The proliferation and cultivation of ornamental fish with an economic and decorative approach is one of the important activities of the aquaculture industry, which has grown over the recent decades and occupies a significant part of international trade. In addition to this growth and development, one of the most important challenges facing the industry is the emergence and occurrence of various diseases, including the involvement of protozoan parasites, which cause many problems in these fish, including growth retardation, delayed sexual maturation or fish infertility, casualties, high cost of treatment and control of parasites. Also, parasites often provide the basis for other diseases, such as Bacterial, Viral and Fungal infections, which cause severe mortality and morbidity. Therefore, this study reviewed the types of pathogens of ornamental fish and presented solutions for their control and treatment.

This research was conducted to investigate the production process of goldfish and sexual maturity of oocytes at the time handling of breed. In the mosquito breeding complex, Dr. Yusefpour was take. For this purpose, 250 nambber female mature with middhe weiths 23.74g . Monthly, 50 female breed from tank selected randomly and after weighingand measure the length, gonad and liver weith, liver and gonadotropic index were determined. Each month, three ovarian tissue samples were prepared and, after the dehydration and clarification stages, the coloring was crried out on samples. Of each sample ovary was prepared the three areas, front, center and behind. The resulths showed that in the early months of sexual (December), a percentage of oocytes stage One and Two in compared to the oocytes of Three and Four than (April). In all months in each Three area front, center and behind oocytes were seen in stages three and four. The frequency of oocytes in stagevfour increased with increasing of sexually stage (April), increased in the ovary front.

In this study, the effects of selenium nanoparticles on sperm quality and reproductive performance of fish were investigated. Today, given the growing world population, providing healthy and adequate food is one of the critical issues in many countries in the world, especially in developing countries. Aquatic animals can play a vital role in providing the nutrients needed by the community. Fish reproduction control is a key issue in aquaculture. Fish quality is one of the factors limiting the reproductive success. In addition, the quality of gamet fish can be very variable and affected by a large number of external factors. The presence of minerals in the diet is essential, even minor changes in levels of these substances have significant effects on reproductive health and reproductive performance. Selenium is a negligible mineral that, as a component of enzymes such as glutathione peroxidases, as well as selenoproteins, plays an important role in various biological processes including antioxidant defense, male and female fertility, thyroid metabolism, immune function, endotracheal function, and muscle development and function Also acts as a catalytic center in the active site of the antioxidant enzyme glutathione peroxidase. Fish, and in particular free fish, may have relatively high levels of antioxidant properties in selenium to protect themselves from high levels of highly unsaturated fatty acids (PUFAs) that are susceptible to peroxidation. Selenium and selenoproteins, therefore, guarantee the survival of spermatozoa and protect against reactive oxygen species (ROS), and reproductive performance may also be increased through selenium.

Due to the stature and the beauty of sturgeons, tendency to keep them in the aquarium has increased. There are 27 species of sturgeon in the world that have inhabited the lakes and rivers of the northern hemisphere. There are 6 sturgeon species in the Caspian Sea. Amongest the sturgeons of the Caspian Sea and its catchment area, Sterlet (Acipenser ruthenus) and Stellate sturgeon (Acipenser stellatus) are more suitable for keeping in the aquarium than other species of sturgeon. But Sterlet is more important for keeping in the aquarium. Ofcource, it is possible to keep other sturgeon species in the aquarium. However, due to their higher growth rate, they were more difficult to maintain in the long time and needed aquariums with more water volume and dimensions. To maintain sturgeon in an aquarium, the length and width of the aquarium should be large enough so that the fish can swim freely and swing easily. This means that, the length of the aquarium should be, at least 6 times the length of the fish and its width at least 2 times the length of the fish. Water depths are less important, but more water volume, provide more sustainable encvironmental condition. Sturgeons feeds throughout the year, but the amount of food consumed is lower in the winter. Their food is comparable to other carnivorous fish. In general, from the aspect of existence specific, sturgeon fish are intermediate salmonids and cyprinids.
