Why is pollock replacing cod in fish and chips?

Pollock isn't *replacing* cod in fish and chips, but it has become a common alternative in recent years. This is due to a combination of factors:

* Overfishing of cod: Cod stocks have declined significantly due to overfishing, making it more expensive and less sustainable to use in fish and chips.

* Pollock availability: Pollock stocks are more plentiful and sustainable, making it a more attractive option for fish and chip shops.

* Taste and texture: While not identical to cod, pollock has a milder flavour and similar flaky texture, making it a suitable substitute in many dishes.

* Cost-effectiveness: Pollock is generally cheaper than cod, making it a more affordable option for businesses.

However, it's important to note that not all fish and chip shops use pollock. Many still use cod, especially those that prioritize using sustainable seafood. Some shops may also use other types of white fish, like haddock or hake.

Ultimately, the choice of fish is up to the individual shop and their customers. While pollock is a popular alternative, cod remains the traditional and preferred choice for many fish and chip lovers.
