Special Issue Information

Dear Colleagues,

Water is fundamental for all living beings, especially aquatic organisms. However, with the growth of aquaculture production, it will become increasingly necessary to meet the growing demand for healthier food. In this context, and to enable the constant growth of aquaculture production, it is necessary to develop more sustainable and space-efficient production systems that use less water. In this sense, recirculating aquaculture system, aquaponic system, and biofloc technology, among others, are fundamental for more sustainable aquaculture. Furthermore, it is important to evaluate the different management, nutrition, and physiological responses of animals when cultivated in these systems, aiming to maximize water use.

The combined production of three varieties of lettuce (romaine, iceberg, and red leaf) with flathead grey mullet (Mugil cephalus) was tested in triplicate in three independent coupled aquaponic units with no thermal control. For this purpose, a total of 114 fish (2.5 kg/m3) were stocked in each fish tank (2 m3), and 92 lettuces were planted in the hydroponic unit (6 m2). As no thermal control was included in the design of the aquaponic system, water temperatures declined from maximum values of 20.4 °C to minimum values of 5.0 °C, which directly affected fish growth. However, the conditions imposed by the aquaponic system were suitable for promoting lettuce’s growth and external appearance, as no pests or leaf discoloration were noticed. Lettuce survival was similar among the three tested varieties (98.5 ± 1.7%). The yields for the romaine and iceberg varieties were 384 ± 100 g/lettuce and 316 ± 70 g/lettuce, respectively, and that for the red leaf variety was lower, at 176 ± 75 g/lettuce. Yield values ranged between 3.6 and 4.4 kg/m2 depending on the replicate considered (4.0 ± 0.4 kg/m2). According to present results, each aquaponic unit required ca. 2.6–2.7 L of water per unit of lettuce produced. Full article

Interest in aquaponics (AP) is increasing due to its ability to minimize sewage and maximize feed efficiency in fish farming. However, owing to limitations of intensive cultures and a lack of nutrients such as NO3 for growing crops, AP requires the use of artificial nutrients. Therefore, novel approaches are required to develop AP-intensive culturing methods. An AP system based on biofloc technology (BFT) called FLOCponics (FP) has been recommended. Here, the productivity of the weather loach (Misgurnus anguillicaudatus) in the FP system, BFT system, and flow-through systems (FTSs), as well as these systems’ effect on Caipira lettuce (Lactuca sativa) growth, was analyzed. To compare crop productivity, a hydroponic (HP) bed was installed. The growth rate of M. anguillicaudatus showed significant differences, at 51.1 ± 3.69% in the FP system, followed by 24.0 ± 4.16% in the BFT system and −14.3 ± 1.4% in the FTS. Its survival rates were better in the FP system (91.1 ± 2.64%) than in the BFT system (82.1 ± 10.98%) or the FTS (66.8 ± 2.75%) (p < 0.05). Total ammonia nitrogen and NO2−-N concentrations were stabilized in every plot during the experimental period. However, the NO3−-N concentration continuously increased in the BFT system but decreased in the FP system and was maintained. The shoot weight of the Caipira lettuce was 163.6 ± 8.65 g in the FP system and 149.6 ± 9.05 g in the HP system. In conclusion, FP system can provide a large amount of nutrients and improve the growth performance of both fish and crops in the FP system. Full article

Stocking densities were evaluated for the rearing tambaqui in an RAS system. Experiment 1 used juveniles weighing 0.54 g at the following densities for 15 days: D0.3—0.3; D0.6—0.6; and D0.9—0.9 kg m−3. Experiment 2 used juveniles weighing 8.22 g at the following densities for 75 days: D0.8—0.8; D1.2—1.2; and D1.6—1.6 kg m−3. Experiment 3 used juveniles weighing 142.18 g at the following densities for 75 days: D2—2; D4—4 and D6—6 kg m−3. In Experiment 1, density did not influence performance (p > 0.05), with the exception of biomass, which was greatest in D0.9 (p < 0.05). In Experiment 2, final weight, weight gain and daily weight gain were highest for D0.8 (p < 0.05), as was triglycerides (p < 0.05), whereas biomass increased with increasing density (p < 0.05). In Experiment 3, weight, weight gain and daily weight gain were greater for D2 and D4 (p < 0.05), while final biomass was lowest for D2 (p < 0.05). Hemoglobin was lower for D4 and D6 (p < 0.05), while cholesterol and glucose levels were higher for D2 and D6 (p < 0.05). Colossoma macropomum demonstrated adaptive capacity for reared in RAS at high stocking densities. Full article
