Green terror (Andinoacara rivulatus) is one of the most popular ornamental freshwater fish of the Cichlidae, which is very common in our country. The aim of this study was to investigate the cause of green terror losses in an ornamental fish breeding center. In the summer of 1400, following the chronic and continuous losses of mature green terrors in a center for the reproduction and breeding o...
BACKGROUND Antimicrobials are used to directly control bacterial infections in pet (ornamental) fish and are routinely added to the water these fish are shipped in to suppress the growth of potential pathogens during transport. METHODOLOGY/PRINCIPAL FINDINGS To assess the potential effects of this sustained selection pressure, 127 Aeromonas spp. isolated from warm and cold water ornamental fi...
Ornamental fish farming, like other aquaculture productions, it depends on the quality and quantity of egg production, hatching, fecundity and survival of the larvae. In general, every step of aquaculture, followed by nutritional goals. Most of these studies are in the stages of larval growth. Because the highest costs are imposed on aquaculture and the most critical biological period of orname...
Since 1993, various public and private institutions have supported the development of a freshwater ornamental industry in Hawai‘i which, based on current success, must be intensive and utilize the latest in culture technologies to remain competitive. Feeding and palatability trials using commercial feeds suggests that very little is understood about the nutritional requirements of the 1500 spec...

Little is known about the nutrient requirements of most ornamental fish species. In many cultivars of fishes, such as Ornamental fish, especially in those new Ornamental fish species introduced to the aquaculture industry, the rate of fecundity is an i...
Biofloc technology (BFT) is a relatively new biotechnological means to support high density culture, maintain water quality, biosecurity, reduce the need for water exchange, reutilize the feed and reduce the production cost. This technology is mainly based on the principle of waste nutrients recycling (particularly nitrogen) into microbial biomass that can be used in situ by the cultured animal...
