CONTROL OF REMEDIA LIFE PLANT IN APRIL 2019: SPONGES

The sponges located since last September, although less photogenic than the nearby sabellid worms are in good health. The monitoring carried out showed a survival of the bred fragments close to 90%. The initial phase that is the most critical and delicate seems to be overcome, in fact, the surfaces are well healed and it is already possible to observe their growth.

The breeding of porifers in the natural environment is carried out by exploiting their ability to reproduce asexually by fragmentation. In September, “donor” specimens were collected in immersion, taking care to leave the basal part of the individual on site to allow it to regrow. The collected specimens were cut into fragments and positioned inside mobile structures (retinas of the type used for mussel farming and / or suspended on lines). We will soon proceed with the replacement of mobile structures to prevent the spring recruitment of fouling covering and suffocating sponges, preventing them from filtering and growing.
