To initiate anaesthesia, fish were immersed in ice water (1 litre) with 40 mg l −1 of the general anaesthetic tricaine methanesulfonate (MS‐), until fish ceased to swim, lost equilibrium and were unresponsive to a pinch on the tail (typically 10–15 min). They were next treated with topical anaesthetic (20% benzocaine gel; Ultradent Cited by: 4.

    Laboratory experiments were conducted to study the effects of dehydro-abietic acid (DHA) on the physiology of the adaptation of sockeye salmon smolts (Oncorhynchus nerka) to sea water. Dehydroabietic acid occurs in the rosin of commercially important coniferous trees and is found in the untreated effluents of the pulp and paper industry at concentrations acutely toxic to salmonids.

Because MS desensitizes sero-sal tissues, Letcher also concluded the injection to be relatively painless.

Benzocaine has been used in a similar manner to MS Benzocaine is similar to MS as an anes. Benzocaine (ethyl para-aminobenzoate), a mammalian local anesthetic, is an effective general anesthetic agent for fish when administered by bath exposure.

Its proposed use in aquaculture is to sedate fish and reduce mortality during transport and/or spawning operations in hatcheries or during stocking by: 4. Animals, housing, and husbandry. The Xenopus laevis studied were all sexually mature, adult female frogs [age, 2 to 3 y; body weight (mean ± 1 SD), ± g; snout-to-vent length, ± cm] previously scheduled for euthanasia.

All frogs were housed in dark-green, opaque, bathtub-style tanks (width, 4 ft; length, 6 ft; height, 4 ft), and filled with L dechloraminated potable by: In the classical tadpole assay employed for Meyer-Overton type correlations, tricaine and benzocaine are 7–8 times more potent than n-alkanols of equi Cited by: 4.

This is a list of cocaine analogues.A cocaine analogue is a (usually) artificial construct of a novel chemical compound from (often the starting point of natural) cocaine's molecular structure, with the result product sufficiently similar to cocaine to display similarity in, but alteration to, its chemical function.

Within the scope of analogous compounds created from the structure of cocaine. A higher concentration of MS is required to induce anesthesia in Peaaeus indicus, than that in fish (Akbari and Khajavi, ).

Aqui-S has been reported to be effective in freshwater prawn, but only at concentrations of 5 to 10 times greater than those used in finfish (Coyle et al., ). Carbon dioxide is an effective anesthetic for most.

Study design. Zebrafish enrolled in the study were older than 6 mo and were euthanized individually by immersion in 1 of 2 water baths.

The fish (n = 23 for each solution) were placed in a spawning barrier, which was submerged in a 1-L holding tank (Figure 1) containing approximately equal amounts ice and water at a temperature of 2 to 4 °C (36 to 39 °F; as determined by a bulb thermometer Cited by: aquaculture are MS (tricaine methane sulphonate), benzocaine (ethly-p-aminobenzoate), methomidate, clove oil, eugenol and 2-phenoxyethanol (ethylen glycol monophenyl ether) (Velisek et al.,).

Currently, only MS is licensed for use in food fish in the USA and the European Union. Also, Aqui S has a huge usage ratio. This agent is considered to be a local anesthetic, although it acts systemically in fish.

Bath exposure with MS was not considered genotoxic, when detected by comet assay, when evaluated in juvenile fish. Besides, MS and benzocaine are analogues of procaine (typically used as local anesthetics in Cited by: 6.

MS appears to be one of the most reliable anaesthetics. This review will focus on the evidence of pain perception in frogs and will compare the effectiveness and limitations of different anaesthetics used in Xenopus leavis frogs.

The higher molecular weight of the formulation would be expected to yield an anesthetic less active than the benzocaine formulation. AFS‐FHS (American Fisheries Society‐Fish Health Section).
