Place about ¼ cup olive oil in a medium sized pot over medium high heat. There should be about ½ inch of oil in the pot.
Sprinkle the pieces of fish with salt. Place flour into a small bowl. Dip a piece of fish in the flour and shake off any excess flour. Dip the fish into the oil, if it sizzles vigorously, the oil is ready for frying. Place the piece of fish into the oil and continue the process with another 4 to 6 pieces of fish. Fry the fish on each side until golden brown, about 2 minutes on each side. Transfer the fish onto a paper towel lined plate to drain any excess oil. Continue frying the rest of the fish in batches.
Place the vinegar, olive oil, onion, and cilantro into a deep mixing bowl or container. Mix to combine all the ingredients well. Place all the fried fish into the bowl and make sure all the pieces of fish are submerged in the liquid. Seal the bowl with plastic wrap and set it aside for at least 2 hours before serving. The escabeche can marinate up to 8 hours, overnight, as long a it is stored in the refrigerator.
Serve the escabeche at room temperature.
