Description

本発明は、アサリ等の潜砂性二枚貝を陸上で生産する方法に関する。  The present invention relates to a method for producing submarine bivalves such as clams on land.

商品として流通するアサリ等の潜砂性二枚貝の多くは天然産であり、各地域により漁業権設定、漁獲サイズ規制が存在するため漁業者以外が生産に参入することが難しく、資源量の動向は自然発生に頼る部分がほとんどであった。  Most of the submarine bivalves such as clams that are distributed as commodities are naturally produced, and it is difficult for non-fishers to enter production due to the establishment of fishing rights and fishing size regulations in each region. Most of the parts depended on the natural occurrence.

産地においては、人工種苗を生産して2mm程度の稚貝を地蒔き方式で生息地に放流する例もあるが、小さすぎるため海流等の自然環境に定着率が左右され、その効果が漁獲量の回復という形では現れていないところが多い。  In production areas, there are cases where artificial seedlings are produced and juveniles of about 2 mm are released into the habitat by ground-spreading methods. There are many places that have not appeared in the form of recovery.

また、近年は資源量に対する過剰な漁獲や過去例を見ない捕食生物による甚大な被害が増えるなど、稚貝の定着が難しく資源の再生産が促進されにくい状況にある。  Also, in recent years, overfishing relative to the amount of resources and enormous damage caused by unprecedented predators have increased, making it difficult for young shellfish to settle and promoting resource reproduction.

その他、自然環境下においては、場所によって貝毒や化学物質の汚染が発生するなど、市場へ安全に安定的に供給することが困難な状況もあり得る。  In addition, in the natural environment, there may be situations where it is difficult to provide a stable and safe supply to the market, such as shellfish poisoning or chemical contamination depending on the location.

人工種苗においては、多くの研究機関で生産の取組がなされているものの、屋内の水槽で飼育し、その餌料も人工培養されたものであり、生産経費と労力を多分に必要としていた。  Artificial seedlings have been produced by many research institutes, but were raised in indoor aquariums and their food was also artificially cultivated, requiring a lot of production costs and labor.

近年は人工稚貝を様々な方法で、小規模若しくは実験的規模で養殖する取組が行われ始めている。  In recent years, efforts have been made to cultivate artificial larvae in various ways on a small or experimental scale.

特許文献1では、砂を敷いた容器に稚貝を入れ、網で覆い海水中に吊るすことで貝を育成する養殖方法が開示されている。  Patent Document 1 discloses a culture method in which young shellfish are put in a container laid with sand, covered with a net, and hung in seawater to grow shellfish.

この方法においては、天然の環境に餌料等を委ねることで給餌に係るコストが削減され、容器を使用することで管理生産を行う利点がある。  In this method, the cost for feeding is reduced by entrusting food and the like to the natural environment, and there is an advantage of performing management production by using a container.

また、特許文献2においては、様々な設定を施して陸上の装置内で二枚貝を養殖する方法が開示されている。  Patent Document 2 discloses a method of cultivating bivalves in a land device with various settings.

特許文献2に記載されている方法は、装置内に粒砂体を二枚貝の殻長の3倍〜5倍の厚さに敷き、水深を0.5cm〜5cmの範囲内とし、飼育水を1cm/s〜25cm/sの範囲内の流速で注入し、栄養塩を添加しながら特定の付着性微細藻類を粒砂体表面に繁茂させて、それを餌料とすることで養殖する方法である。  In the method described in Patent Document 2, a grain sand body is laid in the apparatus to a thickness of 3 to 5 times the shell length of a bivalve shell, the water depth is within a range of 0.5 cm to 5 cm, and the breeding water is 1 cm. Injecting at a flow rate within the range of / s to 25 cm / s, a specific adherent microalgae grows on the surface of the grain sand body while adding nutrients, and is cultivated by using it as a feed.

この方法においては、陸上の容器内で付着性微細藻を繁殖させることで給餌の問題を解決し、陸上管理下で養殖することができる。  In this method, the problem of feeding can be solved by breeding adherent microalgae in a container on land, and it can be cultivated under land management.

しかしながら、特許文献1に記載の発明においては、使用する天然の稚貝が漁獲サイズの規制等により市場に流通することは稀であることから、別途に人工稚貝を調達する必要があり、この方法が広く普及した場合、今後は稚貝の市場供給が課題となる。  However, in the invention described in Patent Document 1, it is rare that natural larvae to be used are distributed to the market due to restrictions on catch size, etc., so it is necessary to procure artificial larvae separately. If the method becomes widespread, the supply of juvenile shellfish will become an issue in the future.

また、養殖する設備を大量に製作する必要があるほか、飼育期間中は海上での様々な維持労力が必要となり、特に容器へ藻等の付着が起これば容器内の二枚貝の生存に欠かせない通水機能が喪失するため、定期的に設備を水中から引き上げて清掃する必要がある。しかも、海上に設置するため、成果はその海域の環境に依るところが大きく、天候により作業ができないことも予想される。  In addition, it is necessary to produce a large amount of equipment for aquaculture, and during the breeding period, various maintenance efforts are required at sea. Especially if algae adhere to the container, it is indispensable for the survival of bivalves in the container. It is necessary to periodically lift the equipment out of the water and clean it. Moreover, because it is installed on the sea, the results largely depend on the environment of the sea area, and it is expected that the work cannot be done due to the weather.

また、特許文献2に記載の発明においては、特殊な装置を製作する必要があるほか、各種設定の範囲内で管理しなければならず、効果を更に上げるためには人工灯の設置も必要であるなど、大量生産を行うには維持管理コストが装置数に比例して増大することが予想される。  In addition, in the invention described in Patent Document 2, it is necessary to manufacture a special device, and it must be managed within the range of various settings, and an artificial lamp must be installed to further improve the effect. For example, for mass production, the maintenance cost is expected to increase in proportion to the number of devices.

しかも、水深の関係上、海水或いは汽水を使用している場合、屋外に設置した装置内に雨水が入り込み塩分濃度の急激な低下が起こる恐れと、気温変動に対応した飼育水温度の管理のため、機器増設が必要になる場合もあり、直ちに対処しなければ収容生物の生存が危ぶまれる。  Moreover, due to water depth, when seawater or brackish water is used, rainwater may enter the equipment installed outdoors, which may cause a drastic drop in salinity and management of breeding water temperature in response to temperature fluctuations. In some cases, additional equipment may be required, and the survival of the contained organisms will be jeopardized if not handled immediately.

本発明は、アサリ等の潜砂性二枚貝を陸上で簡便に生産し、稚貝或いは成貝を市場に安定的に供給する方法を提案するものである。  The present invention proposes a method for easily producing submarine bivalves such as clams on land and stably supplying juvenile or adult clams to the market.

本発明のアサリ等の潜砂性二枚貝の生産方法においては、屋外の飼育池又は飼育槽(図1参照)中の底砂として中粒砂を使用し、底質改良のため浄化作用を持つバチルス属、ラクトバチルス属等の有用微生物、及び細かく粉砕した貝殻を混ぜることにより、底質を自然環境に近づけることができ、粉砕した貝殻の成分が貝の成長を促進させる作用がある。  In the method for producing submarine bivalves such as clams of the present invention, bacillus having a purification action for improving sediment quality by using medium-sized sand as the bottom sand in outdoor breeding ponds or breeding tanks (see FIG. 1). By mixing useful microorganisms such as the genus and Lactobacillus and finely crushed shells, the bottom sediment can be brought close to the natural environment, and the components of the crushed shells have the effect of promoting the growth of shells.

本発明のアサリ等の潜砂性二枚貝の生産方法においては、屋外の飼育池又は飼育槽の底砂は30cm±5cmの厚さとすることを特徴とする。これにより、貝を掘り起こす際に、底の土と砂が混ざることを防ぐ作用がある。  In the method for producing submarine bivalves such as clams according to the present invention, the bottom sand of the outdoor breeding pond or breeding tank is 30 cm ± 5 cm thick. This has the effect of preventing the bottom soil and sand from mixing when the shellfish are dug up.

本発明のアサリ等の潜砂性二枚貝の生産方法においては、屋外の飼育池又は飼育槽の水深は50cm〜80cmの範囲とすることを特徴とする。これにより、水量を多く取ることで屋外での雨水流入による塩分濃度低下に対する緩衝幅を広げることができる。  In the method for producing submarine bivalves such as clams of the present invention, the water depth of the outdoor breeding pond or breeding tank is in the range of 50 cm to 80 cm. Thereby, the buffer width | variety with respect to the salt concentration fall by rainwater inflow outdoors can be expanded by taking much water quantity.

本発明のアサリ等の潜砂性二枚貝の生産方法においては、一定方向へ向かう水流を5cm/s〜15cm/sの範囲とすることを特徴とする。これにより、池内が攪拌されて微細藻の繁殖を促進させる作用がある。  In the method for producing submarine bivalves such as clams of the present invention, the water flow toward a certain direction is set in the range of 5 cm / s to 15 cm / s. Thereby, the inside of a pond is stirred and there exists an effect | action which promotes reproduction of a micro algae.

上記により、海水或いは汽水を使用している場合に、降雨による塩分濃度の低下を注入水により調節できる作用があり、また屋外のため、人工光を使用せずに太陽光による光合成にて、貝の餌となる植物プランクトンを自然増殖させることができることから、週に1〜2回の種藻の投入で安定的な餌料環境を維持する作用がある。
In the method for producing submarine bivalves such as clams according to the present invention, the breeding water inlet is installed at a location far from the drain outlet, the amount of injected water is adjusted according to the amount of rain, and the culture is periodically cultured in the breeding water. By feeding phytoplankton, the feed in the pond is propagated.
According to the above, when seawater or brackish water is used, there is an effect that the decrease in salinity due to rain can be adjusted by injected water, and because it is outdoors, the shellfish can be synthesized by sunlight without using artificial light. Since the phytoplankton serving as the feed can be naturally grown, there is an effect of maintaining a stable feed environment by introducing seed algae once or twice a week.

本発明のアサリ等の潜砂性二枚貝の生産方法によれば、自然界における一般的な場合と比較して同程度の優れた成長をし、陸上で生産するため収穫も容易であり生産量も予測が立てやすくなる効果を奏する。
また、一般的な屋内稚貝生産と比べて管理が粗放的であり、屋外であるため太陽光により餌料となる植物プランクトンが池内で自然繁殖することから、屋内生産に比べて生産経費も抑えられることがわかった。
According to the method for producing submarine bivalves such as clams of the present invention, it grows at the same level as the general case in the natural world, and since it is produced on land, it is easy to harvest and predicts the production amount. Has the effect of making it easier to stand up.
Also, compared to general indoor juvenile production, the management is more extensive, and because it is outdoors, phytoplankton, which serves as a feed by sunlight, propagates naturally in the pond, so production costs can be reduced compared to indoor production. I understood it.

本発明は、閉鎖性環境にて生産が可能であることから、資源減少した地域の貝を用いて採苗することで、血統保存しながら資源回復用の放流用途への利用が期待できる。  Since the present invention can be produced in a closed environment, it can be expected to be used for release for resource recovery while preserving the pedigree by collecting seedlings using shellfish in areas where resources have been reduced.

また10mm程度まで育てた稚貝は養殖種苗用途への利用も期待でき、養殖形態に合わせて貝のサイズを用意できる利点も備える。  In addition, juveniles grown up to about 10 mm can be expected to be used for cultured seedling applications, and have the advantage that the size of shellfish can be prepared according to the cultivation form.
