The system can include a spawning platform which includes a porous or perforated element that allows the embryos but not the aquatic animal to pass through and a separator which includes a porous or perforated element that can be used to separate the male aquatic animals from the female aquatic animals during a priming phase. In operation, the spawning platform can be placed in the bottom of the tank in order to provide a bottom collection area where the embryos can be collected and the aquatic animals cannot eat or otherwise harm the embryos. The female aquatic animals can be placed in tank above the spawning platform.

Abstract: The application is directed to an aquatic egg collection research system. The egg collection includes stepped racks that hold a plurality of tanks in a stepped configuration. A stepped fluid conduit assembly and stepped drain respectively supply water to the tanks and collect water flowing out from the tanks. A barrier partitions the tanks enabling eggs to fall through but prevents the adult fish from scavenging the eggs. Nets are placed by a user in strategic areas for trapping eggs from the water flowing out from the tanks. In some embodiments, the tanks are totally opaque, internally lighted, and have an electronic timer for controlling the internal lighting in the tanks. The eggs can be studied with various microscopic slides customized for the research.

Abstract: 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.

Adjacent segregated pools are attached to each other with a vertical separation, and upper segregated pools are smaller than adjacent lower segregated pools. Each segregated pool has a gate. The inter-pool transporter is mounted detachably between the gates of adjacent segregated pools and has two end sides corresponding respectively to the gates of adjacent segregated pools.

Abstract: 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). The process involves broodstock conditioning, spawning/reproduction, larval growth, nursery, and adult grow-out operations. The process is characterized by high-rate growth at optimal process conditions requiring less than 10% daily water exchange, thereby enabling effluent waste from the system to be discharged to a municipal sewer after disinfection treatment, which in turn permits siting of the aquaculture process facility in urban/suburban locations where aquaculture processes have been previously infeasible.

Abstract: The present invention provides a compact culture system to produce microalgae, live food animals and fish fry (new born fish) in a serial manner. The culture system is composed of three individual reactors of same size positioned in different levels on three shelves of a frame. In the top-level reactor, microalgae is grown symbiotically with fish. With so grown microalgae, live food animals in the middle-level reactor are fed. Finely, the live food animals are transferred into the bottom-level reactor to feed fry in it. Culture water in the system is self-cleaned by the metabolic activity of the photosynthetic microalgae, and is circulated through the reactors continuously or intermittently. Heaters, thermometers, aerators, illuminators, and water pumps are equipped in the system to offer optimal growth conditions for the organisms. Extra electric outlets are provided for the use of pH-meters, oxygen-meters, carbon dioxide-meters, ammonia-meters when needed to control the water quality.
