Porcine circovirus-2 (PCV-2) is a recently identified agent wherein the potential spectrum of PCV-2-associated disease has been expanded by evidence of vertical and sexual transmission and associated reproductive failure in swine populations. PCV-2 was isolated from a litter of aborted piglets from a farm experiencing late term abortions and stillbirths. Severe, diffuse myocarditis was present in one piglet associated with extensive immunohistochemical staining for PCV-2 antigen. Variable amounts of PCV-2 antigen were also present in liver, lung and kidney of multiple fetuses. Inoculation of female pigs with a composition including an immunogen from PCV-2 or an epitope of interest from such an immunogen or with a vector expressing such an immunogen or epitope of interest prior to breeding, such as within the first five weeks of life, or prior to the perinatal period, or repeatedly over a lifetime, or during pregnancy, such as between the 6th and 8th and/or the 10th and 13th weeks of gestation, can prevent myocarditis, abortion and intrauterine infection associated with porcine circovirus-2. In addition, innoculation of male and/or female pigs with the aforementioned compositions can be carried out to prevent transmission of PCV-2 from male to female (or vice versa) during mating. Thus, the invention involves methods and compositions for preventing myocarditis, abortion and intrauterine infection associated with porcine circovirus-2.

A high efficiency recirculating marine aquaculture process for producing fish at variable yield densities of up to 60 kg/meter3 of the aquaculture tank, including fish that spawn under short photoperiods such as gilthead seabream (Sparus aurata) as well as fish that spawn under long photoperiods such as striped bass (Morone saxatilis).

An innovative optical system and method is disclosed for analyzing and uniquely identifying high-order refractive indices samples in a diverse population of nearly identical samples. The system and method are particularly suitable for ultra-fine materials having similar color, shape and features which are difficult to identify through conventional chemical, physical, electrical or optical methods due to a lack of distinguishing features. The invention discloses a uniquely configured optical system which employs polarized sample light passing through a full wave compensation plate, a linear polarizer analyzer and a quarter wave retardation plate for producing vivid color bi-refringence pattern images which uniquely identify high-order refractive indices samples in a diverse population of nearly visually identical samples. The resultant patterns display very subtle differences between species which are frequently indiscernable by conventional microscopy methods. When these images are analyzed with a trainable with a statistical learning model, such as a soft-margin support vector machine with a Gaussian RBF kernel, good discrimination is obtained on a feature set extracted from Gabor wavelet transforms and color distribution angles of each image. By constraining the Gabor center frequencies to be low, the resulting system can attain classification accuracy in excess of 90% for vertically oriented images, and in excess of 80% for randomly oriented images.

An autonomous open-ocean fish-farming structure has a submersible cage enclosure tethered to a topside buoy.

The self-positioning, self-powered fish-farming structure enables unmanned, extended marine deployment in deeper ocean waters without the need for tethering or anchoring to the ocean floor. Multiple structures can be maintained in a spaced apart configuration to comprise a flotilla of fish farming structures attended by a tender ship that is autonomous, easily serviced and conveniently relocated.

A liquid birdfeeder includes a generally upstanding container having a large opening at its top end and a bottleneck opening at its lower end. A quarter-turn removable cap is screw-threaded onto the top end to seal the top end opening. The lower bottleneck opening is screw-threaded into a central collar of a feeding basin having a plurality of feeding ports. An actuator rod extends longitudinally through the container and is operatively connected to a biased sealing mechanism which selectively seals or opens the bottleneck opening. When the removable cap is screw-threaded onto the top end opening, the cap depresses the actuator rod causing the biased sealing mechanism to move to an open position which allows liquid to flow out from the container into the feeding basin. When the removable cap is removed, the actuator rod can move upwardly under the force of the biased sealing mechanism, which moves the sealing mechanism to a closed position and prevents liquid in the container from flowing into the feeding basin. The container can then be filled through the top opening without flooding the feeding basin. In one preferred embodiment, the bird feeder includes a common functional feeding module connected within an outer decorative cladding by an interference fit.

A tank agitator connects to a low head feed and causes agitation by discharging through a port that might rotate, oscillate, or otherwise issue a pulsing stream. This agitator has a housing with a turbine plenum and an exhaust plenum. A turbine in the turbine plenum spins by the flowthrough of the feedwater and exhausts to the exhaust plenum. A hollow drive shaft is spun by the turbine and extends through the exhaust plenum and to terminate outside the housing. It has an aperture that allows water in the exhaust plenum to flow into its lumen. A nozzle caps the shaft and is bent such that the discharge issuing therefrom sweeps in circles with the spinning of the drive shaft. A variant form of the agitator includes a drive train that incorporates a drag link to convert the spinning input of the turbine into an oscillating output in the drive shaft. In another variant form, the discharge is pulsed. To do this, the exhaust plenum lies between an opening to the turbine plenum and a port in the housing wall to the outside. A blocker door is coupled to and driven by the spinning turbine to cycle between uncovering and covering one of the exhaust opening and the discharge port. Given the foregoing, the discharge stream issuing from the discharge port will pulse between alternating phases of flow and quiescence.

A scalable fish rearing raceway system is provided, incorporating a fish containment structure having two semi-circular end sections, and two or more parallel fish raceways, surrounding a central zone for housing water treatment systems and a secondary fish crop. Heavy particulates are eliminated from the main fish rearing channels by use of conical areas located at either end of the parallel elongated raceways. Continuous removal of dead or dying fish from the raceway is accomplished by means of a floating mortality catcher consisting of a screened ramp at the surface of the cones which continuously collect moribund and dead fish. Grading bars separate and move fish underwater to an adjacent raceway through a common fish transfer channel. This larger scalable fish production system substantially reduces the direct labor and capital costs associated with the production of fish as compared with conventional circular fish rearing tanks. Continuous removal of dead fish from the raceway is accomplished by means of a sinking fish mortality catcher consisting of a screened ramp at the entrance to the hydrocones which collect both moribund (sunken) and “long” dead (floating) fish. A similar device is mounted at the main drain box on the outside of the raceway to capture dead and floating fish. The continuous removal of dead and dying fish significantly reduces labor costs associated with the frequent manual removal of such fish and reduces the transmittal of infectious diseases by the immediate removal of the dead and dying fish.

A system and method for providing access to animal food utilizes identification tags on domestic animals, generally attached to a collar. The identification tag generates a signal that is detected by a receiver mounted on an enclosed food container. When the receiver detects a pre-selected acceptable signal from an animal, it activates a motor that causes a movable portion of the container to move to an open position. If the signal is no longer detected by the receiver, it activates the motor to move the movable portion of the container to a closed position. If the receiver detects a signal from an identification tag that is not one of the pre-selected signals, it activates the motor to move the movable portion of the container to a closed position.
