Sardine Fish: Omega-3 Fatty Acids and Habitat


The correct answer is option 'A', which states that statement 1 is correct while statement 2 is incorrect.


Statement 1: It contains omega-3 fatty acids, which promotes a healthy heart.


Explanation:



  • Sardine fish is known for its high content of omega-3 fatty acids, which are essential polyunsaturated fatty acids.

  • The omega-3 fatty acids found in sardine fish are specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

  • These fatty acids have been shown to have numerous health benefits, particularly in relation to heart health.

  • Omega-3 fatty acids help to reduce inflammation, lower triglyceride levels, and prevent the formation of blood clots.

  • Regular consumption of omega-3 fatty acids has been associated with a reduced risk of heart disease, stroke, and other cardiovascular conditions.

  • Therefore, statement 1 is correct as sardine fish contains omega-3 fatty acids that promote a healthy heart.



Statement 2: It is only found in freshwater lakes.


Explanation:



  • Statement 2 is incorrect as sardine fish is primarily found in saltwater environments, such as oceans and seas.

  • Sardines are small, silvery fish that are part of the herring family.

  • They are known for their abundance in the Mediterranean Sea, Atlantic Ocean, and other coastal regions.

  • Sardines are also commercially important as they are widely consumed and used for canning and processing into various products.

  • While there are freshwater fish species that resemble sardines in appearance, they are not true sardines.

  • True sardines belong to the Clupeidae family and are exclusively found in saltwater habitats.



Therefore, statement 2 is incorrect as sardine fish is not only found in freshwater lakes.


To summarize, statement 1 is correct as sardine fish contains omega-3 fatty acids that promote a healthy heart. However, statement 2 is incorrect as sardine fish is primarily found in saltwater environments and not limited to freshwater lakes.

Thousands of sardine fish have been surfacing near a beach in Goa for the past few days and experts said it’s a “rare” phenomenon known as ‘sardine run’.
  • Shoals of the marine species are fluttering in shallow waters along the coast at Keri-Terekhol, about 40 km from Panaji.
  • Reason: This marine event is “very rare” and it usually happens due to sudden changes in the temperature of sea surface water where sardines live.
  • A drop or rise in sea surface temperature can induce migration of sardines in higher numbers and sometimes they get trapped in shallow waters 
Key facts about Sardine fish
  • It belongs to the herring family, Clupeidae.
  • The name sardine can also refer to the common herring (Clupea harengus) and to other small herrings or herringlike fishes when canned in oil.
  • Habitat: They are found in saltwater oceans, seas, and other bodies of water throughout the world. 
  • Distribution: Found all over the world from the North Atlantic and Pacific Oceans to the Mediterranean Sea, the Indian Ocean, and the waters around South America.
  • These are small, silvery, elongated fishes with a single short dorsal fin, no lateral line, and no scales on the head.
