Here's why:
* Conservation concerns: Many shark species are facing threats from overfishing, habitat loss, and bycatch. This has led to regulations and conservation efforts to protect them, making people hesitant to eat shark meat.
* Mercury levels: Some shark species accumulate high levels of mercury, a neurotoxin that can be harmful to human health, particularly for pregnant women and young children.
* Taste and texture: Shark meat can be tough and have a strong fishy flavor, which some people find unappealing.
While you might find shark meat on some restaurant menus or at specialty markets, it is not a staple food in California and is generally considered a niche product.
