99.5% Pure Tricaine Methanesulfonate

FDA Approved for Aquaculture

FINQUEL MS-222 is the most widely used and trusted anesthetic for aquatic animal use in aquaculture, fishery and veterinary settings.

The FINQUEL brand sets the standard for quality, safety and potency backed by Argent's twenty-five years of manufacturing experience with the chemical synthesis of Tricaine Methanesulfonate.

FINQUEL MS-222 is a fine white powder packaged in amber glass bottles of 5 grams administered by bath or spray to induce sedation or anesthesia.

Since 1987, more than ten thousand FINQUEL MS-222 product units have been FDA approved and distributed around the world.

The wide ranging popularity of FINQUEL MS-222 can be attributed to its quality, availability and ease of use: Aquatic animals readily absorb it across the gill tissue, the degree of sedation or anesthesia is easily varied for a wide variety of applications, and animals recover rapidly after exposure and resume normal physiological and behavioral functions.

FINQUEL MS-222 is used for a multitude of beneficial applications ranging from the spawning of genetically selected rainbow trout or prize winning ornamental Koi, to the collection of marine reef fish, and the protection of endangered Pacific salmon.

Other widely accepted and safe uses include sedation or anesthesia of aquatic species for trans-shipment, sorting and grading of farmed fish, sampling of captive and native populations, biological and physiological research, surgery, and health examination.

FINQUEL is intended for the temporary immobilization of fish, amphibians, and other aquatic, cold-blooded animals. It has long been recognized as a valuable tool for the proper handling of these animals during manual spawning (fish stripping), weighing, measuring, marking, surgical operations, transport, photography, and research.

DIRECTIONS FOR USE ON FISH CONCENTRATIONS

FINQUEL is effective and safe for the anesthesia of fish when used as directed. Its use is governed by, and can be tailored to, the needs of individual fishery personnel. Sedation and various rates of anesthetization are controlled by the concentration. The versatility of FINQUEL is demonstrated by the fact that it has been used in fisheries at levels ranging from 10 to 1,000 mg./liter. The action of the anesthetic is slowed at cooler temperatures, in extremely soft water (approximately 10 mg./liter of CaCO3. or less), and in larger fish. Also, efficacy may vary with species. Thus, it is imperative that preliminary tests of anesthetic solution be made against small numbers of fish to determine the desired rates of anesthesia and exposure times for the specific lots of fish under prevailing conditions.

METHODS OF APPLICATION

1. General anesthesia: - For most situations where rapid or moderately rapid anesthesia is required, FINQUEL may be applied in a bath, i.e., the fish are immersed in the anesthetic solution. Containers may be of glass, plastic, steel, aluminum, or other suitable material. However, do not use galvanized or brass containers unlless treated or sealed to prevent dissolution of zinc. Size of container is determined by individual needs, but the fish should not be overcrowded. Discard anesthetic solutions when a loss in potency is noted, or when the solutions become fouled with mucus or excrement.

2. For surgery and certain physiologic studies, the fish may be anesthetized to loss of reflex, removed from the anesthetic, and then positioned so that the gills are bathed in a sedating concentration of FINQUEL. Some investigations have developed flowing, recirculating systems for bathing the gills with anesthetic during surgery.

Large fishes such as sharks and rays are anesthetized within minutes by spraying the gills with a 1 g./liter solution of FINQUEL. The application is made by means of a water pistol, bulb syringe, hand pump, etc.

3. Transport - FINQUEL has been used to sedate fish during transport. It is more successful in cold than in warm water, and it is instrumental in reducing injuries because of hyperactivity. Fish are usually transported by means of distribution units (tank trucks), or by air in plastic bags. In either case, the fish should be fasted before-hand to reduce metabolic wastes. Aslo, some workers suggest pretransport sedation for several hours to lower metabolism. With distribution units, the fish may be fasted and sedated prior to loading. The anesthetic solution is prepared in the distribution unit and oxygenated. Then, the fish are added and temperature acclimated.
