The steelhead trout used to be a native species to the Arroyo Del Valle in Pleasanton, California. Some are anadromous fish (i.e. they spend most of their time in freshwater developing after they hatch and then spend part of their later life in the sea or ocean) but others will remain in a freshwater stream or creek their entire lives. Typically, anadromous populations swim up the creek in winter to lay their eggs and then swim back, leaving the eggs to develop on their own. In order to lay…

to plants in the optimum 5.5 to 7.0 range, making the difference in the pH not effective to plants. These Ph levels also have no effect on the fish, but if the levels were under 4.5 Young fish and aquatic insects at an immature stage of their life could die from extreme sensitivity to a lower level pH levels. However, if the pH levels were between 9-14 fish can be harmed…

in 1954 to counteract the drastic drop in native fish stocks caused by overfishing (Lowe 2000). ¨They originally comprised 80% of the total fish biomass in Lake Victoria, but have now decreased to less than 1% offish catches from the Kenyan waters of the lake¨ (Lowe 2000). A 2003 study in the journal Nature examined algae records from the bottom of Lake Tanganyika and found that over the last century, warming waters have driven down the lake’s fish yield by 30 percent (Achieng 2006). ¨The flesh…

parasitic copepod that infects the gills of freshwater fish and is most easily visible once they mature and move into the fish’s mouth. For those that haven’t seen them, mature adults resemble a small white dot (less than 1/8”) with what look like legs. Those ‘legs’ are actually the egg sacs of the female parasite which are in the last stage of their life cycle. Despite being unattractive, there is little cause for alarm. These parasites have not directly caused a fish kill in the waters where…

support the Dwarf Wedge Mussel habitat. What regulations or measures could be taken in the Tuckahoe system to create an environment in which the Dwarf Wedge Mussel could potentially be introduced and protected? The Dwarf Wedge Mussel is a small freshwater mussel once found in locations from North Caroline to New Brunswick with 70 population locations. However, in recent decades the population of mussels has shrunk to approximately 20 locations in eight watersheds. As filter feeders, mussels…

installation of "fish elevators". Fish elevators are a more natural way for the fish to make the crossing past the dam. The elevator has different sections that are increasing in height. The salmon use their natural ability to jump to progress higher and higher until they have reached the other side of the dam. However these contraptions are not for every dam. Only smaller dams can benefit from this process. Larger dams such as the Grand Coulee Dam cannot make use of fish elevators. Fish…
