Spawning Chronology Of Native And Introduced Striped Bass (Morone Saxatilis) In Two Gulf Of Mexico Drainages, Matthew Noad
All Theses
In this study, I investigated the potential for temperature to serve as a mechanism for maintenance of reproductive isolation in a sympatric population of Atlantic and Gulf striped bass in the Apalachicola and Ochlockonee rivers, Florida. Adult striped bass (n= 66, mean weight = 8.3 kg, mean total length = 780.6 mm) were collected from February to May below Jim Woodruff Lock and Dam, on the Apalachicola River, and below Jackson Bluff Lock on the Ochlockonee River, Florida. Ancestry (Gulf or Atlantic) of specimens was determined based upon the methods of Wirgin et al. (2005) using three diagnostic microsatellite loci: …
Age, Growth, And Fecundity Of Alabama Shad (Alosa Alabamae) In The Apalachicola River, Florida , Travis Ingram
Age, Growth, And Fecundity Of Alabama Shad (Alosa Alabamae) In The Apalachicola River, Florida , Travis Ingram
All Theses
Age and growth of Alabama shad Alosa Alabamae were estimated by examining scales and otoliths from 203 adult fish collected on their spawning run in the upper Apalachicola River from 2005 and 2006. Ages of Alabama shad ranged from 1 - 4 years. Scales and otoliths both gave similar age estimates. Age distributions from this study differed from those of previous studies for both males and females. Female Alabama shad, on average, were found to be larger than males at age 2 and age 3. Alabama shad demonstrated a positive correlation of length to fecundity, with fecundity estimates ranging from …
Population Size And Passage Efficiency Of Alabama Shad Reaching Jim Woodruff Lock And Dam, Patrick Ely
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 …
