Section 13(b)(4) provides an exemption from the overtime but not
from the minimum wage provisions of the Act for ``any employee employed
in the canning, processing, marketing, freezing, curing, storing,
packing for shipment, or distributing'' aquatic forms of animal and
vegetable life or any byproducts thereof. Orginally, all these
operations were contained in the exemption provided by section 13(a)(5)
but, as a result of amendments, first ``canning'', in 1949, and then the
other operations in 1961, were transferred to section 13(b)(4). (See the
discussion in Secs. 784.102 to 784.105.) These activities are ``shore''
activities and in general have to do with the movement of the perishable
aquatic products to a nonperishable state or to points of consumption
(S. Rept. 145, 87th Cong., first session, p. 33).
