Moreover, diatoms and haptoalgae have been considered to be difficult to stably produce for a long period of time in the field of aquaculture, especially seed and seedling production. In general, for cultivation of feed organisms, seed algae are grown in flasks and the like, and then batch-cultured in a water tank of several liters to several m 3 and cultured. Diatoms,
Growing haptoalga requires a large amount of light. When the culture device is irradiated with light from outside, the amount of light is insufficient. Protozoa and the like are easily mixed. Long-term stable production is difficult.

る。こうした対応は、魚介類の種苗を生産する現場では
実際には実用化できないのが現実である。However, the fluorescent lamp has a limited light quantity when its size is small. In the method of disposing the fluorescent lamp in the center of the culture tank, the transmission distance of the light emitted from the light source is eventually restricted. Therefore, a long fluorescent lamp and a vertically long culture tank are used. The shape of the culture tank becomes complicated if a large number of luminous bodies are arranged in a small size in order to uniformly irradiate light in the culture tank or to irradiate a sufficient amount of light. It is a reality that such a response cannot be practically used on the spot where fish and shellfish are produced.

There is an example of providing a ~ 1000 liter polycarbonate water tank.
In particular, the number of cases in which a sodium lamp or a large halogen lamp is installed just above a water tank and culture is performed under a high light intensity is increasing. Halogen lamps are nearly monochromatic and can emit intense light. However, although a halogen lamp is good as a light source, it has a drawback of emitting high temperature. The temperature inside the thermostatic chamber rises due to the heat generated by the halogen lamp, and the water temperature in the water tank rises accordingly. If the temperature inside the constant temperature chamber is to be kept constant, an excessive facility for controlling the heat retention is required, and a large amount of electricity is required to operate the facility.

A sufficient amount of culture water is introduced into the culture tank 1 near the upper end, and necessary nutrients are added together with the seed algae therein. When the halogen lamp 11 is turned on, the light emitted from the halogen lamp 11 reaches the peripheral wall of the culture tank 1, but is reflected inside by the reflecting mirror, and
It is efficiently trapped inside. Thereby, the seed algae efficiently activates photosynthetic activity. Photosynthesis requires carbon dioxide. Open the carbon dioxide cylinder 18,
1. Introduce carbon dioxide into the culture tank 1 through a carbon dioxide pipe 10. Adjustment of the inflow amount of carbon dioxide is performed by adjusting the opening of the carbon dioxide solenoid valve 22 while monitoring with the first flow meter 23.

The air whose flow rate has been adjusted is blown from the culture blower 19 to the halogen lamp 11 via the hexagonal branch pipe 26 and the inside of the column 13. Such air pushes hot air around the halogen lamp 11 to the outside air of the sheath tube 8. The temperature control mechanism 20
The temperature detection end 9 receives the temperature signal generated by detecting the temperature of the culture water, adjusts the opening degree of the hexagonal branch pipe 26, and adjusts the amount of air distributed to each of the six sheath pipes. Most of the heat generated by the halogen lamp 11 is thus prevented from increasing the temperature of the culture water. The water temperature in the culture tank is
It is desirable to control the water temperature within a range of ± 2 degrees of the optimum water temperature of the predominant species algae. The temperature change of the culture water can thus be maintained within ± 2 degrees.

A CO 2 mixed gas having an ideal concentration whose concentration has been adjusted is fed into the culture water. Cooling device 31
Continuously feeds cooling water cooled to a predetermined temperature into the constant temperature jacket 17 and makes a round in the constant temperature jacket 17,
It is returned to the cooling device 31 again. Thereby, the heat absorbed by the culture water as a part of the heat generated by the halogen lamp 11 is absorbed again from the culture water, and the temperature of the culture water is kept constant.
When the stirring shaft 6 is rotated by the stirring motor 5, the water in the culture tank 1 flows, and the water temperature is evenly distributed.

ましい。The culture tank 1 does not need to be limited to a transparent water tank in which metal foil is wrapped around the periphery. For example, a metal tank whose inside is substantially mirror-finished may be used. In cooling the halogen lamp 11, air may be supplied continuously or intermittently. It may be linked to a water temperature sensor, or there is a method of linking with a timer and sending air over time at regular intervals. Since the halogen lamp is provided with an infrared reflecting film that returns infrared light to the filament and transmits only visible light, the spectral distribution characteristic is 400 to 800 nm. On the other hand, the light absorption characteristics of algae are 400 to 500 nm and 650 to 700 nm.
It is. Therefore, it can be said that the halogen lamp is closer to an ideal wavelength than a fluorescent lamp having a spectral distribution characteristic of 500 to 600 nm. The inner surface of the culture tank has a specification that can reflect light uniformly, that is, has a mirror finish, and a halogen lamp is installed in the culture tank. Irradiation is maintained. Some halogen lamp products cut UV and IF unnecessary for algae culture and release heat to the rear. Such products are particularly preferred for the present invention.

よい。When air is supplied from the air supply side of the flow path partitioned by the flow path partition wall 13a, the air is blown out from the upper and lower openings, and the halogen lamp 11 is inserted into the sheath bulb 8b.
Wipe out the heat around. This air is then discharged to the outside air along the exhaust-side flow path in the support column 13. Note that the sheath ball 8b may be provided with both left and right wings in each of the upper and lower stages, instead of the single wing as shown in FIG. 4 in each of the upper and lower stages.

ようにすることが好ましい。In the case of the third embodiment, when the column 13 is rotated by the rotary motor, the sheath ball 8b becomes a rotating blade of the rotating machine and stirs the inside of the culture tank 1 at each of the upper and lower stages. In this case, even if the stirring shaft 6 having the stirring blades 7 is not separately provided, there is an effect that the temperature in the culture tank can be uniformly and uniformly distributed. In a case where a halogen lamp was used as a light source (Japanese Patent Application Laid-Open No. 8-38159), irradiation was performed from outside the culture tank, and in a case where diatoms were continuously cultured (Japanese Patent Application Laid-Open No. 56-96690). This is also a method in which light is irradiated from outside the culture tank in a culture tank made of a transparent material. This is completely different from the culture apparatus of the present invention. In addition, the light transmittance of the culture water may vary depending on the culture time of the algae, and the optimal amount of growth may vary depending on the type of the algae. For this reason, it is preferable that the light amount of the halogen lamp can be freely changed.

で20度〜59度まで上昇した。EXAMPLES Examples will be described below, but the present invention is not limited to these examples. [Example] A feed algae culture apparatus as shown in FIG. 1 was provided using a culture tank having a capacity of 10 liters to grow feed algae. FIG. 5 is a diagram showing a change in water temperature in the culture tank, and FIG. 6 is a diagram showing a change over time in the concentration of feed algae. In FIG. 5, □ indicates a case where one halogen lamp was used and constant temperature water was circulated through the constant temperature jacket 17, but the cooling air was not sent to the halogen lamp 11 to control the temperature of the culture tank. 2 shows the change over time in the water temperature in the culture tank. It increased from 20 degrees to 59 degrees in 270 minutes.

ことが分かる。The black circles indicate the case where constant temperature water is circulated through the constant temperature jacket 17 and cooling air is also fed into the halogen lamp 11. No increase in water temperature was confirmed, and it was found that the function as the culture device was sufficiently exhibited.
FIG. 3 shows a specification in which light can hardly be reflected, that is, a case where a feed algae is grown using a culture tank that is not mirror-finished (that is, a conventional method). A fluorescent lamp or a large number of light emitters are arranged at the center. Chitoceras, a kind of dietary algae, was cultured and the change over time in cell density was examined. The open circles indicate the results of culturing bait algae in the culture tank 1 as shown in FIG. 1 formed according to the culture tank of the present invention, and examining the changes over time of the cells. It can be seen that the high density is stably maintained as compared with the case of (1).

なるという事態が防止される。According to the present invention, a halogen lamp surrounded by a transparent sheath with a gap as a light source is installed as a light source in a culture tank on the inner surface capable of uniformly reflecting light, and the culture solution is heated by the halogen lamp. Since a mechanism that can introduce cooling air into the sheath to suppress the temperature rise is provided, the production efficiency per light amount and per volume of the culture device main body is high, and the peripheral equipment can be made more compact. Further, it is possible to provide a feed algae culture apparatus capable of continuously and stably cultivating feed algae. In this case, it is possible to prevent a situation in which a large amount of fluorescent lamps are supplied and the amount of light is still insufficient, or a situation in which the structure of the culture tank is complicated and the effective volume occupying the entire apparatus is reduced.
