Objective:To determine the acute toxicity of trichlorophon(an organ phosphorus compound used in agricultural fields and a common disinfectant used for fish diseases)towards two ornamental fish Systomus tetrazona and Hemigrammus erythrozonus.Methods:In this research,two aquarium fish were exposed to different concentrations of trichlorophon(5,10,20 and 40 mg/L)for 96 h and physicochemical properties of water used for these experiments were stable and every mortality was recorded daily for 96 h.LC_(50) of 24 h,48 h,72 h and 96 h were attained by probit analysis software SPSS version 16.Results:The 96-h LC_(50) of trichlorophon for Systomus tetrazona and Hemigrammus erythrozonus were 8.74 and 8.88 mg/L,respectively.Conclusions:Eventually,toxicity values indicated that trichlorophon has the same toxicity towards the studied species and the lower value of LC_(50) for studied species in comparison with that of most species can be stated.

Heavy metals disposed through anthropogenic activities find their way into aquatic environment through factory effluents. These heavy metals resuspend back into the water column along with the sediments and are known to affect aquatic bioresources. Effluent water samples and crabs were collected along top camp stream to evaluate heavy metal concentrations and were assessed to determine the uptake of heavy metals in crabs. Results show fluctuation in acidity/alkalinity of water samples. BOD, COD, DO, conductivity and organic phosphorous were below permissible limit, and metal concentrations (As, Cu, Cr and Zn) in water samples do not constitute a risk factor for human health. However, concentrations of Cupper (Cu), Iron (Fe), Asenate (As) and Manganese (Mn) in crabs were significantly higher than the level found in the effluent water. Heavy metal poisoning has been identified among people that depend on crabs for their protein. Such effects are viewed by international health organization as attenuation of human health. The toxic elements (As, Cu, Fe and Mn) in the effluent and dissolved solid concentrations including potassium and calcium carbonate may be reduced through resource recovery.

The volume of production and marketing of China's conventional aquatic products is increasing. Compared with price of livestock and poultry products,price of conventional aquatic products is relatively low. Differentiated brand marketing for China's conventional aquatic products is a key approach for increasing market demand for conventional aquatic products and increasing value of conventional aquatic products. The differentiated brand marketing is an inevitable trend of market development and also a powerful arm for market competition. China's conventional aquatic products can take differentiated brand marketing strategies such as brand orientation,brand concept,brand culture,and place name brand,to better keep market competitive edge and increase economic benefits.

蕹菜（Ipomoea aquatic Forsk.）又称空心菜、通菜、藤菜、竹叶菜和蓊菜等,为旋花科一年生草本植物,依其结实与否分为籽蕹和藤蕹两种类型,以叶和嫩茎供人们食用,是夏秋渡淡的主要绿叶蔬菜之一,在长江流域广泛栽培。因蕹菜茎叶繁茂、种植地多荫蔽潮湿,利于各种害虫的孳生和为害。但我们走访菜农发现,他们对蕹菜上发生的一些害虫种类未能正确识别,在防治上常常是凭经验用药,乱用、滥用现象普遍,严重影响了蕹菜的品质。
