Composition for improvement of chlorosis and malnutrition of shellfish farming using fish sauce waste

The present invention relates to a composition for improving chlorosis in seaweed farming and nutrient deficiency in shellfish farming using fish sauce waste, and more particularly, contains a large amount of nutrients such as phosphate, ammonium salt and nitrate, and the nutrients are slowly released to improve seaweed and shellfish culture. The present invention relates to a composition for improving chlorosis and nutritional deficiencies in aquaculture farming using fish sauce waste, which is effective in improving the chlorosis of shellfish.

The annual production and production amount of farmed seaweed in Korea was insignificant, not exceeding 50,000 tons in the 1970s. From 2017/10 to 2018/5), the production area was 10.18 million books and the production volume was 16.791 million (Ok, 2011).

Currently, almost all laver is produced in aquaculture, and it was recognized as an expensive food in the past when the production of laver was low. In addition, exports of 300 million dollars were achieved in 2015, and as a single item among domestically produced marine products, it can be said to be an export item that represents the second highest export amount after tuna. It has grown rapidly in a short period of time, such as reaching $ 200 million, $ 300 million in 2015, and $ 500 million in 2017.

However, in winter, the growing season of seaweed, the color of seaweed turns yellow and growth is slow, resulting in laver yellowing, which eventually causes the seaweed to drop out of the net. , 2008; Kawamura, 2012; Tanda and Harada, 2012; 2013).

Currently, the damage caused by the yellowing of seaweed in Korea is 2010.10. ~ 2011. 3. : Chungnam, Jeonbuk, Jeonnam West (181,000 books, about 30 billion won), 2017.10. ~ 2018. 3. : Chungnam, Jeonbuk, Jeonnam Goheung (108,000 books, about 29.8 billion won), 2021.11. ~ 2022. 4.: Seocheon, Chungcheongnam-do (production decreased compared to the previous year due to the decrease in nutrients), 2021.12. ~ March 2022: Haenam, Jeollanam-do (approximately 3,000 hectares of seaweed farm, approximately 16.2 billion won), etc.

On the other hand, fish sauce (fish sauce), a traditional fermented seafood product in Korea and a representative processed product of South Chungcheong Province, is produced by fermenting fish sauce for more than 6 months using fish bodies such as canary and anchovies. As this rises, the production of fish sauce is increasing.

However, fish sauce waste (a.k.a. “poop”) generated after processing fish sauce is industrial waste and requires treatment by specialized companies. Due to high unit cost, illegal dumping and landfill neglect are prevalent, leading to soil contamination, odor generation, and pest breeding. Environmental and economic damage, such as urban landscape damage, is getting serious.

1 is a photograph showing a composition for improving chlorosis in seaweed farming and nutrient deficiency in shellfish farming using fish sauce waste prepared in Example 1 of the present invention.

Hereinafter, a preferred embodiment of the present invention and the physical properties of each component will be described in detail, but this is to be explained in detail so that a person having ordinary knowledge in the art to which the present invention belongs can easily practice the invention, This is not meant to limit the technical spirit and scope of the present invention.

The composition for improving the chlorosis of seaweed culture and nutritional deficiencies in shellfish farming using fish sauce waste according to the present invention is composed of fish sauce waste and yellow soil, and 1 to 300 parts by weight of ocher may be mixed with 100 parts by weight of fish sauce waste. Considering the conditions, it is preferable to mix 60 to 150 parts by weight of loess with 100 parts by weight of fish sauce waste.

The fish sauce waste is rich in nutrients such as ammonium salt, nitrite, nitrate, phosphate and silicate, and serves to improve the yellowing of seaweed and shellfish caused by lack of nutrients. The type of fish sauce waste is It is not particularly limited, and any nutrient salt such as ammonium salt, nitrite, nitrate, phosphate, and silicate as described above can be used, but canara fish sauce and anchovy fish sauce are preferably used.

In general, seawater with seaweed farms contains 0.01 mg/L of ammonium salt, 0.001 mg/L of nitrite, 0.025 mg/L of nitrate, and 0.006 mg/L of silicate, although it varies depending on the region, and dissolved inorganic nitrogen is about 0.035 mg/L. It contains L, but the yellowing phenomenon of seaweed or shellfish, especially among seaweed, frequently occurs under the condition that the dissolved inorganic nitrogen content is 0.07mg/L.

On the other hand, the fish sauce waste contains 60 to 62 mg/L of ammonium salt, 0.03 to 0.04 mg/L of nitrite, 0.3 to 0.4 mg/L of nitrate, 5.5 to 6.0 mg/L of phosphate, and 0.15 to 0.25 mg/L of silicate, although this varies depending on the type of fish sauce. It contains L and dissolved inorganic nitrogen of 61 to 62.5 mg/L, so it can improve the yellowing of seaweed such as seaweed and shellfish caused by lack of nutrients.

At this time, the fish sauce waste may be used after being solidified through drying, and the solidified fish sauce waste may be used by being coated on the surface of various carriers in addition to the loess.

60 to 150 parts by weight of the loess is mixed, and when mixed with the moisture contained in the fish sauce waste, it serves as a binder that imparts viscosity, so that the composition for improving nutritional deficiencies in seaweed farming and shellfish farming using fish sauce waste is in various forms. Not only does it play a role in enabling molding, but it also serves to improve the chlorosis of seaweed or shellfish because it contains nutrients such as ammonium salt, phosphate, and nitrate in loess itself.

If the content of the ocher is less than 60 parts by weight, the above effect is insignificant, and if the content of the ocher exceeds 150 parts by weight, the content of fish sauce waste is relatively excessively reduced. It is undesirable because of reduced efficacy.

At this time, the loess is preferably made by mixing a first loess powder having a particle size of 0.000005 to 0.001 millimeter and a second loess powder having a particle size of 0.005 to 0.1 millimeter, and the second loess powder is mixed with 100 parts by weight of the first loess powder. More preferably, it is made by mixing 140 to 160 parts by weight of ocher powder.

When ocher powders having different particle sizes are mixed as described above, the space between the second loess powder having a large particle size is filled with the particles of the first ocher powder, thereby providing a composition for improving the chlorosis of algae and shellfish with excellent mechanical strength. there is.

The first ocher powder is removed from the foreign substances of ocher collected in the natural state, and sieved 5 to 10 times with a fine sieve having a pore size of 0.001 mm, and the ocher powder particles passing through a fine sieve having a pore size of 0.000005 mm. It is made of ocher powder particles that are not passed through a fine sieve, and the second ocher powder is removed from foreign substances in ocher collected in a natural state and sieved 5 to 10 times through a fine sieve with an air gap of 0.1 mm. Ocher powder The particles are again passed through a fine sieve having a pore size of 0.005 mm to obtain unpassed ocher powder particles.

If the content of the second loess powder is less than 140 parts by weight or exceeds 160 parts by weight, the agglomeration between the particles of the first ocher powder and the second loess soil powder is reduced and the bonding strength is reduced due to excessive voids between the particles, so seaweed and The mechanical properties of the composition for improving yellowing of shellfish are lowered, and the water absorption rate is increased, resulting in lowered water resistance.

Therefore, in the loess used in the present invention, it is most preferable that the first loess powder and the second loess powder are mixed in a weight part of 100:150, and the first loess powder and the second loess powder are put into a stirrer and mixed at 500 to 500 It is more preferable to prepare by stirring for 1 to 2 hours at a speed of 1000 rpm.

In addition, the composition for improving the yellowing of seaweed and shellfish using fish sauce waste according to the present invention may further contain 5 to 10 parts by weight of kelp extract based on 100 parts by weight of the fish sauce waste. The binding force of each component constituting the composition for improving chlorosis is further improved to improve mechanical properties, and due to the water resistance of kelp extract, the composition for improving chlorosis in seaweed culture and nutrient deficiency in shellfish culture using fish sauce waste is developed in seawater. It is not easily decomposed and can release nutrients for a long period of time.

The kelp extract is prepared by mixing 20 to 50 parts by weight of kelp with 100 parts by weight of purified water and heating for 10 to 30 minutes at a temperature of 90 to 95 ° C. The kelp extract prepared through the above process contains a large amount of mucilage components. The binding force is further improved due to the mucilage component, and water resistance can be improved because the mucilage component does not dissolve well in water.

At this time, if the content of the kelp extract is less than 5 parts by weight, the above effect is insignificant, and if the content of the kelp extract exceeds 10 parts by weight, the content of fish sauce waste or loess is too low compared to the kelp concentrate, so seaweed and shellfish The effect of improving the yellowing phenomenon may be reduced.

In addition, a coating layer for controlling the release rate of nutrients may be further formed on the surface of the composition for improving the chlorosis of seaweed and shellfish using fish sauce waste according to the present invention. The coating layer contains phosphate and ammonium salt contained in fish sauce waste And forming a coating layer made of one selected from the group consisting of rosin, starch, and oil to a thickness of 0.5 to 2 millimeters on the surface of the composition for improving the yellowing of algae and shellfish so that the release of nutrients such as nitrate proceeds slowly. It is done.

The coating process is not particularly limited, and one selected from the group consisting of rosin, starch, and oil, which is a raw material of the coating layer, is applied to the surface of the composition for improving chlorosis of seaweed farming and shellfish farming nutritional deficiency using fish sauce waste molded in various shapes. It can be done by spraying or by impregnating one selected from the group consisting of rosin, starch, and oil with a composition for improving chlorosis and nutrient deficiencies in shellfish farming using molded fish sauce waste.

When the coating layer is formed through the above process, since the release of nutrients contained in the composition for improving chlorosis and nutritional deficiencies in seaweed farming using fish sauce waste proceeds slowly, nutrients are released over a long period of time, resulting in continuous seaweed and shellfish It is possible to show the effect of improving the whitening phenomenon of

At this time, the starch is made of one or more selected from the group consisting of corn, potato, sweet potato, tapioca and wheat, and the oil and fat is a group consisting of palm oil, soybean oil, olive oil, corn oil, grapeseed oil, coconut oil, butter, lard and fish oil. It is preferably made of one selected from.

If the thickness of the coating layer is less than 0.5 mm, the above effect is insignificant, and if the thickness of the coating layer exceeds 2 mm, the nutrient deficiencies in seaweed farming using fish sauce waste is released This is undesirable because it is too slow.

Hereinafter, the method for preparing a composition for improving chlorosis in aquaculture and nutritional deficiencies in aquaculture farming using fish sauce waste according to the present invention and the physical properties of the composition for ameliorating chlorosis in aquaculture and nutrient deficiencies in aquaculture culture produced by the manufacturing method are described in Examples listen to explain.

In addition, the dissolution rate of dissolved inorganic nitrogen contained in the compositions for improving chlorosis and malnutrition in aquaculture cultured in seaweed prepared in Example 1 and Comparative Example 1 was measured and shown in Table 2 below.

{However, the dissolution rate of dissolved inorganic nitrogen was tested in seawater at 25℃ under no/flow conditions (0, 5, 10 cm/s), and samples were taken on the 5th and 15th days.

A sample net was prepared by weighing 1 g of each composition for improving chlorosis and malnutrition in aquaculture farming, individually wrapped in an onion net, and finishing with a stapler and paper tape. While continuing the test under the same conditions for 30 days, a sample net was taken out and sampled one at a time to measure the dissolution rate. 3 replicates per composition were run. A dissolution test was conducted for each flow rate (0, 5, 10 cm/s) conditions using a circulation device capable of adjusting temperature and flow rate. In the case of non-flow conditions, the experiment was conducted in an incubator. Seawater was collected and used from the Saemangeum seawall in Gunsan-si, Jeollabuk-do or the National Seaweed Research Center in Haenam-gun, Jeollanam-do.

During the flow rate condition experiment, the onion net sample was put into a pipe-type water tank made of acrylic, and the dissolution test was conducted under the desired experimental conditions until the reference date of dissolution by circulating seawater with a circulator that can control the temperature and flow rate. In addition, the sample was prepared by removing the sample net from the water bath, pulverizing the sample with a pestle, dissolving it in water, and adjusting the volume to 100 mL in a volumetric flask. The prepared samples were analyzed for nitrogen content by Kjeldahl analysis.
