Growth And Survival Of Larval Fishes: The Role Of Zooplankton Abundance And Competition, Michael T. Welker
Growth And Survival Of Larval Fishes: The Role Of Zooplankton Abundance And Competition, Michael T. Welker
Masters Theses
Interactions among larval gizzard shad, bluegill and zooplankton prey were examined via a controlled mesocosm experiment and field sampling in Lake Shelbyville, Illinois. In the mesocosm experiment gizzard shad growth and survival were negatively correlated with shad density and positively correlated with macrozooplankton prey. Bluegill growth was also positively correlated with prey availability, but survival was uniformly high despite differences in zooplankton abundance and fish density. Declines in macrozooplankton and copepod biomass were related to fish density. In Lake Shelbyville limnetic overlap of larval gizzard shad and bluegill was limited to a three week period, with the interval of greatest …
The Effect Of Nutrition On The Morphology Of The Wool Follicle, Gail Moriarty
The Effect Of Nutrition On The Morphology Of The Wool Follicle, Gail Moriarty
Theses : Honours
This project was part of a larger CSIRO experiment which was examining the factors involved in the development of tender wool. In order to understand the effect of nutritional variations on wool quality, changes in cellular activity and morphology within the wool follicle were examined. Six sheep with a history of producing low staple strength wool (< 25 N/ktex) and six sheep with a history of producing high staple strength wool (> 30 N/ktex) were selected. The experiment ran for 18 weeks, for the first 10 weeks the sheep were fed a restricted ration to achieve a weight loss of approximately 175g/day. From weeks 11 to 18, the sheep were fed an iso-energetic ration containing …
