Use of medicinal plants to enhance the breeding and microbiological quality of the flesh in the snail <i>Cryptomphalus aspersus</i>

Abstract

The interest in snail farming to help with food security has increased significantly in recent years, but this industry still confronts several difficulties, notably in achieving high-yield and quality production. This study investigates whether medicinal plants can improve reproduction and reduce mortality and bacterial sepsis in the snail Cryptomphalus aspersus (Müller, 1774) gathered in Morocco and fed on various diets. Over seven months, two stages were conducted: observing snail growth and characteristics, then tracking reproduction. Medicinal plants Rosmarinus officinalis L (Labiatae), Origanum compactum, and Thymus zygis subsp. gracilis (Boiss)R were employed. Results showed these plants significantly lowered death rates, improved reproduction parameters, and reduced bacteria in snail flesh, including the eradication of Escherichia coli and sulphate-reducing bacteria. This study underscores the potential of using medicinal plants as feed supplements, enhancing Cryptomphalus aspersus snail farming sustainability and quality.
