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 §§ 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).
