Description

【0001】
【発明の属する技術分野】
本発明は、海藻を中心とした海中林を造成するために使用される海中林造成用海藻種苗の生産方法に関する。より詳しくは、損傷の少ない良質の造成用海藻種苗を提供するとともに、造成用構造物に対する取付方に適合した造成用海藻種苗を効率的に提供するための技術に関する。
【0002】
【従来の技術】
この種の造成用海藻種苗に関する原始的な方法としては、海中に自生している海藻をはぎ取って海藻種苗として移植に使用するという方法があるが、そのはぎ取り時に伴う仮根部のダメージにより、海藻種苗として海中へ再移植した場合の成功率は低いものであった。他方、弾性糸からなる芯糸の周囲に一般繊維を配して帯状あるいはロープ状に形成した基体に海藻種苗の胞子を着生し発芽をまって海中に沈設した造成用構造物に取付けるという形態の造成用海藻種苗が知られている(特開昭61−92517号公報)。
【0003】
【発明が解決しようとする課題】
本発明は、海藻種苗の着生率を更に向上し、損傷の少ない良質の海藻種苗が得られ、しかも生産効率を向上し得る海中林造成用海藻種苗の生産方法を提供するとともに、その方法で得られる海藻種苗を造成用構造物への取付方に適合した形態で効率的に提供することを目的とするものである。
【0004】
【課題を解決するための手段】
前記課題を解決するため、発明では、胞子の着生に適した種苗糸等の種苗着生基材に海藻の胞子を着生させて発芽させた後、その種苗着生基材をそのまま担体に装着して更に育成し、仮根部が同担体に付着した後、少なくとも1個の葉状部を含むように前記担体を分割して個々の海中林造成用海藻種苗を形成するという技術手段を採用した。本発明では、先ず、胞子が浮遊する陸上の水槽内等で種苗糸等の種苗着生基材に適宜海藻の胞子を確実に着生させ発芽させた後に、その種苗着生基材ごと担体に装着するので着生率が高いとともに、種苗に適した分布率で担体に装着することができるので、更に海中等において育成して仮根部が担体に付着して仮根部からの葉状部が生長した場合には、良質の海藻種苗が得られる。また、この方法によれば、仮根部が損傷を受けない形で個々の造成用海藻種苗に分割されるので、その点でも良質の海藻種苗が得られる結果、海中への移植の成功率を向上できる。
【0005】
また、種苗糸等の種苗着生基材を介して仮根部が付着した担体を分割して形成した分割片から造成用の海藻種苗を形成したので、海藻種苗を造成用構造物に対して締付バンド等の取付用具を用いて取付ける場合などには、その取付形態に合わせて自由に分割片を形成できるので、海藻種苗の形成作業がきわめて効率的である。延いては、その分割片からなる海藻種苗と取付手段とが相俟って造成用構造物への取付時間の短縮化が図れるので、海藻種苗に与えるダメージを最小限に抑えることが可能である。
【0006】
【発明の実施の形態】
本発明に使用する海藻の種類としては、コンブ目コンブ科に属するツルアラメが好適であるが、コンブ科に限らず他の種類の海藻でも広く適用が可能である。前記種苗着生基材としては、海藻の胞子が着生しやすいものであれば、クレモナ(商品名)等の適宜の種苗糸や帯状のものが好適である。また、担体としては、海藻の仮根部が着生可能なものであればよく、ビニルホースやロープ状などの紐状のものが分割作業が容易であることから好適である。なお、担体の外周面は、仮根部が付着しやすいように凹凸状があるものが望ましい。また、個々の造成用種苗に分割しやすいように、担体として切断に適した素材を用いたり、予め切れ目やくびれを形成しておいてもよい。その担体に対する前記種苗着生基材の装着は、種苗着生基材を担体の外周面に巻付けたり、ストレートに沿わせて接着剤や固定具を用いて固定することにより簡単に装着することができる。なお、仮根部が付着した後、担体を分割する場合には、少なくとも1個の葉状部を含むように分割すればよく、その単位の長さは海藻種苗の装着の仕方等に応じて選択すればよい。
【0007】
【実施例】
以下、図面を用いて本発明の実施例に関して説明する。図1は本発明の一実施例を示した概略説明図である。図中、1は種苗糸等からなる種苗着生基材で、前述のように胞子が浮遊している陸上の水槽内等で適宜の海藻の胞子を着生させ発芽させたものである。そして、例えば1ヶ月程度育成して1〜2mm程度の新芽が形成された頃に取出し、例えば図示のようにビニルホース等からなる中空状の担体2の外周面に装着する。本実施例では、図示のように担体2の外周面に種苗着生基材1を螺旋状に巻付けることにより装着している。この場合、種苗着生基材1をより的確に固定するため、図示しない固定具や接着剤等を用いて要所を固定するようにしてもよい。そして、その状態で、更に海中等において育成することにより、前記種苗着生基材1に着生した胞子の仮根部3が伸長して担体2に着生するようになるとともに、やがて仮根部3から葉状部としての幼体4が形成される。図1はその頃に取出したところを示したもので、本実施例では図示のように1〜3枚程度の幼体4を含むように切断線A〜Dに沿って切断することにより分割片の造成用海藻種苗5を分割形成している。
【0008】
図2〜図4は以上のようにして生産された分割片の造成用海藻種苗5の使用形態を例示した適用状態図である。図2に示した実施例は、例えば造成用構造物を構成する柱体部分に装着可能に構成されたC形の取付リング6の嵌着部7に前記造成用海藻種苗5を嵌着して使用する場合を示したものである。なお、嵌着部7の取付方向を90度回転させ、取付リング6のほぼ全長にわたる長さに担体2を分割して造成用海藻種苗としてもよい。図3に示した実施例は、取付バンド8に前記造成用海藻種苗5の中空状の担体2部分を外嵌した状態で使用する場合を示したものである。本実施例においても取付バンド8の全長に近い長さの造成用海藻種苗を用いることができる。図4に示した実施例は、取付バンド9に挿通支持された保持具10の嵌着部11に前記造成用海藻種苗5を嵌着して使用する場合を示したものである。なお、図2及び図4の場合には、担体2としてロープ状のものを用いた場合にも好適である。また、いずれの実施例においても、造成用構造物の形状や造成条件、コスト等に応じて造成用海藻種苗を構成する前記担体2の長さを適宜選択することができる。
【0009】
【発明の効果】
本発明によれば、次の効果を得ることができる。
(1)先ず種苗糸等の胞子の着生に適した種苗着生基材に海藻の胞子を確実に着生させて発芽させた後に、担体に装着して仮根部を同担体に付着させるように育成するという方法を採用したので、着生率が更に改善され、良質の海藻種苗が得られるとともに、生産効率が向上する。
(2)仮根部が担体に付着した後にその担体部分において分割するようにしたので、仮根部が損傷を受けていない良質の海藻種苗が得られることから、海中への移植の成功率が向上する。
(3)分割片から造成用の海藻種苗を形成するように構成したので、造成用構造物に対して締付バンド等の取付用具を用いて取付ける場合などには、その取付形態に合わせて適宜分割することにより、海藻種苗の形成作業をきわめて効率的に行うことができる。延いては、それらの取付手段と相俟って、造成用構造物への海藻種苗の取付作業の短縮化にも資する。したがって、作業時間の短縮化も相俟って、ダメージの少ない状態で海中へ投入されるので、その後の海藻種苗の生育状態がきわめて良好である。
