Book excerpt: Obviously, the number of eggs that could be taken by spawn-takers for hatchery purposes at any one time has generally been accepted as the total number of eggs a shad could be produced in a season. Since only a part of the eggs are ripe and ready for spawning at one time, these earlier records represent but a fraction of the number of ova actually produced during a spawning season.

This book was released on 1957 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the American shad (Alosa sapidissima) in Chesapeake Bay was made in 1952. Catch and effort records were combined with data obtained from tagging studies conducted at the entrance to Chesapeake Bay, in the James and Potomac Rivers, and at Cove Point (Maryland) to obtain population parameters for these areas. These studies were successful except for the results of tagging at the mouth of the Bay, which data could not be used because of a disproportionate tag recovery-catch ratio between the various areas of Chesapeake Bay. Total population and escapement were determined for each year in which data were available. It is recommended that the States of Maryland and Virginia establish comparable systems for the collection of catch-and-effort records on the shad so that these basic data will be available for any future study of the Chesapeake Bay fisheries.

Download or read book Fisheries Research in the Hudson River written by C. Lavett Smith and published by SUNY Press. This book was released on 1988-01-01 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses specific water quality and pollution problems and documents the changes that occurred during the critical transition period when PCB dumping was discontinued and water treatment plants came into increased use. It will appeal to fishery biologists working with Atlantic coast species, people involved with estuaries worldwide, and to all environmentalists interested in the history of the landmark Hudson River Settlement Agreement. The signing of the Hudson River Settlement Agreement ended more than a dozen years of controversial court battles over the placement of electric generating plants on the Hudson River estuary. Much of this agreement was based on original field research, the most compelling of which is found in this book. Fisheries Research in the Hudson River includes a summary of existing fisheries data bases, with comments on their strengths and weaknesses and a guide to their availability, as well as discussions of the natural history of striped bass, white perch, river herrings, tomcod, sturgeon, and a very important food source, the amphipod gammarus tigrinus. It also proposes a management plan for sturgeon, a plan based on an age-structured population model that demonstrates the practical application of basic scientific data.

Download or read book Ova Production of American Shad in Atlantic Coast Rivers written by William S. Davis and published by . This book was released on 1957 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of ova produced by American shad (Alosa sapidissima) based on samples of five fish from each of six Atlantic coast rivers was found to range from 209,000 to 616,000 ova per year. Hudson River shad produced fewer ova by size and St. Johns River shad produced more ova by size than did shad from the other four rivers. Statistical evidence is presented to show that the six ovarian samples per fish used to estimate total ova production can be reduced without imparing the accuracy of the total ova production estimate.
