“…Sensitivity of an organism to any chemical varies with fish size and species (Sprague, 1971). Values of 24‐h and 96‐h LC for trichlorfon in juvenile yabbies ( Cherax destructor ) were 0.351–1.167 and 0.018–0.093 mg L −1 , respectively (Qin and Dong, 2004). However, Cebrian et al.…”

“…Organophosphates are considered highly toxic to many aquatic species (Qin and Dong, 2004). Additionally, important organs of fish can be affected by organic pesticides such as in the gills (Gill et al., 1988; Guimarães et al., 2007), the liver (Gill et al., 1988; Rodrigues et al., 2001; Fanta et al., 2003) and in the kidney (Gill et al., 1988; Veiga et al., 2002).…”

“…The most common insecticides used are the organochlorine endosulfan, the organophosphate trichlorfon and its by‐product dichlorvos (Table 4). Several studies (Ludwig 1993; Qin & Dong 2004) have assessed the toxicity of trichlorfon on zooplankton species (rotifers, cladocerans and copepods); these studies have shown that these organisms are highly sensitive to the concentrations recommended to be used in finfish treatments (300 μg L −1 ) in countries like Thailand (Tonguthai 2000) and China (Yulin 2000). The sensitivity of different taxonomic groups of aquatic organisms has been investigated for a range of insecticides (which are also widely used in agriculture production) by comparing toxicity data derived in laboratory and semi‐field experiments; these studies have demonstrated that aquatic crustaceans and insects are the most sensitive taxa of non‐target organisms potentially affected by residual concentrations of these compounds, followed by fish (Maltby et al.…”

Over the past few decades, Asian aquaculture production has intensified rapidly through the adoption of technological advances, and the use of a wide array of chemical and biological products to control sediment and water quality and to treat and prevent disease outbreaks. The use of chemicals in aquaculture farms has raised environmental concerns owing to their potential impacts on downstream aquatic ecosystems. Currently little is known about the environmental fate and effects of the chemicals used in Asian aquaculture. Consequently, we reviewed recent information on the use of chemical and biological products in the most important Asian aquaculture producing countries and briefly summarize their main potential environmental impacts. We provide an overview of the main factors controlling the use of these chemicals and describe the international risk assessment guidelines available for aquaculture chemicals. Finally, data gaps and research needs for their implementation in Asian countries are discussed. Our review aims to form a basis for developing environmental risk assessment studies of the chemicals used in Asian aquaculture

“…() reported an LC50 (48 hr) of 0.29 μg L −1 , which is quite similar to the LC50 (48 hr) of 0.26 μg L −1 reported by Yoshimura and Endoh (), whereas Ecete, Ramírez, Jiménez, and Cano Carmona () reported an LC50 (24 h) of 0.088 (±0.04) mg L −1 . Moreover, a wide range of sensitivity to trichlorfon has been previously reported in invertebrates (Qin & Dong, ).…”

Summary The eradication of the haematophagous isopod ectoparasite Gnathia maxillaris was not achieved after several years of physical elimination of larvae by filtration and chemical treatment with trichlorfon in a captive marine fish population in exhibition aquaria. In this study, different in vitro laboratory assays were performed to find effective alternative anti‐parasitic treatments to trichlorfon (lufenuron, emamectin benzoate, cypermethrin and abamectin). The lethal concentration 50 (LC50) values at 96 hr were calculated for each compound using both larval stages (zuphea and praniza); morphological deformities generated throughout the life cycle, reduction in egg laying and survival of adult forms were also determined. Abamectin, cypermethrin and emamectin benzoate proved effective at limiting further Gnathia maxillaris development, but their efficacy at eradicating an infestation in large tanks was not supported by laboratory assays. However, the use of lufenuron proved to be a good substitute for trichlorfon when treating this type of infestation in large‐volume tanks (LC50 55.8 mg m−3 for praniza). Routine lufenuron treatment once a month via an oral dose at 10 mg kg−1 body weight eradicated G. maxillaris from the exhibition aquaria.
