The present application belongs to the technical field of gene editing, and particularly relates to a gene editing method for obtaining a bivalve adult editing body. Specifically, a target gene with an outward visible phenotype and an early development not lethal is taken as a marker, target sites sgRNAs are designed based on the marker, and then a Cas9 / sgRNAs editing body is constructed by means of an electrotransfection system, so that gene editing of the bivalve is realized and the adult editing body is obtained. The present application breaks through the technical bottleneck that the existing gene editing of the bivalve is limited to the larva development stage and the editing body is difficult to screen in adulthood, and provides a new technical system for creating the editing body germplasm of the bivalve. In addition to being applicable to oysters, the technical system is also applicable to other bivalves with small fertilized eggs, difficult microinjection and high larva culture mortality.

Systems and methods are providing for filtering a body of water, such as a lake, ocean, river or the like. A system comprises a housing having an interior configured for containing a plurality of bivalves within the water and a fluid distribution system coupled to the housing and configured to circulate water within the interior of the housing such that the water is filtered by the bivalves at a rate of about 10 to about 100 gallons of water per day per bivalves. The system provides a controlled environment to allow bivalves, such as clams, oysters and scallops, to filter the water naturally and remove materials, such as sediment, nitrogen, phosphorus, carbon, magnesium, zinc and the like. Oysters may, for example, filter pollutants from the water, remove excess nitrogen from the water and / or remove carbon from the water, which reduces the overall amount of carbon that eventually ends up in the atmosphere.
