“…Several studies have reported the development of bacterial resistance to antimicrobials in different types of aquacultural production (7,13,14,(16)(17)(18)(19)(20). However, there are few available data about the incidence of drug-resistant bacteria in intensive freshwater culture of eels (3).…”

The occurrence of strains that are resistant to oxolinic acid, oxytetracycline, sulfamethoxazole-trimethoprim, and nitrofurantoin among heterotrophic bacteria, including human and fish pathogens, in two freshwater eel farms was investigated. High levels of individual-and multiple-drug-resistant bacteria were detected, although sampling events were not correlated with clinical outbreaks and drug therapy.

“…In the Handan Reach, metallurgy is the primary source of wastewater, and in the Wangyang Ditch, pharmacy is the most important source of wastewater. The impaired benthos is always coupled to significant exposure to toxins, such as heavy metals (Ciutat et al 2005) and antibiotics (Chelossi et al 2003). The pharmacy industry can produce large amounts of antibiotic wastewater (Jun and Zhengyu 1997), and metallurgy wastewater contains many heavy metals.…”

Dissolved oxygen (DO) microprofiles of prepared sediments from 24 sampling sites in the Fuyang River were measured using a gold amalgam microelectrode in this study. The measured microprofiles can be divided into four types. In type I profiles, DO kept constant in the overlying water and decreased smoothly in the pore water; in type II profile, DO showed fluctuation in the pore water; in type III profiles, DO showed peak in the SWI; in type IV profiles, DO decreased obviously in the overlying water. Type I profiles indicated the absence of benthic organisms and thus the degradation of the sediment habitat. Type II and III profiles indicated the activity of benthic animal and epipelic algae, which is common in the healthy aquatic sediment. Type IV profiles indicated that the excessive accumulation of pollutants in the sediment and thus the serious sediment pollution. There are nine sites showing type I profile, three sites showing type II profile, nine sites showing type III profile, and three sites showing type IV profile in the Fuyang River. The dominance of type I and appearance of type IV indicated that sediment oxygen consumption processes in the Fuyang River were strongly influenced by the sediment pollutants release and the vanish of benthic organisms. The pharmacy, metallurgy, and curriery industries may contribute to the sediment deterioration and thus to the occurrence of type I and type IV oxygen profiles in the Fuyang River.

“…El excesivo uso de antibióticos aplicados en acuicultura en Chile está relacionado con el tipo y frecuencia de enfer medades, pero su uso en altas dosis puede afectar también a poblaciones naturales de organismos costeros (For tt et al 2007), e incrementar en ellos, algunos de consumo humano, la resistencia frente a antibióticos (Chelossi et al 2003, Cabello 2006, Nonaka et al 2007, Heuer et al 2009, Buschmann et al 2012. Desencadenar respuestas epidemiológicas, como el caso del virus ISA u otras patologías, que generan un enor me impacto económico y social, tiene un componente ambiental relevante que no debe ser ignorado (Mardones et al 2009).…”
