Crustaceans are used in agriculture primarily for what purpose?

Crustaceans are commonly used in agriculture primarily as bait. This application is especially relevant in the context of fishing, where crustaceans such as shrimp and crabs serve as effective attractants for various fish species. Their natural scent and movement appeal to fish, making them a preferred option for anglers seeking to enhance their catch rates.

While crustaceans could theoretically serve other agricultural roles, such as being used in some organic fertilizers through their decomposed forms or as a food source for livestock, these uses are far less common compared to their role as bait in fishing. Pollination is primarily a role filled by insects, such as bees, rather than crustaceans, which do not perform this function in agricultural ecosystems.
