Floating Islands

Floating Islands

Floating Islands are a modular unit system that allows the creation of custom made Floating Islands. They can incorporate unique solutions such as anti-predator fish refuges (artificial reefs), biological filters, anti-grazing frames and spawning medium.

They offer a unique range of benefits to lakes, reservoirs and ponds. Anchored off-shore, they reduce bank erosion by dissipation of the wave energy whilst the emergent plants form an effective buffer to wave and wind action. On lakes where water sports take place the islands can give protection to vulnerable stands of emergent and marginal plant life, whilst providing area markers and even forming barriers to separate activities.

Floating Islands can bring about a dramatic improvement in the ├Žsthetic appearance on most waters. They can be installed purely to improve and enhance the landscape value.

They also provide valuable habitat for conservation and to encourage biodiversity. The creation of habitat sanctuaries, both below and above the waterline, will enhance the biodiversity of a host species which might include birds, dragonflies, invertebrates, amphibians and fish.

The root structure of a Floating Island offers a unique opportunity to underwater dwelling organisms. When the root structure of the pre-established coir pallet is combined with a protection cage, it forms an effective fish refuge from cormorant and other predation. The extended root structure also makes an ideal spawning medium for fish at the appropriate time of year. This will have a positive effect in encouraging a naturally and self-sustaining aquatic community and balanced ecology. The root system of Floating Islands is the home for beneficial bacteria which naturally improve biological processes such as the nitrogen cycle. The root system, in addition to providing excellent spawning medium for fish, forms a matrix for absorbing dissolved pollutants and filtering and retaining suspended solids.

The addition of an anti-predator refuge (artificial reef) below a Floating Island will make predation by cormorants, mink, otters and other avian predators more difficult. Artificial reefs are available as a 'bolt-on' extra and are supplied as a customised solution to individual predation problems. These fish refuges, which provide excellent protection from predation in winter, also provide fry habitat in the summer.

A Floating Island through spring, summer and autumn provides a larder of food for juvenile fish as well as providing features for anglers to fish as well. The provision of cover for fish reduces stress which in turn will enhance the health of the fish stock.

Floating Islands can minimise re-stocking costs and improve sporting opportunities by decreasing mortalities from direct predation and by providing refuges, which reduce the mortality associated with stress and predator avoidance. The provision of spawning habitat increases natural recruitment and reduces the disease risks associated with restocking.

Floating Islands allow fishery managers to actively manage fisheries; they are fully mobile and do not obstruct activities such as seine netting.

Floating Islands help to reduce the incidence of blue-green algal blooms and the potential associated human health risks, attached to the release of toxins by the algae.

Floating Islands provide shade thereby restricting the sunlight available to algae and at the same time they actively soak up the nutrients that algae rely upon for food.

The modular design can be adapted to a variety of different scenarios. The structure is fabricated from UV resistant PP tubing, sealed at their ends and connected with a simple push-through plastic bolt. An HDPE grid base is attached to the tubes with cable ties. Vegetation is provided by the use of pre-established coir pallets placed on the grid base.
