Biblical Definition of Clean and Unclean Fish
The question of whether a fish is "clean" or "unclean" originates from biblical dietary laws, particularly those found in Leviticus 11 and Deuteronomy 14. For aquatic creatures, the rule is straightforward and explicitly stated: only those with both fins and scales are considered clean and therefore permissible for consumption. Any aquatic creature lacking either of these features, such as shellfish, eels, or catfish, is deemed unclean. This distinction is not based on health, but rather on a set of divine commands that followers are instructed to observe as part of a holy life. The law provides a clear and unwavering framework for what is and is not acceptable seafood.
Why Mackerel is Considered a Clean Fish
Mackerel belongs to a family of fish that includes many species, and the kosher status of mackerel largely depends on the specific type. Most common mackerel species, like the Atlantic mackerel (Scomber scombrus), the Spanish mackerel (Scomberomorus maculatus), and the Chub mackerel (Scomber japonicus), are indeed equipped with both fins and scales. While the scales on some mackerel are very small and may be difficult to see or easily shed when caught, their presence is sufficient to meet the biblical criteria. For those seeking confirmation, authoritative kosher lists, such as those maintained by Jewish organizations, explicitly include mackerel as a kosher fish. This is in stark contrast to creatures like shellfish (shrimp, lobster, crab), which lack scales and are unequivocally unclean.
Other Mackerel Species and Exceptions
It is important to note that the term "mackerel" can be used broadly, and some less common types may not conform to the kosher requirements. For example, some "mackerel" are actually members of different families. The Atka mackerel (Pleurogrammus monopterygius) is sometimes mentioned as potentially lacking obvious scales, but it's not a true mackerel from the Scombridae family. Therefore, for strict observance, it's prudent to confirm the specific species or rely on certified kosher sources. However, the most widely consumed varieties of mackerel are confirmed as clean according to biblical and kashrut standards.
Comparing Mackerel with Other Fish Based on Cleanliness
| Feature | Mackerel (Atlantic & Spanish) | Salmon | Catfish | Shellfish (Shrimp, Crab) |
|---|---|---|---|---|
| Fins | Yes | Yes | Yes | No |
| Scales | Yes (small, but present) | Yes | No | No |
| Biblical Status | Clean | Clean | Unclean | Unclean |
| Reason for Status | Has both fins and scales | Has both fins and scales | Lacks scales | Lacks fins and scales |
Considerations Beyond Religious Laws
Beyond religious interpretations, the modern understanding of "clean" and "unclean" can relate to health and environmental factors. Mackerel is a highly nutritious, oily fish, rich in heart-healthy omega-3 fatty acids, protein, and vitamins such as D and B12. It supports brain function, boosts immunity, and promotes healthy skin and hair. However, some species, particularly King mackerel, contain higher levels of mercury, a potential health risk, especially for pregnant women. Atlantic and Pacific mackerel are generally recommended as they are lower in mercury. Furthermore, sourcing needs consideration, as overfishing of North-east Atlantic mackerel has led to sustainability concerns. Choosing sustainably caught or hand-lined mackerel is a more environmentally conscious choice. Thus, while biblically clean, modern consumers also weigh factors like mercury and sustainability.
Conclusion
For those adhering to dietary laws from religious texts like Leviticus, mackerel is considered a clean fish because it possesses both fins and scales. The presence of these key features confirms its kosher status, making it permissible for consumption. While the scales on some species may be small, they meet the specified criteria. Outside of religious contexts, mackerel is valued for its nutritional benefits, including its high content of omega-3s, protein, and various vitamins and minerals. However, modern ethical and health considerations, such as mercury levels in certain species and sustainability, are also important factors for the contemporary consumer. A balanced view, taking into account both ancient and modern perspectives, offers a comprehensive answer to the question of whether mackerel is a "clean" fish.
Frequently Asked Questions
What makes a fish 'clean' according to the Bible?

Some species, like King mackerel, have higher mercury levels. To minimize risk, it's recommended to eat lower-mercury varieties like Atlantic mackerel in moderation.
Is mackerel fishing sustainable?
Sustainability is a growing concern for mackerel, particularly North-east Atlantic stocks due to overfishing. Consumers should look for sustainable options, such as hand-lined mackerel or those with MSC certification.
