FISH FARMING TECHNOLOGY

Figure 7: In the back of the truck is a fish pump mounted to the right of the oxygen cylinder. Pumping fish onto the truck during loading is more efficient and safer than dipnetting or using a crane to move them.

Figure 10. Rough concrete floors, providing traction even when wet, can be created with a coarse broom when the newly-poured drying concrete is still wet.

Figure 8: The tops of the raceway walls at this federal facility are wider (14 inches wide) than the walls themselves (about 10 inches wide). This width is noticeably wider than the top of most raceway walls. The U.S. government’s Occupational Safety and Health Administration (OSHA) inspects this hatchery because it is a federal facility. Figure 9: Raceway walls can have a metal crosswalk bolted onto the top; the extra width is just at the top where the worker must walk, while the raceway wall itself is fairly narrow. This allows for a maximum amount of water for the fish and a minimum amount of cement to pour the wall (thereby conserving costs).

Figure 11: The red pipe on this feed bin extends up to the bin top allowing feed trucks to fill the bin from ground level. This intervention engineers the falling hazard out of this farm task.
