In order to help grow your mussel crop our floats offer several distinct advantages. The oval shape design reduces the impact on the float from the ocean during rough seas, which in turn reduces the loss of crop from your lines.

The design ensures that JFC Marine floats have a low profile in the water, causing limited vertical motion and consequently reduces stress on the mussels. All of these factors culminate in significantly increased yields over a shorter time period for the mussel farmer. 

Our float handles are offset from the centre of the float. The purpose of this is so that your head line will be submerged using only 25% of the float’s floatation compared to others amounting to 50% floats of the float’s floatation.

A unique patented fin design also reduces the movement of the float in the water making the line more stable even in rough sea conditions.  This in turn, reduces the loss of mussel crop on long lines.

For ease of handling, the mooring eyes are strong and durable with both a long and wide opening. This increases the lashing area for the head line and reduces the risk of wear and tear on your head line rope.

Our floats are manufactured in a marine grey colour which reduces the visual impact to surrounding environment. The polyethylene used is fortified with UV stabilisers designed especially for marine applications.  

Our Beach Marker Buoys offer a high visibility lightweight solution ideal for marking navigation channels, small ports and inner harbours, inland water ways and beach areas for the safe marking of swim zones and jet ski channels. Our Beach Marker Buoys are fully recyclable and are manufactured from marine grade virgin polyethylene. Available foam filled if required. 

Small and lightweight Cone and Can shape navigation buoys provide a highly visible solution with a Nominal Focal Height of 900mm. Manufactured from strong durable polyethylene. Fully foam filled with internal ballast for stability. Fitted with 2 lifting eyes for ease of manoeuvrability during installation and servicing. Designed for use with self-contained lanterns with the option of a top mark if required. Ideal for marking temporary construction areas, racing marks, safe water channels, outfalls and aquaculture sites.

Selecting shrimp at the appropriate age and size at initial capture is vital in order to allow the smaller species to be returned to its natural environment than having to reject a relatively high proportion of the catch.

Our shrimp grader trays are available in 3 sizes: 8mm, 9mm, and 10mm sizes (including collection box).  Also available is a 20mm pre-grader tray used to remove crabs or fish from the shrimp catch.

Depuration (purification) is a process by which shellfish are held in tanks of clean seawater under conditions which maximise the natural filtering activity and results in the expulsion of intestinal contents. The depuration process involves placing shellfish into a purpose made tank which is then filled with clean seawater. The seawater is mainly treated by ultraviolet (UV) disinfection, and is then recycled through the system providing optimum temperature, salinity and oxygen levels for the shellfish to function normally and expel faecal contamination.

Quantity of oysters per tank to be depurated:
 – Pacific oysters (Crassostrea gigas) approximately 100 – 110 kg.*, 
 – Flat oysters (Ostrea edulis) approximately 110-120 kg.*

*Always leave a layer of seawater of at least 5cm high above the oysters.
