b. Conservation and Coexistence

  1. Responsible Fishing Practices: Implement and support sustainable and responsible fishing practices to minimize the attraction of sharks to human activities.
  2. Educational Programs: Promote public awareness and education about shark behavior, dispelling myths and fostering coexistence.

Common Misconceptions about Sharks Near Shore

a. Sharks Only Live in Deep Water

  • While some species prefer deeper offshore waters, many sharks inhabit a wide range of depths, including coastal areas and shallow waters.

b. Sharks Are Always Dangerous Near Shore

  • The presence of sharks near shore does not inherently imply danger. Most shark species are not a threat to humans, and incidents are rare.

c. Sharks Hunt Humans Near Shore

  • Sharks primarily prey on marine animals and are not actively seeking humans as food. Incidents involving humans are often cases of mistaken identity.

d. Avoiding Sharks by Staying in Shallow Water

  • Shallow waters do not guarantee safety, as sharks are capable of entering these areas. Safety measures should be applied regardless of water depth.
