Neurolipofuscin Is A Measure Of Age In The Caribbean Spiny Lobster, Panulirus Argus, In Florida, Kerry Elizabeth Maxwell
Biology Theses
Accurate age estimates for the commercially-important Caribbean spiny lobster, Panulirus argus, would greatly enhance analyses of life history and population dynamics. Previous estimates of their age based on size and growth may be inaccurate because of variable growth in the wild. An established technique for aging crustaceans – histologically-determined lipofuscin content in the nervous system – was used on lobsters reared in the laboratory for up to five years. We verified the presence of lipofuscin in eyestalk neural tissue and described its distribution in cell cluster A of the hemiellipsoid body. Neurolipofuscin content of both sexes increased linearly over the …
Growth And Population Assessment Of Spotted Bass (Micropterus Punctulatus) In Beaver, Table Rock, And Bull Shoals Lakes, Northern Arkansas-Southern Missouri, Jeremy Troy Risley
Growth And Population Assessment Of Spotted Bass (Micropterus Punctulatus) In Beaver, Table Rock, And Bull Shoals Lakes, Northern Arkansas-Southern Missouri, Jeremy Troy Risley
MSU Graduate Theses
Little research has been conducted on spotted bass, Micropterus punctulatus, even though it is a popular recreational fish. Most previous research was on young-of-the-year fish and interactions among other species in reservoirs, with little research on adult spotted base in the Ozarks region or other regions of the United States. The objective of this study was to compare the growth and population characteristics of spotted bass within and among Beaver, Bull Shoals and Table Rock Lacks. Growth, abundance, and conditions within and among reservoirs were similar. However, spotted bass in Beaver Lake did not reach as great lengths as those …
