This comprehensive guide explores which parts are safe and delicious to eat, offering a deeper appreciation for the entire catch.

Did you know that crustacean shells, including crab shells, contain significant amounts of calcium carbonate, often comprising 30–50% of their dry weight? Yes, a crab shell is high in calcium and minerals, presenting a significant and sustainable source of this essential nutrient.

According to a 2025 study from The Fish Site, fish heads are a potential resource with significant lipid content, contradicting the misconception that they contain no fat. This article explores the types of fats found in fish heads and their nutritional value.

Shrimp shells account for nearly half of the shrimp's total weight and are often discarded, yet they contain valuable compounds that are sometimes overlooked. For many, the tough, fibrous texture of a shrimp shell makes it seem unappealing and inedible, but a deeper look reveals potential nutritional value and significant culinary uses.
