Definitions
- the present invention relates to a larval incubator for breeding fish larvae, comprising a cylindrical tank containing water, this tank being provided with a device for distributing food, with a device for modifying the rate of gas contained in water, a device for skimming the surface of the water, means for supplying clean or regenerated water and means for discharging used water.
- Known incubation tanks generally have a clean water inlet arranged on their periphery, near the free surface of the water, and an overflow to regulate the water level in the tank.
- Certain models are also provided with a skimming device intended to remove from the surface of the water a film containing lipids and bacteria.
- the farmer can add a degassing device to the incubation tanks used to avoid oversaturation of the gas in the water. All bins are in principle equipped with a food distribution device. The food thus distributed falls into the tank and part of it is eaten by the larvae while the rest is deposited at the bottom of the tank.
- the use of such a device has two shortcomings.
- the larvae which are close to the food source grow faster and at the expense of the others, and one thus obtains a batch of larvae of nonhomogeneous size and on the other hand, the food fallen in bottom of the tank is wasted and can decompose causing degradation of water quality.
- Most of the current tanks have opaque black walls. This characteristic allows the larvae to clearly distinguish their prey thanks to the contrast which facilitates the capture of food.
- the present invention proposes to overcome these drawbacks by providing a simple construction tank, the accessories of which form a removable assembly which is easy to remove, in which the food is not wasted and which makes it possible to maintain the quality of the water constant.
- a larval incubator as defined in the preamble and characterized in that the means for bringing clean or regenerated water into the tank comprise a duct disposed substantially along the vertical axis of the tank, this duct being provided at its base, at least one discharge orifice and associated with an element arranged to generate radial and upward currents in the water of said tank.
- the element for generating currents in the water comprises fins arranged at the bottom of the tank, around a circular crown adjustable in height.
- said conduit comprises at least one tube for supplying clean or regenerated water connected by one of its ends to a source of water supply and by its other end to one of said discharge orifice , said tube emerging near the bottom of the tank above said fins, in the space circumscribed by the circular crown.
- Said supply tube preferably comprises a removable nozzle, said nozzle being provided with the discharge orifice.
- the means for discharging used water advantageously comprise a discharge tube, one end of which is located at the free surface of the water and the other end of which passes through the bottom of said tank and opens out of it.
- the evacuation tube is advantageously screwed to the bottom of the tank.
- Said conduit advantageously comprises several water supply tubes, these tubes being arranged around the evacuation tube and integral with the latter.
- the water supply and discharge tubes, the element intended to generate currents in said water, the device for modification of the gas rate, the skimming device and the food distribution device are integral with each other and form a removable assembly.
- the supply tubes and the evacuation tube are surrounded by a strainer whose top is located above the water level.
- said tank comprises at least one transparent side wall and a dark, opaque and convex background.
- the upper edge of the tank is provided with means for fixing a dark and opaque removable coat.
- FIG. 1 is a vertical sectional view of the incubator according to the present invention.
- FIG. 2 is a bottom view of the element provided for generating Han water currents from the incubator according to the invention
- FIGS 3a and 3b are respectively partial plan views and in section along line II of the element illustrated in Figure 2 and mounted in the incubator;
- - Figure 4 is a top view of the assembly formed by the skimming device and the food distribution device;
- FIG. 5 is a sectional view along the line ⁇ -LT of the assembly illustrated in FIG. 4.
- the larval incubator 10 comprises a cylindrical tank 11 having a bottom 12 and a side wall 13.
- This tank 11 is provided with means 17 for bringing clean or regenerated water, with means 18 for discharging the waste water, a device for modifying the gas level 19 intended to avoid the supersaturation of nitrogen or causing an oversaturation of oxygen in the water, a device 20 for distributing food for the larvae and a skimming device 21 of the water surface. It is also equipped with an element 22 disposed at the bottom of the tank 11 for generating currents in the water of said tank and with a strainer 23, the use of which will be specified below.
- the means 17 allowing the supply of clean or regenerated water to the tank 11 are in the form of a conduit 25 formed for example of six regularly spaced tubes 26. These tubes are arranged vertically so that one of their ends is situated above the free surface of the liquid in the tank, near the device for modifying the gas rate 19 and so that their other end opens out above the element 22 intended to generate currents. At this end, each tube is moreover provided with a removable nozzle 27 (FIG. 3b) comprising a discharge orifice 28. The dimension of the orifice 28 of the nozzle 27 determines the water flow in the tank which allows you to modify this flow rate only by changing the nozzles. This is usually done at larvae start to grow and depends on the type of larva and the size of the tank.
- the means 18 provided for the evacuation of the used water are in the form of a discharge tube 29 disposed in the middle of the tubes 26, parallel to the latter.
- the upper end of this discharge tube 29 is placed slightly below the level of the free surface of the water so as to create a slight depression and draw water from the tank. Its lower end crosses the bottom 12 of the tank and is connected to a discharge pipe (not shown). This end is also provided with a threaded zone 30 (FIG. 3b) allowing the tube to be screwed into an appropriate bore in the bottom 12 of the tank.
- the discharge tube 29 can be connected to the tubes 26 by gluing, by welding or be made in one piece by molding.
- the profiled element 22 provided for generating currents in the water in the tank 11 is in the form of a disc 41.
- This disc is provided, on its upper face, with a circular groove 44 and, on its lower face , of two crowns 42, 43 respectively concentric and nested one inside the other.
- the crown 42 is fixedly mounted on the disc 41 and the crown 43 is arranged to be able to slide inside the crown 42.
- it has oblong openings for its fixing by screws to the fixed crown 42.
- Fins 40 are regularly arranged around the two crowns and have a height greater than the maximum height of these crowns.
- These fins 40 are for example planar and rectangular and are arranged so as to form a constant angle with respect to a radius passing through an identical point of each fin. They are fixed on the disc 41 by bonding or welding. They can also be made in one piece by simultaneous molding of the disc and the fins.
- the bottom of the fins 40 rests on the bottom 12 of the tank.
- the orifices 28 of the tubes 26 opening into the disc 41, in the space circumscribed by the crowns 42, 43, the water leaving these tubes 26 passes under the crowns and is rotated by the fins 40.
- the height of the free passage existing between the bottom of the tank and the crowns 42, 43 determines the speed of the currents in the tank.
- the adjustment of the position of the sliding crown 43 makes it possible to adjust this speed, and to adapt it to the needs of the high larvae.
- the bottom of the tank is convex, it follows an upward helical current of water in the tank.
- This current is beneficial for several reasons. On the one hand, it makes it possible to bring up the surface of the waste which is in the water and which the evacuation tube 29 can suck up and to resuspend in the water the particles of foods which tend to sediment the bottom of the tank, which allows a significant saving of food. On the other hand, it homogenizes the food plankton mixture, which gives the larvae the same chances of feeding and results in the production of a batch of larvae of uniform size. Finally, it allows the renewal of a large quantity of water without the speed of the current being too great and not likely to cause deformations of the spinal column of the larvae. By modifying the shape of the fins, it is in particular possible to optimize their performance.
- the strainer 23 intended to prevent the passage of the larvae into the supply-evacuation assembly is formed by an openwork cylindrical sleeve 31
- Figure 3a covered with a net with meshes of appropriate dimensions to allow the passage of particles which must be disposed of in wastewater.
- This strainer is disposed around the assembly formed by the tubes 26 and the discharge tube 29.
- the sleeve 31 is positioned on the element 22 in the groove 44 provided for this purpose and extends above the level of the 'water.
- the gas rate modification device 19 is formed of a tube 32 containing a substrate 33 of synthetic material which has a large surface promoting gas exchange between water and air.
- This substrate consists, for example, of rods or balls sold under the name "Bioballe” ®. These balls have a large number of cavities and have a large surface. This surface thus allows significant gas exchanges between air and water.
- Two vents 34 formed at the bottom of the tube 32 allow the escape of the gases contained in the water and extracted by the substrate.
- This tube 32 can be plugged by means of a removable cover 50 comprising an opening 51, through which water can be introduced, and an opening 52 for introducing oxygen.
- the vents 34 can be closed by removable plugs 53.
- This device for modifying the gas rate allows two distinct functions.
- the removable cover When the removable cover is removed and the vents 34 are open, the passage of water through the substrate 33 makes it possible to avoid oversaturation with nitrogen, which is harmful for the larvae.
- the removable cover 50 plugs the tube 32, that oxygen is introduced into this tube and that the vents are closed, this device allows an increase in the oxygen level in the water until an oxygen supersaturation.
- This embodiment is particularly advantageous in that it allows the raising of a larger number of larvae in the same volume of water.
- the device 19 is screwed onto the discharge tube 29.
- the device 20 provided for the distribution of food is formed of a tube 35 connected to a tank (not shown) containing plankton.
- This plankton is in solution in the tank and is introduced into clean water or regenerated according to the needs of the larvae contained in the tank, for example by means of a valve whose opening is controlled automatically or by means of a peristaltic pump. This device is fixed below the gas rate modification device 19.
- the skimming device 21 is intended to "skim" the surface of the water in the tank. Indeed, it frequently forms on the surface, a fatty film containing lipids and bacteria which prevent the inflation of the swim bladder of fish.
- This skimming device 21 consists of three substantially horizontal suction tubes 36 (FIGS. 4 and 5) arranged on a ring 37. This ring can be fixed by three sliding tabs 38 to the device for modifying the gas rate 19.
- the skimming device can float on the surface of the water and the three fixing lugs 38 can slide freely so that this skimming device always remains at the ideal level, even if the water level in the tank varies slightly.
- Each suction tube 36 has a nozzle 39 directed substantially towards the center of the ring 37.
- the latter is mounted so that the level of the free surface of the water arrives approximately in the middle of the tubes 36. From the pressurized air is introduced through the nozzles 39 which creates a vacuum and sucks the particles disposed on the surface of the tank towards the center of the ring 37. These particles are then sucked by the vacuum created by the evacuation tube 29 and eliminated by the latter.
- the upper edge 14 of the tank is moreover provided with fixing means 15 of a removable coat 16 black.
- fixing means 15 can for example be a gripping strip 24 fixed on the upper edge 14 of the tank and cooperating with a complementary strip fitted to the upper edge of the removable coat 16. In this way, this coat can easily be placed around the tank 11 or removed therefrom.
- These fixing means 15 could also be composed of hooks and eyelets or any other known mechanical connection means.
- the removable mantle 16 All the accessories of the incubator except the removable mantle 16 are linked to the evacuation tube 29, itself screwed to the bottom of the tank. This allows a particularly simple disassembly when it is necessary to change or clean a part.
- the strainer 23 can be removed very easily by unscrewing the gas rate modification device 19.
- This incubator thus makes it possible to have at will a transparent tray or a dark and opaque tray.
- the coat 16 can for example be removed during the first days of larvae rearing so as to allow light to pass through the walls of the tank, then when the disorderly swimming phenomenon disappears, this coat 16 can be placed around the tank. to make it easier to locate food.
- it is possible to adjust the flow of water in the tank as well as the speed of the current. It is therefore possible to adapt as well as possible to the type of larvae raised in order to guarantee optimal breeding of the larvae and a high success rate.
