“…() failed to obtain differences due to shrimp density at a lower level (20 vs. 100 shrimp/m 2 ). In contrast, lower levels of Arg‐P found in B and BS shrimp could be attributed to escape energy expenditure that organisms may have experienced during sampling as capture was more difficult in trouble waters, in accordance to a strong depletion of Arg‐P during escape response (Robles‐Romo et al., ).…”

“…Thus, it represents another important physiological tool affected by different stressors, such as high ammonia concentrations (Marazza, Bornens & Le Gal, 1996), hypoxia (Abe, Hirai & Okada, 2007), pH levels (Wang, Wang, Chen, Liu & Sun, 2002), escape response (Robles-Romo, Zenteno-Savín & Racotta, 2016) and exposure to white spot syndrome virus (Apún-Molina et al, 2017). A decreased level of arginine phosphate (Arg-P), an immediate source of energy for tissues, was also detected in several crustaceans under conditions of acute stress (Abe et al, 2007; Robles- Romo et al, 2016). One of the adverse effects of chronic stress, such as high density, is a decreased ability to cope with a subsequent second (generally acute) stressor.…”

The objective of this study was to assess zootechnical and physiological performance of Litopenaeus vannamei postlarvae (PL) reared in three environments (CW, clear water; B, biofloc; BS, biofloc with artificial substrates) at three stocking densities (300, 600, 900 PL/m3) for 8 weeks. At the end of experimentation, shrimp were subjected to hypoxia, and physiological response was again assessed. During rearing, low levels of total ammonia nitrogen, nitrite (NO2̄) and nitrate (NO3̄) were observed in B and BS for 600 and 900 PL/m3. For 300 PL/m3, a slight accumulation of NO2̄ and NO3̄ was detected. For the same stocking density, shrimp reared in B and BS showed significantly higher weights than those grown in CW, except for final weight. No significant differences were observed in survival. The use of biofloc and artificial substrates permitted doubling density from 300 to 600 PL/m3 without affecting growth, survival, feed conversion rate and obtaining twice the biomass. Shrimp grown in B and BS stored a surplus of glycogen and carbohydrates in their hepatopancreas, which probably gave them a better physiological capacity to counteract high‐stocking densities and hypoxia. A tendency of a higher adenylate energetic charge was observed in shrimp maintained in B and BS.

“…Frozen samples of adductor muscle were ground to a fine powder with a ball mill mixer (MM400, Retsch, Germany) that was precooled with liquid nitrogen. Nucleotides within the ground adductor muscle samples (100 mg) were extracted and processed according to the methods described by Moal et al 33 , with modifications as described by Robles-Romo et al 34 . Acidic extracts (200 µl) were neutralised with a mixture of dichloromethane and trioctylamine (5:1 v/v), after which they were passed through a 0.2 µm filter and then maintained at −80 °C until further analysis.…”

and balance, the response observed in adult scallops suggested that N. subnodosus presents a high capability to respond to acute temperature stress in the range of its thermal window tolerance. Our study examined the capability of scallops to respond to an acute challenge of 24 h, these results lead to additional unknowns regarding the metabolic and energetic capability of the response and homeostasis under repeated exposure to acute hyperthermia scenarios and regarding the increasing variability in seawater temperature as another possible large event in future global warming scenarios.

“…Lactate levels in muscle increased markedly as a result of stress, but no differences were found among diets in stressed or non-stressed shrimp ( Table 6). Lactate rise 30 min after a handling stress, sometimes followed with a glucose increase after 60 min has been reported in shrimp subjected to acute stress (Aparicio-Simón et al, 2010;Racotta, Palacios, & Ibarra, 2003;Robles-Romo, Zenteno-Savín, & Racotta, 2016). While levels of glucose in muscle were not significantly affected by diet or stress, a stronger depletion of glucose occurred in the hepatopancreas of shrimp fed the con- recovered quicker (less non-responsive shrimp) than the shrimp fed squid or the controls, indicating that the muscle was able to contract sooner after stress than in those fed the squid diet, and more so compared to the shrimp fed the control diet.…”

We substituted 10% of fishmeal with scallop (Argopecten ventricosus) or squid (Dosidiscus gigas) by‐product meal in a feed for shrimp (Litopenaeus vannamei) growth assay that lasted 60 days and then shrimps were submitted to handling stress. Shrimp fed the control diet had smaller weight gain and lower recovery after stress. Prostaglandins in gills were affected by diet and stress, with significant differences in shrimp fed the control diet before and after the stress. Hydroperoxides were increased after stress, while isoprostanoids were higher in shrimp fed the control diet. The gene expression of Glutathione peroxidase and Catalase was increased on the stressed shrimp fed the scallop diet, with no differences among diets for Superoxide dismutase or Cyclooxygenase. Arachidonic acid in the phospholipid fraction of muscle was the only fatty acid affected by stress and diet. Cholesterol oxidation products were significantly higher in shrimp fed the scallop diet compared to shrimp fed the control diet before applying the stress. A PCA analysis grouped in one‐factor growth variables, as well as Superoxide dismutase, esterified astaxanthin and isoprostane, while another factor was determined by stress, prostaglandin and hydroperoxide levels in gills. The partial substitution of fishmeal with scallop of squid by‐product meals affected growth and stress differently, indicating shrimp that grew up more were not necessarily more tolerant to handling stress, which can have a strong repercussion in aquaculture, particularly during density control, recording of growth and harvest.
