Law of Sturgeon Caviar protection are neither a full-fledged national Law nor a purely legal matter. These Law are tied to Research and Scientific Data proposed by fisheries and environmental scientists, and are built on three pillars, each of which alone is not enough to rely on. On the other hand, International Perspectives on Conventional Law are another factor in expanding the protection of these valuable animals. Thus, with the nationalization of fisheries in our country on the one hand, and the growth of expectations from this sea to alleviate poverty and expanding the trade and oil and gas exploitation industries and in general, increase of the power and ability to capture and have possession on the nature of this sea and borderless pollution on the other hand, national research and international efforts were made to preserve and survive these valuable animals. Also, the Iranian legislature saw itself in a situation where it had to take a more serious step in cutting off the hidden and visible categories by economically considering the crime of smuggling of the sturgeon aquatic animals. The result of this research is that although it is now an Economic and Smuggling crime the illegal catch these fish, but the national and international law faces this crime and trade, especially the requirements of international institutions such as International Union for Conservation of Nature (IUCN) and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is not efficient and effective, regardless of the data of fisheries scientists and environmentalists in any region. The decision of the Supreme Court as an excellent reaction of local authorities that has been issued regarding about the types of mild and severe violations of the law is important here, given the international requirements. It can be said that the political will of Iranian legislators and decision makers to some extent is consistent to these national, international dimensions, fisheries scientific data from the point of view of species protection and environmental protection of natural habitat and fight against pollution and finally economic attitude to fishing. And the black trade of these fish has received good attention, all of which show that supporting these fish requires a comprehensive legal, judicial, national, international, and scientific policy.
