Young-of-the-year rockfish (Sebastes spp.) settlement dynamics in Oregon estuaries

Creator:

Abstract:

In the Pacific Northwest, several species of rockfishes (Sebastes spp.) are under extreme conservation measures due to low population levels. Although currently at healthy population levels, one species of interest is the black rockfish (S. melanops), which has been shown to utilize estuarine habitat during its early life history stages....

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:

Litz, Marisa N. C.

Abstract:

Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

Land-based polyculture of chinook salmon, Oncorhynchus tshawytscha; Manila clams, Tapes japonica (Deshyes); and red macroalgae, Palmaria mollis

Creator:

Moosapanah, G. Reza

Abstract:

This investigation demonstrates the feasibility of a polyculture system using effluent water from land-based salmon culture systems to feed juvenile Manila clams, Tapes japonica (Deshyes), and an evaluation of an artificial diet for feeding juvenile clams. An economic analysis of the polyculture system was compared to cultures of a single...
