A study the effect of the broodstock density on reprodustive and culture of hirudinea manillensis (green leech)

Hirudinae Maniliens is also called as 'Buffalo leech' or Lintah Kerbau are distributed in several countries in Southeast Asia such as Southern China, Philippines, Thailand, Vietnam and Malaysia (Department of Fisheries Malaysia, 2009). In this study, effect of densities in culturing and re...
