“…It is well documented that Al-toxicity in various aquatic biota depends on changes in water physico-chemical conditions, rather than the presence or the concentration of a certain aluminium species [ 1 , 3 , 8 – 11 ]. Accordingly, it has been demonstrated that a non-steady state Al-chemistry often predominate in natural environments [ 12 – 15 ], in which monomeric Al-forms are transformed to polymeric Al-forms, may dictate the Al-toxicity [ 16 ]. When Al-solubility decreases as pH is elevated in an acidic water body, the toxicity to fish increases because aluminium starts to polymerise, and subsequently accumulates on the gill surface [ 10 , 16 ].…”

It is well known that aluminium is the principle toxicant killing fish in acidified freshwater systems, and it has been shown that crucian carp (Carassius carassius) can survive exposures to aqueous aluminium levels toxic to most other freshwater fish species. The crucian carp has a remarkable ability to survive anoxic conditions, and the aim of the present study was to reveal if the tolerance to aluminium can be associated with the ability to survive prolonged anoxia. Crucian carps were exposed to either acidic Al-rich water (pH 5.8; 960 μg Al/l), acidic Al-poor water (pH 5.8; 50 μg Al/l) or untreated control water (pH 6.5; 50 μg Al/l). Blood, muscle and gill samples were collected from exposed fish, and closed respirometry was performed to measure critical O2-tension an normoxic O2-consumption. The results show an increased gill surface area in Al-exposed fish, while the critical O2-tension did not change. The normoxic O2-consumption was lower in Al-exposed fish and might be due to a reduced metabolic rate. The results suggest that crucian carp exposed to aluminium do not become hypoxic, since haematocrit, plasma lactate and blood ethanol did not differ from that of control fish after 14 days of exposure. We also observed an initial loss of plasma chloride and sodium, followed by a stabilisation of these ions at a lower level than in control fish. The decrease in plasma ions caused a transient increase in haematocrit and water content in muscle tissue, returning to control levels when the ion concentrations stabilised, suggesting that the water balance was restored. We conclude that the high tolerance to aluminium in crucian carp is associated with its ability to avoid hypoxia as well as an ability to counteract a continuous loss of plasma ions.

“…In combination with a lowered dissolved O 2 -concentration, such accumulation might lead to hypoxia. Accordingly, it has been suggested that hypoxia is of major importance for the acute effect of acidic aluminium rich water, especially under unstable physico-chemical conditions (Neville 1985;Poléo et al 1994Poléo et al , 1995Witters et al 1996;Poléo & Bjerkely 2000). The idea that hypoxia is of importance, is also indicated by the results showing that the larger fish had the higher mortality.…”

“…For example, organic Hg (e.g. methyl-mercury) is more likely to accumulate and cause toxic effects to fish than the inorganic form (Boudou and Ribeyre, 1985), monomeric inorganic Al is more toxic than more polymerised forms, due to the greater capacity of monomeric inorganic Al to bind to gill surfaces and damage gill function (Poléo and Bjerkely, 2000;Alstad et al, 2005), Fe 2+ has greater toxicity to aquatic organisms than the Fe 3+ form, and at high concentrations, causes oxidative damage to cells and organs (Bury and Grosell, 2003;Chen et al, 2011).…”

Potential for biomonitoring metals and metalloids using fish condition and tissue analysis in an agricultural and coal mining region

Agricultural and mining activities contribute to metal inputs in freshwater ecosystems around the world, which can in turn bioaccumulate in biota such as fish. Monitoring of metals loads in biota thus provides insight into the concentrations of bioavailable metals within the environment. Little research has been conducted on the potential of Australian freshwater fish for biomonitoring metals. Within the Fitzroy Basin of Central Queensland, a major agricultural and coal mining region, three commonly-encountered fish taxa were analysed for tissue metal loads. Arsenic concentrations in Nematalosa erebi and Melanotaenia splendida splendida tissue were elevated (above Food Standards Australia and New Zealand (FSANZ) guidelines), with highest concentrations in N. erebi liver tissue (up to 5.14 μg/g). Lead concentrations were above the FSANZ guidelines in all three fish taxa analysed, with highest concentrations in Hypseleotrid full-body tissue (up to 5.99 μg/g). Selenium in M. s. splendida and N. erebi tissue was positively correlated with total selenium in water (p < 0.05; r = 0.68 and 0.87 respectively). Environmental boron, selenium and nickel concentrations were positively correlated with N. erebi liver tissue metals. N. erebi hepatosomatic index was negatively correlated with dissolved arsenic, manganese, and total phosphorus (in water). The results highlight that M. s. splendida and N. erebi yield bioindicators which are responsive to environmental metals, and thus have potential for use in biomonitoring metals. The two species are also widespread along the east coast of Australia, there is thus a strong potential for applying the results to other regions within Australia.
