“…In the shore crab, Carcinus maenus, the recovery processes involved the cytological damage of the gill epithelium (Stentiford and Feist, 2005). A variety of acclamatory effects have also been documented in fish and lobster chronically exposed to sublethal levels of copper (Grosell et al, 1998;Maharajan et al, 2011Maharajan et al, , 2012aMaharajan et al, ,b, 2013Paruruckumani et al, 2015a,b).…”

Copper is a trace element necessary for the normal growth and metabolism of living organisms. If exceeds its limit it becomes pollutant and causes pathological effects. Asian sea bass (Lates calcarifer) was exposed to sublethal concentrations of copper for 28 days and histopathological alterations were noticed in the gill, liver, muscle and intestine. Epithelial necrosis, hypertrophy, rupture of gill epithelium and haemorrhage at primary lamellae were observed after 7 days of exposure. Lifting of epithelium, oedema and fusion of adjacent secondary lamellae were conspicuous at 28 days of exposure. The experimental liver tissue showed reduction in the size of hepatocytes, vacuolisation, and hypertrophy. The intestine displayed fused microvilli, sloughing of mucus membrane and swollen cells. Muscle bundles with severe oedema and their thickening and separation were more pronounced in sublethal treatment of copper in the muscle. Several histopathological changes observed in various fish organs would serve a useful purpose in evaluating the toxic effects of copper. The present study clearly demonstrated that all the treated body organs exhibited significant damage with response; amongst the body organs the liver is an important target organ for copper toxicity in L. calcarifer and this species could be possibly used as a model organism for toxicity studies.

Copper is one of the most toxic metals for marine organisms. Biochemical changes occurring in the metabolically active tissues of gills (GL), hepatopancreas (HP) and muscles (MU) of the juvenile lobster, Panulirus homarus homarus on exposure to two sub-lethal doses (9.55 and 19.1 µg l-1) of copper were studied for 28 days of exposure (DoE). Sub-lethal doses of copper significantly (P<0.05) altered the levels of the total protein (TP), carbohydrate (TC), and lipid contents (TL) in test lobsters. Percentage decrease in all biochemical components increased with the progressing DoE, irrespective of the exposure concentrations. The order of percent decrease in the concentrations of the TP, TC and TL in different tissues at the end of 28 DoE was found to be MU>HP>GL, HP>MU>GL and HP>MU>GL. Results of this study revealed that sub-lethal doses of copper significantly alter the proximate composition of major tissues, particularly the TP levels in the MU tissues and thereby reducing the nutritive value of this economically important spiny lobster.

“…This is due to the simultaneous decrease in oxygen consumption and metabolic data, leading to an energy imbalance that may have influenced net growth efficiency. Maharajan et al [110] detected cytogenic effects of Cu in lobster (Panulirus homarus) exposed to different concentrations of the cupric ion, reporting different types of chromosomal aberrations and suggesting that Cu interacts with the formation of the spindle, distorting normal karyology. High Cr concentrations can result in eating disorders, habitat changes, enzymatic activity inhibition, histopathological changes, reduced body resistance to pathogens and mortality [63].…”

Metals, many of which are potentially toxic, are present in the aquatic environment originated from both natural and anthropogenic sources. In these ecosystems, these elements are mostly deposited in the sediment, followed by water dissolution, potentially contaminating resident biota. Among several aquatic animals, crustaceans are considered excellent bioindicators, as they live in close contact with contaminated sediment. The accumulation of metal, whether they are classified as essential, when in excessive quantities or nonessential, not only cause damage to the health of these animals, but also to the man who consumes seafood. Among the main toxic elements to animal and human health are aluminum, arsenic, cadmium, chromium, copper, lead, mercury, nickel and silver. In this context, this systematic review aimed to investigate the dynamics of these metals in water, the main bioaccumulative tissues in crustaceans, the effects of these contaminants on animal and human health, and the regulatory limits for these metals worldwide. A total of 91 articles were selected for this review, and an additional 68 articles not found in the three assessed databases were considered essential and included, totaling 159 articles published between 2010 and 2020. Our results indicate that both chemical speciation and abiotic factors such as pH, oxygen and salinity in aquatic environments affect element bioavailability, dynamics, and toxicity. Among crustaceans, crabs are considered the main bioindicator biological system, with the hepatopancreas appearing as the main bioaccumulator organ. Studies indicate that exposure to these elements may result in nervous, respiratory, and reproductive system effects in both animals and humans. Finally, many studies indicate that the concentrations of these elements in crustaceans intended for human consumption exceed limits established by international organizations, both with regard to seafood metal contents and well as daily, weekly, or monthly intake limits set for humans, indicating consumer health risks.
