Abundance and Distribution Patterns of Nekton and Micronekton in the Northern California Current Transition Zone
The epipelagic and mesopelagic nekton communities of the northern California Current have been sampled somewhat continuously over the last four decades with bottom and pelagic trawls, small midwater trawls, and purse seines. We review the zoogeography and community and environmental associations of the dominant pelagic micronekton and nekton species in this region with a view to understanding t...
متن کاملToward a Fisheries Ecosystem Plan for the Northern California Current
Recently the congressionally established Ecosystem Principles Advisory Panel issued a report on how best to amend single-species management. A major recommendation was that fisheries management councils develop a fisheries ecosystem plan (FEP) for every ecosystem under their jurisdiction. This document would be an umbrella document containing detailed information on the structure and function o...
متن کاملPrey selection by mosquitofish (Gambusia affinis) in California rice fields: effect of vegetation and prey species.
Mosquitofish are widely used for biological control of mosquito larvae in rice fields, but the presence of different types of vegetation or alternative arthropod prey affects the performance of the fish. Feeding experiments were conducted in 4 rice field vegetation zones. Overall, predation was maximal in young and mature rice, moderate in the submerged naiad vegetation, and minimal in areas of...
متن کاملThe impact of El Niño events on the pelagic food chain in the northern California Current.
The zooplankton of the northern California Current are typically characterized by an abundance of lipid-rich copepods that support rapid growth and survival of ecologically, commercially, and recreationally valued fish, birds, and mammals. Disruption of this food chain and reduced ecosystem productivity are often associated with climatic variability such as El Niño events. We examined the varia...
متن کاملThe spatial distribution of euphausiid aggregations in the Northern California Current during August 2000
The location and size of euphausiid aggregations (patches) were identified using acoustic volume backscattering strength at 38 and 120 kHz and vertically stratified MOCNESS sampling during a US GLOBEC cruise off southern Oregon and northern California in August 2000. Euphausiid patches were clustered inshore of Heceta Bank (44.01N) and off Cape Blanco (42.81N), but were not common elsewhere. Th...
