Life History of the Emerald Shiner in Lewis and Clark Lake, South Dakota

<p>The age, rate of growth, reproduction, feeding habits and population dynamics of the emerald shiner (Notropie atherinoides) were studied from 10, 375 fish collected in Lewis and Clark Lake South Dakota. The population consisted of four age groups dominated by young-of-the-yew during the summer and fall and by age group during spring and early summer. Age group II was common only in the spring and early summer. While age group III was rarely found. Average length at annulus formation was 66 mm for age group I and 84 mm for age group II. Females attained a size advantage over males after the first year. The spawning season extended from June through August. A rapid and precise method was devised for conducting food-habit determinations which could be analyzed statistically. Adult emerald shiners fed selectively on Daphnia. A gradual change in young-of- the-year food habits was evident; fish smaller than 40 mm fed primarily on algae whereas larger fish fed chiefly on cladocerane and copepods. Populations of emerald shiners were characterized by a fast turnover. Males had a higher mortality rate than females during their second and third years of life.</p>
