The invention is directed to kits, compositions, tools and methods for biologically cemented structures. More particularly, the invention is directed to materials and methods for the farming of bivalves, such as oysters and clams, and also other marine and fresh water invertebrates such as sponges, and other commercially worthwhile sessile organisms. The kits, compositions, tools and methods of the invention are also applied to erosion control of beaches and underwater surfaces, for the formation of foundations such as footings for pier supports, marine walls and other desirable structures.

A netting conduit. The conduit defines a continuous channel extending between a first open end and a second open end. The conduit is fabricated from netting having a mesh size sufficient to prevent most fish from traversing through the netting material. The conduit tapers from the first open end to a midsection and enlarges from the midsection to the second open end. The longitudinal edges of the conduit can define a parabolic shape. The conduit further includes stakes that are usable to anchor the conduit to the bed of the waterway in which the conduit is in use.

A securing clip includes: an enclosure body including a first end, a second end, and one or more sidewalls that extend between the first end and the second end; one or more fragment module securing tangs extending, from one or more of the sidewalls, into the cavity such that when at least a portion of the fragment module is placed within the cavity, at least a portion of the fragment module securing tang is designed to engage with the fragment module and prevents and/or impedes removal of at least a portion of the fragment module from the cavity; and one or more substrate securing tangs extending from the enclosure body and away from the cavity, each substrate securing tang designed to prevent and/or impede removal of the securing clip when the securing clip is placed into a substrate aperture defined within the substrate.

A method for controlling the gate based on the habitat requirement for fish overwintering in rivers. According to the characteristics of biological habitat of the river and the habitat demand of fishes during overwintering, the method specifically comprises the steps of: firstly, determining candidate fishes for ecological flow calculation though fish resources investigating and historical data, and then screening out the target fish by adopting hierarchical analysis method; Secondly, establishing a quantitative response relationship curve between target fish physiological adaptions and water temperature, obtaining ecological water level which ensures the target fish overwintering safely according to the vertical temperature distribution, and establishing the relation between water depth and discharge using hydrodynamic model; finally, setting up a gate control system including a radar water level meter in the overwintering areas and an ecological water level management system in a gate control room.

A water intake and pretreatment system (10) comprising an inlet for delivering water from a natural source to a reservoir (12); said inlet to reservoir having a net screen (16) to prevent entry of organisms above a predetermined size and including a one-way gate (30) to allow organisms to exit the reservoir; said reservoir further comprising a granular filter media for water and algae filtration; and a drainage layer for removal of filtered water from the granular filter media to a drainage outlet. A local backwashing apparatus (40) is included for localized backwashing of the granular filter media.

Systems and methods for cultivating or accumulating climate-focused marine target products are described herein. The target product may be microalgae, macroalgae, plankton, marine bacteria or archaea, filter feeders (such as oysters or clams), or crustaceans either for the purpose of bioremediation, eventual cultivation or for sequestering carbon dioxide; or the target product may be direct chemical or biological accumulation of carbon or carbon containing organisms. The system is primarily a floating apparatus designed to hold the target product in a region of the water column and in a spatial region of the water where it will best accumulate target product mass. In some embodiments the system is designed to achieve eventual passive sinking (transformation from a floating to sinking apparatus) into the deep ocean. In some embodiments, the system is equipped with purpose-chosen sensors to instrument and quantify the various biological and mechanical processes occurring onboard.

A floating ecosystem for deployment in a body of water, the ecosystem comprising a number of elongate members which are arranged side-by-side and define one or more corresponding elongate planting lanes between them. These planting lanes allow for the insertion and support of plants at predetermined lateral separations. The elongate members are advantageously resilient and closely spaced so as to provide structural support to plants inserted in the planting lanes. The ecosystem may also comprise a material or component which is partially biodegradable and partially durable and/or non-biodegradable; the biodegradable portion initially provides natural planting media for improved plant establishment then makes way for root spread and plant growth as it decays
