On the 14th of June, 2005, in the Danube side channel "Jojkic" (N 44?50'33.1??, E 20?27'46.1??) near Belgrade, we recorded the presence of A. melas, ranging in weight (W) from 11.2 g to 135.6 g, and standard length (Ls) from 70 mm to 173 mm. Specimens were obtained from professional fishermen, who caught them with gill nets, as well from sport fishermen using fishing roads. Also, on 28th of May, 2005, on the lake "Savsko jezero" (N 44?47'20.1??, E 20?24'54.6??), we collected two specimens with gill nets. They were held in an aquarium until the 20th of June, when they were analyzed. Their weight (W) was 48.8 g and 97.5 g, their standard length (Ls) 145 mm and 183 mm, respectively.

Fathead minnows (Pimephales promelas) and oligochaetes (Lumbriculus variegatus) were exposed in the laboratory to sediment samples from the lower Fox River/Green Bay, and their bioaccumulation of PCBs was compared with PCB concentrations in synoptic collections of fish (black bullhead, Ameiurus melas) and oligochaetes (primarily Limnodrilus sp.) from the field. Total PCBs and PCB homologues (expressed as lipid-normalized tissue concentrations/organic carbon-normalized sediment concentrations) were qualitatively and quantitatively similar in the laboratory-exposed and field-collected oligochaetes. PCB concentrations in A. melas generally were greater than in any of the other test species, due possibly to differences in exposure (e.g. biomagnification) compared with the other organisms. PCB concentrations in P. promelas were consistently smaller than in any of the other species investigated. These results indicate that, under the exposure regime used in this study, laboratory tests with L. variegatus can provide a reasonable quantitative estimate of the bioaccumulation of PCBs in field populations of oligochaetes. However, the use of P. promelas in laboratory sediment tests may result in significant underprediction of the exposure of indigenous benthic invertebrates and fishes to bioaccumulable contaminants.

There is increasing concern about the effect of underwater noise on fish due to rising levels of anthropogenic noise. We performed experiments on the black bullhead (Ameiurus melas), a species with known hearing specializations and located within the Laurentian Great Lakes where there is considerable commercial and recreational boat traffic. We tested and compared physiology (baseline cortisol), behaviour (activity, sheltering), and morphology (ciliary bundles of hair cells) of bullhead to boat noise. At 140 dB re 1 μPa (−54.84 dB re 1 m·s−2), we saw clear behavioural effects in terms of both activity and sheltering levels despite no obvious morphological or physiological stress. Following both short- and long-period acute exposure to higher — but environmentally relevant — noise levels, bullhead were less active and sheltered more and also exhibited a decrease in ciliary bundles. These results suggest that there are sublethal effects of anthropogenic noise on fish behaviour and ciliary bundles, which may have direct implications on population health. Moreover, commonly used metrics such as stress hormones may not always offer the most relevant biomarker of the response to anthropogenic boat noise.

AbstractThe study on the external morphology of the non-native black bullhead (Ameiurus melas) was carried out on a population from Slovakia, based on triple regression and geometrical analysis. The breakpoints distribution in distance-based morphometric characters indicated that black bullhead reached its definitive phenotype early in ontogeny. Ontogenetic changes in external morphology occurred continuously throughout the whole size-range of the sample examined, and inter-individual morphological variation was very low. Such uniformity may reflect the possible founder effect and/or little phenotypic plasticity of this non-native population. No sexual dimorphism was observed. This is the first detailed study on external morphology of the species, and as such it contributes to the assessment of phenotypic plasticity and/or overall morphological variability of black bullhead’s invasive populations.
