Martínez Ciencias de la Tierra carp free Water ammonia pollution Guadalupe Reservoir, on the San Cayetano river, feeds into the Lerma river about 18 km north of Toluca in the State ofMexico, Mexico. On August 9, 1995, more than 6000 Israeli carp (Cyprinus carpio v. specularis and rubrofruscus) died within aweek in this reservoir. We investigated the cause of the fish mortality and we determined whether the reservoir could be used againfor carp culture. Five days after the accident the residual chlorine was 4 times higher than the maximum permissible amount.Ammonia nitrogen, biochemical oxygen demand (BOD) and chemical oxygen demand (COD) were also above the recommendedlevels. Six months later, the amount of some contaminants in the water, such as chlorine, were back to normal ranges of waterquality criteria for aquaculture. Ammonia, BOD and COD concentrations were lower to those found in the previous analyses butremained higher than the recommended levels. Most probably, residual chlorine was the cause of carp mortality as the chlorinelevel was very high when the fishes died. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841410 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.41 |
