Population Dynamics Of Young-Of-The-Year Striped Bass, Morone Saxatilis, Populations, Based On Daily Otolith Increments, Lisa L. Kline Jan 1990

Population Dynamics Of Young-Of-The-Year Striped Bass, Morone Saxatilis, Populations, Based On Daily Otolith Increments, Lisa L. Kline

Dissertations, Theses, and Masters Projects

Validation of daily increment deposition in otoliths of juvenile striped bass up to 80 days of age was provided through sequential sacrifice of known age hatchery-reared fish in 1987 and 1989, and through tetracycline marking of otoliths of cage-cultured striped bass in 1989. Ages of fish between 80-110 days old were consistently underestimated by 1-3 growth increments. Known age juvenile striped bass were raised in the laboratory in 1989 under controlled environmental conditions. These experiments provided evidence of an endogenous circadian rhythm controlling daily increment deposition in juvenile striped bass otoliths. Juvenile striped bass were collected in the 4 Virginia …


Comparative Community Structure Of Surf-Zone Fishes In The Chesapeake Bight And Southern Brazil, Cassiano Monteiro-Neto Jan 1990

Comparative Community Structure Of Surf-Zone Fishes In The Chesapeake Bight And Southern Brazil, Cassiano Monteiro-Neto

Dissertations, Theses, and Masters Projects

The structure of surf-zone fish communities at Cassino (western South Atlantic, WSA) and the Chesapeake Bight (western North Atlantic, WNA) is described using historical beach seine data, to examine similarities between geographically isolated fish communities. Numerical classification, ANCOVA, Shanon-Wiener diversity and its components, and species rarefaction are used to describe fish community structure: (a) within habitat (Cassino); (b) within region (Chesapeake Bight); (c) within the western Atlantic (comparison between Cassino and the Chesapeake Bight). The surf-zone fish community at Cassino had a low diversity and was dominated by a few species. Seasonal periods identified by cluster analysis correlated well with …
