The invention discloses a culture method for increasing the survival rate of young oysters, which comprises the following steps of: feeding 50 percent of chlorella, 20 percent of chrysophyceae, 15 percent of chaetoceros and 15 percent of platymonas in the early culture stage of the young oysters; the method comprises the following steps: feeding 30% of chlorella, 20% of chrysophyceae, 20% of chaetoceros and 30% of Platymonas subcordiformis at the later culture stage of the oyster seeds, managing the salinity, temperature and dissolved oxygen of an oyster seed culture water body, the culture density of the oyster seeds and the variety and matching proportion of biological baits, and improving the survival rate of the oyster seeds on the basis of original culture. The culture cost is reduced.

The present invention refers to a biomass of T. chuii and a pharmaceutical composition comprising a biomass of T. chuii for use in the treatment of infertility in a male subject. It also refers to a method for increasing the quality of the semen of a male subject having normozoospermia, not having hypospermia and not having a disorder characterized by a high percentage of sperm DNA fragmentation (SDF), that comprises the administration of a biomass of T. chuii.

The present application relates to the field of aquaculture breeding technology, and discloses an indoor cement pool artificial breeding method for east wind snail, which comprises the following steps: storing east wind snail egg sacs after disinfecting water body by ultraviolet rays, removing infected egg sacs, and performing specific water flow replacement 24 hours before hatching; feeding the larvae with a nutrient agent containing clostridium aceticum protein and agaricus blazei polysaccharide every day after hatching, feeding the larvae with monosomic algae such as chrysomonad, tetraselmis, chlorella, etc. in the early stage, and feeding the larvae with shelled algae in the middle stage until the larvae are attached and metamorphosed; keeping the breeding pool continuously aerated and controlling parameters such as dissolved oxygen, salinity, temperature and pH value of the water body during the breeding period, and finally collecting the snail seedlings to end the breeding. The indoor cement pool artificial breeding method for east wind snail provided by the present application is suitable for one or more of fasciolaria fasciolaris and mud east wind snail, and can effectively improve the success rate and seedling quality of indoor cement pool breeding of east wind snail.

The present invention relates to an aqueous red extract obtained from green algae belonging to the Tetraselmis genus, to compositions comprising same and to the use thereof, in particular as a dye.

The invention discloses a bacterium-alga co-immobilized material and application thereof in red tide treatment of prorocentrum donghaiense, and belongs to the field of microorganisms for harmful red tide treatment. According to the invention, alteromonas algicidal bacteria and autotrophic non-red-tide microalgae Tetraselmis are co-immobilized on the same carrier in an adsorption manner to form a bacteria-algae co-immobilized material. The bacterium-algae co-immobilization material has high algae-lysing performance on prorocentrum donghaiense red tide, the algae-lysing rate is 100% within 36 hours, and the algae-lysing rate is 84.07% after the bacterium-algae co-immobilization material is repeatedly used for four times. The bacteria-algae co-immobilized material has the characteristics of no toxicity, strong water absorption, high stability, reusability and the like, and can be effectively used for treating harmful algal blooms of red tide algae such as prorocentrum donghaiense.
