Chorulon® provides the fish farmer with a tool to eliminate losses due to partial ovulation and
spawning, as well as to enhance egg quality, milt production, sperm volume and motility, and
resulting fertilization rates. In comparison with the traditionally used crude fish pituitaries,
Chorulon® has several further significant advantages which have become increasingly important in
today's modern and intensive fish farming industry:
Chorulon® is the only hormonal spawning aid approved by the FDA in the USA for use in finfish (NADA no. 140-927). It is a freeze-dried preparation of human chorionic gonadotrophin (hCG) for administration after reconstitution in the accompanying sterile diluent. It has luteinizing hormone (GtH-II)-like activity with little or no follicle stimulating hormone (GtH-I) or oestrogenic activity.
|Species like carp can benefit greatly from the use of Chorulon®|
After reconstitution, Chorulon® is administered via intramuscular injection just ventral to the dorsal fin for one to three injections. Any single injection should be administered, depending on the fish species, at a dose of 110 to 1120 I.U./kg body weight (bw) for males and 150 to 4000 I.U./kg bw for females.
The Intervet Aquatic Animal Health Newsletter 4 (March 2002) contains more information on Chorulon for Fish.
