摘要： An apparatus and method for rearing shrimp through the larvae stage wherein the shrimp are subjected to controlled conditions and a common enclosure for the male and female adult shrimp is provided which permits uncontrolled access of the shrimp to one another and wherein the shrimp are maintained through a plurality of cycles of mating, spawning and hatching. The system is further provided with filtration means for filtering the medium of the common enclosure and with collecting means for collecting hatched shrimp at preselected times from the common enclosure medium as the medium moves into the filtration means.

摘要： A method and apparatus for rearing aquatic animals wherein the animals are retained for an initial period of growth in a first rearing means including a first habitat means comprising a first plurality of stacked substrates having a first combined total surface area and wherein the animals are retained for at least one subsequent period of growth in at least one further rearing means including a second habitat means comprising a second pulrality of stacked substrates having a second combined total surface area greater than the aforesaid first combined total surface area. The habitat means of each rearing means are adapted to be inserted within or removed from the medium of such rearing means, depending on whether it is desired to rear crustaceans or fish, or both, in polyculture. In further aspects of the invention, unique filtration means for continuously filtering the rearing medium and culling means for transferring or harvesting the animals are also disclosed.

摘要： A centrifugal separating apparatus having a vessel with a chamber assembly disposed therein that is rotated by a rotatable main shaft driven by a motor at a predetermined speed for separating water and oil from a stream of fluid. The rotatable chamber assembly defines an upper chamber for receiving the stream of fluid from an inlet tube and a lower chamber for collecting water separated from the stream of fluid. The upper chamber is in fluid flow communication with a plurality of U-tube assemblies with each assembly having a pair of upper oil separation tubes and a single lower water separation tube that extends outwardly in a radial direction from the chamber assembly at the near end of each U-tube assembly. The free end of each U-tube assembly is engaged and communicates with one of a plurality of tubular return sections that collectively define an outer tube that allows for the separation of the oil and water from the stream of fluid during rotation of the main shaft by the centrifugal separating apparatus. A strain retaining plate is engaged to the chamber assembly and the outer tube for providing structural support such that centripetal forces applied by rotation of the main shaft does not apply excess stress to the U-tube assemblies. The motor is in operative association with a microprocessor controller that terminates operation of the apparatus when vibrations generated by the operation of the apparatus exceeds a predetermined value.
