【考案の詳細な説明】
本考案は、海苔、もずく、赤貝の稚貝等の養殖
袋に関する。[Detailed Description of the Invention] The present invention relates to a culture bag for seaweed, mozuku, young red shellfish, etc.
海苔は秋に養殖網に種付けして、秋から冬に収
穫する。この種付けは、糸状体を培養し、これか
ら放出される胞子を養殖網に付着させるもので、
春から夏に種付け用の貝殻（カキ殻）に糸状体を
繁殖させる。種付けは海中に支柱を立てて養殖網
を張り、網の下に種苗貝殻を入れた容器を多数取
り付ける方法が用いられている。通常は３〜４日
で糸状体から胞子が放出して養殖網に付着し、種
付けは終了する。 Seaweed is seeded in aquaculture nets in the fall and harvested from fall to winter. This seeding involves culturing the filaments and attaching the spores released from the filaments to the aquaculture net.
The filaments are propagated in seed shells (oyster shells) from spring to summer. The method used for seeding is to set up a support in the sea, set up an aquaculture net, and attach many containers containing seedling shells under the net. Normally, spores are released from the filamentous bodies and attached to the aquaculture net in 3 to 4 days, and seeding is completed.
種苗貝殻を入れる容器は、種付けの間に破れな
いこと、及び干潮時に２〜４時間容器が海面上に
露出するが、このときに容器内の貝殻が乾燥しな
いことが必要である。このため容器として従来
は、海水の漏れない合成樹脂製の海苔養殖袋が用
いられている。この海苔養殖袋は、種付け後に回
収されることになつているが、海中に落下するも
のや回収しきれない場合もあるため、海を汚染す
る弊害が生じている。また合成樹脂製の海苔養殖
袋は、袋の補強及び開口を保持するため、針金、
合成樹脂製の棒等を長円形にして開口部に取付け
ることが必要で、このため製造に手間がかかる。 The container in which the seedling shells are placed must not be torn during seeding, and the shells within the container must not dry out during the 2-4 hour exposure to the sea surface at low tide. For this reason, seaweed cultivation bags made of synthetic resin that do not leak seawater have conventionally been used as containers. These bags for seaweed cultivation are supposed to be collected after seeding, but sometimes they fall into the sea or cannot be collected completely, resulting in the problem of contaminating the sea. In addition, synthetic resin seaweed cultivation bags are made of wire,
It is necessary to make a rod made of synthetic resin into an oval shape and attach it to the opening, which takes time and effort to manufacture.
本考案は、湿潤裂断長が１〜７Kmの湿潤強化紙
からなる袋の本体開口部の周囲に、補強用紙を帯
状に接着した通し穴を有する補強部を設けてある
ことを特徴とする海藻又は稚貝の養殖袋である。 The present invention is characterized in that the bag is made of wet reinforced paper with a wet tearing length of 1 to 7 km, and around the main body opening, a reinforcing part with a through hole made of reinforcing paper bonded in a band shape is provided. Or a bag for cultivating young shellfish.
本考案の養殖袋は、使用後に２週間以上海中に
放置されると自然崩壊するので、自然落下した
り、回収しきれない場合でも海を汚染することが
ない利点を有する。 The culture bag of the present invention will naturally disintegrate if left in the sea for two weeks or more after use, so it has the advantage that it will not fall naturally or pollute the sea even if it cannot be recovered.
本考案の養殖袋を製造するための袋紙として
は、厚さ30〜200μm、坪量30〜150ｇ／m2程度で
あつて、湿潤裂断長が１〜７Kmの紙が用いられ
る。湿潤裂断長は、JIS P8135により湿潤引張り
強さを求め、下記式により算出する。 As the bag paper for producing the culture bag of the present invention, a paper having a thickness of 30 to 200 μm, a basis weight of about 30 to 150 g/m 2 , and a wet tearing length of 1 to 7 km is used. The wet tearing length is calculated by determining the wet tensile strength according to JIS P8135 and using the following formula.
湿潤裂断長（Km）＝湿潤引張り強さ（Kg）／Ｂ（mm）
×Ｗ（ｇ／m2）×
1000
ここにＷは試験片の坪量、Ｂは試験片の幅を示
す。特に縦方向及び横方向の湿潤裂断長が１〜７
Kmである紙が好ましい。このような紙で作製した
養殖袋は、海水中でも２週間程度は波にもまれて
も破損することがない。湿潤裂断長が１Km未満の
紙で作製した養殖袋は種付け期間中に容易に破損
してしまい不都合である。また湿潤裂断長が７Km
を越える湿潤強化紙からなる養殖袋では海水中で
の自然崩壊に時間がかかり、特にそれらが回収し
きれない場合には海を汚染するという弊害を生ず
る。 Wet breaking length (Km) = Wet tensile strength (Kg)/B (mm)
×W (g/m 2 ) × 1000 Here, W indicates the basis weight of the test piece, and B indicates the width of the test piece. In particular, the wet tear length in the longitudinal and transverse directions is 1 to 7.
Km paper is preferred. Culture bags made of such paper will not be damaged even in seawater for about two weeks even if they are washed away by waves. Culture bags made of paper with a wet tear length of less than 1 km are disadvantageous because they easily break during the seeding period. Also, the wet tear length is 7km.
Culture bags made of reinforced paper that exceeds moisture content take a long time to naturally disintegrate in seawater, and especially if they cannot be recovered completely, they pose a problem in that they pollute the sea.
湿潤裂断長が１Km以上の紙の製法としては、例
えば耐水性重合体を紙に内添する方法、含浸する
方法、紙を耐水性重合体で被覆する方法が用いら
れる。耐水性重合体で処理することにより、水の
漏出を防止することもできる。補強用紙は前記の
湿潤強化紙をそのまま用いてもよいが、厚さ
100μm以上のものが好ましい。 Paper having a wet tearing length of 1 km or more can be produced by, for example, adding a water-resistant polymer internally to the paper, impregnating the paper, or coating the paper with a water-resistant polymer. Water leakage can also be prevented by treatment with water-resistant polymers. The above-mentioned wet reinforcement paper may be used as the reinforcement paper, but the thickness
Preferably, the diameter is 100 μm or more.
本考案の養殖袋の形状は、四角形に限らず、三
角形、多角形、円筒状、円錐状、角柱状等であつ
てもよい。 The shape of the culture bag of the present invention is not limited to a quadrangle, but may be triangular, polygonal, cylindrical, conical, prismatic, or the like.
以下図面について説明すると、本考案の養殖袋

ことにより形成する。袋本体の開口部には、幅１
〜２cmの補強用紙３を帯状に接着し、通し穴４を
２個ないし数個設ける。 To explain the drawings below, the bag body 1 of the culture bag of the present invention preferably has a side of 10 to 20 cm, and the adhesive part 2 is made of water-resistant adhesive such as polyolefin-based or polyacrylic-based emulsified adhesive. After coating, it is formed by heat-pressing and heat-sealing. The opening of the bag body has a width of 1
A reinforcing paper 3 of ~2 cm is glued in a band shape, and two or several through holes 4 are provided.
本考案の養殖袋を海苔の種付けに使用するに際
