“…However, ten studies documenting wetland performance at scales relevant to commercial aquaculture were identified in this review. These studies included surface flow, subsurface flow, and hybrid systems applied to treat effluents from saline mariculture systems (Shpigel et al, 2013), brackish effluents from recirculating shrimp production systems (Lin et al, 2005(Lin et al, , 2010Tilley et al, 2002), and recirculating freshwater ponds or tanks for tilapia and trout production (Buric et al, 2015;Konnerup et al, 2011;Schwartz and Boyd, 1995;Zachritz et al, 2008;Zhang et al, 2010). Table 4 summarizes the data from these studies; details are provided in the supplemental material.…”

Abstract. Excess nutrients from agricultural settings contribute to surface water and groundwater impairment. Constructed wetlands have been widely used for water quality protection in various agricultural systems. We used a synthesis approach to document the performance of constructed wetlands for nutrient removal from a range of landscapes and geographic regions with the following objectives: (1) review the current use of constructed wetlands in agricultural applications, (2) summarize the nutrient removal efficiency of constructed wetlands, and (3) identify the geographic usage and costs associated with constructed wetlands. We reviewed over 130 publications and reports to characterize nutrient removal performance for the following types of agricultural effluents: cropland surface and subsurface drainage, and wastewater from livestock production, greenhouse, aquaculture, and hydroponic systems. Data from the reviewed studies indicate that constructed wetlands are efficient in protecting water quality in agricultural production settings. However, differences in constructed wetland characteristics reported by the studies suggest that standards are needed to ensure nutrient removal goals are met based on wetland design. Researchers should consider including basic performance parameters for constructed wetlands in published reports, including influent and effluent concentrations, hydraulic retention time, hydraulic loading rate, watershed to treatment wetland ratios, and plant species and relative cover. Future studies are needed to explore cost-benefit analyses to assess the feasibility and potential promotion of wetland incentive programs in various geographic regions and watershed nonpoint-source pollution goals for using these systems in agricultural settings.

“…Recent developments in aquaculture are exemplified by the use of intensive recirculating aquaculture systems (RASs) which provide solutions to limitations of water resources and management of effluentsi.e. to provide economic and environmental sustainability (Martins et al, 2010;National Intelligence Council, 2012;Buřič et al, 2015). On the other hand, considerable effort is spent on implementation of intensive culture for new species in RAS.…”

Pikeperch (Sander lucioperca) is commercially important as well as a valued culinary fish with potential for intensive culture. One of the basic problems in pikeperch culture in recirculating aquaculture systems is adapting early life stages to pelleted feed (PF). Our work compares four different ways of adapting 6-week-old pikeperch fingerlings (standard length, SL = 29.30 ± 2.14 mm; weight, W = 0.38 ± 0.08 g) to feeding on a commercial diet. The methods are designated, Ause of trainer fish (Vimba vimba; SL = 36.88 ± 3.28 mm; W = 0.77 ± 0.26 g) and direct application of PF; Buse of trainer fish and gradual addition of PF with natural food (natural feed (NF), chironomid larvae); Cdirect application of PF only; Dgradual addition of PF with NF. The growth trial experiment (including adaptation to PF) lasted 14 days by which time all experimental groups were accepting PF. Pikeperch fingerlings in group A grew significantly faster and PF was more readily accepted compared to other groups (SL = 46.11 ± 4.09 mm; W = 1.44 ± 0.38 g; specific growth rate = 9.48 ± 0.83% day À1 ). Other characteristics observed (total weight increment, feed conversion ratio) also support the use of trainer fish and direct application of PF for pikeperch in their adaptation to intensive culture. It is also an illustration of applicable use of learning potential in fish which can be usable for other fish species.

“…For instance, constructed wetland was proved to decrease and stabilize nitrite levels in recirculating hatchery (Burič et al . ). Denitrifying reactor may be also included in the recirculating system as it is supposed not only to remove nitrite and nitrate but also to raise alkalinity which is being lost during intensive nitrification resulting in pH decline in culture water (van Rijn et al .…”

High nitrite concentrations may occur mainly in recirculating aquaculture systems, but can also be found under certain conditions in natural waters. Among studied freshwater organisms, molluscs and worms followed by fish are the most resistant to nitrite. On the other hand, crustaceans and aquatic insects followed by amphibians are the most sensitive. Wide interspecific differences in nitrite susceptibility can be found within freshwater insects, crustaceans and amphibians. Chloride concentration in water is supposed to be the most important factor influencing nitrite toxicity. Generally, a positive chloride effect on nitrite toxicity reduction can be expected in all aquatic animals (or their early stages) employing gills for breathing and ion exchange. This phenomenon has already been observed in an amphipod (Eulimnogammarus toletanus, Pinkster & Stock), a planarian (Polycelis felina, Dalyell), two species of crayfish, several fish species and in amphibians in early development stages. A relatively huge amount of data on nitrite effects is available for fish, but other freshwater organisms were less frequently studied. Information on chronic effect of nitrite is nearly completely missing.
