Review Of Ecology And Fishery Of The Olympia Oyster, Ostrea Lurida With Annotated Bibliography, P Baker Jan 1995

Review Of Ecology And Fishery Of The Olympia Oyster, Ostrea Lurida With Annotated Bibliography, P Baker

VIMS Articles

The Olympia oyster, Ostrea lurida,is a small bivalve mollusk species native to the western United States and Canada. It was commercially important in the late 19th century, and was cultured in Washington State until a near-collapse of the industry in the 1950s. Since then it has made a minor commercial comeback, but has been largely superseded by the introduced Crassostrea gigas. Most significant literature dates from prior to the collapse of the industry in the 1950s, and much of this is comprised of state or federal agency reports, or similar obscure literature formats. This document is divided into 2 parts; …


Nitrification Potentials Of Benthic Macrofaunal Tubes And Burrow Walls: Effects Of Sediment Nh4+ And Animal Irrigation Behavior, Ms Mayer, L Schaffner, Wm Kemp Jan 1995

Nitrification Potentials Of Benthic Macrofaunal Tubes And Burrow Walls: Effects Of Sediment Nh4+ And Animal Irrigation Behavior, Ms Mayer, L Schaffner, Wm Kemp

VIMS Articles

We examined the natural variation of nitrification potentials (NPs) of surface sediments and macrofaunal tubes and burrow walls in relation to sediment NH4+ level, season, and macrofaunal species. NP (the ability of a unit of sediment to oxidize NH4+ when NH4+ and O-2 are not limiting) is an index of the abundance and activity of nitrifying bacteria which we measured in slurries with the chlorate block technique (nmol NO2--N produced g(-1) dry weight sediment h(-1)). The NP of the tubes of the polychaete Loimia medusa was positively related to sediment NH4+ (KCl-extractable) concentration at 3 sites where tubes were collected …
