“…Alternatively, high abundances of bullheads in many systems could be the result of reduced water quality due to an increase in external nutrient loading. Bullheads appear to be adapted to a wide range of environmental conditions and may thrive in turbid, warm waters that are not conducive to many other fish species (Stuber 1982;Mork et al 2009). Hence, bullheads may not be the primary ecological driver that shifts a lake to the more turbid, algae-dominated state; rather, reductions in other, less tolerant fish species may allow for bullheads to increase in abundance, which is likely the case for Crane and Pickerel lakes, where dissolved oxygen issues have persisted in the past.…”

Bullheads Ameiurus spp. are found throughout much of the United States and are infrequently studied species. Although limited information has been published on the Black Bullhead A. melas and Yellow Bullhead A. natalis, it has been shown that bullheads can dominate the fish biomass in some north temperate U.S. lakes, resulting in a fish community exclusive of Walleye Sander vitreus and Yellow Perch Perca flavescens. Recently, recruitment and abundances of popular coolwater sport fishes, such as Walleye and Yellow Perch, have been declining in some northern Wisconsin lakes. These observed declines, coupled with high bullhead densities, led fisheries biologists to conduct whole‐lake bullhead removals on four northern Wisconsin lakes. Removal of Black and Yellow bullheads from these lakes resulted in substantial changes in the fish communities. The CPUE of naturally reproduced age‐0 Walleye increased in Lake Metonga and Patten Lake following the removal of bullheads. Additionally, survival of stocked Walleye increased in Crane and Pickerel lakes after bullhead removals, resulting in higher CPUE of age‐0 and age‐1 Walleye. Subsequently, adult Walleye abundance has increased or remained steady in all bullhead removal lakes. Significant declines in abundance of Bluegill Lepomis macrochirus and increases in abundance of Yellow Perch and Black Crappie Pomoxis nigromaculatus were also observed after bullhead removals, further illustrating a shift in fish community composition. Our observations suggest that when at high densities, bullheads can play a significant role in structuring fish communities and the removal of bullheads can increase recruitment, survival, and abundance of sport fishes like Walleye and Yellow Perch.

“…Whereas estimated CPUE for Lake Sava black bullhead fluctuated during the summer and autumn of 2009, 2010 and 2012, there was a significant and uniform decline in CPUE over 2011. Data on CPUE reported for other water bodies, such as the Corbara Reservoir in Italy (Pedicillo et al., ) and native populations in North America (Brown, Willis & Blackwell, ; Mork, Bisping, Fisher & Quist, ; Phelps, Ward, Paukert, Chipps & Willis, ) cannot be compared directly with the results from Lake Sava due to the different sampling methodologies used.…”

The life‐history traits and population dynamics of the black bullhead Ameiurus melas (Rafinesque) were studied monthly from August 2009 to December 2012 in Lake Sava in Belgrade (Serbia). This period included a mass mortality event in May 2011 and subsequent population recovery during 2012. Available evidence suggests the mass mortality was caused by European catfish virus that only affected the black bullhead. Changes in key life‐history traits and the recovery potential (increase in catch‐per‐unit‐effort, doubling of young‐of‐the‐year to adult ratio, earlier maturation and increased fecundity) following the mass mortality event suggest population resilience typical of a recurring boom‐bust pattern and demonstrate the species’ capacity to recover rapidly and re‐establish following disturbance. Repeated systematic mass removals of both juveniles and adults (using fyke nets) will be required if future fishery management measures aimed at limiting the population size are to be effective.
