AB A comparison of the anaesthetic effect on eels (Anguilla anguilla) between the commercially available eugenol (4-allyl-2-methoxyphenole or 2-methoxy-4-propylphenole respectively; "Aqui-S") and the chemically similar structured antioxidants BHA (2-tert.-butyl-4-methoxyphenole) and BHT (2.6-di-tert.-butyl-p-cresole) showed, that BHA exerted the strongest effect. Eugenol ("Aqui-S") and BHA are both useful for breakdown of stress during transportation or keeping in tanks of eels, but not suitable for industrial stunning/slaughtering of eels. Desliming process of eels was optimal, when a special mixing and rotating machine (tumbler construction or mixer principle) with the following parameters were used: addition of 3% of a saturated chalk milk solution (Ca(OH)2), 10% soda or 0.3% ammonia solution (ratio of alkaline solutions: eels = 3 : 97); 10 rpm; desliming 10 minutes. The use of the desliming agent chalk milk has ecological and econimical advantages. The desliming loss was between 5 and 6%.
