TLDR
Rainbow trout (Salmo gairdneri) anesthetized with M.S. 222 for periods up to 12 min experience interrenal ascorbate depletion, uremia, and moderate hypercholesterolemia, and significantly reduced the variability in plasma glucose, cholesterol, and cortisol, indicating that the stress of anesthesia with M .S.222 is due to the low pK of the sulfonic acid moiety.Abstract:
Rainbow trout (Salmo gairdneri) anesthetized with M.S. 222 for periods up to 12 min experience interrenal ascorbate depletion, uremia, and moderate hypercholesterolemia. Anesthesia with neutralized M.S. 222 (pH 7) or benzocaine prevented these changes and significantly reduced the variability in plasma glucose, cholesterol, and cortisol, indicating that the stress of anesthesia with M.S. 222 is due to the low pK of the sulfonic acid moiety.read more

The Use of Clove Oil as an Anesthetic for Rainbow Trout and Its Effects on Swimming Performance
TL;DR: Clove oil was as effective as MS-222 in inducing anesthesia in both age-groups and exposure to either clove oil or MS- 222 at the concentrations tested was not detrimental to critical swimming speed of juvenile and adult rainbow trout Onchorhynchus mykiss.

Anaesthesia of farmed fish: implications for welfare.
TL;DR: The main objective of this paper is to review the knowledge of the effects of anaesthetic agents in farmed fish and their possible implications for welfare, and recommend that anaesthetic protocols should always be tested on a few fish under prevailing conditions in order to ensure an adequate depth of anaesthesia.
