Assessment Of Salmon Habitat On The Feather River, Nathan Sweem Aug 2014

Assessment Of Salmon Habitat On The Feather River, Nathan Sweem

STAR Program Research Presentations

Human activity in central valley streams has had a significantly negative impact on salmon habitat (Williams 2006). The presence of dams impedes sediment transport which is critical to salmon spawning (Williams 2006; Kondolf 1997). As part of an effort to enhance salmon spawning, the California Department of Water Resources added 7000 ft3 of gravel to Cottonwood Hatchery, Upper Auditorium, and Auditorium riffles on the Lower Feather River below the Thermalito Dam Complex in July of 2014. Stream conditions at Cottonwood Hatchery riffle were assessed by conducting analysis of sediment grain size, water depth and velocity, gravel permeability, and dissolved …


Aquaponics And Basil Plant Density, Danika L. Macmaster, Brook Murphy, Dudley Burton Aug 2014

Aquaponics And Basil Plant Density, Danika L. Macmaster, Brook Murphy, Dudley Burton

STAR Program Research Presentations

Aquaponics is the use of water from a fish tank to provide nutrients to plants in a soil-less environment. The rocks cultivate the bacteria that turns the ammonia into nitrates that the plants need, and the plant bed functions as a filter for the fish tank. In this study, with the guidance of Doctor Dudley Burton, Doctor Brook Murphy, we researched the optimal plant density for basil in an Aquaponics system. We attempted to control or measure all the other variables to consider, as to isolate the variable of distance between plants. The water flow was spread through the plant …
