How specific are the scent lures How do fish species differ in their responses (In our experience, some species such as brown bullhead entered all traps, regardless of whether they were scented or not. Others, such as rock bass and yellow perch, were caught only in scented traps, but were attracted to both trout-scented and pumpkinseed-scented traps equally.)... 

In the La Cloche Mountain area of Ontario, 24% of lakes surveyed have no fish at all. 56% of these fishless lakes are known to have suffered a reduction in fish species composition. Small-mouth bass, walleye, white suckers, norther pike, lake trout, lake herring, perch and rock bass have been affected. 

Evidence for the existence of a natural source of tetraalkyllead compounds comes from analysis of air from the open sea, from coastal, and from estuarine areas, since 1 to 30 ng/m tetraalkyllead was observed [61] further evidence was found from abnormally high alkyllead to total lead ratios, which have been observed in atmospheric samples in Morecambe Bay, U.K. [60]. It was speculated that these tetraalkyllead emissions arise from methylation of lead compounds in coastal and estuarine intertidal areas [61]. The hypothesis of a natural source was supported by additional measurements [132, 174] see also [46, 133, 134]. However, according to recent results on transformation rates and lifetime of alkyllead species in the atmosphere it is not necessary to invoke the hypothesis of the natural alkylation of lead to explain the enhanced alkyllead to total lead ratios [182]. Also no indication of a large-scale natural source for tetraalkyllead compounds was found in other work [22], and determination of atmospheric content of tetraalkyllead compounds gave no indication for the occurrence of natural methylation processes of lead(ll) compounds [23] see also [48, 69, 70, 73]. The origin of trialkyllead species in rural pigeons (Columba livia) was associated in part with natural sources of tetraalkyllead in the environment [135], and also the presence of small amounts of Pb(CH3)4 in fish (Coho Salmon, Yellow Perch, Sucker, Rock Bass, Sunfish) from various lakes and rivers in Ontario, Canada, was taken as an indication for the possibility of environmental methylation or in vivo methylation of lead in fish [95] see also [93]. It was considered conceivable that bacteria in fish intestines or in fish tissue could methylate lead compounds [93, 94, 101, 178].

Bass and Mescal Limestone should not have been similarly depleted by this mechanism. Second, an evaporitic depositional environment would result in compensating trends of 0-enriched water and anomalously high local temperature that might effectively cancel each other. For example, the cherts from Lake Magadi, which have OsMow values ranging up to +44%c, are among the most 0-enriched of all terrestrial sedimentary rocks even though they formed in an evaporitic environment (O Neil and Hay, 1973).
