This invention provides a vessel system and methodology that can be used to promote growth of phytoplankton in the oceans. Unmanned self-controlled wave-powered vessels are equipped with storage units for dispensing a fertilizer, and with sensors to monitor ocean conditions and effects. Fleets of vessels move autonomously by on-board processing of GPS and directional information, piloting a path that is coordinated by a central processing unit. The vessels travel through a defined target area, creating a detailed survey of chemical and biological characteristics that affect grown. The data are processed in a computer model to identify precise locations and precise amounts of fertilizer that will produce the best results. Projected benefits of fertilizing plankton include sequestering CO2 from the atmosphere, and enhancing the marine food chain to improve the fish stock in and around the treated area.

Areal population density and detailed behavior of fish schools and their interaction are continuously monitored over continental-shelf-scale areas spanning thousands of square kilometers by ocean acoustic-waveguide remote sensing. In some embodiments, the capacity of certain geophysical environments, such as continental shelves, islands, etc. to behave as acoustic waveguides is utilized; sound propagates over long ranges via trapped modes that suffer only cylindrical spreading loss, rather than the spherical loss suffered in conventional sonar approaches.

The invention discloses a wind-power fish food thrower. The wind-power fish food thrower comprises a feeding box, wherein an upright plate is fixedly arranged on the upper end face of the feeding box,a rotating chamber is formed in the upright plate, a starting mechanism is arranged in the rotating chamber, a working chamber is formed in the feeding box, a feed throwing mechanism is arranged in the working chamber and comprises a first rotating shaft which is rotatably arranged on the lower end wall of the working chamber, a transmission chamber is formed in the feeding box, a vertical grooveis formed in the rear end wall of the transmission chamber, and a transmission mechanism is arranged in the transmission chamber. According to the wind-power fish food thrower, fish food can be thrown into a sea by the device through wind power as long as the fish food is placed in a food storage box, so that manpower consumption is effectively lowered; and through wind-power feeding, the fish food can be better thrown into a fish pond even if the area of the fish pond is relatively large, and thus, fish stocks in the fish pond can relatively uniformly share the fish food.

The invention relates to a method for classification and identification of fish eggs and larval and juvenile fishes, and is characterized in that firstly, adult fish samples in an investigated water area are collected and are classified and identified, DNA is extracted from various classified and identified fish samples, COI sequences are amplified and sequenced by PCR respectively, and accordingly, a COI sequence database of the investigated water area fishes is established; then investigated and collected fish egg and larval and juvenile fish samples are numbered, and the COI sequences are amplified and sequenced by using the same method; the sequencing result is compared and analyzed with the established COI sequence database, and thus the types of the fish eggs and the larval and juvenile fishes are identified. The fish eggs and the larval and juvenile fishes at the fish early developmental stage are classified and identified fast, the shortages of difficult identification of fish eggs and larval and juvenile fishes, long time consuming and large workload are overcome, and fast, accurate and efficient advantages are showed.

Eicosapentaenoic acid (EPA) compositions and EPA-rich polar lipids for prophylactic or therapeutic applications are described. Production from certain cultured micro-organisms (like Nitzschia laevis) promotes synthesis of EPA, including polar lipids including EPA. The EPA-rich polar lipids themselves may be used as polar compounds. EPA can be selectively hydrolysed from particular positions in isolated polar lipids by lipase activity, then optionally further purified. The process bypasses reliance on diminishing fish stocks and on physico-chemical processes that may not adequately separate desirable n-3 HUFAs from unwanted products like DHA also found in fish oil and cultured organisms.

The invention discloses a treatment method for a water ecosystem of a eutrophic water body. The treatment method comprises the following steps: 1) removal of fishes; 2) addition of a silicate composite aqueous solution; 3) planting of a variety of emergent aquatic plants in a target water area; 4) planting of a variety of floating-leaved plants in the target water area; 5) construction of a submerged plant community in the target water area; 6) fish population structure preliminary construction engineering: a step of stocking fish species for controlling algae and trash fishes in the target water area; 7) selection of benthonic animals for the target water area, wherein the benthonic animals are manually put on the water surface of the target water area; 8) putting of herbivorous control fishes to realize basic control of the submerged plants; and 9) putting of siniperca chuatsi and / or culter alburnus. The treatment method provided by the invention has small investment, fast action andlong-acting working basis, does not pollute the environment, is environmentally friendly, can be used for a long time, is wide in application range, can be applied to ponds, lakes, landscape water bodies, reservoirs and the like, and is not limited by water areas.
