The 1960 input composition for Florida constitutes the index base. Utilizing the fishing power indices to create a standardized mea- sure of fishing effort in the GMRFF has significant implications in relation to both stock assessment and management questions. A compari- son of fishing effort measured in nominal terms (vessels) and fishing effort measured in standardized terms (standardized vessels) is pre- sented in Table 4. The standardization of vessels results in substantial
