The term ``canning'' was defined in the legislative history of the
1949 amendments (House (Conference) Report No. 1453, 81st Cong., first
session; 95 Cong. Rec. 14878, 14932-33). These amendments made the
``canning'' of marine products or byproducts exempt from overtime only
under a separate exemption (section 13(b)(4), and subject to the minimum
wage requirements of the Act (see Sec. 784.136 et seq.). The same
meaning will be accorded to ``canning'' in section 13(a)(5) as in
section 13(b)(4) (see Sec. 784.142 et seq.) subject, of course, to the
limitations necessarily imposed by the context in which it is found. In
other words, although certain operations as described in Sec. 784.142 et
seq. qualify as canning, they are, nevertheless, not exempt under
section 13(a)(5) unless they are performed on marine products by
employees of the fishing vessel at sea as an incident to, or in
conjunction with the fishing operations of the vessel.
