本発明は栽培漁業の種苗生産に必要なクロレラ、ワムシ
の培養その他に使用する水上シートタンクに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floating sheet tank used for culturing chlorella and rotifers necessary for seedling production in cultivation and fisheries.
現在栽培漁業の種苗生産は設備として陸上に多くのコン
クリート池を作り、そこで行なわれている。Currently, seed production for fish farming is carried out in a number of concrete ponds built on land as facilities.
所がその池の５０〜５５％は浮化仔魚に与えるワムシお
よびワムシの飼料となるクロレラの培養池に使用されて

のコンクリート池のすべてを仔魚の飼育に充てられるの
で、多額の経費を要する陸上施設の建設規模に対する種
苗生産量は倍増し、投資に対する生産効率を非常に高め
ることができる。However, 50 to 55% of the pond is used for cultivating rotifers to feed the floating larvae and chlorella as feed for the rotifers. If this culture could be carried out at the sea surface, the entire concrete pond on land could be used for rearing larvae, which would double the amount of seedlings produced compared to the scale of construction of land-based facilities, which would require a large amount of money, and greatly increase production efficiency relative to investment. can be increased.
培養の主対象種であるシオミズツボワムシは１７０〜２
６０ミクロン程度の大きさであり、また、クロレラもさ
らに４・形の顕微鏡的大きさであり、また、肥料を添加
するのでこれらを水上で培養するためには水密性タンク
でなければならない。The main target species for cultivation, the Shiomitsu rotifer, is 170 to 2.
Chlorella is about 60 microns in size, and chlorella is also microscopic in size, and since fertilizer is added, a watertight tank is required to cultivate them on water.
このタンクを剛体構造とすると陸上設備と同様あるいは
それ以上の経費や手間を要することとなる。また、水上

性、経済性に優れ、取扱いの容易な栽培漁業の種苗生産
等に通した水上のシートタンクを提供するものである。If this tank were to have a rigid structure, it would require the same or more cost and effort as land-based equipment. In addition, although a flexible sheet structure above the water can save money and equipment, when pumping water out, as the water in the tank decreases, the sides dent inward and the bottom rises, creating an irregular shape. This deformed the tank, making it extremely difficult to pump out the water in the tank, which had the fatal drawback of making it difficult to pump even 50% of the water. The present invention provides a tank with a structure in which when the water is pumped out and the water is reduced, the tank is folded regularly so that the plane becomes a radial star shape as the water decreases, thereby achieving excellent productivity, economy, and easy handling for cultivation and fishing. It provides a sheet tank on water for seed production, etc.

の給排水筒を経て自在に汲み上げることができる。The contents of a rectangular sheet tank in plan view according to one embodiment shown in the drawings will be described in detail below. In Fig. 1, reference numeral 1 denotes a four-split raft in the form of a rectangular frame with a floor plate arranged on the rectangular frame and a buoyant body 2 attached to the lower surface. This small raft 1 has a rectangular frame shape.
A bridge plate 1' is mounted from the center of the inner circumferential side of one side to the center of the inner circumferential side of one opposing side. Further, tension lines 4 for suspending the tank 3 are stretched between the four corners of the inner periphery of the small raft 1, the midpoint of each frame side, and the center of the bridge board 1'. The tank 3 is constructed of a water-impermeable sheet in the shape of a rectangular box, and the top surface is usually closed. Suspension rings 5 are attached to the four corners of the upper edge of the tank 3 and the midpoint of each side, and weights 6 are attached to the four corners and the center of the bottom surface. The weights of the weights attached to the four corners of the bottom of this tank and the weight of the bell attached to the center vary depending on the material of the tank seat and the speed of the current, but the weight in the center is 1/3 of the weights in each of the four corners. A certain amount of weight is sufficient. The tank i is suspended from the tension wire 4 of the small raft 1 with a hanging ring 5 in the direction of its center so that it can be carried freely at the port, and the four corners of the upper green are connected to the small raft 1 by means of springs 7, rubber strings, weights with pulleys, etc. It is connected to each of the four corners of the rectangular frame. A water supply and drainage tube 8 having a cylindrical dragon structure is fitted with iron in the center of the bridge plate 1' of the small raft 1, and water in the tank can be freely pumped up through this water supply and drainage tube.

Since the tank 3 acts in a retracting manner, it remains stationary in the water while maintaining a substantially rectangular box shape as shown in the first diagram. When a water suction tube (not shown) of a pump (not shown) is inserted into the water supply and drainage tube 8 to pump up the water in the tank 3, as the water in the tank decreases, the water pressure outside the tank increases and the side of the tank increases. is pressed inward.

As shown in FIGS. 3a to 3b, its planar shape becomes a four-sided radial star shape as water drains. Since dowels 6 are provided at the four corners of the bottom of the tank, the vertical ridgeline remains vertical. Since the bottom surface is pulled downward by the central wheel weight 6, the side surface shape becomes an inverted pyramid shape as shown in c. According to the results of experiments, with this structure, the water in the tank can be reduced by 9.
It was able to pump up 9% of the water, completely solving the problem of poor drainage in sheet tanks that had not been solved in the past. Generally, when pumping up water for ``succeeding'' when cultivating vermin and chlorella, only 1/4 to 1/3 of the total amount of suspended water is left as the ``original seed'', and not every drop of water is pumped up. Therefore, the sheet tank of this configuration can fully meet the demands. Splash and rainwater intrusion can be avoided by spreading a sheet over the top of the tank. Also, the fourth
If the tank is shaped like a rectangular parallelepiped as shown in the figure, it can be made more efficient depending on the purpose or location. Moreover, it goes without saying that the planar shape may be a polygonal shape other than four corners. The sheet tank of the present invention can be used not only for cultivating rotifers and chlorella, but also for acclimating trout from freshwater to brackish water to seawater, which is a prerequisite for seawater aquaculture.
即ち淡水の排出量と海水の補給量を調節し海水対淡水の
比率を０′１０→３／１０→６′１０→１０／１０と変
化させればよい。That is, the ratio of seawater to freshwater may be changed from 0'10 to 3/10 to 6'10 to 10/10 by adjusting the amount of freshwater discharged and the amount of seawater replenished.
また、同様にして海水で種苗生産した鮎を淡水馴致する
場合にも利用できる。この他、例えば石油等の海面備蓄
用タンクとしても適用可能でその応用範囲は広い。It can also be used to acclimatize sweetfish produced in seawater to freshwater in the same manner. In addition, it can also be used as a sea surface storage tank for petroleum, etc., and has a wide range of applications.
