StackPac road transport systems are a versatile solution for land and sea based live seafood transportation requirements

FishPac’s Live Seafood Transport System is the flexible solution for all your freight needs.

Traditionally used for oxygen supported air transport, FishPac’s StackPac unique, flexible design sets it apart from competitor products.  With the versatility to meet road transport and sea specifications, FishPac’s road and boat / barge transport potential lies in its ability to operate in a variety of modes without any structural modifications.

Versatility comes as standard

If your shipping system is limiting transport options and impacting on product quality, it’s time to make a change.

The historic need to use different containers for different transport methods, and at different stages of the product journey, has significant implications in terms of capital investment and product viability.

Now, thanks to FishPac’s innovative StackPac design, a single modular product has all the capabilities you need to transport, store and care for seafood in optimal conditions. No need for different containers for different purposes or transport methods.

Without any structural modification, the StackPac transport bin can be used:

  • For live seafood transport across land, sea and air
  • As a modular stock holding tank/purging tank – meaning no unnecessary movement of stock, which in turn reduces stress and mortality
  • As a Bio-filter bin – removing waste and improving water quality and, hence, product health and viability

Live Seafood Transport System

The standard air freight FishPac StackPac bin is suitable for all transport modes. It comprises:

  • FishPac StackPac Live Seafood Transport bin
  • FishPac Oxygen regulator
  • Oxygen cylinder (supplied by client)

By simply changing the dual stage air freight regulator for a single stage road freight regulator, the opportunities for usage are vastly expanded.  Operationally both systems are identical, with the regulator used in air transport requiring additional safety features to that used on land or sea.

As the system is modular and fully self-contained, it can be used with all forms of road transport.   There is no need for expensive and capital restrictive tanker trucks.

The FishPac point of difference

The bin’s double plug water outlet is key to its versatility. While only a single outlet plug is required for land transport, the addition of this feature means it is compliant with air transport regulations, minimising the risk of water leakage:

  • 316 stainless steel threaded fitting
  • Internal thread 50mm (2″)
  • External thread 75mm (3″)
  • Seal plugs are both installed from outside the bin.

So how does it work?

By utilising the 50mm thread, an internal standpipe, to maintain water depth with the seal plug removed can be installed. The process is simple.

  1. From inside the bin, screw a 50mm PVC pipe connection (male thread/female socket) tightly into the outlet fitting
  2. Into the female socket install a short length of 50mm PVC pipe and 90⁰ PVC elbow
  3. Determine required water height and cut a length of 50mm PVC pipe to suit
  4. Insert pipe into vertical outlet of 90⁰ elbow
  5. It is also advantageous to draw water from the base of the bin, which aids removal of faeces. A larger diameter pie should be cut to a length longer than the standpipe and slots cut in the lower portion of the pipe. This should be placed over the standpipe (slots to base of the bin). Under flow through operation discharge water is taken from the base of the bin and passes upwards through the collar pipe to discharge out the 50mm pipe attached to the bin outlet. (see diagram).

Flow-through capability eliminates land transport limitations

By minimising handling of live seafood you avoid both physical damage and stress.

During transport the FishPac bin operates exactly the same as during air transport. However, over time the water quality deteriorates and, hence, road transport payloads can be affected. This limiting factor can be entirely eliminated simply by using the internal standpipe.

By flushing the bins with new water at regular intervals during transport, you can:

  • Protect water quality during the transport event
  • Deliver a higher quality product
  • Potentially extend total transport time

Flushing of the system is simple, as the standpipe maintains water within the bin after the discharge plug has been removed. Water will not flow out of the bin unless water is added to the system, causing the system to overflow.

To facilitate this process, FishPac recommends the bin lid be modified with an entry point drilled through the lid and the insertion of a valve. When water is to be added to the system a hose can be attached to the valve.

In the event that you subsequently wish to use the system for air transport – FishPac can supply new lids.

For discharge of waste water, a 75mm flat hose attached to a 75mm male thread fitting is suggested. The hose can be unrolled to allow the waste water into the discharge point.

Modular Stock Holding Tank/Purging Tank

When configured with the internal standpipe, the FishPac bin can be used as a modular holding tank. It is equally suited to single flow through and recirculation stock holding and aquaculture systems.

A flexible hose with a 75mm male thread can be fitted to the bin outlet and the facility water discharge point. Water input is from the facility supply piped to the holding tank.

Oxygen or air supply for the system can be sourced from the facility supply, via a hose with the same male compression fitting as used on the oxygen regulator hose connected to the bin bulkhead female fitting.

When used for purging of product, removal of waste will be facilitated by the collar pipe drawing waste water from the bottom of the bin. In addition it will be practical to siphon physical waste from the bottom of the bin.

Using the bin as a Modular Holding Tank/Purging Tank minimises handling

By using a singular bin for holding and transport, you can minimise handling of the product and, therefore, risk of damage and stress. Without moving or handling the fish, the system temperature can even be manipulated to further calm them prior to transport.

Preparation of the bin for transport is simple. Follow these guidelines, in conjunction with standard FishPac Operating Procedures:

  • Install the oxygen cylinder and oxygen regulator system in the bin compartment
  • Turn on, remove facility oxygen system and connect cylinder system.
  • Turn off water supply
  • Install and seal bin lid
  • Disconnect water discharge hose
  • Install outer bin plug
  • Remove bin from facility and load on transport vehicle.

Biofilter Bin

 The FishPac bin can be readily used as components of a recirculation system for a holding tank facility or aquaculture operation.

Configured with the internal standpipe and collar it can serve as a containment vessel for biofilter media. It is recommended a false floor be installed to a height above the base of the collar pipe of the standpipe. This false floor can simply be a FishPac support tray covered with fine oyster mesh.

The biofilter media can fill the bin and the water spay input should be uniform over the surface of the media. The internal water level will be maintained by the standpipe and water flow will be down through the media and return to the system via the standpipe.

The system can be plumbed to the facility using the 75mm water outlet of the bin. If the internal bas screen is 50mm from the floor of the bin, useable biofilter volume is approximately 800litres.

The systems can be multiplied in series to increase biofilter capacity.
