Ecological Impact of Grass Carp: A Review of the Available Data
The exotic grass carp ( Ctenopharyngodon idella ) has been used for almost a half a century in the United States as a biological agent to control and manage aquatic plants. This long-lived generalist herbivore consumes large amounts of vegetation and can considerably alter habitat and impact aquatic communities. We conducted a literature review to determine whether previous studies adequately a...
متن کاملA Review of Grass Carp Use for Aquatic Weed Control and its Impact on Water Bodies
The state of knowledge of grass carp ( Ctenopharyngodon idella Val.) effects on water bodies are summarized based on a review of selected literature and my own experience from South Bohemian ponds. The subjects considered include aquatic plant control using grass carp, fish age and stocking densities, and direct and indirect consequences of its introduction to water bodies including impacts on ...
متن کاملEmbryonic and Larval Development and Early Behavior in Grass Carp, Ctenopharyngodon idella: Implications for Recruitment in Rivers
With recent findings of grass carp Ctenopharyngodon idella in tributaries of the Great Lakes, information on developmental rate and larval behavior is critical to efforts to assess the potential for establishment within the tributaries of that region. In laboratory experiments, grass carp were spawned and eggs and larvae reared at two temperature treatments, one "cold" and one "warm", and track...
متن کاملJuvenile grass carp in the Waikato River, May 1997
1. Introduction A small-sized grass carp (43 cm long) was caught in Lake Whangape, lower Waikato River basin, in May 1997. This fish was too small to be a recapture from the escapement from trial sites in 1984 (fish which are now mostly longer than 70 cm), so could have been either a recent escapee, or the result of natural reproduction in the river. Either way, the finding of this fish indicat...
متن کاملMolecular Cloning, Characterization and Expression Analysis of Macrohage-Colony Stimulating Factor 2 Gene from Grass Carp (Ctenopharyngodon idellus)
Macrophage colony-stimulating factor (CSF-1/M-CSF) is a key factor for the differentiation, growth and survival of monocytes/macrophages and osteoclasts. The functions of M-CSF have been well characterized in mammals. In this study, we have cloned and sequenced the cDNA of M-CSF2 in grass carp. The grass carp M-CSF2 cDNA was 1487 bp in length, containing an open reading frame of 855 bp that enc...
