Fish farms, parasites, and predators: implications for salmon population dynamics.
For some salmon populations, the individual and population effects of sea lice (Lepeophtheirus salmonis) transmission from sea cage salmon farms is probably mediated by predation, which is a primary natural source of mortality of juvenile salmon. We examined how sea lice infestation affects predation risk and mortality of juvenile pink (Oncorhynchus gorbuscha) and chum (O. keta) salmon, and dev...
متن کاملFloodplain farm fields provide novel rearing habitat for Chinook salmon
When inundated by floodwaters, river floodplains provide critical habitat for many species of fish and wildlife, but many river valleys have been extensively leveed and floodplain wetlands drained for flood control and agriculture. In the Central Valley of California, USA, where less than 5% of floodplain wetland habitats remain, a critical conservation question is how can farmland occupying th...
متن کاملAvian Foods, Foraging and Habitat Conservation in World Rice Fields
—Worldwide, rice (Oryza sativa) agriculture typically involves seasonal flooding and soil tillage, which provides a variety of microhabitats and potential food for birds. Water management in rice fields creates conditions ranging from saturated mud flats to shallow (<30 cm) water, thereby attracting different guilds of birds. Grain not collected during harvest (i.e. waste rice) is typically the...
متن کاملSaltmarsh as habitat for fish and nektonic crustaceans: Challenges in sampling designs and methods
This is a review of research into the ecological role of saltmarsh as habitat used directly by fish and nektonic crustaceans such as shrimp (prawns) and portunid crabs. The quality of information about direct use of saltmarshes by nekton is poor, with even the most influential works suffering from obvious limitations. Attempts to generalize about nekton use of saltmarshes are hampered by sampli...
متن کاملMulching effects on the yield and quality of garlic as second crop in rice fields
Plastic mulch increased minimum temperature of soil, accelerated plant height,early growth, early yield, and bring satisfactory weed control without anyapplication of herbicides. This experiment was laid out on three-factorialRandomized Complete Block Design with three replications during 2008-2010 atthe National Rice Research Institute, Rasht, Iran using three kinds of mulches(Transparent and ...
