Age, Growth, Length-Weight Relationship, Sex Ratio, and Food Habits of American Smelt, Osmerus mordax (Mitchill), from Gull Lake, Michigan

Abstract: American smelt were collected monthly for one year from a southern Michigan lake. The length frequency distribution indicated one race of smelt was present. Greatest growth in length occurred during the second year. The general length‐weight equation was: Log W = −5.0925 + 2.9539 Log L, where W = weight in grams, and L = total length in millimeters. The correlation coefficient (r) was 0.9954. Sex ratios indicated a differential mortality between the sexes; females predominated in age‐groups I to IV, and their … Show more

“…Adult smelt generally select the largest organisms available and the larger fish have a more complex diet than the smaller fish. Similar feeding behavior was observed among smelt in lakes Superior (Hale 1960), Huron (Baldwin 1948), Champlain (Green 1930), and Gull Lake, Michigan (Burbidge 1969).…”

“…As a result of the broad temperature regime favorable for smelt feeding and growth (Ferguson 1965), the smelt is able to feed throughout the year and at various water depths on a variety of food organisms, especially zooplankton supplemented seasonally by small fish and benthic invertebrates. Similar items of diet are commonly used by smelt in the Great Lakes (Kendall 1927: Schneberger 1936: Baldwin 1948: Hale 1960: Gordon 1961Anderson and Smith 1971) and in other inland waters (Greene 1930;Reif andTappa 1966: Rupp 1968;Burbidge 1969: Delisle 1969Lackey 1969). The diet of landlocked Arctic Smelt (O. mordax dentex) in the Rybinsk reservoir in Russia (Inanova et al 1970) also resembles that of freshwater Rainbow Smelt in Lake Simcoe.…”
