The experiment was carried out in completely randomize design with four levels 0 (control), 1% (T1), 1.5% (T2) and 2% (T3) that each treatment had 3 replications.  Amount of absolute fecundity in T2 significantly was higher than control (p0.05). Gonadosomatic index in T2 and T3 was upper than control and T1 that this difference was significant (p<0.05). The highest hatching percent was observed in T2 (75±9.28) and T3 (66.95±8.85), respectively, so that significant differences (p0.05). Regarding to findings of this research, addition prebiotic Immunogen at level of 1.5% to angelfish breeders;#39 diet was recommended for reproductive indices promotion.  Prebiotic Immunogen Reproductive performance Angelfish (Pterophyllum scalare). 2015 4 01 1 9 http://ornamentalaquatics.ir/article-1-36-en.pdf

Fish averaging 1.16 ± 0.09 g were randomly stocked into aquarium. Four experimental diets were prepared to contain onion powder at the concentrations of 0, 0.5, 1 and 1.5% respectively. In order to adapt the fish to experimental condition at the end of trial blood indices, WBC, RBC, Hb, and HCT were determined. Haematocrit was significantly (p<0.05) higher in the group fed onion powder 0.5% and 1% compared to the control group. In conclusion, it can be suggested that dietary inclusion of 0.5% onion powder was effective at improving hematological parameters of goldfish.

Up to now, several hybrids of aquatic animals, particularly fishes, that produced naturally or artificially, have been reported. Also there have been several hybridization in reproduction and breeding industry of ornamental fish, that this study introduce them. Scientific documentations about these hybridizations are few, and most of the texts in internet are experiences of ornamental fish enthusiasts. There are disagreements about parental species in most of the hybridization, and various studies maybe consider different parental species for a hybrid, and finally it must be said that more researches about ornamental fish hybridization are required.

Journal of Ornamental Aquatics 3 2423-4575 2423-4575 10.22034 2015 2 1 The effects of nanoparticles on aquatic histopathology S Saed moucheshy Saed8893@gmail.com M Sudagar M Mazandarani S.S Hosseini he use of nano-technology and nano-enabled products in the industry is the widely expanding. The nanoparticles used in aquaculture in order to cure disease and to control the bacterial load of water can be verified. Nanotechnology is the use of nano-scale structures (at least one Bd100-1 nm), respectively. So that the scale has a wide application in science, chemistry, biology and medicine. Today, with the increasing development of nanotechnology much concern about the potential risks of nanoparticles containing materials release to the environment has been created. So that the release of these substances into the aquatic ecosystems can have undesirable effects on their life species. To evaluate the toxicity of environmental pollutants in fish are different physiological parameters such as including histology. According to the research of nanoparticles affect the tissues of the skin, gills and liver, kidney and intestines is. In this study, the effects of nanoparticles on various of fishs tissues are examined.

Sea cucumbers are important due to the rotation of key nutrients and high medicinal values. With this respect and the lack of scientific knowledge about them, this research was done to identify dominant species of sea cucumbers with aim in the intertidal habitats of the Hengam Island, located in the Hormoz Strait (Persian Gulf). The field sampling and survey have been done during the two semesters and carried out along the coastline based on geomorphology and habitat characteristics of 8 selected sampling stations in inter-tidal zone. Samples were collected during one year (from 2011 to 2013) and transferred to laboratory and identification was done by spicules extraction and using some valid identification keys. Species of sea cucumbers were identified were:  Holothuria impatiens, Holothuria leucospilota, Holothuria arnicola, Holothuria parva and Holothuria bacilli. Holothuria leucospilota as the most dominant species distribution and abundance have been introduced.

The past few decades have seen an increased interest in the West in Koi keeping, motivated, at least in part, by the fact that we spend more time in and around the home. As a pastime, Koi keeping combines the nurturing qualities of a pet-lover with the aesthetic pleasure of enhancing ones home and garden. An appreciation for the culture and tradition of the East is also evident in the trend toward keeping quality Koi recognized varieties, and marking an effort to meet their special. Termed living jewels Koi have enchanted their admirers for centuries and their popularity shows no sign of waning.  Koi (Cyprinus rubrofuscus) Common carp Warm Water Aquarium Fish Pond Fish. 2015 4 01 37 41 http://ornamentalaquatics.ir/article-1-41-en.pdf
