The invention discloses an artificial selecting-breeding method of antibacterial-disease good varieties of bostrichthys sinensis. The artificial selecting-breeding method includes the specific steps that survival fish fingerling entities after bacterial diseases are collected in high disease-affecting season; chorionic gonadotropin and luteinizing hormone-releasing hormone are injected into female fishes before parent fishes lay eggs, and chorionic gonadotropin is injected into male fishes; fertilized eggs are incubated at the temperature of 20 DEG C to 30 DEG C, and the antibacterial-disease good varieties of the bostrichthys sinensis are obtained. The artificial selecting-breeding method has the advantages that the survival fish fingerling entities after bacterial diseases in high disease-affecting season are selected as the parent fishes, and the antibacterial-disease capacity is high; the problem that fry of the bostrichthys sinensis are short is solved, large-scale breeding of the fry of the bostrichthys sinensis is achieved, the requirements of farmers for artificial fry of the bostrichthys sinensis are met, and the artificial selecting-breeding method is suitable for application and popularization of bostrichthys-sinensis breeding farms in national coastal areas, and has the large development market space.

Method for breeding or odontobutis obscurus

The invention discloses a method for breeding odontobutis obscurus. The method comprises the following steps: firstly, performing parent breeding of the odontobutis obscurus with freshwater shrimp and pseudorasbora parva as baits; secondly, selecting mixture of chorionic gonadotropin, an luteinizing hormone-releasing hormone analogue and maleic acid European ketone as an oxytocic, matching female odontobutis obscurus with male odontobutis obscurus according to the ratio of 1:1.2 and placing the matched odontobutis obscurus into a spawning pond; thirdly, controlling the water temperature for spawning at 19-21DEG C, placing (n+2) spawning nests in the spawning pond, wherein n is the number of the female odontobutis obscurus; fourthly, after spawning, taking meshes to which fish roes are attached from the spawning nests, lapping the meshes on PVC (Polyvinyl Chloride) incubating tubes, enabling each mesh to correspond to one air stone, and transferring the meshes to an incubating frame for continuously incubating in two days before the fish roes break through membranes until incubating fries; fifthly, continuously culturing for one week with living food of daphnia pulex larvae and moina as initial feed. According to the method disclosed by the invention, the fertilization rate, the hatching rate and fry survival rate of the odontobutis obscurus are improved.

Rapid propagation method for mud fish

The invention discloses a rapid propagation method for mud fish. The method comprises the following steps of (1) selecting the mud fish which are two to three-winter-old, 15 to 20cm in body length and 30 to 50 grams in body weight as propagation parents, and ensuring that the female/male ratio of the parent mud fish is 1:2-1:3; (2) taking the parent mud fish out of a culture pond, putting the parent mud fish on a spawning induction bed, and injecting 800 to 1,000 international units of chorionic gonadotropin to each parent female mud fish and 400 to 500 international units of chorionic gonadotropin to each parent male mud fish by adopting an intramuscular injection method; (3) putting the parent mud fish subjected to spawning induction into an incubation jar for spawning, taking the parent mud fish in a net of the incubation jar out after 20 hours of spawning, ensuring that eggs are independently incubated in the incubation jar, continuously injecting new clear water in the incubation process to ensure that water in the incubation jar flows; (4) after incubating for 1 month, making sure that fries of the mud fish in the length of 2.5-3.6cm are formed. According to the method, the propagation time of the mud fish is greatly shortened, the hatching rate is improved, the manpower is reduced, and the aquaculture economic benefit is improved.

Control of infectious microorganisms by modulation of chorionic gonadotropin-related protein activity

A method of controlling, in a warm-blooded animal, an infectious microorganism expressing a chorionic gonadotropin-like growth-regulating protein comprises modulating the activity of the protein by administering to the warm-blooded animal an effective amount of an antibody capable of inhibiting the activity of the protein, the chorionic gonadotropin-like growth-regulating protein itself such that the animal develops a neutralizing immune response, or peptides that block the receptors of the chorionic gonadotropin-like growth-regulating protein in the infectious microorganism. Candida albicans is one such microorganism that can be controlled by delivering an antibody against the growth-regulating protein, CaCGLP. Mycobacteria can also be controlled by this method. A method of inhibiting transition of Candida albicans blastospores in vitro by contacting the blastospores with an antibody against CaCGLP is also disclosed. A method of inhibiting growth of mycobacteria in vitro comprises contacting the mycobacteria with an antibody against an endogenous chorionic gonadotropin-like growth-regulating protein. In vitro growth of microorganisms can also be stimulated by contacting the microorganism with a chorionic gonadotropin-like growth-regulating protein.
