"Industrial Application Field" The present invention relates to a fish and shellfish feeding stimulant and feed that increase the feed intake of fish and shellfish and promote their growth. ``Prior art'' Since the establishment of the global 200 nautical mile fishing rights, our country, which has benefited greatly from fisheries resources, has been forced to operate within 200 nautical miles of other countries, and naturally the fishery resources obtained there are Costs are increasing year by year due to regulations on fishing season, catch amount, and payment of fishing fees. In view of this fact, the catch of inshore surface fish and farmed fish is increasing year by year. For this reason, large amounts of raw bait and fishmeal used for nearshore surface fish and farmed fish are administered, and the uneaten bait settles on the ocean floor, which is a source of contamination on the continent and needs countermeasures. Furthermore, a decrease in the effective utilization rate of feed leads to a decrease in the growth rate of farmed fish, leading to an increase in costs. For this reason, in the current aquaculture industry, which uses fishmeal and live feed from pelagic and inshore fish, improvements in feed composition to increase so-called feed efficiency, in which normal or higher growth can be achieved with less feed, and live feed are needed. It is desired to develop an alternative feed that maintains the same feed efficiency as compound feeds using fishmeal, etc. As part of such research, there have been reports on feeding stimulants that stimulate fish's sense of smell and taste to induce them to eat food. Glutamine is known as a representative example, but at present, no significant effects can be obtained with so-called mixed feeds that are mixed with feed. Therefore, the present inventors measured the effect of stimulating fish feeding on various substances, and as a result, found that some substances showed excellent feeding stimulating effects, and have already applied for a patent (Patent Application (See No. 61-291889, Japanese Patent Application No. 62-23210). Among these substances, β-dimethylpropiotetin and/or its salt shown by the following structural formula has the most excellent feeding stimulation effect, and therefore, intensive research has been continued with the aim of putting it to practical use. (wherein, The problem was that the cost was high. In addition, β-dimethylpropiotetin has poor chemical structure stability, so it is
Another problem was that it easily decomposed due to the effects of light, the type of solvent, and highly reactive compounds, and its effects were short-lived. Therefore, the object of the present invention is to provide fish and shellfish that have a feeding stimulation effect equivalent to that of β-dimethylpropiotethin, can be produced at a lower cost than β-dimethylpropiotethin, and have excellent long-lasting effects. The object of the present invention is to provide feeding stimulants and feeds of the same type. "Means for Solving the Problems" The feeding stimulant for fish and shellfish according to the present invention is characterized by comprising carboxymethyldimethylsulfonium and/or a salt thereof represented by the following structural formula. (In the formula, X represents a monovalent anion.) Furthermore, the seafood feed according to the present invention contains 10 -9 to 1M of carboxymethyldimethylsulfonium and/or its salt represented by the above structural formula. It is characterized by being kneaded with a solution of "Effect" As is clear from the description of the examples described later, the carboxymethyldimethylsulfonium and/or its salt has a feeding stimulation effect that is almost equivalent to that of β-dimethylpropiotetin and/or its salt. It turns out that it has. Further, the carboxymethyldimethylsulfonium and/or its salt can be synthesized, for example, by the reaction formula shown in (1) below, taking carboxymethyldimethylsulfonium bromide as an example. On the other hand, β-dimethylpropiotetin (carboxymethyldimethylsulfonium bromide) can be synthesized, for example, by the reaction formula shown in (2) below. The reaction of formula (1) above proceeds more easily than the reaction of formula (2) above, and the product is stable, so when synthesized, (1) has a higher yield of the product. gets better. Therefore, the manufacturing cost of the carboxymethyldimethylsulfonium and/or its salt of the present invention is lower than that of β-propiotetin and/or its salt. Furthermore, the product of formula (1) (carboxymethyldimethylsulfonium and/or its salt) is better than the product of formula (2) (β-propiotetin and/or its salt).
(or its salts), it is less susceptible to decomposition due to various external stimuli such as temperature, pH, pressure, light, type of solvent, and highly reactive compounds. Therefore, the effect is excellent in sustainability. In the above structural formula showing carboxymethyldimethylsulfonium and/or its salt, the monovalent anion X is, for example, OH - , Br - ,
Examples include Cl - . The feeding stimulant of the present invention has the effect of increasing the intake of fish and shellfish and promoting their growth when added to various feeds such as synthetic feeds, semi-natural feeds, and completely natural feeds. This effect is observed in all kinds of seafood, including freshwater fish such as carp, crucian carp, goldfish, eel, rainbow trout, and tilapia, saltwater fish such as yellowtail, sea bream, spiny lobster, and flounder, and various shellfish. The feed of the present invention is characterized by the addition of the above-mentioned feeding stimulant, and base feeds include synthetic feeds, semi-natural feeds, completely natural feeds, etc.
Either can be adopted. The method of adding the feeding stimulant is not particularly limited, but it is preferable, for example, to mix the base feed with a solution containing 10 -9 to 1M of the feeding stimulant. In this case, the concentration of the feeding stimulant in solution is
If it is less than 10 -9 M, a sufficient feeding stimulation effect on fish cannot be obtained, and if it exceeds 1 M, an odor is generated and the effect tends to be reduced. "Embodiments of the Invention" (1) Experimental Method and Apparatus FIG. 1 shows the apparatus used in the experiment on the feeding stimulation effect. In the figure, 1 is a water tank, which is supported on a stand 2. A fish 3 is placed in an aquarium 1. A support 4 is erected on the side of the water tank 1, and an arm 6 connected to a recording needle 5.
is rotatably supported by the support column 4 via a support shaft 7. A thread 8 is connected to the rear end of the recording needle 5.
A magnet 9 is fixed to the lower end of the thread 8, and when this magnet 9 comes into close contact with the bottom of the aquarium 1,
The thread is stretched. Experimental bait 10 is attached to the part of the string 8 that is immersed in the water of the aquarium 1. On the other hand, a recorder main body 11 is installed on the side of the water tank 1, and an inverted L-shaped support 12 is erected on the recorder main body 11. Post 12
A rotating drum 13 is provided between the recorder body 11 and the recorder main body 11.
is rotatably supported, and the tip of the recording needle 5 mentioned above is in sliding contact with this rotating drum 13. The rotating drum 13 is driven by a drive mechanism (not shown) provided inside the recorder main body 11, and the rotating drum 13 is rotated for 2 minutes.
It is designed to rotate once every second. To explain the experimental method using the above device,
First, an experimental bait 10 containing various feeding stimulants is prepared, the bait 10 is attached to a thread 8, and the bait 10 is submerged at an intermediate height in the water of the aquarium 1. Then, the rotary drum 13 is rotated to record the pecked state of the bait 10 by the fish 3. That is, when the fish 3 pecks the bait 10, the string 8 held by the magnet 9 is pulled, the recording needle 5 swings, and a record is made on the rotating drum 13. In this way, the number of times the fish 3 pecked the bait 10 was measured while the rotating drum 13 rotated once. In addition, at the same time as replacing the test water for each test, the thread 8, the fish 3, and the aquarium 1 were thoroughly washed with breeding water. (2) Preparation of bait The bait for the test was prepared as follows. That is, cellulose powder was used as the base feed. On the other hand, substances to be tested for feeding stimulation effects
An aqueous solution containing 10 -3 M was prepared. and,
A bait was prepared by taking 0.5 g of the above base bait, adding 0.8 ml of the above test solution, and kneading the mixture in a mortar. The test consisted of mixing the base feed using only water with no added feeding stimulants (control).
(comparative example) in which the base feed was mixed with an aqueous solution containing carboxymethyldimethylsulfonium bromide (β-dimethylpropiotetin) as a feeding stimulant; The test was conducted on three types of baits (Example) in which the base bait was mixed with an aqueous solution in which onium bromide was dissolved. Each experiment was repeated five times, and the total number of pecks was evaluated. Controls were conducted both at the beginning and end of the experiment to observe the condition of the fish over time. The results are shown in the table below.
