Potential Spawning Strategy And Fecundity Of Alabama Shad (Alosa Alabamae) From The Apalachicola River, Florida, Hannah Grice, Lauren Patterson, Celeste Giangiacomo, Morgan Bowen, Bill Davin

Georgia Journal of Science

Alabama shad (Alosa alabamae), classified as a Species of Concern by the National Marine Fisheries Service, are native to the northern Gulf of Mexico drainages. Our study estimated the fecundity of 39 female Alabama shad from the Apalachicola River, Florida. Individuals ranged in age from 2-4 years with an average weight of 729 g. Samples (1 g) were cut from the center of each ovary, and oocytes present were counted. Diameters of 50 randomly-sampled oocytes were measured per sample. Oocyte diameters ranged from 0.3-2.7 mm, with a mode of 1.5 mm. The unimodal oocyte diameter percent frequency distribution suggests that …

Population Size And Passage Efficiency Of Alabama Shad Reaching Jim Woodruff Lock And Dam, Patrick Ely

All Theses

In this study, I estimated the population size of migrating Alabama shad below Jim Woodruff Lock and Dam (JWLD) in the Apalachicola River located in the central panhandle of Northwest Florida using mark recapture and relative abundance techniques. The number of marked fish was adjusted for tag loss, emigration and mortality. The population size of migrating Alabama shad near JWLD was estimated at 26,029 (95% C.I. = 15,174 - 49,040) in 2005 and as 972 (95% C.I. = 270 - 9,720) in 2006. Due to the small sample size, a relative abundance method was used to independently estimate a population …
