“…Several studies reported that fasting caused liver degeneration, decreased hepatocyte size, and enlargement of the sinus in Chanos Chanos juveniles , Amphiprion melanopus , and green sturgeon ( Acipenser medirostris ) (Storch and Juario 1983 ; Green and McCormick 1999 ). Moreover, steatosis, inflammation, degeneration, necrosis, and hyperemia with reduced liver tissue were all observed in rainbow trout ( Oncorhynchus mykiss ) (Karatas et al 2021 ), which could be related to impaired lipid transport, lipid biosynthesis, or both (Colakoglu and Donmez 2012 ), although the elevated blood flow, inflammation, necrosis, and enlargement of arterioles were all documented to be suggested reasons of hyperemia (Karataş et al 2019a , b ).…”

The current study investigated how different fasting and refeeding regimes would impact Nile tilapia growth performance, histopathological examination, and gene expression of myostatin, myogenin, GH, IGF-1, and NPYa. Nile tilapia fish (n = 120) were randomly allocated into four groups, including the control group fed on a basal diet for 6 weeks (F6), group A starved for 1 week and then refed for 5 weeks (S1F5), group B starved for 2 weeks and then refed for 4 weeks (S2F4), while group C starved for 4 weeks and then refed for 2 weeks (S4F2). Fasting provoked a decrease in body weight coincided with more extended starvation periods. Also, it induced muscle and liver histological alterations; the severity was correlated with the length of fasting periods. Gene expression levels of GH, MSTN, MYOG, and NPYa were significantly increased, while IGF1 was markedly depressed in fasted fish compared to the control group. Interestingly, refeeding after well-planned short fasting period (S1F5) modulated the histopathological alterations. To some extent, these changes were restored after refeeding. Restored IGF-I and opposing fasting expression profiles of the genes mentioned above thus recovered weights almost like the control group and achieved satisfactory growth compensation. Conversely, refeeding following more extended fasting periods failed to restore body weight. In conclusion, refeeding after fasting can induce a compensatory response. Still, the restoration capacity is dependent on the length of fasting and refeeding periods through exhibiting differential morphological structure and expressions pattern for muscle and growth-related genes.

“…Decreased protein levels of the fish after DMN exposure reported in previous studies may be because of increased energy demand for metabolism or degradation of protein synthesis during oxidative stress. Moreover, the increased degradation or proteolytic activity could result from decreased protein levels (Karatas, Yildirim, and Arslan, 2019; Karatas, Yildirim, Arslan, & Aggul, 2019). In our study, although decreased levels of protein and albumin were observed during DMN exposure, using LPEO with higher concentrations could have caused the increases in these parameters.…”

The purpose of this study was to investigate the dietary effects of using essential oil from sour lemon peel (Citrus limon) on growth performance, carcass composition, blood and serum parameters, and liver enzymes of juvenile rainbow trout (Oncorhynchus mykiss) exposed to deltamethrin (DMN) pesticide. Treatments with no lemon peel essential oil (LPEO) and without DMN (control), as well as four treatments with 10% of 96‐h lethal concentration of DMN were prepared with dietary supplementation of LPEO (zero, 200, 400, and 600 mg/kg). Trout juveniles (95.12 ± 0.53 g) were randomly allocated to the treatments (each with three replicates). The results showed that dietary LPEO inclusion improved fish growth parameters in the DMN‐containing treatments. The highest fat content was found in zero LPEO treatment with no DMN while it was lowest in DMN treatments containing 400 and 600 mg/kg of LPEO. Carcass protein content was the highest in DMN treatment with 400 mg/kg of LPEO. Blood and serum biochemical parameters showed statistical differences between no LPEO treatment with DMN exposure and those detected in the control fish (p < .05). Overall, the results indicate that dietary inclusion of LPEO at 400 mg/kg level can decrease some negative effects of DMN exposure.

“…DM caused behavioural effects including rapid swimming, loss of balance, aggressiveness and increases in the surface activity in brown trout (Salmo trutta) at concentrations as low as 1 µg/L (Karatas et al, 2019). Killi sh (Jenynsia multidentata) exposed to cypermethrin at (4 µg/L) showed a decrease in swimming activity and an increase in the time spent at the bottom of test tanks (Bonansea et al, 2016).…”

Lethal and sublethal effects in Pink salmon (Oncorhynchus gorbuscha) following exposure to five aquaculture chemotherapeutants

Early life stages of Pink salmon (Oncorhynchus gorbuscha) are at risk of exposure to the active ingredients of chemotherapeutant formulations (hydrogen peroxide [HP], azamethiphos [AZ], emamectin benzoate [EB], cypermethrin [CP] and deltamethrin [DM]) used to control sea lice in salmon aquaculture. LC50 values (95% con dence intervals) for acute 48-h water exposures in order of least to most toxic to seawater-adapted pink salmon fry were: mg/L), EB (1090EB ( [676-2006 µg/L), µg/L), ] µg/L), and DM (980 [640-1800] ng/L). In subchronic 10-d lethality sediment exposure tests, LC50 values (95% con dence intervals) in order of least to most toxic were: EB (2065 [1384-3720] µg/kg), µg/kg), and DM (1035DM ( [640-2000 ng/kg). Alterations in behaviour varied between chemicals; no chemical attracted pink salmon fry; sh avoided HP to a limited extent at 50 mg/L), as well as EB (300 µg/L), and AZ (50 µg/L). Signi cant concentration-dependent decreases in olfactory responsiveness to food extract were seen following AZ, CP and DM exposures that occurred at lower concentrations with longer exposure periods (10 µg/L, 0.5 µg/L and 100 ng/L thresholds at 168 h). Following 10-d sediment exposures, olfaction was only affected by CP exposure at 50 µg/kg. Signi cant decreases in swimming performance (Ucrit) occured for HP, AZ, CP and DM at concentrations as low as 100 mg/L, 10 µg/L, 2 µg/L and 200 ng/L, respectively. This study provides comprehensive data on the lethal and sublethal effects of aquaculture chemotherapeutant exposure in early life stage pink salmon.
