Knowing when fish is cooked on the grill is crucial to avoid overcooking, which can result in a dry and tough texture. One common method to check if fish is cooked is by using a fork to gently twist and lift a corner of the fish. If the flesh easily flakes apart and appears opaque all the way through, it is done. Another way is to use a meat thermometer inserted into the thickest part of the fish. The internal temperature should reach 145°F (63°C) for most fish varieties. Additionally, you can observe the color change of the fish from translucent to opaque as it cooks. Overcooking fish can happen quickly, so it's essential to monitor it closely while grilling.
