“…Analysis of the data set with a general linear model revealed that sex had no influence on brain ChE activity or on the way this enzyme was inhibited by the pesticides. The literature contains little information concerning this issue, but this result is in line with that of Chuiko et al [31], who found the same to be true for the roach ( Rutilus rutilus ). Perhaps more surprisingly, acclimation temperature also has no effect on brain ChE activity in the snakehead.…”

With the expansion of agricultural areas within the Mekong River Delta in Vietnam, a concurrent, dramatic increase has occurred in agrochemical usage. To date, little consideration has been given to the negative impacts of this agricultural activity on the aquatic resources of the region. Both acute toxicity and subacute effects on brain cholinesterase (ChE) of two of the most commonly used insecticides, diazinon and fenobucarb, on adult native snakehead (Channa striata) were evaluated in a static, nonrenewable system, the environmental parameters of which, such as dissolved oxygen, water temperature, and pH, fluctuated similarly to field conditions. Four levels of insecticides, from 0.008 to 0.52 mg/L (for diazinon) and from 0.11 to 9.35 mg/L (for fenobucarb), were tested to assess the effects on the brain ChE activity of the snakehead up to 30 and 10 d for diazinon and fenobucarb, respectively. Diazinon was highly toxic to this fish species, with a 96-h median lethal concentration (LC50) of only 0.79 mg/L, and it also caused long-term ChE inhibition, with activity still significantly inhibited by 30% after 30 d for the three highest concentrations. Fenobucarb was less toxic to this species, with a 96-h LC50 of 11.4 mg/L. Fenobucarb caused more rapid ChE inhibition but also rapid recovery. The results of the present study indicate an urgent need to regulate the usage of these pesticides in the Mekong River Delta.

“…Chuiko et al (1997) determined the existence of seasonal fluctuations of brain AChE activity in freshwater fish Rutilus rutilus, showing the highest enzyme activity values at the beginning of summer and the lowest in winter. Moreover, in the migratory species Anguilla anguilla significant differences in the AChE activity among seasons were also reported, with the highest activities found in summer and the lowest in autumn (Guimaraes et al, 2009).…”

“…To our knowledge, there is scarce information regarding the enzymatic pathways of sharks, specifically concerning ChE, but generally existing data suggests that activity levels might oscillate seasonally, due to size, sex, and dietary composition (Beauvais et al, 2002;Chuiko et al, 1997Chuiko et al, , 2003Flammarion et al, 2002;Kirby et al, 2000;Sturm et al, 1999b). These correlations between ChE activity rates and physiological characteristics are, however, not always observed (Solé et al, 2006;Tortelli et al, 2006).…”
