“…However, increased northern pike size structure was associated with increased measures of productivity. Although other studies have suggested that increased chlorophyll a is linked to increased growth (i.e., spotted bass Micropterus punctulatus; DiCenzo et al 1995) or fish yield (Jones and Hoyer 1982), findings of our study and in Paukert et al (2002b) suggest fish populations may not be strongly related to their physicochemical environment in the Nebraska Sandhill lakes. This may partially be due to the limited range for many of the physicochemical variables sampled in these lakes (Paukert and Willis 2000) Northern pike population characteristics were linked to emergent or submergent vegetation coverage.…”

Northern pike Esox lucius were sampled in Nebraska's Sandhill lakes during 1998 and 1999 to determine population characteristics and their influence on the fish community in these shallow, warm lakes at the southwestern edge of this species' natural range. Density‐dependent growth, size structure, and condition were not evident in the northern pike populations sampled. Relative abundance of largemouth bass Micropterus salmoides was positively related to size structure of yellow perch Perca flavescens and bluegills Lepomis macrochirus when northen pike were absent. When northern pike and largemouth bass populations were sympatric, these relationships were less evident. Population size structure of yellow perch was lower in lakes with northern pike, but decreased size structure was not evident for bluegills. Northern pike growth decreased with July bottom water temperature, which ranged from 20°C to 25°C. Recruitment patterns of northern pike in the Sandhill lakes appeared to be lake‐specific, strong and weak year‐classes occurring in the same year among different populations. Northern pike in these shallow, warm lakes act as a top‐down predator and appear to structure fish communities predominated by largemouth bass and panfish. Biologists managing warmwater Midwestern lakes thus should consider the effect of northern pike on fish communities.

“…Although black bass relative weights were relatively low (79-84), these were typical of black bass relative weights in low productivity systems such as Lewis Smith Lake (DiCenzo et al 1995;Maceina et al 1996). Striped bass relative weights varied greatly over the year, and lower body condition in summer and early fall was probably due to thermal stress (Bettoli 2005).…”

Introductions of striped bass Morone saxatilis into U.S. reservoirs have caused concern among anglers that target other species owing to the perception that this predator reduces the number of other sport fish and can limit available prey supplies. Recently, this controversy arose in Lewis Smith Lake (8,583 ha), Alabama, prompting this study to examine the effects of stocking striped bass on the resident population of black bass Micropterus spp. From October 2006 to August 2007, the diets of striped bass, largemouth bass M. salmoides, and spotted bass M. punctulatus were examined in this reservoir. The density and biomass of striped bass and black bass were computed from estimates of age‐0 black bass abundance, striped bass stocking rates, growth, and survival. Bioenergetics models were used to estimate striped bass and black bass consumptive food demands. Striped bass diets (by weight) were dominated by shad Dorosoma spp. (64%), followed by crayfish Oronectes spp. (12%), while black bass and sunfish Lepomis and crappies Pomoxis spp. comprised 5% and 6% of the diet, respectively. Numerically, sunfish–crappies and black bass only comprised 0.28% and 0.16% of the diets of striped bass. The diets of largemouth bass and spotted bass (by weight) were dominated by crayfish (72% and 75%, respectively) and sunfish–crappies (21% and 9%, respectively), while shad comprised 6% and 14% of the diets, respectively. Diet overlap values between striped bass and black bass were generally low but varied seasonally among species. The highest overlap between the diets of striped bass and black bass was observed in April and June. However, the relative weights of black bass did not decline or the frequency of empty stomachs among these species did not increase during or after this time. Overall, consumptive prey demand was similar between striped bass and black bass. Bioenergetics modeling estimated striped bass consumption of shad, bass–sunfish–crappies, and crayfish averaging 14, 3, and 5 kg/ha, respectively, compared with 3, 6, and 16 kg/ha, respectively, for black bass. Shad consumption by striped bass and black bass (relative to the total annual supply) was within acceptable levels. Striped bass consumption of black bass was low, striped bass and black bass partitioned prey resources, and the temporal differences in maximum consumptive demand varied between black bass and striped bass. Thus, we found that the impact of striped bass stocking on the black bass population was minimal.

“…In addition to the influences of aquatic vegetation, changes in water quality have been correlated with sport fish abundance, biomass, and growth (Kautz 1982;Buynak et al 1991;DiCenzo et al 1995;Hoyer and Canfield 1996;Maceina et al 1996;Allen et al 1999). For example, Hoyer and Canfield (1996) found that growth of age-1 and age-2 largemouth bass was positively correlated with total phosphorus, chlorophyll a, and total organic nitrogen concentrations.…”

Relationships between environmental variables and sport fish population parameters were investigated for West Lake Tohopekaliga from 1983 to 2002. Through time, the lake has undergone a process of cultural oligotrophication as indicated by reductions in nutrient and chlorophyll‐a concentrations because of improvements in wastewater treatment and the establishment of hydrilla Hydrilla verticillata in the system. With this decline in trophic state, angler catch and catch rate increased for largemouth bass Micropterus salmoides, but harvest and harvest rate decreased for black crappie Pomoxis nigromaculatus. Furthermore, the angler base of the lake shifted almost exclusively to those fishing for largemouth bass. Although angling effort for largemouth bass has increased through time with reductions in trophic state, angling effort for black crappies and sunfish species Lepomis spp. has declined. The growth of largemouth bass less than age 5 has also declined since the late 1980s, and the proportion of memorable‐sized fish in electrofishing catches decreased with decreases in total phosphorus. Areal coverage of hydrilla varied dramatically throughout this 20‐year period, and angler catch rate of largemouth bass as well as angler harvest rate of black crappies were positively correlated with hydrilla coverage. We believe the current level of nutrients and intermediate levels of vegetation (20–40%) should be maintained to balance the needs of both the angling and nonangling communities and to maximize the economic potential of the lake.
