Abstract: An artificial propagation method of Sinocyclocheilus rhinocerous, comprising placing female and male parent fish in a sterilized culture container in which a black cave simulant is placed in advance, strictly controlling the environmental parameters of the parent fish culture. The method realizes natural spawning and sperm production of S. rhinocerous under artificial conditions without using oxytocin. There is no oxytocin used in the artificial propagation, thus not only obtaining a higher fertilization rate and incubating rate, but also reducing the aquaculture cost. The operation is simpler and faster. At the same time, different feeds are fed in different growth stages according to the different growth characteristics of each stage of S. rhinocerous fry, thereby increasing the survival rate and reducing the deformity rate of fries. Therefore, the method provided by the present disclosure realizes efficient artificial propagation method of S. rhinocerous.

Abstract: An ocean powered Rankine cycle turbine includes a loop in which is circulated a working fluid. A first heat exchanger effects a phase change of the working fluid from liquid to gas. The gas expands to power a turbine. Gas exiting the turbine is condensed by a second heat exchanger to effect a phase change from gas back to liquid. A piston assembly is used to compress air. A wave energy converter uses ocean wave energy to reciprocally move the piston. As the wave goes down, the piston is extends drawing air into the piston housing. As the wave goes up, the piston compresses the air. Heat generated as the piston compresses air, is used to as a heat source for the first heat exchanger. Cold compressed air is used as a cold source for the second heat exchanger.

Abstract: A heat exchanger comprising a plurality of plates that are demountably attached to a frame is disclosed. Each plate comprises a plurality of channels for conveying a primary fluid through the heat exchanger. The frames are arranged in the frame so that spaces between adjacent frame pairs define conduits for conveying a secondary fluid through the heat exchanger. The plates are mounted in the frame so that they can be individually removed from the frame. Further, each of the channels is fluidically connected to input and output ports for the primary fluid by detachable couplings. As a result, heat exchangers in accordance with the present invention are more easily repaired or refurbished than prior-art heat exchangers.

Abstract: Feeding method and production technology of a vegetarian feed for carnivorous fish prepared from Spirulina and Chlorella algae that are produced by cell proliferation in production tanks in electrolyzed water with chlorine-neutralizing sodium thiosulfate and are subsequently dried, pelleted and packaged. The fish feed can be employed without the fish having diarrhea. As a result, the water in fish breeding tanks does not become immoderately eutrophic and at the same time the daily weight gain of the fish is not affected. An optimum daily growth rate and a fish flesh quality can be achieved without the use of animal and fish-based proteins in the fish food ration. The fish food is also inexpensive and ecologically sustainable and ethically acceptable, since it contributes to the rescue of the remaining fish stocks in waters worldwide.

Abstract: A tidal irrigation and electrical system used to harness the power of the ocean tide to generate electricity, create sustainable aquaculture, act as a CO2 sink, and generate hydrocarbons. An artificial atoll is created on the continental shelf to define a lagoon completely isolated from the surrounding ocean. As the tides rise and fall, the natural tidal action draws nutrient-rich, cold seawater into the lagoon to stimulate the growth of biolife. As the ocean tide falls, the natural tidal action draws the lagoon water out of the lagoon and through a biofilter to remove the biolife prior to discharge of the water back to the ocean.
