“…Growth factors and local lake chemistry were much more important in explaining mercury variation. Lake acidity can be inversely related to Hg concentrations in fish of adjacent lakes [32].…”

We analyzed a New York (USA) state database of mercury concentrations in muscle tissue for five species of fish (striped bass, yellow perch, largemouth bass, smallmouth bass, and carp) over a range of locations in the Hudson River (USA) between 1970 and 2004. We used regression models to discern temporal and geographic change in the fish while controlling for a positive correlation between mercury concentration and body mass. Mercury concentrations significantly increased in fish from New York Harbor waters to the mid-Hudson River. Striped bass and yellow perch showed a shallower increase in mercury concentration with river mile than did carp, largemouth bass, and smallmouth bass. Mercury concentrations declined over the 34-year period. These results imply that a geographically restricted source of mercury may be spread throughout the watershed by toxin-laden dispersing species. The increase of mercury toward the north may relate to a point source in the mid-Hudson River, or it may indicate mercury released from the Adirondack watershed. The decline of mercury over three decades corresponds to a reduction of various inputs in the region. The temporal and geographic pattern of mercury in sediments corresponds to the geographic trend of mercury in fish.

“…Even background levels of mercury can result in significant mercury bioaccumulation in fishes. A recent study of 24 ‘clean’ Massachusetts' waterbodies found wet mass muscle mercury concentrations of 0·15 mg kg −1 in brown bullheads Ameiurus nebulosus (Lesueur), 0·31 mg kg −1 in yellow perch Perca flavescens (Mitchill) and 0·39 mg kg −1 in largemouth bass Micropterus salmoides (Lacepède) (Rose et al ., 1999). The concentrations of mercury causing shortening of flagella and increased sperm head lengths, widths and areas in this study are therefore comparable to bioaccumulated mercury levels in wild and laboratory‐exposed fishes.…”

This study is the first to examine the morphology of fish sperm using automated sperm morphology analysis (ASMA). The technique was applied to investigate the effect of an environmental pollutant, mercury, on the sperm morphology of goldfish Carassius auratus, and the effects on sperm morphology were compared with those on sperm motility. Goldfish sperm flagellar length was significantly shortened after instant exposure to 100 mg l−1 (368 µM) mercuric chloride, while curvilinear velocity (VCL) and the percentage of motile sperm were significantly decreased at mercuric chloride concentrations of 1 and 10 mg l−1 (3·68 and 36·8 µM), respectively. After 24 h exposure to 0·001 mg l−1 (0·0037 µM) mercuric chloride, flagellar length was significantly reduced in 38% of the spermatozoa. Following exposure to 0·1 mg l−1 (0·37 µM) mercuric chloride for 24 h, however, the majority of spermatozoa (98%), had significantly shortened flagella and increased sperm head length, width and area. Sperm motility was also significantly decreased at 0·1 mg l−1 (0·37 µM) mercuric chloride, probably due to the significantly reduced flagellar length at this concentration. This study shows that the morphological examination of fish sperm by ASMA provides, not only, an excellent tool for monitoring reproductive disruption caused by environmental pollution, but also has applications to other areas of fish reproductive biology, such as cryopreservation and aquaculture.

“…Control fish had between .1 and .012 ppm, levels typical in fish collected from non-polluted environments lacking conditions which promote metal bioavailability, i.e. low pH and warm temperature (Wiener and Spry, 1996;Rose, et al, 1999). In aquatic systems that have natural mercury deposits or conditions favorable to availability, levels similar to those found in T1 would not be uncommon.…”

Fathead minnows (Pimephales promelas) were exposed to mercury (1.69, 6.79, and 13. 57 microg/L HgCl(2), 10 days exposure), and afterward their foraging ability was tested in a vegetated habitat for 7 days. Among the foraging metrics used were foraging efficiency, capture speed, and the ability to learn and retain information regarding habitat characteristics. In addition to behavioral tests, muscle tissue acetylcholinesterase activity and brain levels of several neurotransmitters were investigated. Comparisons with control fish and fish from the two highest exposure groups revealed consistent performance deficits in foraging efficiency and capture speed. However, no treatment effects on learning were detected, nor were differences in neurotransmitter levels detected. In determining the underlying proximate cause of the foraging deficits, it is believed that the greater pause time exhibited by treatment fish while foraging was the main cause of treatment differences. In the future, behavioral studies will continue to allow toxicity testing of environmentally relevant variables such as those used by behavioral ecologists.
