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.

The invention discloses a high-efficiency treatment method of ballast water in a ship and a device adopting the high-efficiency treatment method. The high-efficiency treatment method of ballast water in a ship comprises the following steps of 1, removing planktonts and suspended particles in ballast water by a high-efficiency filter, wherein the removed planktonts and the suspended particles have sizes of above 30 to 40 micrometers; 2, based on a branch electrolysis-based inactivation treatment technology, electrolyzing a part of seawater passing through an electrolysis unit into chlorine and hydrogen by the electrolysis unit, wherein the chlorine is fast dissolved in seawater to form sodium hypochlorite, and 3, feeding back the high-concentration sodium hypochlorite solution obtained by the step 2 to a ballast water feeding header pipe so that residual harmful aquatic organisms in the ballast water are killed. The high-efficiency treatment method of ballast water in a ship has the advantages that a technology of high efficiency filtration and branch electrolysis-based inactivation treatment and the equipment suitable for the technology are adopted; a technical flow is simple; a system volume is small; compared with the existing system, the device adopting the high-efficiency treatment method has a floor space reduced by above 30%; because of the utilization of branch electrolysis, a hydrogen generation amount is low so that hydrogen can be removed completely; a potential safety hazard is eliminated; installation is convenient; and safety and reliability are high.

The invention relates to aquaculture biological fish manure, in particular to novel high-efficiency biological fish manure for various aquacultures. The fish manure is prepared from the following raw materials in parts by weight: 17.5 to 70 parts of ammonium chloride, 10 to 40 parts of monoammonium phosphate, 7.5 to 30 parts of calcium superphosphate, 12 to 48 parts of organic matters, 0.5 to 2 parts of bacillus, and 2.5 to 10 parts of humic acid. The fish manure is prepared by selecting more than twenty types of major and trace element inorganic fertilizers with comprehensive nutrition and organic fertilizers which can be easily absorbed, is rich in more than twenty types of major and trace elements and various amino acids, vitamins, polysaccharide, nucleic acids, humic acid and the like, and is fermented by 81 beneficial microorganisms in five major groups of microorganisms existing in the whole ecosystem. The fermented free-state nutritional substances are advantageous to absorption and utilization, so that the nutrition balance of a water body is ensured. By application, a small ecological environment is formed, so the biological fish manure is particularly suitable for growing and breeding of plankton which facilitates aquaculture.

An aquatic particle sampling and collection apparatus comprising a tube within a tube cylindrical collection system wherein an inner tube is housed within an outer tube wherein the outer tube has a front end that is flared in a frustum shape to collect water. The inner tube defines an open chamber lined with a net or other collection apparatus which concludes with a conical cod end. An axial flow pump is situated within the collection system to facilitate the movement of water through the system thereby drawing particles in to be collected. The apparatus is paired with a subsea vehicle that allows for controlled collection and sampling. In various embodiments, the apparatus can be used to collect both bio particles such as plankton and non-bio particles such as plastics from the ocean. Where sampling is desired, the apparatus may include a disk after the conical cod end upon which the samples are collected.

A method of ecological restoration of water bodies containing excess nutrient includes steps of: (a) taming a kind of plankton to be able to eat blue algae as an algae eating plankton, so as to digest blue algae in the water bodies, and (b) putting the algae eating plankton in the water body polluted by the blue algae, wherein the algae eating plankton eats the blue algae, so that an eco-system of the water body containing excess nutrient can be restored.

The invention discloses a fresh water shrimp culture method, which comprises the steps of weed culture, shrimp postlarvae selection, stocking time selection, and control during shrimp postlarvae culture. The step of control during the shrimp postlarvae culture comprises the steps of: controlling waterweed coverage rate and water body transparency: when the fresh water shrimp culture is in the medium term, particularly fresh water shrimps enter autumn-propagation season (August and September in Yangtze river basin), the waterweed area is controlled to be 40 to 50 percent of the water body area, the transparency is controlled to more than 40 centimeters, and shrimp postlarvae is difficult to survive due to insufficient plankton bait; and killing the autumn-propagation shrimp postlarvae by skillfully using quick lime: during culture, the growth and development condition of the shrimps is frequently observed, particularly when the fresh water shrimps enter the autumn-propagation season (August and September in Yangtze river basin), the egg hatching condition of precocious female is observed, and when eggs of most ovigerous female become grey or transparent or zoea is hatched out, 10 to 14g of quick lime is used for each cubic meter of water body, the quick lime is sprayed to all the pond in six days, and afterwards the quick lime is used once each week to kill the autumn-propagation shrimp postlarvae. The technical measure can reduce 70 to 90 percent of autumn-propagation shrimp postlarvae.

The invention relates to a penaeus vannamei boone low-salinity culturing method. During seed culturing, the salinity is 8 to 100%; in the phase of juvenile shrimps, the salinity of a culturing water body is increased to 6%; in the phase of middle-age shrimps, the salinity of the culturing water body is reduced to 4%; in the phase of adult shrimps, the salinity of the culturing water body is reduced to 2%. The method has the advantages that the secondary virus disease caused by the infection of pathogen of penaeus vannamei boone in seawater is avoided, meanwhile, the growth speed of the penaeus vannamei boone is ensured, and the economic benefit of a farmer is protected; by utilizing the habits of Chinese soft shell turtles, silver carps or bighead carps using planktons as foods, the amount of seaweed in water is controlled, so the water quality is improved, the waste at water body resources is avoided, and better economic benefits can be obtained.
