Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、あさり、蛤、あげまき、タイラギ、赤貝、し
ゃみせん貝等の貝類、海老等の養殖に適した人工養殖床
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an artificial culture bed suitable for cultivating shellfish such as clams, clams, fried oysters, Japanese oysters, red shells, and oyster shells, shrimp, and the like.

〔従来の技術〕[Conventional technology]

有明海等の海浜は干潟からなる泥質層であるため、従来
有効に利用されていなかった。即ち、干潟の利用は、自
然に棲息する海産動物のみで、その生産力利用について
は微々たるものであった。Beaches such as the Ariake Sea are made up of muddy tidal flats, so they have not been used effectively in the past. In other words, the use of tidal flats was limited to the marine animals that naturally inhabited them, and their productive potential was negligible.

そこで、その有効利用を図るため、近年、干潟に海砂を
積み、あさりの種苗を播く養殖床が開発されている。Therefore, in order to make effective use of this water, in recent years, aquaculture beds have been developed in which sea sand is piled up on tidal flats and clam seeds are sown.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

しかし、かかる養殖床は、干潟層に海砂が沈降するため
、毎年、海砂を補充しなければならなかった。However, such aquaculture beds had to be replenished with sea sand every year because sea sand settles in the tidal flat layer.

本発明は上記問題点を解決することができる貝等の人工
養殖床を提供することを目的とする。An object of the present invention is to provide an artificial culture bed for shellfish, etc., which can solve the above-mentioned problems.

〔問題点を解決するための手段〕[Means for solving problems]

上記問題点を解決するため、本発明では、干潟等の泥質
層の上面に椰子繊維等からなる綱体を展設し、同綱体上
に海砂を載せて海砂層を形成して人工養殖床を構築する
ものである。In order to solve the above problems, in the present invention, a rope made of coconut fiber etc. is laid out on the top surface of a muddy layer such as a tidal flat, and sea sand is placed on the rope to form a sea sand layer. This is to construct an aquaculture bed.

〔実施例〕〔Example〕

以下、添付図に示す実施例に基づいて、上記問題点を解
決するための手段を具体的に説明する。Hereinafter, means for solving the above problems will be specifically explained based on the embodiment shown in the attached drawings.

図示するごとく、養殖床は、本実施例では、第１図に示
すように、多数の養殖床ユニット１を干潟等の泥質Ｎ２
に設置して構成している。As shown in the figure, in this embodiment, as shown in FIG.
It is installed and configured.

各養殖床ユニット１は、第２図及び第３図に示すように
、泥質層２上に、周囲に膜質状枠３を連結した網体４を
載置し、同網体４上に海砂層５を載置することによって
構成している。As shown in FIGS. 2 and 3, each aquaculture bed unit 1 has a net 4 on which a membranous frame 3 is connected around the muddy layer 2, and a seawater on the net 4. It is constructed by placing a sand layer 5.

な和、各網体４の面積は、例えば、１００坪ぐらいとす
るのが好ましい。The total area of each net body 4 is preferably about 100 tsubo, for example.

また、網体４は、第２図及び第３図に示すように、海砂

は３〜３Ｑｍｍが好ましく、網の直径は、展設時の作業
性を考慮して１〜５ｍｍとするのが好ましい。In addition, as shown in FIGS. 2 and 3, the mesh body 4 is designed to have an anti-friction effect that prevents the sedimentation of the sea sand layer 5 into the muddy layer 2, and to prevent the intrusion of the giant mantis shrimp. is preferably 3 to 3 Qmm, and the diameter of the net is preferably 1 to 5 mm in consideration of workability during spreading.

また、海砂層５は、好ましくは約３０〜８０ｃｍの厚み
とするのが好ましい。即ち、あさりは、砂層３０ｃｍ程
度に棲息するものであり、あげまき、赤貝は、８０ｃｍ
程度に棲息するからである。Further, the sea sand layer 5 preferably has a thickness of about 30 to 80 cm. In other words, clams live in a sand layer of about 30 cm, and agemaki and red clams live in a sand layer of about 80 cm.
This is because they live in a certain degree.

本発明では、上記のように構築した養殖床上にあさり等
の幼貝を散点し養殖する。In the present invention, young clams such as clams are scattered and cultured on the culture bed constructed as described above.

２から完全に区画されているので、海砂が泥質層２内に
流入するのを防止でき、また網体４は椰子線維等からな
るので、その接触摩擦力によって海砂が沖に向けて流出
するのを防止することができる。In such aquaculture, the sea sand layer 5 is completely separated from the muddy layer 2 by the net 4, which prevents sea sand from flowing into the muddy layer 2, and also prevents the sea sand from flowing into the muddy layer 2. Therefore, the contact friction force can prevent sea sand from flowing out to sea.

さらに、第２図に示す膜譬状枠３に網体４を合体した人
工養殖床は、潮の干満により海水に浸漬し、海砂層５に

たれる。Furthermore, the artificial culture bed, which is made by combining the membrane frame 3 and the net 4 shown in FIG. Conditions are kept.

即ち、満潮時に透水性の良い砂層に網目を通し、底部の
干潟養分が湧昇し、干潮時には、底部の網目を介して密
度の高い泥質が海砂層の海水を貯えることができるから
である。In other words, at high tide, the highly permeable sand layer is passed through a mesh, and nutrients from the tidal flat at the bottom upwell, and at low tide, the dense mud can store seawater in the sea sand layer through the mesh at the bottom. .

〔実験例〕[Experiment example]

本発明にかかる人工養殖床の製作に必要な施設費、維持
管理費及び水揚げ量を、従来の養殖床の場合と比較した
実験結果を、以下の表に示す。The table below shows the results of an experiment in which the facility costs, maintenance costs, and amount of fish landed necessary for manufacturing the artificial culture bed according to the present invention were compared with those of conventional culture beds.

〔発明の効果〕〔Effect of the invention〕

以上述べてきたごとく、本発明では、干潟等からなる海
浜であっても養殖床として有効利用でき、かつ、長期間
にわたって海砂の入れ換えを行う必要がないので、経済
的である。As described above, in the present invention, even a beach made of tidal flats or the like can be effectively used as an aquaculture bed, and there is no need to replace the sea sand over a long period of time, so it is economical.
