CATDOLL : CATDOLL: How to choose to use fish oxytocin?

1. How to choose and use fish oxytocin?

Commonly used oxytocin hormones include: carp and crucian carp pituitary gland (PG), human chorionic gonadotropin (HCG), luteinizing hormone releasing hormone analogue (LRH-A), dioestrogen (DOM), reserpine (RES), etc.

2. Reasonable use of fish oxytocin?

The drugs currently used to induce spawning using dried fish include: the commonly used fish ovulation induction No. 2 (LHRH-A2), fish chorionic gonadotropin (polysexual hormone, HCG), chorionic gonadotropin type A, chorionic gonadotropin type B, fish ovulation induction No. 3 (LHRH-A3), diometron (DOM), fish pituitary gland (pituitary gland, PG) and a variety of complex high-efficiency oxytocin, but the most commonly used ones are fish ovulation induction No. 2 (LHRH-A2) and fish chorionic gonadotropin (polysexual hormone, HCG).

For fish with low spawning rate and low total spawning volume, such as loach, Chinese spiny target (Qingbo) and other medium and high-end fish, dioic acid (DOM) and pituitary gland (PG) should be added on the basis of using LHRH-A2+HCG, and the effect will be doubled.

For common fish, such as grass carp, silver carp, bighead carp, carp, crucian carp, etc., LHRH-A2+HCG is effective, and there is no need to add other oxytocin drugs to reduce production costs. Grass carp using LHRH-A2 alone, silver carp using chorionic gonadotropin type A alone, and bighead carp using chorionic gonadotropin type B alone are sufficient to achieve the purpose of smooth spawning.

3. What are the commonly used fish oxytocins?

Commonly used fish oxytocin agents include the following: 1. Oxygen: Oxygen is a hormone-based oxytocin agent, which is often used to increase the spawning rate of female fish and promote the maturation of follicles. Common oxytocin agents include synthetic GnRH (growth hormone-releasing hormone), hCG (human chorionic gonadotropin), etc. 2. Clonidine: Clonidine is an anesthetic, which is often used in the process of fish oxytocin. It can inhibit the physiological response of fish, reduce the stress response during spawning, and increase the spawning rate. 3. Ovaprim: Ovaprim is a commercial oxytocin agent made of a mixture of GnRH and hCG. It is often used in artificial breeding of marine fish and can effectively promote follicle maturation and spawning. 4. Acacetin: Acacetin is a plant extract with an oxytocin effect. It is often used in artificial breeding of freshwater fish and can increase the spawning rate of female fish and promote the maturation of follicles. It should be noted that the use of fish oxytocin agents should comply with relevant laws, regulations and technical specifications to avoid adverse effects on the environment and fish. At the same time, the use of oxytocin requires strict adherence to the instructions to ensure the effectiveness of oxytocin and the health and safety of the fish.
