In the present work, the feasibility of utilizing R404a as refrigerant along with nano particles (Al2O3, CuO and TiO2) as additives in nano particle eco friendly chilling plant for fish processing. The performance analysis used three different nano particles each with five combinations for the assessment for R404a. The best performance of the system was identified using the comparison of system parameters like COP, compressor work input, refrigerating effect, compressor suction and discharge pressure and temperature at all the state points of the system. COP analysis of R404a with nano particle of Al2O, CuO and TiO2. Since the emphasis has been laid on COP and evaporating temperature not given primary importance and hence the study concludes that the mixture of R404a offering the COP of 3.97 with 3% CuO having 29.6 kj/kg-K work input to the compressor along with highest refrigerating effect of 119.40 kj/kg-K can be used as an alternative refrigerant for nano particle eco friendly chilling plant for fish processing at the temperature range of -11°C. The performance characteristics of the system may provide a guideline for the cold chain application in fisheries and its allied applications.Keywords

In a recirculating aquaculture system (RAS), waste is generated from uneaten feed, fish faecal matter and organic debris from dead and dying organisms. These wastes generally decompose to produce mainly nitrogenous compounds in the form of ammonia, nitrite and nitrate. These nitrogenous compounds are particularly important in intensive RAS because of their toxicity to culture organisms. Therefore, removal of these compounds is very much necessary for successful operation of RAS. Adsorption, ion exchange and biological filtration are the three major available options for removal of nitrogenous wastes. In the first two options, frequent regeneration of media is required which usually increases the cost of the operation. Therefore, in the present study biological filtration has been chosen an option for aquaculture wastewater treatment. In the present study proper sizing of biofilter based on mass balance approach has been presented which is of critical importance to the successful design of any recirculation system.Keywords

This paper deals with the development and performance evaluation of aquaponics system. In the present study GIFT tilapia fingerlings and foxtail amaranth (Amaranthus gangeticus) seeds were procured and grown in fish culture tank and plant bed, respectively in aquaponics unit. This study demonstrates and evaluated the growth of GIFT tilapia and foxtail amaranth (Amaranthus gangeticus) grown in aquaponics system and normal culture system. The fish fingerlings of average weight 0.70 g were procured from a fish farmer. The fish weight was recorded in aquaponics and glass tank and was found to be 83.20 and 78.10 g, respectively after 160 days of culture. Plant height observed in aquaponics system and normal culture system which was recorded as 18.10 cm and 20.20 cm, respectively. The recirculation flow rate in aquaponics was maintained 0.43 L/throughout the culture and the average biofiltration efficacy was found to 23 per cent. Fish were fed at the rate of 12 per cent of body weight with commercially available feed.Keywords
