“…There was an increase in the density and diversity of the planktonic community along the culture period, which is correlated to this gradual accumulation of nutrients in the system, as also reported by Marinho et al (2014) and Campos et al (2019). These differences were emphasized in the Cluster and ANOSIN cluster analysis.…”

“…The relative abundance revealed that about 67% of the phytoplankton was composed by the Cyanophyta group, as reported by other studies (Campos et al, 2019; Marinho et al, 2014), however, the densities in this study were lower than those found in other studies. This predominance of Cyanophyta is related to their capacity to fix nitrogen present in the environment, favouring their growth in relation to other phytoplankton groups.…”

The objective of this study was to evaluate the effect of the addition of Brachionus plicatilis to Litopenaeus vannamei in a nursery biofloc technology (BFT). Four treatments were used: BFT (without addition of rotifers); BFT‐10 (addition of 10 rotifers mL−1); BFT‐20 (addition of 20 rotifers mL−1) and BFT‐30 (addition of 30 rotifers mL−1), all in triplicate. The shrimp (3.4 ± 0.02 mg) were reared for 42 days at a density of 3000 shrimp m−3. The rotifers were added every 10 days (from day 1 to 30). The final weight (1.26 g) and yield (3.42 kg m−3) were significantly higher at BFT‐30 than those from BFT. The percentage of sucrose‐fermenting gram‐negative bacteria increased and non‐sucrose‐fermenting gram‐negative decreased by the end of the period. The crude protein of bioflocs was significantly higher at BFT‐30 than those from BFT‐10 or BFT treatments, while crude lipid of bioflocs was significantly higher at BFT‐20 and BFT‐30 than the BFT. The best shrimp performance was observed in BFT‐30 and BFT‐20, indicating the benefits of rotifers on enhancing the microbial floc content and growth to L. vannamei in BFT.

“…This was seen in January when chlorophyll and NO 3 − levels decreased (Figure 2c, a) and when the lowest phytoplankton density was found (Figure 3a). Campos et al (2019) also found a positive correlation between these groups in an aquaculture system.…”

The aim of this study was to evaluate the influence of shrimp farming on the phytoplankton community of a nearby shrimp estuary in Northeastern Brazil during a single cultivation cycle. Samples were collected from shrimp ponds and the estuary to analyse water quality variables, ecological indices and phytoplankton assemblages in both areas. Significant differences between sampling sites and over time were found for all variables. Phytoplankton density, orthophosphate and chlorophyll a content were lower in the estuary than in the ponds and were in accordance with Brazilian environmental law. Cyanophyta was abundant in the estuary and dominant in the shrimp ponds. Moreover, a significant positive correlation was found between Cyanophyta and orthophosphate. Thus, the influence of shrimp farming on the phytoplankton community was minimal or nil in the nearby estuary, as lower cell densities, a lower quantity of nutrients (especially orthophosphate) and better ecological health were found in the estuary than in the shrimp farm ponds. These findings contribute to a better understanding of the ecological balance in water bodies adjacent to aquaculture areas. Further studies should address the influence of wastewater from other aquaculture activities on the equilibrium of aquatic ecosystems.
