“…Each tank was additionally equipped with a 1‐HP centrifugal pump (BCR 2000, Schneider Motobombas, Joinvile, Brazil) for water circulation and two air injectors (a 3 , All‐Aqua Aeration™, Lake Mary, FL). The a 3 injectors are an alternative to Venturi system; they operate in a similar way but produce a much higher air‐to‐water ratio, up to 3:1 (Samocha et al, 2017).…”

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.

“…Intensification has not only been used for the grow-out phase of shrimp farming, but also for the nursery phase [88]. The shrimp nursery phase is a period of rearing between hatchery and grow-out, in which the post-larvae are maintained in special facilities for approximately 15 to 40 days, in one or two sub-phases (e.g., 14 + 28 days), and under high stocking densities (1500 up to 20,000 PL m −3 ) [4].…”

Intensification of the shrimp sector, also referred to as vertical expansion, has been predominately driven by consecutive incidences of global disease outbreaks, which have caused enormous economic loss for the main producer countries. A growing segment of the shrimp farming industry has opted to use production systems with higher density, biosecurity, and operating control to mitigate the risks posed by disease. However, successful super-intensive shrimp production is reliant on an advanced understanding of many important biological and economic parameters in the farming system, coupled with effective monitoring, to maintain optimal production. Compared to traditional extensive or semi-intensive systems, super-intensive systems require higher inputs of feed, energy, labor, and supplements. These systems are highly sensitive to the interactions between these different inputs and require that the biological and economical parameters of farming are carefully balanced to ensure success. Advancing nutritional knowledge and tools to support consistent and efficient production of shrimp in these high-cost super-intensive systems is also necessary. Breeding programs developing breeding-lines selected for these challenging super-intensive environments are critical. Understanding synergies between the key areas of production systems, nutrition, and breeding are crucial for super-intensive farming as all three areas coalesce to influence the health of shrimp and commercial farming success. This article reviews current strategies and innovations being used for Litopenaeus vannamei in production systems, nutrition, and breeding, and discusses the synergies across these areas that can support the production of healthy and high-quality shrimp in super-intensive systems. Finally, we briefly discuss some key issues of social license pertinent to the super-intensive shrimp farming industry.

“…The carbon:nitrogen ratio is maintained through the addition of a source of organic carbon, which is used by bacteria to convert TAN (Total Ammoniacal Nitrogen) to bacterial biomass (Ebeling et al, 2006). Among the various sources of carbon, molasses is widely used because it stains water, reducing light penetration and associated algal growth, however, may present high level of impurities and content variability (Samocha et al, 2017). In addition, molasses is an inexpensive source of carbon used for various industrial fermentations (Miranda et al, 1996;Najafpour and Shan, 2003).…”

TILAPIA CULTIVATED IN A LOW-SALINITY BIOFLOC SYSTEM SUPPLEMENTED WITH <i>Chlorella vulgaris</i> AND DIFFERENTS MOLASSES APPLICATION RATES

The aim of this study was to evaluate the effect of supplementation with Chlorella vulgaris and molasses application rates on water quality, zootechnical performance, proximate composition and health status of Nile tilapia (Oreochromis niloticus) fingerlings cultivated in low-salinity (10 g L-1) biofloc systems. Four treatments were tested in a factorial design (supplemented with microalgae and molasses application rates): BFT-C30 (Biofloc supplemented with C. vulgaris and molasses application rates of 30% of the total daily feed); BFT-30 (Biofloc with molasses application rates of 30% of the total daily feed); BFT-C50 (Biofloc supplemented with C. vulgaris and molasses application rates of 50% of the total daily feed) and BFT-50 (Biofloc with molasses application rates of 50% of the total daily feed), for 70 days. Fingerlings of O. niloticus (initial mean weight of 3.15 ± 0.5 g) were stocked at a density of 680 fish m-3 in experimental units (50L), where 50% of this volume was biofloc previously matured. Throughout the experiment, they were supplemented with C. vulgaris every five days at the concentration of 5x10 4 cells mL-1. A significant interaction between supplementation with C. vulgaris and molasses application rates for final weight and length, survival, feed conversion ratio, specific growth rate, water consumption, protein efficiency ratio, sedimentation time, planktonic community and hematological indices were observed. The results indicated that the high molasses application rates (50%) in the biofloc system affects the zootechnical performance, water consumption, sedimentation time and the hematological indices of the Nile Tilapia fingerlings, hampering their development. Therefore, molasses application rates of 30% of the total daily feed for the tilapia fingerlings culture in low-salinity biofloc system is recommended.
