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’.
About 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

Q1) What are omega-3 fatty acids?
Omega-3 fatty acids (omega-3s) are polyunsaturated fats that perform important functions in your body. Your body can’t produce the amount of omega-3s you need to survive. So, omega-3 fatty acids are essential nutrients, meaning you need to get them from the foods you eat.
