【考案の詳細な説明】
〔産業上の利用分野〕
この考案はアワビ、ウニ、サザエ等の魚介類の
飼育装置に関するもので、人工採苗または天然採
苗されたアワビの稚貝等を高い生存率で成育せし
め、かつ再捕率を高めようとするものである。[Detailed explanation of the invention] [Industrial application field] This invention relates to a breeding device for fish and shellfish such as abalone, sea urchin, and turban shell, and is designed to raise the survival rate of artificially or naturally harvested abalone young. This aims to improve the catch rate and increase the recapture rate.
従来、アワビの稚仔は人工的に採苗され、殻長
が10〜15mmになるまでは人工飼料により飼育槽で
成長せしめて自然界に放流し、成長を待つて再捕
するか、あるいは放流後の生存率を高めるため
に、さらに25〜30mmになるまで人工的な囲いの中
で人工飼料およびまたは天然の海草等を給餌して
飼育し、放流後、成長を待つて再捕されてきた。
Traditionally, young abalone seedlings are harvested artificially, grown in breeding tanks with artificial feed until their shell length reaches 10 to 15 mm, and then released into the wild, waiting for them to grow before being recaptured, or after release. In order to increase their survival rate, they have been raised in artificial enclosures with artificial feed and/or natural seaweed until they are 25 to 30 mm long, and then released and recaptured after waiting for them to grow.
ところが、アワビは普段は穴の中や岩場の裏側
に外敵を避けて潜む習性があり、せつかく人工採
苗し、稚仔に育てあげ、さらに収穫サイズにまで
大きく育つたものが岩の裏に隠れて再捕され難い
といつた問題がある。そして、大きくなつた成貝
ほど隠れ逃げる習性が強く、ますます人手による
収穫が難しくなる。かくして、人工的に育てられ
た成貝はそのまま老体となり寿命を全うし、水産
業の対象から外れてしまうことになる。一説によ
れば、アワビを人工的に育てても収穫される率は
５〜10％にしか過ぎないと言われている。
However, abalone usually hides in holes or behind rocks to avoid predators, so the seedlings are harvested manually, raised to young, and the ones that grow to harvest size are hidden behind rocks. The problem is that it is difficult to be recaptured. The larger the adult molluscs, the more likely they are to hide and run away, making it increasingly difficult to harvest them by hand. In this way, artificially raised adult mollusks become old, reach the end of their lifespans, and are no longer subject to the fisheries industry. According to one theory, even if abalone is grown artificially, the harvest rate is only 5 to 10%.
およそ、栽培漁業の目的は天然の場の効率良く
育て成体となし、再生産のための親体のみを残し
て全て収穫し、食卓に供することにある。しか
し、アワビの場合は稚仔の生育場を良くすればす
るほど、恰好の隠れ家を作ることになり、成体も
過剰に保護されて収穫され難いのが現状といえ
る。 Generally speaking, the purpose of cultivation and fishing is to efficiently grow fish into adults in the natural environment, harvest all but the parent bodies for reproduction, and serve them on the table. However, in the case of abalone, the better the breeding ground for young abalone, the better a hideout they will create, and the reality is that adults are also overprotected and difficult to harvest.
一方、アワビの稚仔はタコ、ヒトデ、イシダ
イ、キユウセンといつた天敵とも言える食害動物
に囲まれているので、アワビにとつてはこれら外
敵から隔離された隠れ家が必要である。 On the other hand, young abalone are surrounded by predatory animals such as octopuses, starfish, sea bream, and snails, which can be considered natural enemies, so abalone need a hideout that is isolated from these predators.
この考案の目的はこのようなアワビなどの生態
を考慮して、自然海域で外敵を防ぎ、稚仔を生存
育成せしめ、成長した後は100％収穫を可能なら
しめる飼育装置を提供することにある。 The purpose of this invention is to provide a breeding device that takes into account the ecology of abalone and other abalones, protects them from predators in natural waters, allows the young to survive and grow, and enables 100% harvesting after they grow up. .
以下、この考案の概要を実施例に対応する図面

きる。 The fish and shellfish rearing device of this invention has a lattice frame body 1 whose outside is covered with a net 9 to prevent escape, and a large number of cages made of hollow cylinders for fixing young or adult fish and shellfish. It is filled with substrate 3. Here, the settlement substrate 3 refers to a substance on which fish and shellfish such as abalone settle and live, and since the entire lattice frame 1 will be salvaged at a later date, it is made of hard vinyl chloride, synthetic resin such as Bakelite, etc. A lightweight one such as one made of FRP is preferable. in this way,
By using the lattice frame 1 as the main body shape of the rearing device and using an artificial hollow cylinder as the settling substrate 3, the overall weight can be reduced, and the lattice frame 1 can be salvaged and grown fish and shellfish can be collected. You can harvest without wasting anything.

逃散を防止する。 The interior of the lattice frame 1 is filled with a large number of fixed substrates 3 made of hollow cylinders so as not to move even when shaken by waves or currents, and a lattice-shaped lid 7 is attached with wires 8 or the like. Further, the entire surface of the lattice frame 1 is covered with a net 9 such as a fishing net having eyes of a size corresponding to the size of the abalone to be raised within the lattice frame 1 to prevent the abalone from escaping.
着定基質３は第２図ａ〜ｅに示すような中空筒

定基質３相互が面と面で密着して非有効面積を生
じるといつたことが少なく、最も理想的である。 By forming the fixing substrate 3 into a hollow cylinder as shown in FIGS. 2a to 2e, the fixing area can be increased and it is also suitable as a hiding place, so that the storage capacity can be increased. Among them, a star-shaped cylinder as shown in FIG. 2e is the most ideal, as it is rare for the fixing substrates 3 to come into close contact with each other surface to surface, resulting in ineffective area.
また、上部の蓋７のほぼ中央には網でできた筒

定基質３は何度でも再使用することができる。 In this way, the protected and cultivated abalone is placed in the lattice frame 1.
The entire lattice frame 1 is lifted to the sea via a hanging ring 4 provided on the upper part of the lattice frame, the lid 7 is removed, the settled substrate 3 is taken out, and the lattice frame 1 is harvested. Of course, the lattice frame 1 and the fixing substrate 3 can be reused any number of times.
格子枠体１としてはFRP（繊維強化プラスチツ
ク）製のものが適するが、十分に防錆処理された
鋼製のものでもよい。 The lattice frame 1 is preferably made of FRP (fiber-reinforced plastic), but may also be made of steel that has been sufficiently rust-proofed.
なお、この考案の飼育装置はアワビに限らず、
ウニ、サザエ等の着定基質を要する水産生物に広
く応用されるものである。 Note that this breeding device is not limited to abalone.
It is widely applied to aquatic organisms that require a fixed substrate, such as sea urchins and turban shells.
次に、この考案の飼育装置の成果を確認するた

ことができる。[Effects of the invention] By using an artificial hollow cylindrical body as a settlement substrate, the weight of the entire rearing device can be reduced, and the lattice frame can be salvaged together. In addition, by raising the entire lattice frame, it is possible to harvest seafood such as abalone, which has grown and is hidden deep between the settlement substrates, without wasting it.
中空筒体からなる着定基質がその内外面に大
きな定着面積を有し、かつ隠れ場所としても好
適であるため、魚介類の収容能力が増大する。 Since the fixation substrate made of a hollow cylinder has a large fixation area on its inner and outer surfaces and is also suitable as a hiding place, the storage capacity for fish and shellfish is increased.
