Optimal artificial conditions for keeping and breeding medicinal leeches Hirudo verbana and Hirudo orientalis
Aquaculture study published in Ann Parasitol (2025)
Abstract
The aim of the work is to obtain optimal artificial conditions for the maintenance and breeding of medicinal leeches of the species Hirudo verbana and Hirudo orientalis. 180 medicinal leeches were used in the study: 100 leeches of the H. verbana species and 80 H. orientalis leeches. Four groups of animals were formed: two control and two experimental. Control groups of medicinal leeches were kept using the standard jar method. Experiments according to the developed optimal scheme. As a result of the study, it was found that there were more juveniles obtained from the cocoon per 1 parent leech in the experimental group of medicinal leeches of the H. verbana and H. orientalis species, compared to the control group; appearance of defective cocoons. Mortality of parent leeches during breeding, mortality of juveniles before the first, after the first and sixth feeding decreases on average by more than 50% (P < 0.05) in the experimental group.

Resumen
Comparison of standard jar method versus optimized scheme for breeding H. verbana and H. orientalis. Optimized conditions reduce parent and juvenile leech mortality by more than 50%.
Por qué esto importa para la hirudoterapia
This study compared standard jar-method keeping of medicinal leeches (Hirudo verbana and Hirudo orientalis) against a newly developed optimal artificial maintenance and breeding scheme, using 180 leeches across four groups (two control, two experimental). The experimental groups yielded more juveniles per parent leech and showed reductions averaging over 50% in parent leech mortality during breeding and juvenile mortality before and after feedings compared to controls (P < 0.05). The abstract also reports findings regarding the appearance of defective cocoons, though the direction of this effect is not specified. The study addresses husbandry and breeding optimization for two medicinal leech species. Relevance to ASH's domain is indirect, as the abstract's scope is limited to keeping and breeding parameters.
