How Biological Activity in Sea Cucumbers Changes as a Function of Species and Tissue
Biological activity and bioactive compound content in sea cucumbers was assessed, considering Parastichopus regalis, Holothuria mammata, Holothuria forskali, and Holothuria arguinensis as species and intestine, muscle band, respiratory tree, body wall ...

In Situ Holothurian Noncontact Counting System: A General Framework for Holothurian Counting [PDF]
Holothurian counting is a basic requirement in aquaculture. An in situ noncontact approach for holothurian counting is basically harmless, which makes such techniques an optimal choice for aquaculture monitoring. To develop an in situ noncontact counting system, there are two main challenges.

Sea cucumbers reduce chromophoric dissolved organic matter in aquaculture tanks [PDF]
Background Mono-specific aquaculture effluents contain high concentrations of nutrients and organic matter, which affect negatively the water quality of the recipient ecosystems. A fundamental feature of water quality is its transparency. The fraction of
