Abstract
Aquaponic is a combination of fish and plant cultivated in recirculating systems. Fish culture in closed recirculating systems causes organic waste accumulation in the system. If these metabolites are used for plant nutrition, they are not mere waste, but have economical value and however benefit the fish production systems. Most aquaponic systems are designed as perlite-filled media, thin layer of nutrient solution, or Raft system. Photosynthesis parameters and water relations are good indexes for recognition of healthy plants and are used as tools for studying physiological conditions of plants. In this experiment, mint plants were cultivated in Raft aquaponic system and perlite medium. In Raft system, plant roots were suspending in water and absorbed water from pot bottom. Whereas in perlite system, roots were in the perlite medium and irrigation water was applied from top of the pots. The plants grown in Raft system showed mineral elements’ deficiency as leaf chlorosis. Photosynthesis and water parameters analysis showed that photosynthesis rate, stomatal conductance, transpiration, mezophyll efficiency, water use efficiency and photosynthesis active radiation were higher in the plants grown in perlite than in raft aquaponic system. On the other hand, stomatal conductance, leaf temperature and sub-stomatal CO2 were higher in the raft aquaponic system than perlite medium. Thus, due to better physiological conditions of mint plants, perlite medium might yield better results compared to raft aquaponic system.
Investigation of the growth and development, essential oil and minerals content in two species of mint in hydroponics and aquaponics

Abstract
Abstract Aquaponic is the combined culture of fish and plants. This experiment was arranged as a factorial in the framework of completely randomized design with two factors of growing system (aquaponics and hydroponics) and plant species (Mentha piperita and Mentha sativa) with 3 replications. The results showed that most growth factors of the two species were higher in hydroponics compared to aquaponics. Aerial parts and root fresh and dry mass, leaf area and number of nodes were higher in hydroponics compared to aquaponic culture. SPAD index was influenced by the culture system and its value was higher in hydroponic system. Essential oil content of M. sativa was higher in hydroponics and of Mentha piperita was higher in aquaponics. Lower amount of Mn and Mg in Mentha sativa shoots and N, P, Mg and Mn in Mentha piperita was the probable reason for growth reduction of plants in aquaponics as compared to hydroponics.

Abstract
The present study was conducted with the aim of symbiotic integration of Cyprinus carpio and five species of mint in the aquaponics system. The experiment was performed as a split plot design in time. Mentha species including Mentha aquatica, Mentha pulegium, Mentha spicata, Mentha suaveolens and Mentha piperita were considered as the main plot and harvest times (first and second) were used as sub-plots. The highest leaf number, internode length, number of stolon and leaf area were belonged to M. aquatica. On the other hand, M. aquatica, M. piperita and M. pulegium showed the highest shoot dry weight and stem diameter, while, the highest dry weight of stem and plant height were obtained in M. pulegium. The highest leaf/stem ratio was also observed for M. suaveolens, M. spicata and M. aquatic, respectively The highest relative water content (RWC) was related to M. piperita, which was not significantly different from those of M. aquatica, M. spicata and M. suaveolens. The highest greenness (SPAD) index was obtained in M. aquatica and M. piperita. Almost all of the studied traits including leaf fresh weight, stolon fresh weight, shoot fresh weight, leaf number, plant height, number of stem, leaf area, RWC and SPAD index were higher in the second harvest of mint species. Overall, M. aquatica and M. piperita showed a better performance than other species in terms of most of the studied traits and may be recommended for cultivation in the aquaponics system.
