Alaska pollock is a popular, mild-flavored whitefish found in abundance in the icy waters of the North Pacific. It's a staple in many cuisines, often showing up in fish sticks, surimi (imitation crab meat), and other processed foods. But one question often arises: does Alaska pollock have scales? The short answer is yes, but understanding the specifics reveals a more nuanced story.

The Tiny Scales of Alaska Pollock

Yes, Alaska pollock does have scales. However, these scales are incredibly small and thin, almost cycloid in nature. Unlike the larger, easily visible scales of fish like salmon or trout, pollock's scales are quite delicate. This is why they're often removed during processing or are so small you don't notice them.

Why You Might Not Notice the Scales

Several factors contribute to the often-unnoticed presence of pollock scales:

Size: As mentioned, the scales are minuscule.
Processing: Commercial processing of pollock for food products often involves steps that remove the scales. This makes the final product appear scaleless. Think of the process of making fish sticks; the fish undergoes significant processing before it's breaded and frozen.
Texture: The scales are thin and easily detached, blending into the flesh.

The Biology Behind the Scales

Pollock scales, like those of other bony fish, play a vital role in protecting the fish's skin and regulating its body temperature in the cold, deep waters where it thrives. They're embedded in the dermis (the deeper layer of skin).

Types of Fish Scales

Different types of fish have different types of scales. Pollock's are relatively small and smooth compared to some other fish species, helping them move efficiently through the water.

Cycloid scales: These are thin, overlapping scales with smooth edges, typical of many soft-rayed fish. Alaska pollock scales are considered to be of this type, though very small.
Ctenoid scales: These have tiny comb-like projections on their edges.
Ganoid scales: These are thick, bony scales, found in some fish like gars.
Placoid scales: These are tooth-like scales found in sharks and rays.

Frequently Asked Questions About Alaska Pollock Scales

Q: Are Alaska pollock scales safe to eat?

A: Yes, Alaska pollock scales are safe to eat if accidentally ingested. They are digestible and pose no known health risks. However, they're typically removed during processing, so it's rare to encounter them in most food products.

Q: Why are pollock scales so small?

A: The size and texture of pollock scales are likely adaptations to their environment. Their small size may help reduce drag while swimming in the water column.

Q: Can I see the scales on a fresh, unprocessed Alaska pollock?

A: While the scales are small, you might be able to see them on a very fresh, unprocessed Alaska pollock with close examination, particularly under good light. However, they are still quite difficult to see.

Conclusion: The Truth About Pollock Scales

While Alaska pollock possesses scales, their minuscule size and the processing methods used to prepare pollock for consumption often lead people to believe they are scaleless. Understanding the nature of these tiny scales offers a clearer picture of this widely consumed fish and its biology. So, the next time you enjoy some fish sticks, remember that those delicious morsels did indeed once have very small scales!
