Length frequency - equations used to estimate standard lengths and weight

The available data on the sizes of shark species caught by the different fisheries are presented as: 
Size frequency data available: The size frequency data available in the IOTC databases is presented in the following xls file (compressed with WinZip):
• FL_SKH.zip (as of 15-07-2013) , contains the available data for blue shark (BSH), bigeye thresher shark (BTH), silky shark (FAL), oceanic whitetip shark (OCS), porbeagle (POR), crocodile shark (PSK), and shortfin mako (SMA)
All size data strata not recorded as standard length (fork length for sharks) was converted into standard length by using the equations available for each species. Fish recorded under size class intervals other than those used for billfish species was assigned to the corresponding  size class interval(s) for each species (first class is 15cm for all billfish species and class interval is 3cm).

Equations: The equations used to estimate standard lengths from non-standard measurements and to estimate weight from the available lengths can be found in Equations.doc (as of 01-07-2013)
Details about the type of SF data available can be found in SF_Reference.xls (compressed with WinZip).
