Canning fish is a fantastic way to preserve your catch, create a convenient and healthy pantry staple, and enjoy delicious seafood year-round. However, not all fish are created equal when it comes to canning. Selecting the right type of fish is crucial for both safety and taste. This comprehensive guide will walk you through the best fish for canning, providing insights into their characteristics, preparation, and potential flavor profiles.
Understanding the Fundamentals of Canning Fish
Before diving into specific species, it’s important to grasp the basics of canning fish. Canning involves sealing fish in airtight jars and heating them to a temperature high enough to kill harmful bacteria, particularly Clostridium botulinum, which causes botulism. Proper processing times and methods are essential for food safety. Always follow tested and approved canning recipes from reliable sources like the USDA Complete Guide to Home Canning or your local extension office.
Fish can be canned in various mediums, including water, oil, or brine. The choice depends on the type of fish and your desired flavor. Oily fish, like salmon and mackerel, often benefit from being canned in their own oil, while leaner fish may require added moisture.
Top Choices for Canning: Oily Fish
Oily fish are generally considered excellent candidates for canning due to their natural oil content, which helps preserve their flavor and texture. They also tend to have a richer taste that stands up well to the canning process.
Salmon: The King of Canned Fish
Salmon is arguably the most popular and widely canned fish. Its rich flavor, high omega-3 fatty acid content, and firm texture make it a top choice for both home canners and commercial producers.
Types of Salmon for Canning: Several varieties of salmon are suitable for canning, each with its unique characteristics:
- Sockeye Salmon: Known for its deep red color and intense flavor, sockeye salmon is a premium choice for canning. Its high oil content contributes to a moist and flavorful finished product.
- Coho Salmon: Coho salmon, also called silver salmon, has a milder flavor than sockeye but still offers a rich taste and good texture. It’s a good option for those who prefer a less intense salmon flavor.
- Pink Salmon: Pink salmon is the most abundant and often the most affordable type of salmon. It has a lighter color and a more delicate flavor. While it can be canned successfully, it may require more careful handling to prevent it from becoming too dry.
- King (Chinook) Salmon: The largest and arguably the richest salmon, King salmon produces an incredibly luxurious canned product. Due to its high fat content, it’s often canned in its own oil, resulting in a decadent flavor.
Preparing Salmon for Canning: The preparation process typically involves scaling, gutting, and cleaning the salmon. You can choose to leave the skin on or remove it, depending on your preference. Some canners also remove the bones, while others prefer to leave them in, as they soften during the canning process and become a good source of calcium.
Mackerel: A Nutrient-Packed Option
Mackerel is another excellent choice for canning. It’s an oily fish with a strong, distinct flavor and a high concentration of omega-3 fatty acids. Its firm texture holds up well to the canning process.
Types of Mackerel for Canning: Several types of mackerel are commonly canned:
- Atlantic Mackerel: This is the most common type of mackerel found in North Atlantic waters. It has a rich, oily flavor and a firm texture.
- Pacific Mackerel: Similar to Atlantic mackerel, Pacific mackerel is found in the Pacific Ocean and has a comparable flavor and texture.
- Spanish Mackerel: Spanish mackerel has a slightly milder flavor than Atlantic or Pacific mackerel, but it’s still a good option for canning.
Preparing Mackerel for Canning: Mackerel should be gutted, cleaned, and the head removed. Some canners also remove the skin, although it’s not necessary. Mackerel can be canned whole, filleted, or cut into chunks.
Tuna: A Versatile and Popular Choice
Tuna is a hugely popular choice for canning, primarily due to its mild flavor and versatility. It’s a good source of protein and omega-3 fatty acids.
Types of Tuna for Canning: The most common types of tuna used for canning are:
- Albacore Tuna: Albacore tuna is known for its light color and mild flavor. It’s often labeled as “white tuna” and is considered a premium choice for canning.
- Skipjack Tuna: Skipjack tuna has a stronger flavor than albacore and is often labeled as “light tuna.” It’s a more affordable option and is commonly used in tuna salad and other recipes.
- Yellowfin Tuna: Yellowfin tuna has a milder flavor than skipjack but a stronger flavor than albacore. It’s a good option for those who want a balance between flavor and affordability.
Preparing Tuna for Canning: Tuna requires careful handling due to its size and potential for histamine formation. It’s important to keep the fish cold throughout the preparation process. Tuna is typically steaked or chunked before canning.
Sardines: Small but Mighty
Sardines are small, oily fish that are often canned whole. They are packed with nutrients, including omega-3 fatty acids, calcium, and vitamin D.
Types of Sardines for Canning: The term “sardine” refers to several different species of small, oily fish, including:
- European Sardine (Pilchardus pilchardus): This is the most common type of sardine found in European waters.
- Sprat (Sprattus sprattus): Sprat is a small, oily fish that is similar to sardines and is often canned as “brisling sardines.”
Preparing Sardines for Canning: Sardines are typically canned whole, with the head removed. They can be canned in oil, water, or various sauces.
Leaner Fish Options for Canning
While oily fish are generally preferred for canning, leaner fish can also be canned successfully with proper preparation and techniques. The key is to add moisture and fat to prevent the fish from drying out during the canning process.
Trout: A Delicate Flavor
Trout is a freshwater fish with a delicate flavor and a flaky texture. It can be canned successfully, but it’s important to add oil or other fat to prevent it from becoming too dry.
Preparing Trout for Canning: Trout should be gutted, cleaned, and the head removed. It can be canned whole, filleted, or cut into chunks. Adding a small amount of olive oil or other cooking oil to the jar can help preserve its moisture and flavor.
Catfish: A Southern Staple
Catfish is a popular fish in the Southern United States and can be canned for a convenient and shelf-stable source of protein.
Preparing Catfish for Canning: Catfish should be skinned and filleted before canning. It’s important to remove the dark meat, as it can have a strong flavor. Adding a brine or a small amount of oil to the jar can help improve the flavor and texture.
Other Lean Fish: Exploring the Possibilities
Other leaner fish, such as cod, pollock, and haddock, can also be canned, but they require careful preparation and the addition of moisture and fat. Experimenting with different brines and seasonings can help enhance their flavor and prevent them from becoming too dry.
Essential Canning Tips for Fish
Regardless of the type of fish you choose to can, following these essential tips will help ensure a safe and delicious finished product.

While the natural flavor of fish is often delicious on its own, you can enhance the flavor of your canned fish with various seasonings and ingredients.
- Salt: Salt is an essential ingredient for canning fish. It helps preserve the fish and enhances its flavor.
- Spices: Adding spices like black pepper, garlic powder, onion powder, or smoked paprika can add depth and complexity to the flavor of canned fish.
- Herbs: Fresh or dried herbs, such as dill, thyme, or bay leaf, can also be used to flavor canned fish.
- Lemon juice or vinegar: Adding a small amount of lemon juice or vinegar can help brighten the flavor of canned fish.
- Chili peppers: For those who like a little heat, adding a small chili pepper or a pinch of red pepper flakes can add a spicy kick to canned fish.
Safety First: Preventing Botulism
Botulism is a serious and potentially fatal illness caused by the bacterium Clostridium botulinum. It is crucial to follow proper canning procedures to prevent botulism. Fish must be processed in a pressure canner to reach the temperatures needed to kill botulism spores. Always follow tested recipes and guidelines from reputable sources like the USDA or your local extension office. Inspect your jars for any signs of spoilage before opening and discard any that show signs of bulging, leakage, or unusual odor.
Enjoying Your Home-Canned Fish
Once you’ve successfully canned your fish, the possibilities are endless. Canned fish can be enjoyed straight from the jar, added to salads, used in dips and spreads, or incorporated into various recipes.
Canned salmon, for example, is excellent in salmon patties, salmon salad, or as a topping for crackers. Canned tuna is a classic ingredient for tuna salad sandwiches, tuna casserole, or tuna melts. Canned sardines can be enjoyed on toast, added to pasta dishes, or used as a topping for pizza.
Canning fish is a rewarding and sustainable way to enjoy delicious seafood year-round. By choosing the right type of fish, following proper canning procedures, and experimenting with different flavors, you can create a pantry full of healthy and convenient meals. Remember to prioritize safety and always follow tested recipes to ensure a safe and enjoyable canning experience.
What types of fish are best suited for canning, and why?
Oily fish, such as salmon, tuna, mackerel, and sardines, are generally the best choices for canning. Their higher fat content helps to preserve moisture during the canning process, resulting in a more flavorful and less dry final product. The oil also contributes to a richer texture, making the canned fish more palatable and enjoyable to eat.
While leaner fish like cod or tilapia can be canned, they tend to become drier and less flavorful. If you choose to can leaner fish, consider adding a small amount of oil (olive or vegetable) to the jars before processing to help retain moisture and enhance the taste. Proper processing times and careful handling are crucial regardless of the type of fish you choose.
What are the key considerations for fish freshness when canning?
Freshness is paramount when canning fish. Use only the freshest fish possible, preferably caught or purchased within 24 hours of canning. Look for clear eyes, bright red gills, and firm, elastic flesh that springs back when touched. Avoid fish that smells overly fishy or ammonia-like, as this indicates spoilage.
Properly chilling the fish from the moment it’s caught or purchased is essential. Keep the fish on ice or refrigerated at temperatures below 40°F (4°C) to slow down bacterial growth and enzymatic activity. This will not only improve the safety of the canned product but also ensure a higher quality flavor and texture.
What are the essential steps in preparing fish for canning?
Proper preparation is crucial for safe and delicious canned fish. Begin by thoroughly cleaning the fish. Gut and scale it, then remove the head and tail. Rinse the fish under cold, running water, ensuring all traces of blood and internal organs are removed. You can either leave the bones in (they will soften during processing and provide calcium) or remove them if desired.
Next, cut the fish into pieces that will fit comfortably in your canning jars, leaving about one inch of headspace. Pack the fish tightly into the jars, leaving the appropriate headspace as directed by your canning recipe. Adding a small amount of salt is common for flavor, and some recipes may include other seasonings. Be sure to follow tested and approved canning recipes to ensure safety.
Is it necessary to pressure can fish, and why?
Yes, it is absolutely necessary to pressure can fish. Fish is a low-acid food, meaning it has a pH level above 4.6. This makes it susceptible to the growth of Clostridium botulinum, the bacteria that produces botulism toxin. Botulism is a serious and potentially fatal illness.
Pressure canning is the only safe method for canning low-acid foods like fish because it reaches temperatures high enough (240°F or 116°C) to destroy Clostridium botulinum spores. Water bath canning does not reach these temperatures and therefore cannot guarantee the destruction of the bacteria in fish, making it unsafe.
What are the common signs of spoilage in canned fish?
There are several signs that indicate canned fish may be spoiled and unsafe to consume. The most obvious sign is a bulging lid or a leaking jar. This indicates that gases are being produced inside the jar, often due to bacterial growth. Other signs include a foul or unusual odor upon opening the jar.
Visually, look for discoloration, mold growth, or a cloudy or milky appearance to the liquid inside the jar. If the fish has an off taste or texture, such as being slimy or mushy, it is also a sign of spoilage. If you notice any of these signs, discard the entire jar without tasting it. Remember the saying, “When in doubt, throw it out.”
How does the type of canning jar impact the safety and quality of canned fish?
Using the correct type of canning jar is critical for safety and achieving a proper seal. Only use glass canning jars specifically designed for home canning, such as those made by Ball or Kerr. These jars are tempered to withstand the high temperatures and pressures involved in the canning process and are designed to create an airtight seal.
Avoid using recycled jars from commercial products, such as mayonnaise or pickle jars. These jars are not designed to withstand the heat and pressure of canning and may crack or break, resulting in a failed seal and potential spoilage. Use only new, two-piece canning lids (flat lid and screw band) each time you can, as the sealing compound on used lids may be compromised.
What are the best practices for storing canned fish after processing?
Proper storage is essential for maintaining the quality and safety of your canned fish. After processing and confirming that the jars have sealed correctly, remove the screw bands and wipe down the jars with a clean, damp cloth. Store the jars in a cool, dark, and dry place. Ideal storage temperatures are below 70°F (21°C).
Avoid storing jars in areas that are subject to temperature fluctuations or direct sunlight, as these can affect the quality of the product and potentially compromise the seal. Properly canned fish can be stored for at least one year, and in some cases longer, but it’s best to use it within that timeframe for optimal flavor and texture. Always check for signs of spoilage before consumption, even if the fish has been stored correctly.
