 Subject: Marphysa sanguinea life history

 Over the last eight years I have witnessed heavy harvesting pressure
 of Marphysa sanguinea in local bays for use as fishing bait.

 I would like to find out if the harvesting of Marphysa sanguinea in
 local bays is sustainable.

 I would appreciate receiving general information on the life history
 and ecology of this species.

 Some of the questions I am seeking answers for are:

 What is the longevity of Marphysa sanguinea?

 How old it is when it first breeds and how many years does it breed

 How long do the larvae stay in the water column before settling to
 the sea bed and how widely dispersed can they be before settling to
 the bottom.

 I wish to know whether transplanting of this species from nearby
 areas has been tried to repopulate a shore?

 I have a photograph of the species here:

Large numbers of individuals are dug up in our local bays:

 Our specimens grow to a length of about 60 cm:

 I have searched the Internet and found a few abstracts but I do not
 have a local library available to provide me with any journals.

 Thank you for the help you can provide.

 Best wishes,
