The Reproductive Cycle And Larval Tolerances Of Rangia Cuneata In The James River, Virginia, Thomas David Cain
The Reproductive Cycle And Larval Tolerances Of Rangia Cuneata In The James River, Virginia, Thomas David Cain
Dissertations, Theses, and Masters Projects
The autecology of the brackish water clam Rangia cuneata was investigated in the James River, Virginia, from February 1970 to January 1972. The reproductive cycle, combined salinity and temperature effects on embryos and larvae, and setting were studied. Histological slides were made, set collected, and temperature and salinity measurements taken from three populations living in different salinity regimes. Phases of gonad development are described. Gametogenesis started in April and from May through September clams were found in all gonadal phases. Ripe gonads were found from May to late November with no summer or inactive period. It was determined by the …

Feasibility Of Artificial Propagation And Introduction Of Hybrids Of The Morone Complex Into Estuarine Environments, With A Meristic And Morphometric Description Of The Hybrids, Jerome Howard Kerby
Feasibility Of Artificial Propagation And Introduction Of Hybrids Of The Morone Complex Into Estuarine Environments, With A Meristic And Morphometric Description Of The Hybrids, Jerome Howard Kerby
Dissertations, Theses, and Masters Projects
Laboratory and environmental studies of striped bass (Morone saxatilis) X white perch (M. americana) and striped bass X white bass (M. chrysops) were used to-determine the feasibility of introducing these hybrids into an estuary as a supplement to natural populations of the parental species. Growth patterns, survival, and general hardiness of the hybrids were used as criteria. Growth of striped bass X white perch hybrids in the laboratory was apparently somewhat less than growth of natural populations of striped bass, but was much greater than growth of natural populations of white perch. Hybrid growth was slower than striped bass growth …
