“…Survival showed equal values between alkalinity and concentrations in clear water and biofloc systems. These results (100.00%) were higher than those observed by AUDELO-NARANJO et al (2012) and FRÓES et al (2013) which cultivated juvenile L. vannamei in systems without water renewal for 40 days and 3 months (values from 97 to 95%), respectively.…”

This study aimed to evaluate the effect of alkalinity on food consumption and other performance parameters of juvenile Litopenaeus vannamei reared in water containing biofloc and clear water. For this purpose, shrimp of 4.06 ± 0.34 g were kept in containers of 3 L of biofloc and clear water during 3 days, with the concentrations of 50, 100 and 200 mg L-1 of alkalinity, plus a Control group, with 5 replicates each group. Food consumption was verified once a day and other performance parameters were evaluated at the end of the experiment. The food consumption and survival rates of the shrimp was not affected by the different levels of alkalinity and clear water and biofloc systems. The best results of weight gain and specific growth rate were observed in the highest concentrations of alkalinity in the biofloc system. Survival, as well as food consumption, was not affected between levels of alkalinity and in clear water and biofloc. The exposure to inappropriate alkalinity concentrations over long periods of time can adversely affect the animals, thus emphasizing the importance of maintaining adequate levels of alkalinity to the cultivated species.

“…Several researchers also found decreased survival rate with increasing stocking density in the production of freshwater prawn (El-Sherif & Mervat, 2009;Paul et al, 2016) and marine shrimp (Krummenauer et al, 2011;Fróes et al, 2013;Wasielesky et al, 2013) in different farming systems. The increase in stocking density interferes with hierarchical competition and disputes for space and food, resulting in higher cannibalism (Sampaio & Valenti, 1996;Arnold et al, 2006;Moraes-Valenti et al, 2010).…”

ABSTRACT. The objective of this study was to evaluate the effect of stocking densities on productive performance of the freshwater prawn Macrobrachium rosenbergii in biofloc system. Experimental tanks (microcosms) with 0.20 m² area were used as experimental units. The tanks were connected to two 300 L matrix tanks (macrocosm) with biofloc technology, used as recirculating units. M. rosenbergii juveniles, with an initial weight of 0.315 ± 0.06 g and initial length of 33.34 ± 2.26 mm, was randomly distributed in the experimental tanks at different stocking densities (50, 100, 150, 200 and 250 ind m -²) and reared during 60 days. The total biomass at the end of the experiment was significant higher (P < 0.05) with the use of higher stocking density (250 ind m -2 ). However, prawns stocked at the density of 50 m -2 showed significant higher (P < 0.05) survival (73%) and significantly lower values (P < 0.05) for feed conversion rate (1.28). The different stocking densities evaluated did not affect the weight and length of prawns. The recommended density for growing M. rosenbergii in the biofloc system is 50 ind m -2 .

“…Technological innovation permits increases in shrimp production capacity per unit area and renders the necessary biosecurity investment feasible. The addition of new tools such as specially designed injectors for these systems, artificial substrate, or clarifiers may allow unprecedented increases in the load capacity; however, these increases in stocking density can directly affect shrimp performance (Fróes, Fóes, Krummenauer, Poersch, & Wasielesky, 2013; Rego, Sabbag, Soares, & Peixoto, 2017). Krummenauer et al (2016) tried to solve this problem by altering the water volume in culture to lower depth (shrimp/m 3 ) in order to increase the yield (kg/m 3 production), which represent an option that could lead to other risks such as nitrite toxicity or solids accumulation.…”

Searching for potential increases in shrimp yields, this study evaluated the effects of different stocking densities on water quality and production performance of juvenile shrimp, Litopenaeus vannamei, reared on a biofloc-dominated system throughout 77 days. The organisms (1.27 ± 0.54 g) were stocked at three densities, 400 (T400), 500 (T500), and 600 (T600) shrimp/m 2 corresponding to 500, 625, and 750 shrimp/m 3 , with three replicates each, in nine 35 m 2 tanks with 28 m 3 of workable volume inside a greenhouse. Shrimp were maintained at optimal conditions for the species with an average temperature of 28.9 ± 0.1 C, dissolved oxygen average above 6.0 mg/L, and pH above 7.3. Significant differences in yields (3.52 ± 0.05, 4.02 ± 0.06 and 4.22 ± 0.40 kg/m 2 or 4.39 ± 0.07, 4.48 ± 0.08, and 5.27 ± 0.49 kg/m 3) were observed between treatments (T400, T500, and T600, respectively), and for final mean weights (12.3 ± 5.53, 12.2 ± 3.89, and 10.2 ± 3.49 g, respectively). These results suggest that 500 shrimp/m 2 or 625 shrimp/m 3 is the optimum stocking density for Biofloc Technology culture under the defined study conditions.
