The status of the ocean shrimp resource and its management

The fishery for ocean shrimp (Pandalus jordani) was began in the early 1950's after exploratory fishing by the Department of Fish and Game discovered five dense concentrations. The fishery has been fully regulated since its beginning and is currently being managed for maximum sustained yield by a quota system. (19pp.

California shellfish importation and planting report 1973-1974 season

The amount of shellfish imported and planted in State waters is enumerated by species and compared with the previous season. Arrangements were made with the Washington State Department of Fisheries to inspect the bulk of the seed oysters originating in Washington State. One shipment of 1,330 cases of Pacific oyster, Crassostrea gigas, seed was imported from Japan. Adult Eastern oysters, Crassostrea virginica, were inspected upon arrival in San Francisco. Experimental studies with seed from mortality resistant parents indicate good survival and growth. (5pp.

The Augsburg Confession in Context (Part 1)

Lutherans cannot truly look forward into the 1980s without first looking back to the 1520s and 1530s — to the “confessional rocks” from which they were hewn

California shellfish importation and planting report 1975-1976 season

The amount of shellfishes imported and planted in State waters is enumerated by species and compared with the previous season. Total giant Pacific oyster seed shipments were equivalent to 5,249 standard cases, compared with 11,884 standard cases the previous season. Sources of these seed oysters were Japan, Washington State and British Columbia, Canada. Adult Eastern oyster shipments from New York State totaled 442 bushels. (5pp.

Ether and Electrons in Relativity Theory

This chapter discusses the roles of ether and electrons in relativity theory. One of the most radical moves made by Albert Einstein was to dismiss the ether from electrodynamics. His fellow physicists felt challenged by Einstein’s view, and they came up with a variety of responses, ranging from enthusiastic approval, to dismissive rejection. Among the naysayers were the electron theorists, who were unanimous in their affirmation of the ether, even if they agreed with other aspects of Einstein’s theory of relativity. The eventual success of the latter theory (circa 1911) owed much to Hermann Minkowski’s idea of four-dimensional spacetime, which was portrayed as a conceptual substitute of sorts for the ether

Selectivity of gillnets in the California Pacific herring roe fishery

Pacific herring, Clupea harengus, landings were sampled during the 1976 season in San Francisco, Tomales and Outer Bodega bays. Fish were sampled according to the type of gear used to catch them - - roundhaul nets (purse seines and lamparas), beach seines, and gillnets. Analysis of the data indicated that gillnets caught larger fish and caught more females than did roundhaul nets. In San Francisco Bay, female herring caught by gillnets had a mean body length of 208 mm (8.2 inches) compared to 179 mm (7.0 inches) for roundhaul nets. The sex ratio was 72% females by gillnets to 55% for roundhaul nets. The larger size and larger number of females caught by gillnets resulted in a much higher ripe roe recovery - - an average of 17.2% compared to 9.8% for roundhaul nets by weight of all samples. Although no definite comparisons of size and sex ratio of fish caught by different types of gear could be made in Tomales Bay and Outer Bodega Bay (because of insufficient sampling), herring in gillnet samples were comparable to those of San Francisco Bay in the two measured characters.
