The devices once utilized in retail environments to house live crustaceans are the central focus. These systems, typically constructed from plastic and metal, were implemented to maintain a controlled aquatic environment for the temporary storage of seafood, specifically lobsters, before purchase. They are characterized by their filtration, temperature regulation, and aeration components, all designed to maximize the lifespan of the marine animals within a commercial setting.
The adoption of these storage units provided a tangible benefit to grocery chains by presenting consumers with the perception of freshness and quality. The units allowed for a more extended holding period compared to traditional methods of storing seafood on ice. Their historical context lies within the broader narrative of the evolution of food distribution and the increasing demand for readily available, live seafood products in landlocked areas.
