Benthic fluxes of carbon dioxide (CO2) and methane (CH4) were evaluated in grass carp Ctenopharyngodon idella (G), silver carp Hypophthalmichthys molitrix (S), and bighead carp Aristichthys nobilis (B) polyculture systems, to which topmouth culter Erythroculter ilishaeformis (T), Pacific white shrimp Litopenaeus vannamei (P), or common carp Cyprinus carpio (C) were added. These systems, GSBT, G...

In this study adsorption of arsenic (As) onto TiO2 nanoparticles and the facilitated transport of As into carp (Cyprinus carpio) by TiO2 nanoparticles was examined. Adsorption kinetics and adsorption isotherm were conducted by adding As(V) to TiO2 suspensions. Facilitated transport of As by TiO2 nanoparticles was assessed by accumulation tests exposing carp to As(V) contaminated water in the pr...

Bacterial isolates from common carp (Cyprinus carpio L.) and rainbow trout (Oncorhynchus mykiss) were identified by the API 20E system (bioMérieux). Twenty one isolates were identified as Shewanella putrefaciens. These isolates were tested for selected biochemical and cultural characteristics. Pathogenicity of two isolates (Pt38 and K116) for freshwater fish was assayed. Biochemical characteris...

Sedation of fish before handling and transporting can help curtail undue stress that affect their health. This study investigated the effectiveness sodium bicarbonate (NaHCO3) utilised as an anaesthetic agent for common carp (Cyprinus carpio) with average weight 13.5 ± 0.55 g. The experimental were grouped exposed to different concentrations at 0, 40, 45 50 g L–1 NaHCO3 dissolved in water. Fish...

Both adult females and males of Argulus mongolianus Tokioka, 1939 were collected from the buccal cavity wall body surface freshwater fishes in Lake Izunuma Uchinuma, Miyagi Prefecture, northen Honshu, Japan. The original description species was insufficient, based on a single female Inner Mongolia, China, no further has been made to date. Thus, this paper redescribes A. newly-collected specimen...

In order to efficiently manage nonindigenous species (NIS), predictive tools are needed to prioritize locations where they are likely to become established and where their impacts will be most severe. While predicting the impact of a NIS has generally proved challenging, forecasting its abundance patterns across potential recipient locations should serve as a useful surrogate method of estimati...
