The 13 species of shrimps studied for this thesis were collected
off the Oregon coast. The family Oplophoridae is well represented
in this area. Five of the seven known genera were identified.
Hymenodora frontalis, H. glacialis, and H. gracilis were described
and further differentiating characters were illustrated. Other members
of...
A study was done on the zoogeography of species of oceanic
shrimp in the North Pacific from 22°N to 56°N and from 124°W to
145°E, using samples of shrimp collected from 1954 to 1969. These
collections were made during the following cruises: John R. Manning
Cruise 22, and the Hugh...
A method for isolating the salt gland (SG) from the larval brine
shrimp has been developed. This extra-renal organ is removed from 5-10%
of Stage Inauplii by vortexing after incubating the animals at 37°C for
8 hours in a saline solution buffered with 100 mM sodium phosphate at pH
7.6....
The brine shrimp, Artemia, was used as an experimental
organism to study the effects of ⁶⁰Co gamma irradiation on the reproductive
performance of an animal population. The total reproductive
ability of the brine shrimp was fractionated into various components
and the effects of irradiation on each of these components
was...
The objective of this study was to identify and investigate the
underlying basis for the increasing volume of U.S. imports of fishery
products from 1958-1969. It was recognized that many institutional
constraints contributed to the high marginal cost of domestic harvesting
which placed the United States at a comparative disadvantage...
Shrimp waste samples were extracted with a variety of organic solvents. Each fraction was measured for antioxidant activity by determining the rate of oxidation of β-carotene-linoleic acid in an emulsion system. An ethanol extract exhibited the highest antioxidant activity. Purification of the most active fraction was accomplished by thin layer...
Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...
Two indigenous species of burrowing shrimp inhabit and often dominate the intertidal zone of estuaries along the US West Coast, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species are considered ecosystem engineers and play a role in maintaining estuarine health and ecosystem function. They...
