“…The most commonly cited causes for inadequate bluegili size structure include overharvest (Coble 1988, Drake et al 1997, Jacobson 2005, the influence of male social interactions (Drake et al 1997, Jennings et aI. 1997, Aday et al 2006, deficiency of an ample predator assemblage (Novinger and Legler 1978, Guy and Willis 1990, Tomcko and Pierce 2005, and resource availability (Swingle 1951, Gerking 1962, Aday et al 2006. Age and size at maturity can influence bluegill size structure and tend to be variable across geographic locations (Gross 1991, Drake et al 1997, Jennings et al 1997, Aday et al 2003and 2006 is available pertaining to the age and size at maturation of bluegill in southeastern South Dakota impoundments.…”

Both social and demographic factors can affect size structure of bluegill (Lepomis macrochirus) populations, but these two factors have not been assessed in South Dakota impoundments. We compared length and age at maturity of bluegill in four southeastern South Dakota impoundments (two with historically low size structure and two with historically high size structure and related bluegill growth patterns to size structure and relative abundance. Despite large differences in size structure and maximum observed total lengths among lakes, all males from three of four populations were mature by age 3, with the only exception being Lake Mitchell (high size structure population; 89% mature). Mean total length at 100% maturity was lower in the two low size structure populations, and bluegill in the two low size structure populations matured at a smaller length than in the two high size structure populations; however, at least 50% of males in all four systems reached sexual maturity by 140 mm in all years. Negative relationships between mean catch-per-unit-effort and both proportional size distribution (r2 =0.47) and proportional size distribution of preferred length fish (?=0.86) values for all populations indicated that density-dependence was likely in these systems. Indications of social influence on bluegili behavior were observed; however, density-dependence was likely more influential on size structure.

“…Food is a limiting factor , as the main drift of insects in the river is June to mid-July (Gibson and Galbraith , 1975), this has been observed in other species by several authors (Benson, 1953;Gerking, 1962 ;Logan, 1963). Temperature has been identified as a significant seasonal effect in many species (Wingfield, 1940;Fishe r and Elson, 1950 ;Fry, 1951;Swift, 1961) .…”

“…Individual taxa were dried in an oven for 24 hours at 70 0°C (Tebo, 1955;Gerking, 962;Thut, 1969) to a constant weight. For the molluscs, shells were first removed in o1% HCI (Gerking, 1962;Richards & Richards, 1965) before drying. After removal from the oven, dried material was placed in a dessicator until it reached ambient temperatures.…”

The macroinvertebrate communities of four flood control reservoirs in eastern Nebraska, differing in age and degree of eutrophy were investigated from Ekman grab samples. Generally, the longer a reservoir had been influenced by eutrophication the larger the standing crop in it. Chironomids, ceratopogonids. fingernail clams, and Hexagenia were important at various stages of eutrophication with Chironomus predominating in the most eutrophic reservoirs. Tubifex decreased with eutrophication as did Sphaerium simili while Sphaerium declive maintained its abundance and sometimes increased.The chironomids Chironomus, Coelotanypus, and Procladius, fingernail clams, and Tubifex were early colonizers in the newest reservoir and developed a total standing crop as large the first summer as in subsequent ones. However, its composition became more diverse with time. In one reservoir sampled yearround, the standing crop was largest in late fall or early winter and smallest during summer. The most accurate information on macro-invertebrate standing crops in lakes and reservoirs comes from data collected on a year-round basis.
