How to catch Blue-eye Trevalla

Blue-eye Trevalla is a species of deep-sea fish that is found in the waters around Australia and New Zealand. It is prized for its white, firm flesh and is often caught for commercial purposes. Here are the steps to catch Blue-eye Trevalla:

  1. Choose the right equipment: Blue-eye Trevalla is a deep-water species, so you will need a heavy-duty fishing rod and reel, and a strong fishing line.
  2. Identify the right location: Blue-eye Trevalla is typically found in deep waters around underwater canyons and drop-offs, so look for areas with these features.
  3. Select the right bait: Squid, pilchards, and cut bait are all effective baits for catching Blue-eye Trevalla.
  4. Cast your line: Cast your line into the water, making sure to reach the desired depth.
  5. Watch for bites: Pay attention to your line for any signs of a bite, such as a sudden pull or a change in the line's tension.
  6. Set the hook: When you feel a bite, quickly and firmly set the hook by pulling the rod back.
  7. Reel in the fish: Keep the rod tip up and reel in the line, being prepared for a fight as Blue-eye Trevalla are known to be a strong fighting species.
  8. Release the fish: If you're not planning to keep the fish for eating, gently remove the hook and release the fish back into the water.

Remember to follow fishing regulations and to always practice catch and release to ensure the health and sustainability of fish populations. It's also important to use appropriate fishing gear for the species you're targeting and to be aware of your surroundings, as fishing in deep waters can be dangerous.
