【考案の詳細な説明】
本考案は増殖護岸、特に潮溜り利用の海洋生物
の増殖護岸に関するものである。[Detailed Description of the Invention] The present invention relates to a seawall for breeding marine life, particularly a seawall for breeding marine life that utilizes tidal pools.
従来の護岸工は、海岸に加わる物理的な力に対
抗する事に全力を注いで来た。しかし、特に物理
的に大きな力がかからない内湾部や、港内におい
ても、消波効果と土止めのみを考えた護岸工がな
されているにすぎない。 Conventional seawall construction has focused its efforts on countering the physical forces applied to the coast. However, even in inner bays and ports where large physical forces are not applied, revetment works are only constructed with consideration only for wave-dissipating effects and earth retention.
護岸建設にあたつて特に海岸に生息する、多種
多様の生物の生態系は、全く考慮されていない場
合が大部分である。生物の立場より見れば、従来
の護岸工は、生態系をコンクリートで蹂りんして
いるものに他ならない。 In most cases, when constructing seawalls, the ecosystem of the wide variety of creatures that live on the coast is not taken into consideration at all. From the perspective of living organisms, conventional seawall construction is nothing more than encroaching on the ecosystem with concrete.
ところで、天然海岸、特に磯や干潟は、有用水
産生物を含む、多くの生物の生活基盤であり、か
つまた繁殖の場所である。これらの“場”の存在
は、沖合かなたの生物群にまで影響を及ぼすもの
であり、従つてこれら生物群の一部を利用してい
る沿岸漁業にも肯献しているものである。 By the way, natural coasts, especially rocks and tidal flats, are the living base of many organisms, including useful aquatic organisms, and are also breeding sites. The existence of these "fields" has an impact on the biological communities far offshore, and therefore also supports the coastal fisheries that make use of some of these biological communities.
本考案の目的は護岸建設にあたり磯や干潟に形
成される潮溜りを人工的に作りこれによつて水産
生物の増殖を行うようにした海洋生物増殖護岸を
得るにある。 The purpose of the present invention is to obtain a seawall for the propagation of marine life by artificially creating tidal pools formed on rocks and tidal flats when constructing a seawall, thereby allowing marine life to proliferate.
本考案の海洋生物増殖護岸はその上面前方の角
に斜め下方に延びるくぼみを形成したブロツクを
海浜等に多数前記くぼみが上向きとなるよう上下
に積重して設けて成ることを特徴とする。 The marine life propagation seawall of the present invention is characterized in that a large number of blocks each having a depression extending diagonally downward in the front corner of the upper surface are stacked one on top of the other on a beach or the like so that the depressions face upward.
以下図面によつて本考案の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.

面前方角５を斜めに削除して下段ブロツク３のく
ぼみ２に日光が直射されるようにする。 In the present invention, as shown in FIGS. 1 and 2, a large number of blocks 3 such as square blocks 3 are formed on a rocky shore or a tidal flat 1 with a rectangular depression 2 extending obliquely downward at the front corner of the upper surface thereof. The revetment 4 is formed by stacking the recesses one above the other so that they face upward, and the uppermost recesses 2 are below the sea level at high tide, and the lowest recesses are at a higher level than the sea level at low tide. be configured. Note that the front corner 5 of the lower surface of the block 3 is obliquely removed so that sunlight is directly irradiated into the recess 2 of the lower block 3.
本考案海洋生物増殖護岸は上記のような構成で
あるからくぼみ２内に常に海水がたまり、即ち潮
溜りとなり下記のような効果が得られる。 Since the seawall for breeding marine life of the present invention has the above-described structure, seawater always accumulates in the depression 2, forming a tide pool, and the following effects can be obtained.
ａ 浅く、日光の良く当る静隠な潮溜りは沿岸の
多くの種類のイソギンチヤク、小型甲殻類、各
種巻貝、フジツボ、カキ、イガイ等の水棲生物
にとつて、良好な棲み場所である。Shallow, well-lit, quiet tidal pools are good habitats for many types of coastal sea anemones, small crustaceans, various snails, barnacles, oysters, mussels, and other aquatic creatures.
ｂ 潮溜りの機能により幼魚・稚魚期の魚類にと
つて餌料生物となる水棲生物が産出され、その
結果、餌料要因により魚類が集まる。b. The function of tidal pools produces aquatic organisms that serve as food for young and juvenile fish, and as a result, fish gather due to the food factor.
ｃ 日光の良く当る浅い潮溜りはアマモ、ホンダ
ワラ類等の海草・海藻類にとつて良好な生息空
間である。潮溜り内は、干潮時、海中より隔離
されるのでその期間は、大型魚類による捕食を
受けない。c. Shallow tidal pools that are well exposed to sunlight are good habitats for seaweed and algae such as eelgrass and sargassum. The inside of the tidal pool is isolated from the sea during low tide, so it is not preyed upon by large fish during that period.
ｄ 潮溜り内に増加した付着生物や藻類による栄
養塩類の吸収及び有機懸濁物の除去がされ良好
な水質を維持することが期待出来る。d) It is expected that the increased sessile organisms and algae in the tide pool will absorb nutrients and remove organic suspended matter, thereby maintaining good water quality.
尚、前記くぼみ２の内周面全面に幅10mm程度
の溝を設ければ、この溝によつて付着生物が付
着しやすい。 Incidentally, if a groove with a width of about 10 mm is provided on the entire inner circumferential surface of the recess 2, sessile organisms can easily adhere to the groove.
