Creator:: Castillo, Gonzalo C.
Abstract:: The extent of biological invasions, their role on the feeding of native fishes and their impact on community stability were investigated in Alsea Bay and Yaquina Bay, two estuaries on the central Oregon coast, USA. Most nonindigenous species (NIS) introduced in these intermediately invaded estuaries are considered byproducts of culturing...

Creator:: Powell, Allyn B.
Abstract:: Atlantic menhaden, compared to gulf menhaden, exhibit a life history pattern that appears to be adapted to a more unpredictable reproductive environment. From experiments on laboratory-reared eggs and larvae, Atlantic menhaden have larger eggs with larger yolk volume. They are larger at hatching, utilize their yolk faster, begin feeding at...

Abstract:: The distribution of herring (Clupea harengus pallasi) in the Northeast Pacific extends from southern California to northern Alaska. Studies on variation in herring life-history are limited to local characteristics and recruitment populations or relatively restricted regions of the Northeast Pacific. In this study I assessed herring life-history patterns and recruitment...

Creator:: Harris, Phillip M.
Abstract:: The early life history stages and metamorphosis in Dover sole (Microstomus pacificus) are described from 201 larvae and juveniles. Unlike other pleuronectids, with the possible exception of the deep-sea sole (Embassichthvs bathvbius), initial migration of the left eye is not associated with metamorphosis or transition from plankton to benthos. The...

Creator:: Toole, C. L. (Christopher L.)
Abstract:: Demographic characteristics of juvenile Dover sole (Microstomus pacificus) were examined in relation to physical and biotic factors to develop a hypothesis explaining annual variations in recruitment. Surveys were conducted along the Oregon continental shelf at depths between 50-400 m bimonthly during 1989 and annually (in March) between 1990 and 1993....

Creator:: Wilson, Christopher D.
Abstract:: The use of some age determination methods may result in the incorrect age structure of fish populations. This in turn may lead to incorporation of inappropriate data into models used for stock management. Otoliths are commonly used for determining the age of fishes, and ages based on the whole otoliths...
