Crustacean & Marine Meals

Crustacean & Marine Meals, crab, or shrimp meal, is a form of organic fertilizer. It is made from crustaceans like crabs or lobsters. The shells of these creatures are rich in nutrients, which when added to the soil helps create an ideal growing environment for flowers and vegetables.

Fertilizer made of shellfish is composed of the shells of crustaceans such as crabs, shrimp, or even lobsters and is also called shrimp or crab meal. The shells, which are rich in nitrogen, are mixed with coarse carbon rich material such as wood shavings or chips, leaves, branches, and bark.

This is allowed to compost over the course of several months while microorganisms feast on the proteins and sugars, effectively converting the pile into rich humus. As the microorganisms feed on the shellfish proteins, they generate plenty of heat, which reduces pathogens, thus eliminating any nasty, fishy odor and at the same time killing any weed seeds.
