of law,” and (2) whether the appellant is exempt from the terms of the Endangered Species Act because on the Act’s effective date, December 28, 1973, the animals seized by the agents were held in captivity for a proper purpose under the Act.
Appellant’s constitutional argument appears to be that the Endangered Species Act has deprived him of the use of his property in that his animals were seized and he is subjected to criminal prosecution for his attempted sale of them. We hold that the statute does not effect an unconstitutional taking of property within the meaning of the Fifth Amendment because the statute does not prevent all sales of endangered wildlife, but only those sales in interstate or foreign commerce. The Act does not purport to control intrastate transactions involving protected wildlife, and presumably appellant could have sold the animals in the State of Florida. In addition, 16 U.S.C. § 1539 allows the transportation or sale of endangered wildlife if the Secretary of the Interior approves it “for scientific purposes or to enhance the propagation or survival of the affected species.” Accordingly, we determine that the Endangered Species Act of 1973 permissibly regulates the transportation or sale of protected wildlife and does not effect a taking of property in violation of the Fifth Amendment. Goldblatt v. Town of Hempstead, 369 U.S. 590, 82 S.Ct. 987, 8 L.Ed.2d 130 (1962).
With respect to appellant’s contention that he held the animals on December 28, 1973, for a proper purpose under the Act, we observe that the exemption upon which he relies “shall not apply in the case of any fish or wildlife held in the course of a commercial activity.” 16 U.S.C. § 1538(b) (emphasis added). The district judge instructed the jury that it could not convict unless it found that defendant’s transportation of the animals was in the course of a commercial activity. There was substantial evidence from which the jury could properly conclude that defendant’s transportation of the animals was in the course of a commercial activity.
Accordingly, the judgment of conviction on Count Two will be affirmed.
