Filtration Rates of Catfish Pond Phytoplankton by Nile Tilapia Oreochromis niloticus
Filter-feeding fishes have been examined as biological controls of phytoplankton populations. Although increased phytoplankton biomass resulted in approximately 50% of studies and no effect in 25% (Smith 1988), changes in species composition and dominance have been noted. For example, blue tilapia Oreochromis aureus reduce or eliminated blue-green (Cyanobacteria) and green (Chlorophyta) net phy...
متن کاملHydrogen production. Green algae as a source of energy.
Hydrogen gas is thought to be the ideal fuel for a world in which air pollution has been alleviated, global warming has been arrested, and the environment has been protected in an economically sustainable manner. Hydrogen and electricity could team to provide attractive options in transportation and power generation. Interconversion between these two forms of energy suggests on-site utilization...
متن کاملPhotosynthetic Hydrogen and Oxygen Production by Green Algae
Photosynthesis research at Oak Ridge National Laboratory is focused on hydrogen and oxygen production by green algae in the context of its potential as a renewable fuel and chemical feed stock. Beginning with its discovery by Gaffron and Rubin in 1942, motivated by curiosity-driven laboratory research, studies were initiated in the early 1970s that focused on photosynthetic hydrogen production ...
متن کاملOptimizing Triploid Walleye Production in Colorado
Walleye (Sander vitreus) provide important recreational and commercial fisheries throughout the United States and Canada. In Colorado, more walleye are stocked every year than any other species of fish. Use of sterile triploid fish in Colorado is an important management strategy for protecting native endangered fish species from naturally reproducing populations of introduced predators like wal...
متن کاملDelayed Light Production by Blue-green Algae, Red Algae, and Purple Bacteria
1. Blue-green algae, red algae, and purple bacteria all show the emission of delayed light. 2. The action spectra for the production of delayed light by three species of blue-green algae have one broad band with a peak at 620 mmicro. 3. The action spectrum for production of delayed light by the red algae has one peak at 550 mmicro with a shoulder from 600 to 660 mmicro. 4. The emission spectra ...
