(3) Historical account of fishery resources and habitats and analysis.— A historical account of the fishery resources and fishery habitats of the basin and an analysis of the current status and the trends of such resources and habitats, including an analysis of the existing and projected problems facing such resources and habitats. (4) Evaluation of information.— An evaluation of the adequacy of the information that is currently available, and specification of the additional kinds and quantity of information that must be obtained, for purposes of carrying out the conservation and restoration of the fishery resources and the fishery habitats of the basin.
