the increasing world demand for fish cannot be met by capture fisheries. aquaculture production is increasing and nowadays cage culture has an important role in meeting the world’s fish demand. the design of the physical structure of a cage is determined by the oceanographic conditions of the culture site. each design is site-specific and knowledge of the topography, wind force and direction, p...

background: malassezia furfur is alipophilic yeast that causes skin disease. objective: to evaluate the level of il-10, ifn-γ and il-12p70 in co-incubation of m. furfur grown on different forms of natural oils with pbmcs of healthy individuals. methods: pbmcs were obtained from blood samples of normal volunteers. m. furfur was cultured in different culture media containing almond oil, fish oil,...

There has been a paradigm shift towards reclamation of wastewater from high cost to low cost effective technology for treatment of sewage and resource utilization for economy driven activities.Under appropriate conditions, sewage fed fisheries would reduce the cost of fish production by utilizing the sewage induced natural plankton and become cost effective because of savings through chemical f...

Ornamental marine species ('OMS') provide valuable income for developing nations in the Indo-Pacific Coral Triangle, from which most of the specimens are exported. OMS culture can help diversify livelihoods in the region, in support of management and conservation efforts to reduce destructive fishing and collection practices that threaten coral reef and seagrass ecosystems. Adoption of OMS cult...

the aim of this study was determination of abundance and biodiversity of zooplankton community at integrated fish culture of grower and fingerling fishes at east of golestan province, gonbade kavous city. sampling was done monthly at 6 ponds during one season culture from june to november 2011. during six month study period, 4 groups and 27 genuses were identified. between recorded groups, 12 g...

A completely randomized experimental design was conducted to estimate ammonia excretion rate by red tilapia (Oreochromis sp.) during different stages of its growth in recirculating water system units typically designed to meet the experiment purposes. Eight weight groups each containing 75individuals of 20, 30, 40, 60, 80, 120, 180 and 200g average weight were considered as treatments in duplic...

resistance of microencapsulated fish oil (mfo) in the rumen and its effects on fermentability of nutrients in the rumen was studied in 3 experiments. the key parameter in these studies was the amount of oil released from the microcapsules and their effects on gas production and rumen degradability in comparison with unprotected fish oil (fo). in the first experiment the effect of rumen and abom...

In opposition to toxicology of mammals piscine toxicology is closely connected with the conditions of external environment. The aquatic environment is necessary for embryonic development and after hatching during short or long-lasting larval period of most fish species. An aquatic environment is polluted by many industrial and agricultural wastes. Ammonia as a toxic and common compound in water...

An economic anylysis was made to determine the cost of fish production in the floodplains at Daudkandi Upazilla in Comilla district during the period form January to April, 2007. Survey method was followed to collect data from 20 floodplain aquaculture projects. The projects record books and personal interviews of the NGOs and Fisheries officers were the main instruments of data collection. Sta...
