A preliminary observation on water quality and plankton of an earthen fish pond in Bangladesh: recommendations for future studies.
The present study provides a characterization of water quality and plankton samples in earthen fish pond in Rajshahi, Bangladesh. Sampling was done over a period of six months, running from October, 2004 through March, 2005. All the water quality parameters were within the optimal ranges for plankton productivity. Temperatures varied from 19.75 to 27.25 degrees C; transparency, 24.75-29.50 cm; ...
متن کاملInfluence of inlet water on the biotic and abiotic variables in a fish pond.
The effects of treated and untreated water inlets with macrophytes on the improvement of water quality and zooplankton community were evaluated in a fish pond with continuous water flow. Water and zooplankton samples were retrieved at four sites during nine months. There were differences (p<0.01) between inlet water from fish pond and inlet water from canal with macrophytes, featuring higher co...
متن کاملWater flow around a fish mimic attracts a parasitic and deters a planktonic copepod
Fish typically evoke a flight response in copepods. The behaviour of infective stage parasitic copepods, Lepeophtheirus salmonis, and adult holoplanktonic copepods, Acartia spp., in response to the approach of a rubber fish mimic was compared. Responses were scored as attacks if the copepod moved closer to the head or escapes if it moved further from the head. The parasite attacked the mimic in...

متن کاملBig Fish in Small Pond or Small Fish in Big Pond? An Analysis of Job Mobility
Big Fish in Small Pond or Small Fish in Big Pond? An Analysis of Job Mobility The statement that individuals care for status and for their position within a hierarchy has been subject to sparse economic analysis. I check this assertion by analyzing wages and status within the firm, with status measured as the worker rank in the firm wage hierarchy. More precisely, I focus on worker mobility bet...
