Dynamics of juvenile salmon and forage fishes in nearshore kelp forests

چکیده

North-east Pacific juvenile salmon and forage fishes, including the endangered species Chinook (Oncorhynchus tshawytscha), coho kisutch), chum keta), pink gorbuscha), fishes of herring (Clupea pallasi), surf smelt (Hypomesus pretiosus), sand lance (Ammodytes hexapterus), utilize kelp environments. Many details forest ecosystem function for these are lacking. Kelp forests, salmon, declining precipitously as global climate shifts developments along coastal shorelines expand. It is therefore essential to understand species. Analysis 7 years snorkelling survey videos indicates that both use forests throughout outmigration season, their interactions occur in small large groups, primarily outer edge beds. Over course outmigration, encounter first, followed by herring. The majority intermingling, which a subset proceed predation, on important develop implement specific fishery habitat conservation measures preserve restore functions. Long-term research has shown intact, conserved nearshore habitats better ecologically than restored habitats, individual can differently salmon. Therefore, plans should be developed conserve wild documented provide protecting them from various development impacts, dredging, filling, water-quality decline. Coastal restoration often only successful when ecosystem-limiting factors result loss resolved. restoration, therefore, prioritized regions known high historical importance, with actions focused correcting limiting caused and/or degradation.

The vertical distribution of juvenile salmon (Oncorhynchus spp.) and associated fishes in the Columbia River plume

Simultaneous trawling at surface and at depth at one location off the Columbia River, Oregon, in June 2000 identified the depth distribution of juvenile salmonids and associated fishes. Juvenile salmon off the Columbia River were distributed primarily near the surface, within the upper 12 m. Highest densities of subyearling chinook salmon (Oncorhynchus tshawytscha) off the Columbia River were a...

Parasitism and food web dynamics of juvenile Pacific salmon

There is an increasing realization of the diverse mechanisms by which parasites and pathogens influence the dynamics of host populations and communities. In multi-host systems, parasites may mediate food web dynamics with unexpected outcomes for host populations. Models have been used to explore the potential consequences of interactions between hosts, parasites and predators, but connections b...

Brodeur Et Al.: Pelagic and Demersal Fish Predators on Juvenile and Adult Forage Fishes

A requisite for reliable food web models and ecosystem-based management in regions such as the California Current is the availability of diet information on key predators. In upwelling ecosystems, much of the lower trophic level energy may be transferred through a relatively small set of very abundant pelagic forage fish taxa, such as anchovies, sardines, smelts, and herring. In addition the pe...

Impact of the Oil Spill on Juvenile Pink and Chum Salmon and Their Prey in Critical Nearshore Habitats

The objective of this study was to determine the impact of the Exxon Valdez oil spill on juvenile pink and chum salmon during their initial period of residency in nearshore marine habitats of western Prince William Sound. In oiled locations, both pink and chum salmon fry in the nearshore marine environment were contaminated by hydrocarbons in 1989, but not in 1990. Field observations and labora...
