Shrimp feeds are among the most expensive diets within the aquaculture industry, largely due to their need for high water stability. Shrimp locate feed exclusively by smell and taste rather than sight. Unlike finfish, shrimp require minutes or hours to locate feed after it is distributed in ponds.

The extrusion process begins with preconditioning the meal using steam and water to form a hot, moistened mash. The mash is introduced into the extruder barrel and conveyed to the other end by a rotating screw which creates heat due to friction. The feed exits the extruder barrel through a restricted die opening that creates pressure and forms the desired shape. The extrudate strands emerging from the die are cut into pellets with a rotating knife. The process has flexibility to produce diets with a wide range of fat levels, densities, shapes and sizes.

Sterlets, carp, tench and rudd are just a few of the fish species that we class as bottom-feeding fish since they prefer to eat food from the depths of the pond that they inhabit. Sinking pellet food is specifically designed to accommodate these fish and therefore generally dense in its formulation so that it does not float on the water's surface.

Sinking pellet fish food is a fast-sinking highly digestible food that considers the natural eating habits and unique dietary requirements of fish species that prefer to feed on lower levels of the pond.

The highest quality, most premium pond foods tend to be in pellet form. Sinking pellets don't blow away in the wind like flakes and tend to pack more actual food per volume, making them popular with pond keepers who need to feed a lot to keep their fish growing.
