“…This kind of result is similar to cortisol and blood glucose level increase at 60 th and 90 th minute on tilapia after electric shock (Barreto & Volpato, 2006), similarly when tilapia is injected with different anesthesia during stress level test (Navarro et al, 2016). This result was also shown on common carp which experienced cortisol increase, but insignificantly after a 12-hour transport (Dobsikova et al, 2009).…”

“…Repeating and prolonged stress condition might become negative influence towards growth and developing level, immunity, and reproduction mechanism (Schreck & Tort, 2016). Decreasing on stress level during transportation is a crucial aspect to support survival rate and growth performance (Navarro et al, 2016). This aspect can be done through feed supplementation, one of them is chromium (Cr) supplementary in the feed.…”

This study was conducted to evaluate stress responses of transportation on red tilapia Oreochromis sp. which given feed containing chromium. Three isonitrogenous and isocaloric experimental feeds were prepared, these diets were control (without chromium), CrPic 1 mg/kg, and CrYst 2 mg/kg supplementation in feed, all group were arranged triplicate. Satiation feeding was done three times a day. After a 60-day feeding experiment, the experimental fishes were fasted and distributed in polyethylene bags (N=60 fish/bag) containing 3 L of water, subjected to condition of transport simulation for 13 hours. Survival rate, levels of plasma cortisol, blood glucose, superoxide dismutase (SOD), and malondialdehyde (MDA) enzyme were observed at before transportation, after transportation, one day, and two days after transportation. The result showed that chromium supplementation reduced the levels of plasma cortisol before and after transportation, one day, and two days after transportation. Also, it decreased blood glucose compared with control significantly before transportation and one day after transportation. The SOD enzyme concentration increased significantly after fish was fed with feed containing chromium for 30 days, while the MDA enzyme concentration increased significantly after two days of transportation. However, there was no significant difference in the survival of red tilapia between treatments. The best result was obtained in the treatment of fish which fed with feed containing chromium. A 1 mg/kg of CrPic supplementation and 2 mg/kg CrYst increased the body resistance in red tilapia by decreasing the negative effect of stress while transportation.Keywords: stress, transportation, red tilapia, chromium ABSTRAKPenelitian dilakukan untuk mengevaluasi respons stres transportasi ikan nila merah Oreochromis sp. yang diberikan pakan yang mengandung kromium. Pada penelitian ini digunakan tiga jenis pakan, terdiri atas pakan tanpa suplementasi kromium (kontrol), pakan bersuplementasi kromium pikolinat (CrPic 1 mg/kg), dan kromium yeast (CrYst 2 mg/kg), semua perlakuan diulang sebanyak tiga ulangan. Pemberian pakan sebanyak tiga kali sehari dan dilakukan secara at satiation. Setelah 30 hari pemeliharaan, ikan uji dipuasakan dan didistribusikan dalam plastik polietilen (N=60 ekor ikan/kantong plastik) yang berisi 3 L air, dilakukan dengan simulasi transportasi selama 13 jam. Parameter yang diamati pada penelitian ini adalah kelangsungan hidup, kortisol, glukosa darah, enzim superoksida dismustase (SOD), dan malondialdehida (MDA) saat sebelum transportasi, sesaat setelah transportasi, sehari, dan dua hari setelah transportasi. Hasil yang didapatkan adalah suplementasi kromium menurunkan konsentrasi kortisol secara signifikan sebelum transportasi, sesaat, sehari, dan dua hari setelah transportasi. Suplementasi kromium menurunkan glukosa darah secara signifikan pada saat sebelum transportasi dan sehari setelah transportasi. Konsentrasi enzim SOD meningkat secara signifikan setelah pemberian pakan bersuplementasi ...

“…With a fixed number of animals available and their welfare in mind, handling was designed to acquire samples with the least amount of anticipated stress for each species and their perceived levels of tolerance to restraint stress. The use of anesthetics has been shown to reduce stress in teleosts ( 43 – 45 ), although responses are varied and contingent on species and circumstance ( 46 , 47 ). While MS222 can induce cortisol release and alter some other biochemical values in trout ( 47 – 50 ), it has been shown that it reduces the stress response overall ( 45 ).…”

Pharmacokinetics of Ketoprofen in Nile Tilapia (Oreochromis niloticus) and Rainbow Trout (Oncorhynchus mykiss)

The objective of this study was to document the pharmacokinetics of ketoprofen following 3 mg/kg intramuscular (IM) and intravenous (IV) injections in rainbow trout ( Oncorhynchus mykiss ) and 8 mg/kg intramuscular (IM) injection in Nile tilapia ( Oreochromis niloticus) . Plasma was collected laterally from the tail vein for drug analysis at various time intervals up to 72 h following the injection of ketoprofen. In trout, area under the curve (AUC) levels were 115.24 μg hr/mL for IM and 135.69 μg hr/mL for IV groups with a half-life of 4.40 and 3.91 h, respectively. In both trout and tilapia, there were detectable ketoprofen concentrations in most fish for 24 h post-injection. In tilapia, there was a large difference between the R- and S-enantiomers, suggesting either chiral inversion from R- to S-enantiomer or more rapid clearance of the R-enantiomer. AUC values of the S- and R-enantiomers were 510 and 194 μg hr/Ml, respectively, corresponding to a faster clearance for the R-enantiomer. This study shows that there were very high plasma concentrations of ketoprofen in trout and tilapia with no adverse effects observed. Future studies on the efficacy, frequency of dosing, analgesia, adverse effects, and route of administration are warranted.

“…However, the higher the concentration of this sugar in the blood, the greater the stressful condition of the animal (Eslamloo et al, 2014). Glucose elevation was also observed in tilapia after fish were submitted to other stressors (Moreira et al, 2015;Navarro et al, 2016).…”

Oscillatory movements present in the transport of live fish may compromise the physiological stability and the future performance of the animals. Therefore, the objective of this research was to evaluate the effect of mechanical vibrations in the transport of Nile tilapia through vibration levels and shocks occurred in transport boxes previously installed in a truck. The research was carried out in a fish farming integrating company in the state of Ceará, Brazil, with the monitoring of 5 live fish loads. The transport truck used was of the open type, with capacity for five boxes of fiberglass with a useful volume of 2400 L, density of 236 kg m-3. The data were recorded through five dataloggers, to monitor the vibration level (m s-2) and the occurrence and amplitude of mechanical shocks on the roads. Hematological, metabolic and ionic responses of fish were evaluated as well as visual observations of physical injuries. The most intense shocks occurred with the truck between 60 and 80 km h-1, with vibrations 1.151 m s-2 in the transport box, as well as in the water 0.489 m s-2. Larger vibration levels occurred on the asphalt road, with an average value of 1.13 m s-2, while on the dirt road they registered an average of 0.57 m s-2. Vibratory and mechanical stimuli presented secondary responses to blood level stress with alterations in glycemia, hematocrit, hemoglobin and magnesium ions. Physical lesions with 34% severe and 21% moderate, showed an uncomfortable environmental condition to fish.
