0-500-OT: old type, for use with Bayco wire on a 10.5mm (7/16") longline.
0-500-9: new type, for use with end caps on a 9mm (3/8") longline.
0-500-10.5: new type, for use with end caps on a 10.5mm (7/16")longline.

Dimensions:
11.2cm (4 2/5").

Weight:
10.2g, 0.36 oz.

Use:
10.2g, 0.36 oz.

Clip to bag. If used with end caps, 0-510, snap into spot provided on top of cap. If used with Bayco wire, 0-502, 0-503, thread Bayco wire through bag, threading bag clips onto Bayco wire near each end of bag.

Features / benefits:
Clamp easily and securely to longline and bags, quick deployment and harvesting. Free-moving, allowing bags to move with wave action, controls bio-fouling, aids in natural shell-pruning for better cupping and higher meat yield, shell-hardening for specialized markets.

Manufactured in Australia.

Features / benefits:
Longline snaps in and out of hook, puts the "adjustable" in the ALS. Allows for change in bag height relative to water, bags can be at desired depth to control shell growth, conditioning and cleaning, as well as limiting bio-fouling.

Manufactured in Australia.


Bayco Wire
O-502, O-503


Description:
Black cord made of a monofilm product (0-502) or polyethylene (0-503).

Dimensions:
0-502-4 and 0-503-4: 4mm (3/16") diameter.
0-502-5: 5mm (7/32" diameter).

Use:
To close oyster grow-out bags and attach clips to bags in the ALS. Can also be used, covered with dripper tube, as longline in high-energy areas.

How it is used / deployed:
To hold bag clips on, cord is strung through top of bag and through clips. to close bags, the same piece of cord is bent near the end and heated to hold the bend. The bag is folded closed, cord is stretched over end and hooked through bag mesh.

Features / benefits:
Light, strong, durable, non-conductive, long-lasting, Excellent handling characteristics, will conform and be handled like steel or galvanized wire, but is smooth and won't snag.

Manufactured in Australia/USA.


Dripper Tube
O-507-LD
O-507-HD

Description:
Tube material made of black plastic.

Dimensions:
Diameters 9mmLD, (3/8") and 10.5mmHD, (7/16").

Use:
Used with Bayco wire as an alterative to aquacable for the longline of the ALS system to suspend oyster bags.

How it is used / deployed:
Bayco wire is threaded through the tube creating a lonline. The longline is attached at both ends to strainer posts. The cable is suspended throughout the system by fence risers attached to line posts. Risers are used so the longline can be raised and lowered at intervals of 10.16cm, (4") or more, allowing the oyster cages to be submerged or at the surface, depending on the season and site specifics.

Features / benefits:
For use in high energy areas where aquacable is not suitable, because of the wearing of the aquacable by the bag clips due to increased weave action and rough water conditions.

Manufactured in Australia.


Fukui Aquacable

Use:
Used as the longline of the ALS system to suspend oyster bags.

How it is used / deployed:
The longline is attached at both ends to strainer posts. Wire grips are used to tighten the cable. The cable is suspended throughout the system by fence risers attached to line posts. Risers are used so the longline can be raised and lowered at intervals of 10.16cm, (4") or more, allowing the oyster cages to be submerged or at the surface, depending on the season and site specifics.

Features / benefits:
Coated in high density polyethylene to protect the inner core of the rope has very low elongation due to spectra fiber and construction.
