What Temperature Is Fish Done: Signs It’s Done

Knowing when your fish is done cooking is an essential part of making a delicious meal.

Undercooking can result in under-seasoned, raw fish, and over-cooking can lead to dry, overcooked meals. But how do you know exactly when fish is “done”?

Fish can be smoked safely for eating at temperatures between 150 and 200 degrees Fahrenheit for around two to five hours or until the internal temperature reaches 145 degrees Fahrenheit (or 62.7 degrees Celsius).

In this blog post, we’ll break down the different types of techniques that you can use to tell if your fish has reached the optimal temperature and texture for a perfect meal every time!

Read on to discover all of the tips and tricks you need to find out what temperature is best for serving up a flavorful dish that everyone will love.

How To Tell When Fish Is Done?

The two methods for determining whether your fish is cooked are visual cues that do not require any special equipment or thermometers.

These cues will appear when the fish has reached the food preparation temperature and is fully cooked. 

  • The color is opaque. When you first start cooking fish, it is quite shiny and translucent. When finished, the fish will be translucent. 
  • Flake easily with a fork. When fish is finished cooking, it’ll flake apart with a fork (more on that next). It should flake easily without any pushing or tugging. Fish will firm up as it cooks.

Undercooked fish resists flaking and is translucent.

If your fish is undercooked, continue heating it until it’s done. But remember, fish cooks, fast, so be sure to check it often.

How To Tell When Smoked Fish Is Done?

One of the most difficult parts of smoking fish is knowing when it’s done.

If you cook it too long, the fish can become dry and unappetizing. If you don’t cook it enough, the fish won’t be safe to eat. 

Fortunately, there are some basic signs you can look for that can help you tell when your smoked fish is perfectly cooked.

The best indicator of doneness is the texture — if your smoked fish flakes easily with a fork, it is fully cooked and safe to eat. 

Additionally, you should also check for changes in color — when sufficiently smoked, the fish’s flesh will turn from its natural shade to a darker color with a slightly glossy finish. 

Finally, ensure that any internal cavities are cooked all the way through by running a food thermometer through them — for large types of fish like salmon, this should register at least 145°F to be considered done. 

By keeping an eye out for these key indicators, you’ll be able to know exactly when your smoked fish is done and ready to enjoy!

How To Smoke Fish?

1- Choose Your Fish.

The type of fish you choose to smoke will largely depend on personal preference.

Some of the most popular types of smoked fish include salmon, trout, and whitefish.

2- Prepare The Fish.

Once you have chosen your fish, you will need to prepare it for smoking.

This typically involves cleaning the fish and then removing the scales, guts, and gills.

You may also want to cut the fish into smaller pieces if you are smoking a large fish such as a salmon.

3- Dry Rub Or Seasoning

Once your fish is prepared, you will need to apply a dry rub or seasoning.

This can be as simple as salt and pepper, or you can get creative with different seasonings for a more flavorful finish.

4- Choose Your Wood Chips.

The type of wood chips you use will also affect the flavor of your smoked fish.

Popular choices include hickory, apple, and cherry. Avoid using pine or cedar, as these can give the fish an unpleasant flavor.

5- Soak The Wood Chips.

Soak the wood chips in water for at least 30 minutes before using them.

This will help to prevent them from burning up too quickly when you add them to the smoker.

6- Preheat The Smoker.

Preheat your smoker to a temperature between 200 and 250 degrees Fahrenheit before adding the fish.

There are two different methods for smoking your fish.

The first is the cold-smoking method, which is typically used for larger pieces of fish like salmon. 

This involves smoking your fish at a lower temperature (around 90 degrees Fahrenheit) for several hours until it is done.

The second method is hot-smoking, which can be used with smaller pieces of fish such as trout.

Place the prepared fish onto the racks in the smoker and close the lid.

Smoke the fish for 2-3 hours or until it reaches an internal temperature of 145 degrees Fahrenheit.

7- Check The Doneness.

Once the fish has been smoked for the recommended amount of time, check to see if it is cooked through.

Insert a food thermometer into the thickest part of the fish and ensure that it registers at least 145 degrees Fahrenheit before removing it from heat.

If not, continue cooking until it reaches this temperature.

6- Remove The Fish From The Smoker

Once the fish is fully cooked, remove it from the smoker and enjoy!

How To Test If The Fish Is Done?

Test If The Fish Is Done

Testing if your fish is done can be a tricky task, but with the right method, it’d be super easy and foolproof.

To do this, you should use the “poke test”.

Insert a fork into the thickest area of the fish, then twist to see if the flesh flakes easily. 

If your fish is done cooking, the flesh should flake away easily and it’ll be opaque in appearance.

If you’re still unsure, insert a thermometer into the center of it to make sure that there’s an internal temperature of at least 145°F for safety reasons. 

It’s important to remember that over-cooking or undercooking your fish won’t just impact its flavor but also its texture. 

What Temperature Is Fish Done In The Oven?

When it comes to the proper cooking of fish in the oven, the temperature you need to achieve a perfect end result is important. 

If it’s too low, fish will be undercooked or even outright raw, while if it’s too high, the texture and flavor of the fillet can suffer.

Generally speaking, the ideal oven temperature for most types of fish, such as whitefish and salmon, is 350°F (177°C).

Heavier fishes like cod or mahimahi also benefit from this higher temperature.

Nevertheless, depending on your recipe and variety of fish, roasting times may vary significantly – for instance, ocean-caught tuna should be roasted at 425°F (218°C). 

Experimenting with temperature is part and parcel of becoming a great cook – not only does it give an insight into the flavorsome diversity of seafood, but also ensures food safety.

What Temperature Is Fish Done On The Grill?

When it comes to grilling fish, there’s a sweet spot you want to hit on the thermometer.

The safest temperature range to cook your fish on the grill is between 145°F – 160°F. 

If the internal temperature of your fish registers below 145°F, then your seafood may still contain pathogens that can make you sick.

On the flip side, if cooked above 160°F, your fish will be dry and overcooked. 

To ensure you get perfectly cooked fish every time, use a food thermometer when grilling so that you can easily see when it reaches its peak temperature.

Trust us, and you won’t regret investing in one!

What Is Cod Cooked Temp?

Cod has a fat content of only 0.5%, making it an exceedingly lean fish; therefore, care must be taken when cooking it so as not to dry it out. 

The inner temp of smoked cod is perfect when it reaches 140 degrees Fahrenheit (or 60 degrees Celsius).

The fish will become drier if the pull is performed at a greater temperature.

What Is Halibut Done Temp?

The interior temperature of halibut that is cooked to perfection is between 130 and 135 degrees Fahrenheit (or 54.4 and 57.2 degrees Celsius).

Because it has a very low amount of fat, it has a tendency to dry up extremely quickly, and the thin and flaky muscle can come off quite easily. 

Temperatures in the region of 125 degrees Fahrenheit are ideal for those who prefer their meat cooked to medium-rare doneness.

To make it safe for human eating, the cooking time needs to be increased.

If you are smoking fish with a low amount of fat, such as halibut or cod, you should always apply a generous coating of oil (ideally extra virgin olive oil) to the surface of the fish before smoking it.

What Is Shrimp Cooked Temp?

When preparing shrimp for whatever cooking method is preferred by the cook, the internal temperature should reach an average of about 225 degrees Fahrenheit for at least 30-45 minutes.

For the shrimp to be completely done, the internal temperature should be 165 degrees Fahrenheit (or 73.9 ℃). 

This can be tested using a food thermometer easily inserted into the thickest portion of the shrimp flesh. 

Alternatively, some visuals like the shrimp turning from an opaque color to an opaque pinkish-white can be used a guideline for when the shrimp may be done cooking.


Fish is finished cooking when it reaches an internal temperature of 145 ° F.

This applies to all types of fish, whether you are grilling, baking, or pan-frying it.

However, keep in mind that some types of fish cook faster than others. For example, thinner fillets of fish will usually cook through more quickly than thicker ones. 

If you’re unsure whether your fish is fully cooked, use a meat thermometer to verify its internal body temperature. Err on the side of undercooking when in doubt about your fish rather than overcooking it!
