“…Azim and Little () reported that survival and welfare indicators indicated the presence of flocs (average TSS level was 597 mg/L) did not increase tilapia stress. It demonstrated that an average TSS level of 2,054 mg/L had no harm to the survival and growth performance of Litopenaeus vannamei (Gaona, da Paz Serra, Furtado, Poersch, & Wasielesky, ). However, previous studies had enhanced that high concentrations of TSS increased the cost of aeration in order to maintain DO concentrations, especially during the later culture period (Ebeling et al., ; Gaona, de Almeida, Viau, Poersch, & Wasielesky, ; Gaona et al., ).…”

In this study, GLU‐tanks need more aeration rate than NCA‐tanks after day 30, which was consistent with the previous reports.…”

Effect of no carbohydrate addition on water quality, growth performance and microbial community in water-reusing biofloc systems for tilapia production under high-density cultivation

et al. 2018

A 56‐day experiment was conducted to investigate the effect of no carbohydrate addition applied to control water quality in water‐reusing biofloc systems for tilapia (GIFT Oreochromis niloticus) cultivation. Reusing water‐contained flocs was initially inoculated into six 300 L indoor tanks. Thirty fish (average individual weight 99.62 ± 7.34 g) were stocked in each tank. Glucose was extra added into three tanks (GLU‐tanks) according to biofloc technology, while other tanks were no carbohydrate added (NCA‐tanks). Concentrations of total ammonia nitrogen in GLU‐tanks and NCA‐tanks were fairly consistent and below 4.74 ± 0.35 mg/L. Nitrite concentrations in NCA‐tanks were significantly lower than GLU‐tanks, which were below 0.59 ± 0.10 mg/L during the later culture period. NCA‐tanks achieved a low relative abundance of denitrifiers and high concentrations of nitrate. Soluble reactive phosphorous in NCA‐tanks was consistently increased, which was decreased to a low level in GLU‐tanks. However, growth parameters in NCA‐tanks were similar to GLU‐tanks (p > .05) and reach a high finial density of 24.32 ± 1.04 kg/m3. Cetobacterium sp. was the first‐dominant bacterial genus in all tanks, which was a commonly indigenous bacterium in the intestinal tract of freshwater fish. The results demonstrate the feasibility of no carbohydrate addition in water‐reusing biofloc systems for tilapia.

“…The development of productive techniques such as the bioflocs and recirculation systems, which allow high storage densities, has leveraged and opened precedents for this scenario to be increasingly consolidated (Avnimelech & Ritvo, 2003;Crab, Avnimelech, Defoirdt, Bossier, & Verstraete, 2007;Dalsgaard et al, 2013;Kim, Ee, Kim, & Park, 2006;Vinatea et al, 2018;Wasielesky, Atwood, Stokes, & Browdy, 2006). Accompanying this trend has sought methods of working with alternatives that help in mitigating the challenges generated by increasing the capacity and enhancement of systems for the rearing of aquatic organisms, including higher stress and health problems (De Souza et al, 2016;Gaona, Paz Serra, Furtado, Poersch, & Wasielesky, 2016;Glencross et al, 2016;Panini et al, 2017;Macias-Sancho et al, 2017;Torrecilas et al, 2017;Wang, Wang, Zhang, & Song, 2017). Exposure to environmental stressors such as temperature, pH, light, oxygen, salts, pollutants and pathogens is an unavoidable aspect of aquaculture practices (Wang, Wang, & Wang, 2006).…”

This study investigated the effects of the inclusion of Mauritia flexuosa fruit pulp in the diet on the growth performance, economic benefit, muscle composition, total contents of carotenoids and flavonoids, chromaticity parameters, total antioxidant capacity, and lipid peroxidation in the hepatopancreas and muscle of the juvenile shrimp Litopenaeus vannamei (weighing 1.26 ± 0.023 g). Five diets (37% protein, 10% lipid) consisting of 0 (control), 1.25%, 2.50%, 5.00% and 10.00% (w/w) M. flexuosa fruit pulp were formulated and provided to the shrimps (n = 50 per tank, treatments in triplicate) for 31 days. Results showed that there were no significant differences between the treatments in terms of the growth capacity, chromaticity parameters, muscle composition and total flavonoid content of shrimps (p > .05). However, the carotenoid content in the muscle and hepatopancreas of the shrimps was significantly increased due to the dietary carotenoids present in M. flexuosa fruit pulp (p < .05). This increase in the carotenoid content directly favoured the increase in the antioxidant capacity in the hepatopancreas and muscle of the shrimps (R2 = 0.99 and R2 = 0.97 respectively; p < .05). There was also a direct relationship between the carotenoid content and the decrease in lipid peroxidation in the hepatopancreas (R2 = 0.90; p < .05). The feed cost kg−1 in terms of weight gain and protein production decreased with the inclusion of high levels of M. flexuosa fruit pulp, reaching 8.11% and 18.76% of cost reduction, respectively, with the addition of 5.00% of M. flexuosa fruit pulp. Therefore, the inclusion of M. flexuosa fruit pulp in the diets of shrimp can increase the carotenoid content and the antioxidant capacity in the hepatopancreas and muscle, reduce lipid peroxidation in the hepatopancreas, and probably provide economic benefits for the rearing of juvenile shrimps.

“…However, a subsequent study conducted by Gaona et al . () indicated that suspended solids (250~4000 mg L −1 ) did not seem to affect shrimp growth at high dissolved oxygen levels (above 5 mg L −1 ). This difference may be due to factors, such as the stocking density, shrimp size, system configuration and feed type, which should be further explored.…”

The generation of solids by aquaculture activities has led to many problems in animal welfare, environmental quality, water treatment effects and public health, such as gill and intestinal damage, water eutrophication, system components blockages and antibiotics transfers through the food chain to human; thus, effective solid wastes management is very important. The purpose of this review is to summarize the sources, characterization methods, harmfulness, removal technologies and reutilization of solids in aquaculture water, including (i) different sources of solids, such as uneaten feed, feces and debris; (ii) solids characterization based on the general parameters, particle size distribution and chemical composition; (iii) the toxicity and detriment of solids to cultured species, the environment, aquaculture system components and human health; (iv) Solids removal, effluents solids thickening and source control techniques for better solids management; and (v) various methods for the reutilization of aquacultural solid wastes for resource value-adding. In addition to these five specific objectives, the merits and drawbacks of each method or technology and future research priorities are discussed. The present review provides an understanding of the role played by solids in aquaculture water and provides guidance for aquacultural solid wastes precision management, aquaculture practices and technological developments. Thus, solids management can be carried out based on this guidance to improve animal welfare and the stability of water treatment systems, reduce harm to the environment and public health, and enable the development of aquaculture in a sustainable way.
