This book was released on 2007 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Only 6% of spawners originated from rivers other than the York, supporting the hypothesis that most American shad spawn in their natal river. Of remaining spawners, 79% originated from the Mattaponi River and 21% from the Pamunkey River. The results suggested that while most American shad home to their natal river there is less fidelity to individual tributaries, allowing subsidies to subpopulations with persistent recruitment failure. Otolith signatures were also used in mixed-stock analyses of immature migrants along the coast of Maine in the spring and Minas Basin in the summer. Mixed-stock compositions showed remarkably low diversity and were dominated by fish from the Shubenacadie and Hudson rivers, with an increasing proportion of Potomac River fish over time. In contrast to results from adult tagging studies, southern stocks were virtually absent. These data suggest ontogenetic shifts in migratory behavior. The thesis concludes with a report that water contributed 83% of Sr and 98% of Ba in the otoliths of a marine fish.

This book was released on 1961 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted to determine the effect of abrupt temperature and salinity changes on adult and juvenile striped bass (Roccus saxatilis) and American shad (Alosa sapidissima). Transfers were made at specific temperature and salinity differences over the range 45° to 80° F. and 0 to 35°/00. Adult and juvenile striped bass were tolerant to transfers between salt and fresh water at most temperature differences. Adult shad were tolerant to transfers from fresh to salt water and displayed some tolerance to transfers from salt to fresh water at limited temperature differences. Juvenile shad survived salinity and temperature differences from salt to fresh water, but did not survive these differences from fresh to salt water.
