[Prior art]
Animal feeds are mainly used as feeds used for marine animals, and raw fish, fish meal, crustacean, willow meal, earthworms, etc. are used alone or in combination of two or more, as they are or in pellet form Etc. are used after being processed. These feeds have basically been used traditionally as foods preferred by marine animals for a long time, and each has their own specific bait / attractive activity. In addition, squid oil that has been used since ancient times and an oily extract of earthworms are known to have an attractive effect. Recently, many studies on amino acids and related substances and nucleic acid-related substances have been made. In addition, it has been reported that attracting effects are recognized in carbohydrates and lipid metabolites. On the other hand, those that have an effect of feeding / attracting or promoting feeding on aquatic animals are mainly those of animal type, and there are a wide variety such as plankton, coelenterate, annelid, mollusc, arthropod, fish, aquatic algae, etc. Examples can be seen. On the other hand, only the lettuce, the plant belonging to the genus Ferla, senkyu, garlic and the like have been known as land plants. Recently, however, 8 kinds of spices, 20 kinds of herbal medicines and 21 kinds of fruits have been found to have a bait activity effect on black abalone, loach, and yellowtail, and their use is expected in combination with their effective action. ing.

[Problems to be solved by the invention]
In reality, in the case of fish feed, in order to improve economic efficiency, the feed efficiency is increased and the growth of aquatic animals is accelerated. At the same time, environmental pollution caused by leftover food is reduced, and the disease rate is gradually reduced. It is necessary to measure, and further improvement of fishing results is desired for fishing baits. Therefore, in any case, foods with higher bait / attractive activity are required first. However, foods that have been used traditionally and those that have an attractive effect are mainly used. They are of animal type, they are difficult to use in practice, or their availability depends on the weather conditions during use, and there are problems in transportation, storage, etc. in terms of qualitative stability, There is also a problem that the contents pollute the environment and cause bacterial contamination. In relation to this problem, it has recently been found that spices have a bait activity effect and are expected to have a bactericidal effect, which is also expected to have medicinal effects, and fruits rich in vitamins and minerals. In the same way, vegetables that are rich in carbohydrates, dietary fiber, vitamins, carotene, and minerals and that have various aromas are also searched for. It is important to measure its use, but there are only a few examples so far.
[0004]
[Means for solving problems]
The present invention has been made to solve the above-mentioned problems, and its purpose is to produce it systematically, qualitatively stable, and rich in carbohydrates, dietary fiber, vitamins, carotene and minerals. The purpose of the present invention is to provide a method for enhancing the food and attracting activity of marine animals using the food and attractant active substances obtained from vegetables having various fragrances. In order to achieve this object, the present invention is characterized in that water or hydrous alcoholic extract of udo, turnip, cabbage, perilla, sengoku, radish, leek or horseradish is used as a food / attractive active substance for aquatic animals. More specifically, the vegetables having bait / attractive activity referred to in the present invention are: Udo is the ground stem of Arria cordadata, turnip is the root of Brassica campestris, and cabbage is Brassica oreracea var. The capitata leaves and perilla are from Perilla fruitessens var. acuta leaves, syringae is the leaves of Chrysanthem coronarium, radish is Raphanus sativas var. Acanthiformis radix, leek is Allium tubarosum leaf blade and bulb, horseradish is Eutrema wasabi) rhizome, water or hydrous alcohol extract is used as is or concentrated, but adjusted to an appropriate pH if necessary In some cases. These are mixed with feed for aquatic animals, or mixed, adsorbed or adsorbed on other suitable carriers, and used for a method for enhancing the aquatic animal feed / attractive activity.
[0005]
[Action]
These bait / attractive active substances based on the methods of preparation and use as described above exhibit remarkable attractive activity for marine animals. Furthermore these 攝餌-attractant composition for aquatic animals comprising been added to Tsuriesa and for fish culture feed is, with攝餌effect in a further fish enhances 攝 food-attractant activity, improvement in economic efficiency required for feed You can expect.

【Example】
[Method]
A test sample of 7.5 ml (pH 6.5) is soaked in a gauze, and this is a predetermined position A, B in the test zone of the attractive test tank shown in FIGS. Place in C and D (Dough: Stand up a cylinder with small holes, Black abalone: Place the rounded gauze at the bottom, Buri: Suspend the rounded gauze). Along with the installation of the test sample, water or seawater at a flow rate of 500 ml / min for loach, 150 ml / min for black abalone, and 1000 ml / min for yellowtail is poured and the septum is immediately raised. The loach and yellowtail are measured for 10 minutes every minute, and the black abalone is measured every 20 minutes for 20 minutes every two minutes. This test is performed four times based on the Latin square method, the number of fish or the number of individuals for each minute is summed and integrated with the passage of time, and the time course of the number of staying cats or the number of individuals is calculated using the logistic curve y = g / When the fitting coefficients g, r, and a were determined for {1 + exp [−r (x−a)]}, the attracting indices for loach, black abalone, and yellowtail were a, a, and gr, respectively. Here, a represents the average residence time (minutes) in the loquat and black abalone test plots, and gr represents the instantaneous number of activity of yellowtails in a (minutes). Further, y represents the number of tails or the number of individuals in x (minutes), and the coefficients g, r, and a are constants. In addition, apparent search and feeding behavior were observed. In addition, the display criteria for the determination of food / attractive effect are defined as shown in Table 1 by comparing the attractive index of the test sample and the apparent search diet behavior with the control (no test sample). Based on the above, the bait / attractive effect was displayed for each example. The results of the above procedures were combined to examine the feeding and attracting effects of each sample.
[0007]
[Example 1]
With regard to loach, black abalone, and yellowtail, the effects of feeding and attracting with the vegetable water extract described in Table 2 were examined. The results are shown in Table 2. This example shows that turnips, cabbage, potatoes, and onions have a positive attractive effect on all marine animals such as loach, black abalone, and yellowtail. Udo, ginger, broad bean, horseradish, mugwort have an attracting effect on loach and black abalone, Japanese radish, carrot, mioga, rakyou have an effect on loach and yellowtail, and green beans, celery, lettuce have an attractive effect on black abalone and yellowtail. It is shown that. In addition, cauliflower, sunny lettuce, garlic, spring bream, leek, parsley, broccoli, and honey bean attracted to loach, red pea, burdock, seri, and bamboo shoot attracted to black abalone, and cucumber and perilla only attracted to yellowtail. It shows that there is.
[0009]
[Example 3]
With regard to loach, black abalone, and yellowtail, the dietary / attractive activity effects of the hydrous alcoholic extracts of vegetables listed in Table 4 were examined. The results are shown in Table 4. Also in this example, as in the case of Examples 1 and 2, the hydrous alcoholic extract of vegetables was all of turnip, ginger, broad bean, wasabi, mugwort, and turnip, ginger, broad bean, wasabi, and mugwort. And radish, radish, carrots, ginger, and rakkyo were found to have an attractive effect on loach and yellowtail, and green beans, celery, and lettuce were found to have an attractive effect on black abalone and yellowtail.
[0010]
【The invention's effect】
As described above, by adding water or hydrous alcoholic extract of Udo, turnip, cabbage, perilla, sengoku, radish, leek or wasabi to the aquatic animal, the bait activity for the aquatic animal is increased.
Improvement in fishing results can be expected by being absorbed or adsorbed on fishing baits or other suitable carriers. For fish farming, the effect of bait is increased, and the growth of aquatic animals is accelerated. Moreover, this bait / attractive active substance is available in a stable manner and has high utility value in that it is qualitatively stable.
