Description

Device and enclosure for farming aquatic organisms
The present invention relates to a facility for fish breeding or general farming of aquatic organisms, as stated in the introduction of claim 1 , together with a fish breeding enclosure for such a facility.
Background of the invention
Utilities for fish breeding normally have large net bags, held floating in the sea attached to buoyancy means or comprising groundbased basins. The floating bag has economic advantages as long as the fish breeding facility is not exposed to any damaging influences from sea water, i.e. from contagious matter and parasites. In such cases, facilities are undesirable and may lead to huge losses. Onshore facilities offer little flexibility and can not normally be moved.
Sea farming is a quickly developing industry on an international level. Lately, a limiting factor has been finding suitable locations for fish breeding both onshore and offshore, and it is assumed that the competition for water resources and locations will increase. Accordingly, this will cause an increase in land costs and suitable sea locations have to be utilized to their maximum.
Development in the international sea farming industry tend towards fish breeding in an industrial way, having increased investments where there are good opportunities for production control, biomass control, i.e. fish quantity and size and water quality, where the feeding is well adapted to the biomass and temperature/quality, and systematic sorting and slaughter. Accordingly, the production costs decrease and orderbased production may be possible. Moreover, there are constantly larger requirements for traceability in the production of both feed and fish.
Both authorities and customers require fish breeding to take place without unnecessary pollution. Accordingly, stronger requirements regarding spill control and possible cleaning of waste water is implied. Generally, waste feed and excrement are regarded as resources, which may be processed and used for other purposes.
Both labour inspectors and workers themselves make stronger demands for safety , health and environment at their workplace. In Norway there is now a problem in recruiting workers to the sea farming industry, partially related to the working environment. The risk in investment in a production facility is large if the facility may only be used for one kind of fish feeding and in addition can not be moved. Investors in industrial facilities have put focus on the lifetime costs of the facility, productivity and flexibility instead of the investments alone. Furthermore, the investors are engaged in controlling the establishment costs and construction costs .
From UK patent application 2 153 191 (Vangen 1984), it is known to split up a fish breeding facility in more sections by constructing a frame system comprising simple frames each able to support a smaller net bag. Still, it does not make the fish less vulnerable, and does not make the facility more movable, to move away from algae etc.
From UK patent application 2 163 331 (Jensen 1984), it is known to construct the the fish breeding enclosures in the form of box shaped net bags comprising floating mantel bodies, such that several such enclosures may be coupled together. This solution has not provided any great advantages for fish breeding utilities .
Object of the invention The main object of the invention therefore is to create a floating fish breeding facility meeting the requirements presented above. Moreover, it is important not to produce polluting waste and to avoid possible damaging influence from the surroundings, for example dangerous algea or parasites in the sea.
The invention
The invention is characterised by the features defined in the characterising part of claim 1. The invention may be used for breeding of different marine organisms in addition to fish, for example shrimps and shells.
The fish breeding facility described is created to take advantage of being seabased without being exposed to those disadvantages that sea location have so far caused. More details of the invention are specified in the claims 2 to 10, wherein claim 9 specifies a best mode of a fish breeding basin in the form of a floating facility according to the invention. The invention is further described with more details below, with an example of a preferred embodiment. Further detailed information about functions and advantages are given with reference to this embodiment.
A facility capable of being delivered as a module-based prefabricated "house" , including pumps, feeding pipes and an eventual cleaning plant/mud treatment system will be competetive even to a higher price than utilies purchased partwise. Accordingly, a movable, environmentally friendly facility is created, giving opportunities for production control and satisfying the wishes and requirements of both authorities and investors.
Example The invention is further described refering to the drawings, where
Fig. 1 shows a pictorial view illustration of an embodiment according to the invention, and
Fig. 2 shows in detail the embodiment of a fish breeding basin according to the invention.
The facility in the example illustrated in fig. 1 is based on a floating structure 11 , also forming the foundation of a supporting structure 12. The floating structure 11 has a central, longitudinal bar 13, having a number of perpendicular protruding piers on each side, in the example there are five piers 14 - 18 on one side and five opposite piers 19 - 23 on the other. On each side, between adjacent piers, an opening 24 having free broadwise access from the outside is formed. At their distal ends, the piers 14 - 23 form foundations for two side walls 25, 26 built up with a lower beam 27, pillars 28 and an upper beam 29. Together with two end walls 30 and 31 , supported by the respective outer pier pairs 14 and 19 and 18 and 23, the side walls 25, 26 support a ridge roof 32. The walls and roof are partly omitted in the drawing to give a better overview of the building.
The inner frame work of the walls and the buildings are shaped to contribute to the total strength of the floating structure.
The openings 24 between the pairs of piers, in the example equal in size, e.g.. 11 x 11 meters, contain floating units of fish breeding basins for fish and other aquatic organisms. Such a floating unit 34 is shown in the example, having a floating ring 35 and an octagonal fish breeding basin 36 placed and fastened inside the floating ring. A floating unit 37 is shown together with a floating ring 38 and four octogonal fish breeding basins 39 - 42 assembled inside. The assembled fish breeding basins may be used for fry and small fish, while the large ones may be used for fish soon finished for slaughter. The floating structure 11 serves as a carrier for various service equipment, such as pumps for water supply and for removal of pollution etc. from the basins. Moreover, it may be equipped with a cleaning unit 43 in the central area, that may be biological based or have any other known design.
In fig. 2 an example of the floating unit 34 according to the invention is shown in detail. It has a framwork of steel pipes 44 supporting to outer floats 45, 46 at every corner and an inner float 47 in every corner, thereby forming an octagonal inner room for a fish breeding basin 48, i.e. of glass-fibre reinforced plastics. The fish breeding basin 48 has an upper area broken inwards to reduce the water line area. At every corner a couple of fenders 49 are fastened, i.e. made of rubber blocks, to avoid damage while towing in and out of the place between the piers.
The fish breeding basin 48 is provided with submerged bottom, coupled to a drain hose 50 with a connection pipe 51 at one side edge. The purpose is to have the opportunity to separate breed remainders and faecals (mud) for cleaning and/or recycling. Correspondingly, on the inner side of the feeding basin an inlet spigot 52 coupled to a feed tube (not shown) is fastened for supplying water to the basin.
At every corner in the floating unit, a rising bollard 53 is anchored for mooring or towing the floating structure.
The fish breeding facility according to the invention gives opportunities for rearing under controllable conditions. This fact has major importance with regard to diseases and pollution. Another important advantage is the modularization of the fish breeding facility. The individual floating units may be adapted for different operation requirements, such that the same facility may be rearranged for different operations without considerable, additional costs. Since the facility is less vulnerable to illness, the assurance costs will also be reduced.
Modifications
The floating structure and the roof may be made of elements that are made and transported separately and may be releasably connected at one place of operation. Accordingly, in case towing is impossible, it is possible to perform disassembly and transportation of elements.
The floating unit 34 may be modified in different ways. As mentioned, four smaller breeding basins 39 - 42 (fig. 1) may be inserted. This opportunity increases the flexibility and the facility may now practically and quickly adapt to other operation forms, i.e. change from salmon breeding to smolt production. The floating units 34. 37 may also be formed from breeding basins in the shape of tight fabric bags extending farther down in the water than shown. Removal of remainders and mud at the bottom may also be done by means of a submerged draft tube.
As will be apparent, the floating structure may also be turned around, having an enclosed open ring with inwardly protruding piers, or a facility having several main parts or bars with piers joined together, e.g. in a honeycomb structure. However, the illustrated strucmre is believed to be the most favourable. The floating units may also be formed as self-supporting units, e.g. made of glass fibre plastics, strengthened by means of suitable supporting materials.
Generally, the floating structure and the belonging parts may be made in a suitable way from known materials, such as steel, aluminium, plastics, plastic-coated fabric, sheetings and composites.
Primarily, the floating units 34 are used for breeding of aquatic organisms as confirmed above. But some units in a facility may be designed for other purposes. They may be used as feed storage or be equipped with storage tanks for fish, mud or waste products. Slaughter equipment may also be placed on such a floating unit. Another field of use is for placing pumps and water handling equipment.
