Cucumaria in Russian Waters of the Barents Sea: Biological Aspects and Aquaculture Potential
Sea cucumbers are a popular luxury and delicacy food items in Asian markets. These echinoderms possess a wide range of bioactive substances that can be used to produce pharmaceutical products. Recent depletion of natural populations of sea cucumbers requires involving new objects both in commercial...
