Subject: Mangrove Crab (Scylla serrata) Fisheries- Recruitment

Dear All,

I am looking for information on the natural recruitment of Scylla serrata 
into a trpical fishery (Tanzanian coast).  Are there any ways in which to 
calculate the levels of recruitment from stock assessment data ?  Or are 
there any models which can be applied to the fishery (possibly based on 
shelter ??) and if so what data is required ?  Any help would be 
gratefully recieved 

Thanks

Stuart Priestley

Stuart,

What kind of data can you collect from the fishery?  It would seem
that if you can obtain length frequency data over at least one year,
you could possibly apply the ELEFAN program of ICLARM to estimate
periods of recruitment, yield per recruit, etc.  I am not aware of
ELEFAN being applied to crabs, but it has been applied to cockles in
Malaysia, so it should work with Scylla serrata.
