“…Similarly, exposure of I. punctatus females to sublethal concentrations of CuSO 4 (0.22-0.46 mg L − 1 ) for 11 weeks showed no changes in length, weight, and body condition (Perkins et al, 1997). On the other hand, in Hypophthalmichthys molitrix larvae exposed to 0.15-0.30 mg L − 1 CuSO 4 , a decrease in the survival rate of fish was shown to be proportional to increases of the concentration of this chemical agent (El-Fiky, 2001). Exposure to CuSO 4 may change the feeding rate of fish, and also lead to negative effects on location and reach of food.…”

“…There is additional toxicity data available for other carp species. Copper sulfate at 0.15 mg/L or greater is toxic to larval silver carp [661]. Common carp larvae exposed to Cu at 0.2 mg/L Cu (as copper sulfate, CuSO 4 ) starting at 1 day post hatching had anterior and posterior swim bladder chambers that were 30% smaller than unexposed controls and about 24% of fish did not experience inflation of the anterior swim bladder chamber [654].…”

Grass carp (Ctenopharyngodon idella) are globally important in aquaculture and aquatic vegetation control. However, escaped grass carp have established invasive populations. A targeted keyword search was performed on a carp (order: Cypriniformes) literature database maintained by the U.S. Geological Survey to identify literature relevant to grass carp. Additional sources cited in reviewed documents and provided by numerous reviewers were also included. There were three focus areas designed to provide support for invasive grass carp management: (1) diet and behavior; (2) physiological constraints, toxicity, and biology; and (3) gut physiology. Each focus area provides information to guide development of potential pathways for invasive grass carp control. Information from other carp species was used to fill in gaps where grass carp information was lacking and provide additional, potential research directions. Diet-related information included food selection and aquacultural diet formulations. Behavioral information included stimuli and non-physical barriers to attract, repel, or stop movement. Physiological constraints, toxicology, reproductive control, and biological control provide a research review for control options. Gut physiology and related control pathways provide knowledge to improve toxin or pathogen delivery. This review provides a basis for developing approaches and research for controlling invasive grass carp populations, aquaculture, and native population management.

“…Because fish embryos and larvae have an important role in the trophic chain and, in the persistence of population as well, the use of these stages are relevant for the assessment of toxicity in the aquatic environment. Several reports have studied copper toxicity in early life stages of fishes (Barjhoux et al, 2012;El-Fiky, 2001;Kazlauskienë, 2002;Stasiūnaitė, 2005;Witeska et al, 2010).…”

The aim of this work was to study the impact of copper during a sub-chronic exposure to environmental concentrations in the early life stages of rainbow trout (Oncorhynchus mykiss). Eyed-stage embryos of rainbow trout, at 265°D, were exposed in semi-static conditions to sublethal concentrations of CuSO4 up to the larval stage (528 °D) under laboratory-controlled conditions. During 3 weeks, they were exposed to the environmentally-realistic concentration of 2 µg/L Cu and to a 10-fold higher concentration, 20 µg/L Cu. Several biological (survival, hatching success, malformation, growth) and behavioral (swimming activity) and molecular endpoints (genotoxicity and gene transcription) were studied. Exposure to 20 µg/L Cu had an inhibitory effect on hatching and increased half-hatched embryos (25%). At the end of the exposure, no significant differences were observed in growth of the larvae exposed to the highest Cu concentration. However, larvae exposed to 2 µg/L Cu exhibited increased growth in comparison with non-exposed larvae. The percentage of malformed larvae was significantly higher for both copper conditions, with skeletal malformations being the most observed. Expression of several genes was evaluated in whole larvae using quantitative real-time PCR. Genes involved in detoxification (gst, mt1 and mt2) and in cell cycle arrest (p53) were significantly repressed in both copper conditions when compared to control. In addition, potential genotoxic effects on larvae were investigated by the comet assay on blood cells, but this test did not demonstrate any significant DNA damage on larvae exposed to copper. This study confirms the adverse effects of copper on early life stages of rainbow trout even at the lowest environmentally relevant tested concentration.
