“…However, the formation of gas bubbles observed in salmon lice (Bruno and Raynard 1994) was not reported in Acartia hudsonica, Metacarcinus edwardsii, or in Calanus spp. (Van Geest et al 2014;Gebauer et al 2017;Hansen et al 2017), so the mechanism of immobilization observed in Calanus spp. is unclear.…”

Hydrogen peroxide (H2O2), a pesticide used in salmonid aquaculture, is released directly into the environment where nontarget organisms are at risk of exposure. We determined threshold concentrations for mortality of Calanus spp., the dominant zooplankton species in the North Atlantic, and assessed sublethal effects, focusing on the escape response and oxygen consumption rates (OCRs) as behavioral and physiological assays. One-hour exposure to 170 mg·L−1 (i.e., 10% of the recommended H2O2 treatment) was lethal to copepodite stage V (92% mortality) and adult females (100% mortality). The acute median lethal concentration (1h-LC50) was 214.1 (150.67–277.4) and 48.6 (44.9–52.2) mg·L−1 for copepodite V and adults, respectively. The 25-h LC50 was 77.1 (57.9–96.2) and 30.63 (25.4–35.8) mg·L−1 for copepodite V and adults, respectively. At concentrations of 0.5% and 1% of the recommended treatment level, Calanus spp. showed a decrease in escape performance and lower OCRs with increased concentration. At H2O2 concentrations of 5% of the recommended treatment levels (85 mg·L−1), exposed copepods showed no escape reaction response. These results suggest that sublethal concentrations of H2O2 will increase the risk of predation for Calanus spp. Furthermore, this study provides supporting evidence that theoretical “safe” values, traditionally used for predicting toxicity thresholds, underestimate the impact of H2O2 on the physiological condition of nontarget crustaceans.

“…were considerably more sensitive with a LC 50 of 973 mg•L −1 (i.e., lower than the recommended treatment concentration (Burridge et al 2014)) and late copepodide stage Calanus spp. had a LC 50 of 6 mg•L −1 H 2 O 2 following a 24-h exposure, indicating a timedependent effect (Hansen et al 2017).…”

“…In the studies of Burridge et al (2014), Brokke (2015), Escobar-Lux (2016) and Fagereng (2016), either the commercial H 2 O 2 formulation Nemona (Akzo Nobel) or Paramove (49.5%, Solvay Chemicals International) was used. In comparison, Hansen et al (2017) used Perhydrol, a 30% pro-analysis product from Merck, in their study. Whether there may be differences in the toxicity, first between the 2 antisea lice products and second between those products and the pro-analysis product, has to our knowledge not been investigated.…”

The amount of hydrogen peroxide (H 2 O 2) used in the treatment of salmon lice in Norwegian salmon farming increased from 308 tons in 2009 to 43 246 tons in 2015. For 2016 and 2017, however, the consumption was reduced to 26 597 and 9277 tons, respectively. The use of this compound may have negative impacts on benthic fauna underneath the fish farms and, in particular, on polychaetes, which can be found in large numbers at the bottom under fish farms where they play a key role in the turnover of organic waste from the farm. The tolerance of Capitella sp. and Ophryotrocha spp. to a 1 h exposure to H 2 O 2 (0, 100, 200, 400, 800, 1200 and 1800 mg l −1) was evaluated. The recommended dose for treatment of the salmon is 1800 mg l −1. Following exposures, the polychaetes were reintroduced into clean sea water. Both polychaete species experienced high cumulative mortality during a 72 h post-exposure period. The mortality showed to be dose dependent, with the highest dose giving the highest mortality. The 50% lethal concentration (LC 50) of Capitella sp. was significantly higher than the LC 50 of Ophryotrocha spp. at the same exposure time (p < 0.05). The 50% lethal time of Capitella sp. was significantly longer than that of Ophryotrocha spp. at the same concentration (p < 0.05). The results show that 1 h exposures to H 2 O 2 at all the tested concentrations had irreversible negative effects on both polychaete species.

Background: Field cricket (Gryllus bimaculatus) is newly emerged as an edible insect in several countries. Antiinflammatory effect of glycosaminoglycan derived from this cricket on chronic disease animal model such as diabetic mouse has not been fully investigated yet. Thus, the objective of this study was to determine the antioxidative effect of such glycosaminoglycan on diabetic mouse. Methods: To discover potential therapeutic agents, field cricket glycosaminoglycan (GbG) was tested in the present study. Its anti-oxidative activities in diabetic mice were determined based on its abilities to reduce glucose, ALT, AST, ALP, LDL-cholesterol and BUN levels. Dung beetle (C. molossus) glycosaminoglycan (CaG) was used as a positive control. Db mice were intraperitoneally administered for 1 month according to their group assignments: 1) normal (DB-Hetero); 2) control (DB-Homo); 3) 5 mg/kg treatment of CaG (CaG5); 4) 5 mg/kg treatment of GbG (GbG5); and 5) 10 mg/kg treatment of metformin (Metformin 10). Results: Blood glucose level decreased after 1st week of treatment with GbG. LDL-cholesterol and alkaline phosphatase levels were also inhibited by GbG. Markers of oxidative damage, such as protein carbonyl content and levels of hepatocellular biomarkers, were reduced in db mice treated with GbG. Especially anti-oxidative activities of catalase, superoxide dismutase and glutathione peroxidase were significantly increased in GbG treated group compared to those in the control (Db Homo). GbG was composed of heparin disaccharides. Its main N-glycan was identified as Hex 9 GlcNAc 2 (m/z 1905.7) with neutral mono-sugar mainly comprising of hexose and L (+) rhamnose by mass spectroscopy. Conclusions: Sero-biochemical and hepatocellular anti-oxidant assay results in db mice suggest that cricket (G. bimaculatus) glycosaminoglycan might possess anti-oxidative effect in diabetic state.
