Abstract

Automatic device (20) for feeding fish in a fish cage with a feed bin (3) which guide the feed down into a feed bag (9) with a feeding device (4) for distribution of the feed in the fish cage, where the feed bag (9) and the feeding device (4) is under the water surface and the feed, being based on either wet feed, soft feed or gel feed, is released from the feeding device (4) at a set depth in the fish cage.

Description

Automatic feeding device
The present invention relates to a device for automatic feeding of fish in fish cages.
Automatic feeding devices for fish cages exist in different designs adapted according to specific parameters like the nature of feed, the species of the fish, etc. Automatic feeding devices on the market today are mainly based on the use of dry feed (dry pellets) and the feeding is carried out on the water surface. This technology is not desirable for feeding of pellets based on wet feed, soft feed or gel feed which should be stored and handled together with water (fresh- or seawater).
Another important condition is that some fish species prefer the feed "served" on a certain depth and not at the surface.
Previously automatic feeding devices have been used for wet feed, but not based on feeding of wet pellets. This technology was based on a pellet machine being placed by/above the fish cage and the pellets being produced and dropped directly into the water surface of the fish cage. This technology cannot be used just like that for the feeding of readymade pellets based on wet feed, soft feed or gel feed.
There exists a need for a controlled and automatic feeding of readymade pellets for fish feed based on wet feed, soft feed or gel feed. An automatic feeding device in this connection should comprise a complete concept which makes it possible to store the pellets submerged in sea- or freshwater as well as a controlled and automatic feeding under water (submerged).
This is achieved with the automatic feeding device according to present invention as it is defined by the features of the claims.
The invention will be described in more detail below in connection with some embodiments and with reference to the drawings, where figure 1 shows an automatic feeding device according to the invention seen from one side, figure 2 shows a vertical cross section along the line C-C on figure 1, figure 3 shows the automatic feeding device according to present invention in a perspective view, figure 4 shows a first embodiment of the feeding device, figure 5 shows a second embodiment of the feeding device, and figure
6 shows an embodiment of an opening/closing unit where 6a is the unit exploded, 6b is fully closed and 6c is fully open.
The automatic feeding device 20 according to present invention comprises floats 1 with a deck 2 on top on which a feed container 3,9 is arranged. The feed container is in communication with a submerged feeding device 4. The feed container comprises a feed bin 3 in communication with a feed bag 9. From the feed bin 3 being above the water surface the feed is guided down into a feed bag 9 which is fully submerged in water. The feeding device 4 releases a controlled amount of feed which falls by its own means gently down towards a feed plate 6 which is located below and in a distance from the outlet of the feeding device 4. Thus, the feeding device places the feed on the feed plate 6. The feeding device 4 can typically comprise a feed screw 13 or a opening/closing unit 17, but may have different embodiments of know art. Underneath the feeding device 4 there can be arranged a feed spreader 15 to improve the distribution of the feed which is released to fall down on the feed plate 6 below, i.e. the feed falls by its own means out of the feeding device rather than being pushed. The feed bag 9 is in the above embodiment made of liquid permeable material or has a liquid permeable design, i.e. fine meshed/woven netting which allows for the water to circulate, but retain the feed pellets. This will lead to that the surrounding water will mix with the feed, which is important to maintain the properties of the wet feed.
At least one feed sensor 7 in communication with at least one control unit 10 through at least one cable 11, which is placed on the feed plate 6 register the amount of feed on the plate and give feedback to the control unit for supply of feed. A speed monitor 8 register the rotation of the screw 13 or the opening/closing unit 17 in the feeding device 4 and control its speed according to the registrations of the feed sensors 7.
The automatic feeding device 20 according to present invention thereby supply the feed onto the feed plate 6 under the water surface and the fish eat the feed from the feed plate situated at a suitable depth.
Sensors 12,16 are monitoring the amount of light and fresh- or seawater temperature for optimal feeding of the feed and to find the optimal feeding cycles according to the appetite of the fish. The screw 13 or the opening/closing unit 17 in the feeding device 4 comprise preferably an upper part which act as a stirrer 18 to ensure that the wet feed do not clot but get a gentle handling during feeding. The stirrer 18 can rotate together and with the same speed as the screw 13 or the opening/closing unit but in the above embodiment the stirrer 18 rotate independently to reduce clotting of the feed pellets. To increase the amount of feed the fish eat when it is "dark", the automatic feeding device may be equipped with lights 12.
The automatic feeding device can also operate by predefined feeding cycles through the control unit 10 where the feed is allowed to fall to the sea- or freshwater bed. However, with the feed plate 6 and the possibility to control the amount of released feed, the feeding becomes more economical..
