POLYMER IMPLANTS FOR TIMED RELEASE OF DRUGS WITH PARTICULAR EMPHASIS ON OVULATION OR SPERMIATION OF FISH

摘要

An improved cellulose acetate implant is able to more cost effectively provide ovulation of female fish. The time required for a production run of implants in CA is about 2-3 hours rather than days of the previous procedure. The method of generating the improved implant includes dissolving a hormone in water, adding acetone to the solution, adding cellulose acetate to the solution, mixing the solution, generating the CA/LHRH from the solution such as by extrusion and processing the CA/LHRH such as drying and cutting the CA/LHRH into strips of improved implants. Other polymers, substances and additives are also able to be used. The improved implants are then able to be inserted into fish at the proper time to increase ovulation which ultimately results in an increased number of fish.
