20
years' experience in the field of global plankton research and fingerling production with
natural plankton and years of tests under different environmental conditions in marine and
fresh water, are the basis of the new "UWG- Solar cage system". The production
method is based on plankton feeding in the natural environment like: lagoons, bays,
fjords, lakes and large ponds, by means of attracting the organisms using a lamp located
in the center of fine meshed submerged nets. Mainly Copepods and Cladoceres - but also a
variety of other zooplankton organisms are photo sensitive and steadily swarm into the
cages towards the light source. |

POLYMER COATED POLYESTER NETS for cages This special polymer (PVC) coated polyester (PET) net is very strong and stable, but also flexible. The nets are 100 % stronger than conventional nylon nets, are highly UV-resistant, suitable for seawater and need no antifouling. They need about 90 % less maintenance and have fewer escapes than nylon nets. The live-time of this nets with continuous use in fresh water is up to 30 years. The material is available on coils with a width of 3,6 m with a mesh size of 5 mm, and 5,0 m wide with a mesh size of 20 and 40 mm. With a weight of 450-790 g/m2 the cages need no lead sinkers. We deliver finished cages or also the material on coils.

PRECISION CLOTHS for aquaculture and hydrobiology Precision woven screening
fabric is a highly specialized monofilament fabric, characterized by precisely defined and
controlled, consistent and repeatable material properties s.a.: mesh size, thickness,
tensile strength, dimensional stability, cleanliness etc.). This fabric program includes
precision sieves of different material strengths and offers a narrow mesh grading between
20-2000 micrometer and therefore fulfills all requirements of today's aquaculture and
hydrological needs. Appropriate sieve fabrics are offered per running meter and as
standard or customized products, such as filter-, dip-, hatching-, cage- and
plankton-nets.

SHADING SHEETS AND PROTECTION NETS made of polyethylene Shades and nets are made from UV-stable polyethylene material with a shading density of 50-85 % to protect fish and ponds from light and birds. The sheets which let water (from rain) to drain off, are available on coils from 1,5 and 3,0 m width and can be manufactured wider with extra strong hem and eyes. For pricing always the width of the coil is calculated. We also deliver bird protection nets with a mesh size of 15 - 150 mm. |
TRAPS made from plastic This easy to handle and maintenance free plastic traps have been tested in practice and are suitable for both professional and sport fisherman. Features such as a new shape and correct coloring are the result of fishing expertise's. A favorable price/performance rate ensures highest economy in use. Of course the traps are saltwater and corrosion resistant and also resistant to crabs and other pests. This traps (with exchangeable components) have a wide inlet opening and an integrated bait basket in the closed end cap. The traps are specially suitable for catching eels, but can also be used for other fish species as well as crayfish. This traps are delivered complete with sinker weight for submerging, which guarantee that the trap is always positioned with the upper closed side on top, which in turn created a protection shelter for the animals.
