Species Composition and Distribution of Pelagic Cephalopods from the Pacific Ocean off Oregon
MUCH OF OUR PRESENT KNOWLEDGE about the species composition and distribution of ceph alopods of the Pacific Ocean is derived from collections made on cruises of the "Albatross," steamer of the U.S. Fish Comm ission, dur ing the late nine teenth and early twentieth centuries. "Albatross" collections along the west coast of North America were taken mainly off California and Central America or Ala...
متن کاملThe Origin and Initial Rise of Pelagic Cephalopods in the Ordovician
BACKGROUND During the Ordovician the global diversity increased dramatically at family, genus and species levels. Partially the diversification is explained by an increased nutrient, and phytoplankton availability in the open water. Cephalopods are among the top predators of today's open oceans. Their Ordovician occurrences, diversity evolution and abundance pattern potentially provides informa...
متن کاملModelling Seasonal Distribution of Pelagic Marine Fishes
The distribution of pelagic marine fishes and invertebrates varies seasonally. However, information on the seasonal variation of the distribution of most pelagic marine fishes and invertebrates is scarce. In this paper, seasonal changes in distribution ranges of commercially exploited pelagic fishes and invertebrates are predicted based on the existing Sea Around Us Project distribution, a pred...
متن کاملDOCUMENT SARM-10-14b VERTICAL DISTRIBUTION OF 17 PELAGIC FISH SPECEIS IN THE LONGLINE FISHERIES IN THE EASTERN PACIFIC OCEAN
S Pelagic deep longline was widely used in targeting tunas of high economic values with other fish species caught incidentally as bycatch. Identifying characteristics of vertical distribution of fish species that interact with longline can provide critical information needed for the development of effective measures to mitigate bycatch species and is essential for ecosystem conservation. Much w...
