Description

  The present invention relates to an aquatic organism activation mat, and more particularly, to an aquatic organism activation (marine organism activation) mat that is effective in a closed sea area / culture farm. Here, the marine organism activation mat will be mainly described as an example, but the aquatic organism activation mat of the present invention can also be applied to freshwater aquaculture.

  In recent years, due to marine pollution, especially in closed sea areas such as aquaculture farms, poor growth of cultured seafood, and an increase in prevalence and mortality have become problems.

  In order to solve these problems, it is carried out (administered) with a bioactive agent / drug etc. mixed with feeding.

  For example, Patent Document 1 discloses a herbal medicine composition for adding to a feed of cultured fish characterized by including a herbal medicine component to promote the growth of cultured fish, and Patent Document 2 discloses a herb. Each of them has been proposed a growth promoter for use by adding to a seafood feed characterized in that

Furthermore, Patent Document 3 shown below exists as prior art document information using stevia as a plant activation component that is typically used as a material (raw material) of an activation active component (bioactive component) for aquatic organisms in the present invention.
Japanese Patent Laid-Open No. 11-169099 Japanese Patent Laid-Open No. 2002-360186 JP-A-10-233468

  In view of the above, the present invention is intended to promote growth of aquatic organisms such as seafood, seaweeds, and crustaceans that are not described in the above-mentioned patent documents and reduce the prevalence and mortality. It is an object to provide an aquatic organism activation mat that can be produced.

  The aquatic organism activation mat of the present invention solves the above problems by the following configuration.

An aquatic organism activation mat in which a granule containing an active ingredient for activation of aquatic organisms (physiologically active ingredient) is filled in a liquid-permeable bag body,
The active active ingredient (physiologically active ingredient) is selected from one or more of plant finely pulverized product (usually 80 mesh under: about 175 μm or less), plant extract (extract), and extract liquid crystal powder Consisting of or active as a plant active ingredient,
The granulated material is granulated by adding a natural binder as appropriate.

  Here, by filling the water-permeable packaged body in the form of a granule containing a plant active ingredient appropriately combined with a finely pulverized product of a plant and a plant extract or extract crystal powder, the active ingredient is put into water. The outflow rate (dissolution rate), that is, the immediate effect and the delayed effect can be appropriately adjusted. In addition, since the active ingredient is composed of or is mainly composed of a vegetable active ingredient, it is less susceptible to spoilage than animal active ingredients, has excellent shelf life, and has a relatively long expiration date (drug efficacy period). Become.

  Furthermore, since it is the structure which fills this granulated body in a water-permeable bag body, it is excellent in handleability, and also the said preservability is further improved by packaging the surface with a moisture-proof film.

  Moreover, as shown in the said patent documents 1 and 2, compared with the case where it mixes with the feed of feeding, it can control outflow of an active ingredient also in the semi-closed sea area like the ocean, and the active ingredient in a required part can be suppressed. Elution can be secured and high-efficiency utilization of the active active ingredient becomes possible (no waste).

  The liquid permeable bag can be formed of a nonwoven fabric. By forming with a non-woven fabric, the thickness can be easily adjusted as compared to the woven fabric, and the water permeability (effective component permeability) can be easily adjusted as compared with the woven fabric.

  The plant material having the activation active ingredient can be stevia. Stevia can promote the reduction of morbidity and mortality by antioxidant action and histamine detoxification action in addition to the general activation action of aquatic organisms.

  Specifically, the composition of the granule is a compounded composition in which the active ingredient data contains 5 to 50 parts of stevia extract with respect to 100 parts of stevia leaf and / or stem finely pulverized product. The natural binder 0 to 10 parts may be added to 100 parts of the component material.

  By setting it as the said composition, ie, adjusting the ratio of a stevia extract and a natural binder, the speed | rate which the active ingredient (medicinal ingredient) of a stevia elutes in water (dissolution diffusion) can be adjusted.

  The mixing ratio of the natural binder-free granulated body and the natural binder-containing granulated body is the former / the latter (mass ratio) = 0/10 to 10/0. By adjusting the mixing ratio, immediate effects, delayed effects, and leveling of medicinal effects can be achieved according to the type and health state of marine organisms (aquatic organisms) for activation.

  The natural binder can be gluten (wheat flour). Gluten itself is a vegetable protein that effectively acts as a nutrient source for aquatic organisms.

  The aquatic organism activation mats having the above-described configurations are used by being arranged at appropriate intervals in an aquatic organism ranch (culture farm) when aquatic organisms are cultured.

  The active ingredient data used in the present invention is a blended composition containing 5 to 50 parts by weight of stevia extract with respect to 100 parts by weight of stevia leaf and / or stem pulverized product, and 100 parts of the active ingredient data. On the other hand, the aqueous bioactivator to which 0 to 10 parts by mass of the natural binder is added can be put into the marine ranch as it is.

  Hereinafter, embodiments of the present invention will be described in detail. In the present specification, “parts”, “%” and the like representing the composition are mass units unless otherwise specified.

  The aquatic organism activation mat of the present invention activates aquatic organisms, and is particularly used for an aquaculture farm (ocean farm) or the like.

  Here, taking the case of aquaculture as an example, in seawater aquaculture, fish such as Thailand, yellowtail, yellowtail and pufferfish, shellfish such as oysters and pearl shells, seaweed such as sea bream and seaweed, and crustaceans such as prawns In freshwater aquaculture, carp, eel, rainbow trout, and ayu can be listed.

  The first feature of the present invention is that a liquid-permeable bag is filled with a granulated body containing an active ingredient (bioactive ingredient) for aquatic organisms.

  The activation active ingredient is selected from one or more of a finely pulverized plant (usually 80 mesh under: about 175 μm or less), a plant extract (extract: essential oil) and the extract crystal powder. It consists of or consists mainly of plant-based active ingredients.

  The plant active ingredient is not particularly limited as long as it gives activity to aquatic organisms. For example, examples of plant materials include stevia and those having the same activation as stevia, and further, various herbal medicines described in Patent Document 1 and / or various kinds described in Patent Documents. It may be mainly herbs. However, as far as the present inventors know, there is no substance having an activation ability and medicinal effect corresponding to stevia.

  Furthermore, as the active active ingredient, in addition to the above-mentioned botanical active ingredient, animal active ingredients, and mineral ingredients such as calcium and iron, materials, and the like described in Patent Documents 1 and 2, etc. Further, a phosphorus adsorbent described in Patent Document 3 and the like can be appropriately blended.

  The form of the granulated body (granules) is an arbitrary form corresponding to the granulating method, such as a spherical shape, a cylindrical shape, a prismatic shape, a truncated cone (cone shape), or the like. And the magnitude | size shall be 1-9 mm, desirably 3-7 mm. If the pellet (granular shape) is too small, the dissolution rate will be high when it is put into water, and it will be difficult to obtain the required sustained drug efficacy. Conversely, if it is too large, the dissolution rate will be slow and necessary when put into water. It is difficult to obtain an effective immediate effect.

  The granule of the present invention is produced, for example, as follows when the plant material having an active ingredient is used as stevia.

  In a specific embodiment of the stevia granule, 5 to 50 parts (preferably 10 to 40 parts) of a stevia extract is blended with 100 parts of a stevia leaf and / or stem finely ground material. It is set as a composition and it is set as the composition which mix | blended 0-10 parts (desirably 0-7 parts) of gluten (flour) with respect to 100 parts of active ingredient data as a natural binder.

  Examples of natural binders other than gluten include plant mucous substances (ex. Troolloi, agar, alginic acid, carrageenan, pectin), plant rubber substances, hemicellulose (ex. Glucomannan, arabogalactan) and the like.

  Specifically, a mixture of each of these component mixtures appropriately added with water using a general-purpose kneading granulator (extrusion type) and pellets (for example, 1 to 5 mmφ × 1 to 5 mmL) (Water content 8-12%) is produced.

  In addition, the form of the water-permeable bag body emphasizing the granulated body is usually a planar shape from the viewpoint of storage and handling properties, but may be any shape such as a cubic shape, a tetrahedron shape, a rod shape, and a strip shape.

  In the case of a planar shape, it is usually a rectangular size or a square shape having a planar size of 10 to 50 cm on a side. In addition, from the standpoint of hanging properties, the length can be about 1 m when it is in the shape of a rod or strip. In this case, it can also be set as a division | segmentation chamber suitably in a longitudinal direction.

  Moreover, although a woven fabric may be sufficient as a water-permeable package body, a nonwoven fabric is used. If the non-woven material is a biodegradable material, no recovery work is required. For example, as the biodegradable polymer, synthetic polymers such as poval, polyester, and polyether, and those derived from natural polymers such as cellulose, lignin, chitin / chitosan, alginic acid, and amylose can be used.

  And the aquatic organism activation mat of the said structure is arrange | positioned at an appropriate space | interval in an aquatic organism farm (culture farm). The arrangement interval varies depending on the type of active active ingredient and aquatic organism, the size of the mat, the amount of active active ingredient filling, etc., but in the case of a stevia mat in the examples described later, and as in the examples described later, It is also possible to put a plurality of them and hang them on a basket.

  And the aquatic organism activation granule which is not filled in the above-mentioned water-permeable bag body, that is, the active ingredient contains 5 to 50 parts by mass of stevia extract with respect to 100 parts of stevia leaf and / or stem finely pulverized product. Of course, the composition is composed or composed of the main component, and the natural binder 0 to 10 parts is added to 100 parts of the active ingredient, as shown in Patent Documents 1 and 2. You can also

  In addition, the Example currently performed from October 7, 2003 in Tokumei, Yukyu-cho, Oku-gun, Okayama Prefecture is demonstrated.

  (1) Each active ingredient data granule of gluten-free type and contained type was prepared as follows.

  10 parts of Stevia extract ("JBB Stevia Extract" manufactured by JBB Stevia Laboratories) and 2 parts of strong powder are added to 100 parts of Stevia's stem and leaf pulverized material (matcha tea: 80 mesh under) and the water content is 10%. A gluten-containing type stevia granule was prepared as a pellet (5 mmφ × 5 mmL) using a general-purpose kneading granulator, which was adjusted before and after.

  (2) About 20 g of the above stevia granule was filled into a non-woven fabric (made of polyester) bag body, and heat-sealed and closed to prepare an aquatic organism activation mat (stevia mat) 14 (planar shape abbreviation: 10 cm × 14 cm × 1 cmt).

  A total of 60 stevia mat-containing ridges 18 (see FIG. 2) in which six stevia mats 14 of each example and comparative example were put in a net ridge 16 were prepared.

  Twenty pairs of these stevia matted heels 18 connected to the heel suspension string 20 at intervals of about 1.5 m were prepared. Then, each set of three stevia mat-containing tubs is divided into 20 pairs of aquaculture tubs (plane size: 18 m × 8 m) 22 with the bottom stevia mat-containing tubs 18 positioned at a depth of about 5 m. Hanging. It should be noted that a shell connecting string 24 in which 20 cultured shells 23 are connected to each other as shown in the figure is suspended from the cultured trough 22.
