摘要：

The aim of the study was to investigate the feasibility of nutrient recycling from a marine recirculating aquaculture system (RAS) for fish (European sea bass, Dicentrarchus labrax L.) through three salt-tolerant, halophyte plant species, Tripolium pannonicum (Jacq.) Dobrocz., Plantago coronopus L., and Salicornia dolichostachya (Moss.). Halophytes, illuminated by sunlight and supplemented with artificial light, were maintained in hydroponic cultures integrated in a RAS water treatment system operating at 16 psu salinity. During a 35-day experiment, 248 fishes gained 5.6 kg of weight. Total plant biomass production reached 23 kg in 14 m(2) hydroponic culture area. Gain of shoot biomass was 27, 18, and 60 g m(-2) day(-1) for T. pannonicum, P. coronopus, and S. dolichostachya, respectively. The plants retained 7 g phosphorus and 46 g nitrogen under the experimental conditions. This was equivalent to 9 % of the N and 10 % of the P introduced with the fish feed. The edible part of the harvested plant material was microbially safe and approved for human consumption. The coupling of production in a RAS-IMTA was tested as a feasible cascading production technology for sustainable aquaculture.
