A method and system for the inland aquaculture of marine species using water from a saline aquifer having a heavy metals content within the acceptable limits of the EPA guidelines for drinking water. The aquifer is preferably the Coconino aquifer located in Arizona and New Mexico. The system can be used to culture microalgae, macroalgae, fish, shrimp and many other marine species. Nutrients and fertilizers can be added to the water to optimize culture conditions for particular species. Useful products can be isolated from the marine species or the cultured marine species can be harvested as useful products themselves.

The device is a venturi-type narrowing (2) comprising outslip unit (11) being placed in front end of the narrowing, forming a part of the trawl. The outslip unit allows selection of marine species not to be caught. The fish to escape is directed towards the outslip unit (11).

The invention is an apparatus for the cultivation of marine species, particularly molluscan shellfish such as oysters. The shellfish are cultivated within a rotating cylinder featuring water-permeable walls, and positioned at the water surface by buoyant chambers such that a portion of the cylinder is immersed while the remainder is exposed to the atmosphere. The rotational position of the cylinder is advanced by way of a passive mechanical interaction driven by changes in local water elevations (e.g. tide cycles), thereby creating a repetitive and systematic exposure of the entirety of the cylinder wall to atmospheric desiccation. Furthermore, the rotation of the cylinder promotes a gentle tumbling of the shellfish within, thereby improving product shape and uniformity of growth, as well as enhancing the clearing of accumulating sediments and/or metabolic wastes.

The secondary species is stocked in an intensive closed or semi-closed system, while the tertiary species is stocked in a semi-intensive or closed extensive or semi-closed system. The multico system of the primary species is in communication with the system of the secondary species, while the system of the secondary species is in communication with the system of the tertiary species.

The invention relates to a system for treating ship ballast water for removing marine species and pathogenic bacteria from the ballast water, belonging to the application field of marine environmental protection technology. The system comprises a pipeline for discharging the ballast water in and out of a ballast tank of a ship, a seawater pump arranged on the pipe line for feeding and discharging water for the ballast tank, a coarse filter and a fine filter for sieving and filtering seawater, a detection instrument, a control system, an oxygen cabin, a nitrogen cabin and a gas-liquid mixing unit for rapid deoxidization and oxygenation. During the loading process, the ballast water is deoxidized by the gas-liquid mixing unit to limit oxygen content of the ballast tank, thus greatly lowering survival rate of aquatic organisms from the ballast water, avoiding formation of ferric oxide or rust, and reducing corrosion degree on the ballast water tank; and during the unloading process, the ballast water is oxygenated by the gas-liquid mixing unit to destroy anaerobic microbes in seawater, thus avoiding adverse effects of deoxygenated water on the local aquatic organisms.

The present invention relates to a seawater quality reference prediction method based on a quantitative structure-activity relationship of metal and metalloid. According to the method, the toxic endpoint of unknown metal is predicted according to a quantitative relationship between the structural feature of metallic ions and the marine life acute toxic effect, and a risk concentration for protecting different proportions of marine life is analyzed and deduced in conjunction with sensitivity distribution of different species; and a QSAR metal toxicity prediction model is established by integrating metal physical and chemical structure parameters and toxic mechanisms of different marine life and is applied to prediction of an unknown seawater quality reference maximum concentration. The seawater acute reference prediction method based on the metal quantitative structure-activity relationship is based on the ecology principle; the system screens various marine species and takes the screened marine species as smallest biological prediction sets; and single-parameter toxicity prediction models are established separately, thereby improving the model precision and prediction ability.

The present invention mimics the natural process of oceanic upwelling wherein deep ocean water rises into the photic zone and provides a nutrient rich environment for phytoplankton, the beginning of the marine food chain. The power of waves is utilized to cause a down-flow of warm surface water though a plurality of conduits. A heat exchange process delivers warmth to the deep water which rises in a conduit due to a buoyancy that results from the warming. Deep ocean water that is rich in nutrients is brought into the photic zone to facilitate the primary production of marine life. The present invention can convert a non-fertile ocean environment into a fertile ocean environment. This fertile ocean environment can be used for aquaculture and to restore and also to enhance marine populations. The present invention vertically mixes ocean water which has a multitude of other advantages.
