| Descripción | Some herbicides are considered by the U.S. Environ-mental Protection Agency (EPA) to be pollutants in rivers, coastal lagoons, estuaries, and irrigation canals due to their high toxicity, persistence, and mobility (Hirata 2002). Among these herbicides is diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea), a compound used in cotton, pineapple, and sugarcane crops for weed control. It is soluble in water and volatile; under certain Another herbicide widely used in corn and sugarcane crops in Veracruz, Mexico, is glyphosate (Zuleta-Rodríguez & Vázquez-Torres 1992). In this region, many glyphosate-based herbicides are used, a compound that affects water quality and organisms by modifying their structure and functionality (Torres 2017). Glyphosate is highly soluble in water, and under certain conditions, it is moderately toxic to aquatic crustaceans (PPDB 2019b) |
| Objetivo | The objective of this work was to evaluate the acute toxicity of the commercial herbicides Karmex® (diuron: DCMU 3-(3,4-dichlorophenyl)-1,1-dimethylurea) and Herbipol® (glyphosate: N-(phosphonomethyl) glycine) on the megalopae of Callinectes sapidus and measure their relative abundance in the association of larval and postlarval species of crustaceans from the estuary of the Jamapa River, Veracruz. |

| Forma en como se construyen los datos | Callinectes sapidus postlarvae were collected in two samples using white light traps made from plastic boxes (Cházaro-Olvera et al. 2018). The traps were placed overnight on the jetty of the Technological Institute of Boca de Río Veracruz at the site located at 19°05'50.23"N and 96°06'36.97"W (Fig. 1). The boxes for the collection were placed at 20:00 h on the first day and removed at 09:00 h the next day. The physicochemical parameters were measured at each site with a previously calibrated Hanna® HI 9828 multiparametric. For the in vivo sample, C. sapidus megalopae were selected under the microscope in 60 mm diameter Petri dishes to perform the bioassays. The rest of the sample was fixed with 70% alcohol and labeled with the date and place of sampling. |
