Q67 Is it safe if it is fish and shellfishes? A Compared with a flesh-of-animals product, fish meat has the image which seems to be healthy. But, it is not applied to a farmed fish at all. The subsequent contents have main subject of Japan. The ill repute of a yellowtail is roaring truly. But, other farmed fishes are as practically equal as a yellowtail in toxicity. Recently, safety set aside and only the cultivating method progressed. A fish which is not supposed before is a culture thing. Since a fish dealer is also trade first, unless it is a very conscience-store, the true character of a farmed fish is not revealed. There are some troupes who sell a culture yellowtail cooly and are not ashamed of it as a natural yellowtail. Such a dangerous fish rides on a circulation base, and is sold openly. The Japanese government's food administration is very inferior. In order that they may take care of some of culture contractors, does he plan to massacre the whole Japanese? A yellowtail is bred overcrowded in a narrow live-box. Synthetic feed is also mixed although, as for food, a sardine etc. is given. The person who had tropical fish and the goldfish bred will know. Various medicines are sold to sick prevention and medical treatment of a fish. The same thing as it is struck and crowded in a fish preserve in large quantities. Since a fish tends to weaken by overcrowded breeding, it is necessary to prescribe a medicine for the patient in large quantities. Since a fish preserve is mixed with sea water, the remaining dregs of food, the medicine prescribed for the patient, the filth of a yellowtail, etc. pollute surrounding sea water. Sludge has accumulated on the seabed of the ocean space which was carrying out overcrowded breeding of the yellowtail long thickly. In such an environment, since it becomes easy to generate an oxygen shortage and an infectious disease, a further high-concentration medicine is poured all over the sea. The net is spread around by the live-box. But, if a fish hits a net, it will get damaged and will not become a sale thing. From a basis, since about they are in an immunity insufficient state, they will die immediately. Then, a contractor plasters an antibacterial medicine specified to be a net by the powerful drug. This antibacterial medicine is known for toxicity being strong. But, it goes into the inside of the body from a wound, and the portion of meat is polluted. The hormone drug is also prescribed for the patient in large quantities with the natural matter. Furthermore, since the yellowtail is cultivated in the adjacent seas near a city, it also takes in the pollution ingredient of adjacent seas inside of the body as it is. The ingredient is different by what factory is situated in near. The identity of a yellowtail is found by investigating a pollution ingredient. And dioxin is almost certainly contained. And it should remain by high concentration. As already stated, since dioxin is the substance stabilized extremely chemically, it is not decomposed easily. The dioxin which polluted the ground goes round and flows into the sea from river. Plankton takes it in and small fish eats. It is contained also in the small fish of the food of a yellowtail. Of course, dioxin is contained in the sea water of a fish preserve itself. But, it is accumulated in many cases from food. It is tended to absorb dioxin oil and it has the character to be easy to collect on the fat of an animal so that it may be found also by PCB incident. It will be more mostly accumulated to a fatty fish. In addition, cadmium, organic mercury, a radioactive element, etc. are accumulated by this food cycle. Although this is the actual condition of yellowtail culture, probably, you may suppose that culture of an eel is almost the same. As for the cultivating method, the sea bream and the flatfish are also alike. But since the history of culture is not a yellowtail, they have a little low degree of contamination of adjacent seas. As for a few, it is help that they are it and a fatless fish. This site has described the danger of import food. But, about a farmed fish, the way of an import thing is conscience far. That is because it has not bred overcrowded severely rather than Japan. There is little contamination of adjacent seas and it is because a medicine can also be managed with the amount of small. Since food is also cheap, the cost of natural feed can use it for it. Accumulation of the poison by the food cycle is not so awful as Japan, either. In the polluted sea in Japan, overcrowded culture may be that it is not suitable in essence. With the present condition, future is not in fish culture of Japan. If safety is unestablishable, they should abolish immediately according to conscience. As a domestic farmed fish, the eel of Taiwan is comparatively safe outside. The taste is also full of matters with just sufficient being good, fat having also ridden and moreover a price being also cheaper than made in Japan. Eel culture of Taiwan was performed by technical instruction of Japan from the first. But, they have a question in the way of the overmedication, and research was made in quest of the safer fish breeding method. An eel safe as a result can be cultivated now. The sea bream is excellent in the culture thing of Australia. Taking advantage of the blessed environment, it is cultivated in the almost pollution-free state in the large nursery. The taste also has the opinion referred to as rough compared with the natural thing of Setonaikai. But, it may be an extravagant criticism if safety is supposed.
