Solaris Feeders

We've got Solaris feeders working on all sorts of fish farms, at aquaculture colleges, on remote Scottish lochs, keeping salmon fed and helping, to breed carp and trout. These are very well made feeders for the professional but some models are also very suitable for use by koi enthusiast who need to be able to keep their prize fish well fed when they are away at work or on holiday.

The Solaris range of feeders comes up with an answer to all of those questions. These feeders are almost all available for mains or solar power. There are a number of advantages to using the solar powered models: No running costs, no wiring up, no mains power close to water, no power cuts. In fact we've supplied more solar powered feeders than any other - even to places in the north of Scotland where there's a distinct shortage of daylight through the Winter months.

These feeders can be used as stand-alone units or as part of a computer controlled multi-unit system. Send us details of what you want to do and we'll suggest which feeder or feed system best suits your purposes.

We can also supply 3kg and 5kg clockwork feeders that will distribute the feed over a 12 or 24 hour period. Simple but very effective, these feeders are very robust.

Planktonfeeder 2000

Over the past 20 years the Institute for Fish Research in Austria has developed methods for using Frozen Plankton as a feed for freshwater and marine fry. Now successfully running their own hatcheries using this method and also assisting hatcheries elsewhere in the world, the Institute has designed a feeding machine specifically to handle Frozen Plankton. This method of feeding is particularly successful when used on fish fry which are more difficult to rear such as, halibut, arctic char, turbot, grouper.

Planktonfeeder 2000 comprises a portable freezer with inbuilt timing controls providing a timed wash-down of the frozen plankton. This gives a very accurate quantity of feed which can be automatically distributed to up to 16 tanks. Some 160,000 fry can be fed at any one time. Experiments in the use of Frozen Plankton showed that best results were obtained when the feed is handled carefully. Planktonfeeder 2000 was therefore developed for just this purpose - it also cuts down on the manpower required to control feeding.

Results show that the fry mortality rate is significantly reduced when this method of feeding is used. Since the designed working life of Planktonfeeder 2000 is at least 10 years, the cost of the feeder will be rapidly recovered. Frozen Plankton supplies are readily available but training and advice can be provided where customers wish to harvest their own plankton

Planktonfeeder 2000 is available for purchase with complete operating instructions. Consultancy "packages" on a hire or purchase basis can also be supplied. Such packages include on-site training and instruction. This would include specialist advice on plankton harvesting.

Fish Feeders for Koi Enthusiasts

Solaris Fish Feeders have been developed over the past 20 years in a joint operation by the Solaris Company of Austria and the Austrian Institute for Fish Research. Solaris feeders are in operation on fish farms throughout the world and in the most arduous of conditions.

For the koi enthusiasts purchasing a Solaris feeder represents an investment in well-tried and tested equipment which will give a lifetime of use. With the koi keeper in mind we have introduced a "mini" hopper of about 7Kg. Recognising that koi are usually kept in ponds within attractive gardens, we can also supply the feeder and hopper in all green so that the feeder will not stand out like a sore thumb!

How should the koi keeper decide which feeder to order? Ask yourself how long you want to be able to leave your fish to fend for themselves. If it is merely for a day or part of a day then the clockwork feeders will be quite adequate.

Should you wish to leave your fish for a number of days and to be able to control how your fish are fed each day, then the Standard or Interval feeders are your best bet. Add to this the feed hopper of your choice – depending on how much feed you wish to delivery while the fish are unattended, and you have a feeder which will give trouble free operation for many years.


We are often asked whether the solar-powered feeders work on a dull day. These feeders work whenever it is light and do not need sunshine in order to operate. Such feeders are in operation, for example, on remote Scottish lochs where dull weather is often the norm. Solar power has the advantage of requiring no mains power to be fed out to the garden – the power also comes free!
