Metabolism of the Thiocarbamate Herbicide Molinate (Ordram) in Japanese Carp... 

Molinate (S-ethyl hexahydro-azepine-l-carbothioate) has been widely used for broadleaf and grass weed control in rice culture. The 96-hour LC50 of technical molinate in the common goldfish is 30 ppm (1) and the medium tolerance limits (LTm) for molinate in mosquito fish (Gambusia affinis) are 16.4 ppm for 96 hours (J2). Kawatsu (3) estimated the 20-day lethal concentration of molinate in Japanese carp (Cyprinus carpio) var. Yamato koi at 0.18 ppm. However, there was no toxic effect of molinate on American carp at concentrations of 10 ppm during a two-week observation (40. ... 

The purpose of this study was to investigate the extent of accumulation and the fate of molinate in the Japanese carp. 

Treatment of Fish, Japanese carp (Cyprinus carpio) variety Yamato koi imported from Nagano, Japan, were fed carp food No. 3 (Yashima Chemical Co., Japan) containing 30% crude protein, 10% fat and 12% ash. The fish were acclimated for 30 days in the laboratory at 21 2°C.

Among the freshwater species, the ayu, channel catfish, coho salmon, and rainbow trout require 18 3n-3 or EPA and/or DHA. Chum sahnon, common carp, and Japanese eel require an equal mixture of 18 2n-6 and 18 3n-6. Nile... 

At the meeting of the Chemical Substances Council held by the Japanese government in 2004, it was reported that a bioconcentration study was conducted in 2003 with SCCPs with Cn and Cly, g, 9, lo (chlorine 62.5, 65.7, 68.5 and 70.9%) containing 1% of stabilizer and the quantitative data on each individual substance were obtained [13]. The study was conducted with flow-through system at concentrations of 1 and 0.1 pg of SCCPs, and 20 mg of 2-metoxyethanol was used as dispersant. Liquid chromatography/mass spectrometry (LC/MS) was used for the analysis of the test species, carp Cyprinus carpio). After 62-day exposure, a 14-day excretion study was also conducted. The result is shown in Table 6.
