Book Description
Hunters in 20 States of the Central and Mississippi flyways participated in an experiment 9-day teal hunting season in September 1965. During this special season, hunters were required to obtain a free permit and could shoot four teal a day (blue-winged teal, green-winged teal, and cinnamon teal (Spatula cyanoptera), singly or in the aggregate) and have eight in possession. Data were obtained by means of a mail questionnaire survey, a teal wing collection survey, and a hunter performance (spy-blind) survey. A total of 201,972 hunting permits was issued, 49,359 in the Central Flyway and 152,613 in the Mississippi Flyway. Of the applicants who obtained permit, 55 percent hunted. Hunters bagged 448,060 ducks, including 404,710 blue-winged teal and 39,610 green-winged teal. The harvest of illegal ducks, not recognized as such, was 3,600 (from the wing collection), but the actual illegal kill, based on the hunter performance survey, was estimated to be 33,736. The species most prevalent in the illegal kill were wood ducks (13,000) and mallards (7,088). Percentages of cripples and unretrieved ducks revealed by the hunter performance survey were added to these totals, which together with a projected kill for the regular season, gave a total hunting loss by species. These totals were converted to percentages of the fall populations and compared with proportions of the populations killed in previous years. These data suggest that the experimental teal season in 1965 provided 111,085 hunters 257,180 days of recreation without adversely affecting the continental population of and waterfowl species. Additional data are needed, perhaps from three special teal seasons, in order to establish whether the bagged ducks add to or reduce nonhunting mortality for the teal species involved.

Book Description
The 1956 catch of Atlantic menhaden (Breyoortia tyrannus) amounted to 766,000 tons. Apparent abundance, as measured by catch per purse-seine set, was highest in the North Atlantic Area and lowest in Chesapeake Bay. Geographical distribution of fishing effort is shown. Samples for age, size, and sex determinations were obtained from the purse-seine and pound-net catches landed from Fernandina Beach, Florida, to Portland, Maine. Age composition showed that the 1955 years class (age-1 fish) accounted for more than half of the total catch. This year class dominated the summer catches in the South Atlantic and Chesapeake Bay Areas as well as the fall catches in North Carolina, while the 1954 year class (age-2 fish) dominated in the Middle Atlantic Area, and the 1951 year class (age-5 fish) dominated in the North Atlantic Area. Fish of the dominant year class in each of these areas were smaller in 1956 than in the previous year.
