Several fish species, notably salmon, respond to the odors of their predators in an adaptive manner (Table 12.4). Coho and spring salmon retreated to the lower parts of a fish ladder when rinses of human hand, bear paw, dog meat, or sea lion meat were added to the water upstream. Even the odor of deer feet had the same effect (Brett and MacKinnon, 1954). L-Serine was identified as the active compound in mammalian skin (Idler etal, 1956). Arctic char, Salvelinus alpinus, also responds to L-serine from human hand wash, while D-serine and several other amino acids were not active. L-Serine is less active than the whole hand wash, suggesting that two or more compounds are required for the full response (Jones and Hara, 1982).

Between 1986 and 1988, levels of BDE-47, -99, and-100 were measured in whitefish (Coregonus spp.) from a remote mountain lake in Northern Sweden (Lake Storvindeln), Arctic char Salvelinus alpinus) from a heavily populated late (Lake Vattem) in south-central Sweden with numerous municipal and industrial point sources, and in trout (Salmo trutta] and pike (Esox lucius from several sites along Dalslands Canal in west central Sweden (Jansson et al. 1993). No point sources of PBDEs were identified from these sites. Whitefish from the remote lake contained the lowest levels (26 ng g lipid weight) of PBDEs, whereas the Arctic char, from a heavily populated lake, contained 520 ng/g lipid...

The presence of PFSAs (n = 4,6,8,10) and PFCAs (k = 7 to 15) were also investigated in sediment from three Lakes in the Canadian Arctic [166]. In Char and Amituk Lakes, total concentrations of PFSAs and PFCAs in sediment were approximately 5 and 7 ng/g dry weight respectively, while total concentration in Resolute Lake sediment was approximately 100 ng/g dry weight. In Char and Amituk Lakes, the XPFCAs were greater than the XPFSAs, while the opposite was true for Resolute Lake. The 8 2 and 10 2 FTUCAs were also observed in sediment samples from Char and Amituk Lakes.

According to Hultberg (1983), in Sweden after 1978 a great number of observations have shown that in the lakes fish population has disappeared or decreased year by year, mainly perch, trout, and evach. After heavy rainfalls (1972) when the pH of Lake Bredvatten went down to 4, all the perch population died although perch is the most resistant fish species. Other populations affected by low pH are arctic char, sea trout, atlantic salmon, brown trout, and crayfish.

Levels of biomagnification of highly chlorinated PCBs, of DDT, DDE, and chlordane-related compounds were disturbingly high, and all of these compounds together with a-hexachloro[aaaaee] cyclohexane have been identified in the diet of Inuit who consume and are essentially dependent on the harvest of ring seal, beluga, eider, and arctic char (Cameron and Weis 1993). The more controversial issue of the risks as opposed to the benefits of such consumption has been addressed (Kinloch et al. 1992). 

Due to limitations in nutrients and small lake size, the average species number is low. The total number of fish species found in Swedish lakes is around 50, but the number of species in a normal lake varies from about 14 in southern Sweden to 1, arctic char or brown trout, in the most northern parts. Some lakes in the alpine region are naturally fishless, since fish have not been reintroduced since the ice age. 

To understand and evaluate the distribution and availability of organic substances and metals, fish are collected from 32 lake sites and taken to a specimen bank. Some of these fish sampling stations have been run continuously since 1964, but others are more recent. The species normally used are perch and arctic char, and in a few cases pike and roach. The sites for specimen banking are, with two exceptions, situated at stations for reference or trend monitoring to get information from supporting parameters. A...

Houde et al. [59] found higher concentrations of SCCPs in lake trout (Salvelinus namaycush) from northern Lake Michigan (123 35 ng/g ww) than Lake Ontario (34 37 ng/g ww) however, MCCPs were higher in Lake Ontario lake trout (24 26 vs. 5.6 4.8 ng/g). Similar to observations for arctic char in Lake Ellasj0en, SCCP-MCCPs in Lake Ontario lake trout were much lower (50 x) than PCBs in the same fish [47].
