Shellfish Capacity in a Lobster Tank

When it comes to storing live shellfish, particularly lobster and crab, capacity isn’t just a matter of volume—it’s about ensuring optimal conditions for animal health, water quality, and operational efficiency. At the core of our system design philosophy is a deep understanding of stocking density, tank surface area, and the critical importance of gas exchange.

Traditionally, shellfish storage tanks operate within recommended limits of 25 to 40 kg per square metre for lobster and up to 100 kg per square metre for crab. These guidelines are designed to prevent overcrowding, which can lead to physical damage to the shellfish and hinder water flow, both of which compromise the overall health of the stock.

Lobster Pod Shellfish Capacity

The Lobster Pod offers a revolutionary alternative. Each tray within the Lobster Pod is engineered to hold up to 10 kg of lobster or crab without stacking. This eliminates the risk of damage from overcrowding and ensures a more even distribution of water around the stock. It also means that the likelihood of overstocking is significantly reduced—one of the key advantages of our system.

Beyond stocking density, surface area plays a vital role in maintaining water quality. Conventional tanks such as IBCs or pallet tanks typically provide around one square metre of floor space, allowing for approximately 40 kg of lobster under ideal conditions. In contrast, the Lobster Pod multiplies this capacity significantly. By stacking trays vertically within the same footprint, you can effectively triple your storage capacity without compromising the well-being of your shellfish.

Surface Area for Gas Exchange

Another often-overlooked factor is gas exchange. The Lobster Pod dramatically increases the floor area within the same footprint—by up to eight times compared to standard tanks. This expanded surface area enhances oxygen absorption and facilitates the release of carbon dioxide, two essential elements for maintaining optimal water chemistry. Enhanced gas exchange means better water quality, healthier shellfish, and more efficient use of your available space.

Conclusion

In essence, the Lobster Pod is designed to overcome the limitations of traditional shellfish tanks. It combines smart engineering with a deep understanding of aquatic biology to deliver higher capacity, better water flow, and improved gas exchange—all within the same compact footprint. If you’re looking to maximise your shellfish storage while maintaining the highest standards of stock health, the Lobster Pod is the intelligent choice.
