemble actual IELTS exam content, providing a realistic preparation experience.
Mock IELTS Reading Passage: Consequences of Overfishing on Marine Ecosystems
Reading Passage
The sustainable management of marine resources is critical for maintaining environmental balance. Overfishing, which entails catching fish at rates faster than they can reproduce, has led to significant ecological imbalances, impacting marine ecosystems on multiple levels.
Depletion of Fish Populations
The most immediate consequence of overfishing is the dramatic decline in fish populations. Species such as the Atlantic cod have seen their numbers dwindle to critically low levels due to excessive fishing practices. This depletion affects not only the targeted species but also disrupts the entire marine food chain.
Impact on Biodiversity
Marine biodiversity suffers considerably as a result of overfishing. Predatory fish, like sharks and tunas, face heightened risks due to their slow reproductive rates. As these top predators are removed from the ecosystem, there is an overpopulation of smaller fish species, which further destabilizes marine habitats.
Destruction of Marine Habitats
Overfishing often leads to habitat destruction, particularly through practices like trawling that scrape the ocean floor. Coral reefs, which serve as crucial breeding and feeding grounds, are especially vulnerable. The loss of these important habitats compromises the health of the marine environment and the services it provides.
Economic and Social Consequences
Communities reliant on fishing face dire economic consequences due to overfishing. Reduced fish stocks lead to diminished catches and, consequently, lower incomes for fishermen. This situation creates a vicious cycle, pushing fishers to exert even greater pressure on already depleted stocks to sustain their livelihoods.
Mitigation Strategies
Efforts to mitigate the impacts of overfishing include establishing marine protected areas (MPAs), implementing catch quotas, and promoting sustainable fishing practices. These strategies aim to give fish populations a chance to recover and help maintain the balance of marine ecosystems.

Answer Key and Explanations
-
- A: Depletion of Fish Populations
- B: Impact on Biodiversity
- C: Destruction of Marine Habitats
- D: Economic and Social Consequences
- E: Mitigation Strategies
-
No. The passage states that depletion affects the entire food chain, not just targeted species.
-
Not Given. The passage mentions critically low population levels but does not confirm extinctions.
-
Yes. It is stated that coral reefs serve as breeding grounds, and their loss affects fish breeding.
-
smaller fish species
-
Depletion, food chain
Common Mistakes to Avoid
- Misinterpreting the scope of the impact (e.g., assuming it affects only one species).
- Overgeneralizing statements not supported by the text (e.g., claiming species extinction without confirmation).
Vocabulary
- Biodiversity (noun) /ˌbaɪ.əʊ.dɪˈvɜː.sɪ.ti/: The variety of life in the world or in a particular habitat.
- Trawling (verb) /ˈtrɔː.lɪŋ/: Fishing method that involves dragging a net across the sea bed.
- Quotas (noun) /ˈkwəʊ.təz/: A limited or fixed number or amount of people or things.
Grammar Focus
- Use of present simple for general truths (e.g., Overfishing often leads to habitat destruction).
- Relative clauses to provide additional information (e.g., Coral reefs, which serve as crucial breeding and feeding grounds, are especially vulnerable).
Advice for High Reading Scores in IELTS
