  • About the Edition

    In 1997, estimated abundance of northern pike esox lucius within Harding Lake was 1,780 fish (SE = 323) for northern pike 300 mm FL, 1,415 fish (SE = 257) for northern pike 450 mm FL, and 246 fish (SE = 45) for northern pike 625 mm FL. Estimated density of northern pike 300 mm FL was 1.78 (SE = 0.32) fish per hectare. The estimated proportion was 0.21 (SE = 0.05) for northern pike from 300 to 449 mm FL; 0.66 (SE = 0.09) for northern pike from 450 to 624 mm FL; and, 0.14 (SE = 0.05) for northern pike 625 mm FL. In 1997, estimated recruitment (abundance of age-5 fish) was 377 northern pike (SE = 68). Estimated abundance was 421 fish (SE = 76) for northern pike < age-5 and 982 fish (SE = 180) for northern pike > age-5. The mean error in assigning the proper incremental age from the scales of 89 northern pike recaptured in 1997 from 1996 was -0.72 years (Z = 5.11; P 0.01); -0.13 years (Z = 0.39; P=0.69) for 16 northern pike that were age-4 in 1996; and -0.85 years (Z = 5.52; P0.01) for 73 northern pike age-5 in 1996. The estimated average percent error of the scale reader in reproducing the same age twice from a Harding Lake northern pike scale in 1997 was 3.2%. For Harding Lake northern pike, indirect value for maximum sustainable yield was estimated as 484 fish, number of northern pike needed to produce maximum sustainable yield was estimated as 1,626 spawning size fish, and the carrying capacity of Harding Lake was estimated as 3,251 northern pike age-5.

    Considerable information on distribution, abundance, life history, general ecology, and effects of impacts is available for brook trout from the area (MacDonnell and Bernhardt ). Lesser information is available for lake sturgeon, lake cisco, lake whitefish, white sucker, longnose sucker, and northern pike. Berg, S., E. Jeppesen & M.

      In a comparison for the entire Baltic Sea, the combined consumption by predators is in the same range as the fishery catch for 7 of 12 fish species (salmon, sea trout, eel (Anguilla anguilla), perch, northern pike, pikeperch, and whitefish, Figure 2). To evaluate if this implies resource competition, other factors and data need to be considered. Most (58 of 69) species, including northern pike, walleye, sauger, yellow perch, lake whitefish, lake trout, brook trout, smallmouth bass, and white sucker, are dispersed throughout the subcatchment. A few species, such as longear sunfish and green sunfish, are found only in Quetico Park and the Lake of the Woods region (Meredith and Houston.

In order to study how pike stocking affects trophic structure pike fingerlings (0– ha –1) were stocked during six years in eutrophic Lake Lyng (lake area 10 ha), uently, marked changes were recorded in the abundance of zooplanktivorous fish, catch per unit effort of roach, which was the dominant fish species, thus varied from 17 to   Northern pike.

We chose age 4 as the youngest age because mean length at age 4 was > in for all sexes (Table 13), so a high proportion of age-4 fish were of a size acceptable to anglers (there is no size limit for northern pike in the Cisco Lake Chain) at the beginning of fishing season.
