1. A raceway for shrimp production, comprising:
a sloped base with an apex,
a divider extending upward from the apex,
two side walls, each opposing and parallel to the divider sufficient to form two elongated channels on the sloped base; and
at least two tapered ends in fluid communication with the channels, each tapered end configured as a recovery zone and comprising:
an end wall,
a pit,
a sloped floor extending from the sloped base to the end wall or pit
and arranged between the sloped base and the pit such that the sloped floor has a downward slope of an angle of 1 to 45 degrees relative to a vertical reference towards one or more of the end walls and is in contact with the tapered ends to increase a cross-sectional area of the channel; wherein the sloped floor meets the sloped base at a first point at the two side walls and at a second point at the apex and the first point is closer to the end wall than the second point;
the end walls including an inlet where a pump supplies fluid to the raceway, the inlet being provided in-line with an outlet channel;
the sloped base having an angle of about 6 degrees to about 8 degrees relative to the horizontal axis; and
a collection zone located in the pit, the collection zone comprising one or more openings, and
a filter or screen in the one or more openings for the collection of molts.
