An MCQ Quiz About Fish Farming

The sentence states that fish farms not only affect the environment, but they may also harm communities. This suggests that there are potential negative consequences for humans as a result of fish farms. Therefore, the question that would best clarify the idea in the sentence is "What are the long-term effects of waste products from fish farms on humans?" as it directly addresses the potential harm to communities.

Salt water is used for mariculture because it closely resembles the natural habitat of marine organisms. Mariculture involves cultivating and breeding marine plants and animals in controlled environments such as ponds, tanks, or cages. Using salt water ensures that the conditions are suitable for the growth and development of these organisms, as they have evolved to thrive in saline environments. Chlorinated water and pure water are not suitable for mariculture as they do not provide the necessary salinity levels and essential minerals required for the survival of marine organisms.

The author's purpose for using headings is to organize the material so the passage is easier to follow. Headings help to break down the content into different sections, allowing readers to quickly locate specific information or navigate through the passage more efficiently. This makes it easier for readers to understand the main points and structure of the passage.

Fish farming, also known as aquaculture, involves raising fish in controlled environments. This industry has grown significantly in recent years to meet the increasing global demand for seafood. The given answer, 70%, suggests that fish farming has exploited a significant portion of the world's wild fish stock. This means that a large percentage of fish consumed worldwide comes from fish farms rather than being caught in the wild. This exploitation has both positive and negative implications, as it helps meet the demand for seafood but also puts pressure on natural fish populations and ecosystems.

Based on the information in the passage, a reader can infer that with careful regulation, fish farming could help preserve our natural resources. This can be inferred because the passage mentions that fish farming is on the rise, indicating its increasing popularity and demand. By regulating fish farming practices, it can be ensured that it is done sustainably and does not deplete natural resources. Therefore, careful regulation can help preserve our natural resources while meeting the demand for seafood.

The sentence "The two forms of aquaculture are extensive and intensive; both of these methods are actively helping ease pressure on overfished bodies of water." best summarizes the section entitled "What Is Aquaculture?" because it provides a clear and concise explanation of the two forms of aquaculture and their purpose of alleviating pressure on overfished bodies of water.

Goldfish have been cultivated using aquaculture techniques since 800 AD. This suggests that the practice of breeding and raising goldfish in controlled environments has been ongoing for over a thousand years. It demonstrates the long history and cultural significance of goldfish as a domesticated species.

Fish farming systems can be categorized into three main types: extensive, semi-intensive, and intensive systems. Extensive systems involve low stocking densities and minimal human intervention, while semi-intensive systems involve moderate stocking densities and some level of management. Intensive systems, on the other hand, involve high stocking densities and require significant management and input of resources. Therefore, the correct answer is 3.

Salmon, carp, and catfish are raised by fish farms. Fish farms are facilities where fish are bred, raised, and harvested in controlled environments. These three species are commonly raised in fish farms due to their high demand in the market, ability to adapt to captivity, and ease of breeding. Starfish, on the other hand, are not typically raised in fish farms as they have different requirements for survival and are not commonly consumed as food.
