“…Magnesium was within the range of 1-6 mg L -1 , while in Martins et al (2009) it was 7.5-21 mg L -1 . Seawright et al (1998) found that apparent f ish retention of Mg 2+ was 19-22% of Mg 2+ in the diet, but presence in solids was fairly high (i.e., 14-24%), so they conclude that while the biological availability of Mg 2+ in the diet is high, it is less than that of K + .…”

“…Increasing fish biomass also implies increasing the total amount of feed provided per tank, which tends to increase the concentration of dissolved anions and cations involved in the nitrogen and carbon cycles (Seawright et al, 1998) as well as dissolved minerals, such as K + , Mg 2+ , Na + , P and S (Martins et al, 2009). Theoretically, doubling the fish biomass should double ion production, but few studies have considered how ion production varies over time in relation to different fish densities or feeding levels.…”

Aquaponics is the science of integrating intensive fish aquaculture with plant production in recirculating water systems. Although ion waste production by f ish cannot satisfy all plant requirements, less is known about the relationship between total feed provided for f ish and the production of milliequivalents (mEq) of different macronutrients for plants, especially for nutrient flow hydroponics used for strawberry production in Spain. That knowledge is essential to consider the amount of macronutrients available in aquaculture systems so that farmers can estimate how much nutrient needs to be supplemented in the waste water from fish, to produce viable plant growth. In the present experiment, tilapia (Oreochromis niloticus L.) were grown in a small-scale recirculating system at two different densities while growth and feed consumption were noted every week for five weeks. At the same time points, water samples were taken to measure pH, EC 25 , suggesting that it would be rather easy to maintain small populations of fish to reduce the cost of hydroponic solution supplementation for strawberries.Additional key words: aquaculture; nutrients; recirculating system; tilapia; water quality. ResumenAquaponica: integrando la tasa de alimentación de peces y la producción de iones residuales para la hidroponía de fresas La aquaponía es la ciencia de integrar la acuicultura intensiva con la producción de plantas en sistemas con agua en recirculación. A pesar de que se ha encontrado que la producción de iones residuales de los peces no llega a satisfacer todos lo requisitos de las plantas, se sabe menos sobre la relación entre el pienso total dispensado para los peces y la producción en milliequivalentes (mEq) de los diferentes macronutrientes para plantas, especialmente para hidroponía recirculante usada para la producción de fresas en España. Es esencial tener este conocimiento para calcular la cantidad de macronutrients disponibles en sistemas de acuicultura para que los agricultores puedan estimar la cantidad de nutrientes que hay añadir al agua residual de los peces, para un crecimiento viable de plantas. En este experimento, se alimentó a tilapia (Oreochromis niloticus L.) en un sistema de recirculación a pequeña escala a dos densidades diferentes, controlando el crecimiento de los peces y el pienso consumido una vez cada semana durante cinco semanas. A la vez, se tomó muestras de agua para medir el pH, CE 25 2-. La cantidad total de pienso requerido por mEq varió entre 1 y 13 kg, lo cual sugiere que sería relativamente sencillo mantener poblaciones pequeñas de peces para reducir el coste de la solución fertilizante para las fresas.

“…In another study, sea bass Dicentrarchus labrax had a significantly higher muscle concentration of As, Cr, Co, Cu, Mn, Ni, and Ti in fish reared in RAS compared with fish from a flow-through system (Deviller et al 2005). An additional RAS study (Martins et al 2009) also reported higher concentrations of As, Cu, Mn, Ni, and Zn in RAS water with a low water exchange rate (30 l kg -1 feed d -1…”

“…Therefore, dissolved substances such as heavy metals, which are not removed by water treatments in RAS, will accumulate in the water of the system to such levels that they can be toxic to the fish (Deviller et al 2005). Growth retardation, embryonic and larval development impairment and other sub-lethal effects have been observed in many fish species cultured in RAS with low water exchange rates (Davidson et al 2009, Martins et al 2009). Furthermore, there is a possibility of metal accumulations in the edible tissues of cultured fish (Martins et al 2011).…”

There is a growing trend towards culturing fish in intensive recirculating aquaculture systems, which have a reduced need for water exchange compared to many other systems. However, it is unknown whether these intensive aquaculture operations facilitate bioaccumulation of trace elements in fish tissue. The present study therefore evaluated and compared the accumulation of 20 trace elements in the flesh of marbled eel Anguilla marmorata reared in 3 different systems: a recirculating aquaculture system (RAS), a biofloc technology system (BFT), and a concrete pond (CP; traditional method). In the BFT system fish were also raised in polyculture with tilapia Oreochromis niloticus and water spinach Ipomoea aquatica Forsk. Fish were fed the same feed and reared in water from the same source. The trace elements (Al, As, Ba, Be, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sb, Se, Sn, Sr, Ti, V, and Zn) in the fish flesh were analyzed by inductively coupled plasma-optical emission spectrometry. Fish reared in the RAS had elevated concentrations of only a single element (Al) compared with CP fish. This element was also elevated in BFT fish and was probably related to the high Al concentration in the fish feed. Fish reared in the BFT system also showed significantly higher levels of As, Ba, Cr, Fe, Mn, Ni, Se, Sn, Sr, Ti, and Zn compared to both CP and RAS fish. The observed levels of (1) As in fish from BFT systems and (2) Pb in fish from both RAS and BFT systems exceeded national and international legislatory limits. Our results suggest that regular monitoring of trace element concentrations in BFT and RAS should be implemented in the future for this species.

“…In RAS, the pollution is eliminated by biological treatment combined with conventional separation techniques such as sedimentation, fl occulation and fi ltration (Schneider et al 2007, Martins et al 2009, Martins et al 2010, Van Rijn 2013. The membrane fi ltration can be used for improving treatment systems for RAS.…”

Abstract:The aim of the study was to analyze and assess the possibility of using a two-stage fi ltration system with ceramic membranes: a 3-tube module with 1.0 kDa cut-off (1 st stage) and a one-tube module with 0.45 kDa cut-off (2 nd stage) for treating effl uent water from a juvenile African catfi sh aquaculture. The study revealed that during the 1 st fi ltration stage of the effl uent water, the highest degrees of retention were obtained with respect to: suspended solids SS (rejection coeffi cient R I =100%), turbidity (R I =99.40%), total iron (R I =89.20%), BOD 5 (R I =76.0%), nitrite nitrogen (R I =62.30%), and COD Cr (R I =41.74%). The 2 nd fi ltration stage resulted in a lower reduction degree of the tested indicators in comparison to the 1 st fi ltration stage. At the 2 nd stage, the highest values of the rejection coeffi cient were noted in for the total iron content (R IV =100%), COD Cr (R IV =59.52%; R V =64.28%, R VI =63.49%) and turbidity (R IV and R V = 45.0%, R VI =50.0%). The obtained results indicate that ceramic membranes (with 1.0 and 0.45 kDa cut-offs) may be used in recirculation aquaculture systems as one of the stages of effl uent water treatment.
