Trends in the lake trout fishery of Lake Huron through 1946

The production of lake trout, Cristivomer namaycush (Walbaum), in the United States waters of Lake Huron was highest in the earliest years for which there are statistical records, averaging 2,362,000 pounds in 1879–1894. The general level of yield was much lower but relatively stable in 1895–1939, during which period the catch averaged 1,685,000 pounds. The most recent years have seen a rapid and

Vitamin A and carotene contents of some wildlife foods

In order to determine possible sources of vitamin A for quail, 37 species of insects and other invertebrates were analyzed for vitamin A and for carotene, and 26 species of seeds and fruits were assayed for carotene. The invertebrates showed no trace of vitamin A; but 8 herbivorous invertebrates and the praying mantis contained carotene. Most of the plants contained carotene--some of them a lot (d

Vitamin A storage in wild quail and its possible significance

Livers of 445 wild bobwhites taken in Iowa, Wisconsin, and Illinois in late fall and winter of 1947-48 were assayed for vitamin A. All contained vitamin A; but the amount in many was so low that it is estimated that 4% of the birds would have died directly from lack of vitamin A within 3 weeks or that as much as 42% might have been affected enough to make them die from predation and severe weathe
