“…It should be noted that growth rates and lengths in females can be greater than in males (Hunt & Jones 1975). During these assessments, a total of 2358 sites of 100 m length were fished in 202 rivers across a 3-year cycle (i.e., each site was fished, on average, three times in the study period) using DC electric fishing (hand-held or boat-mounted) and seine netting (as appropriate for the habitat).…”

“…review of . Whilst there have been some studies completed on their life history traits, such as somatic growth rates (e.g., Hunt & Jones 1975;Lobón-Cerviá & Fernández-Delgado 1984;Przybylski et al 2004), this tends to be restricted to single river systems with scant information available on how their growth varies over larger spatial areas and the factors that influence this variability. In the UK, they are indigenous to eight eastflowing river catchments between the Yorkshire Ouse and River Thames (Wheeler & Jordan 1990), with nonindigenous populations now also present in a number of other rivers as range expansion has occurred as a result of introductions for angling (Wheeler & Jordan 1990).…”

The European barbel Barbus barbus is threatened in areas of its range because of its sensitivity to anthropogenic disturbance in riverine habitats and, in the UK, is indigenous to a relatively small number of eastflowing rivers, with nonindigenous populations present in other rivers following introductions for angling enhancement. Fish stock assessment surveys completed between 2002 and 2010 collated age and growth data from 20 rivers across their indigenous and nonindigenous UK range. Analyses revealed that individuals present in samples are of 21 years old, with growth rates highly variable between rivers. There was no relationship between growth rates and the maximum age of fish per river, and there was no difference in growth rates between their indigenous and nonindigenous ranges. A range of abiotic data were collated and analysed against the growth data; these analyses suggested higher mean growth rates were evident in rivers of higher biological water quality (expressed as British Monitoring Working Party Score) and higher mean air temperatures (used as a surrogate of water temperature). That growth of B. barbus was significantly and positively enhanced by increased biological water quality was in contrast to cyprinid fishes such as roach Rutilus rutilus and suggests that as river water quality continues to improve through reduced nutrient inputs, further ecological changes are likely in riverine fish communities.

“…The structuring of the population in groups of genetically related individuals may amplify, by sampling effect, small fluctuations of completely random origin. Unfortunately, the statistical analysis of the only study suggesting shoaling behaviour ( Hunt & Jones, 1974a) was not carried out in such a way as to answer this question unambiguously. However, in our fishing campaigns, we commonly observed that, in winter, individuals were clustered in the river, and clusters seemed to be composed of morphologically similar individuals.…”

Movements of adult fish in a hybrid zone revealed by microsatellite genetic analysis and capture‐recapture data

et al. 2000

Summary Barbus barbus and Barbus meridionalis (Cyprinidae) form a hybrid zone in the Lergue river (southern France). We attempted to characterise the pattern of adult dispersal with the aim of understanding the evolutionary interactions maintaining this hybrid zone. In a previous capture/recapture study, movements between localities at a distance of 2.5 km or more appeared extremely rare. We therefore decided to investigate adult movement using a different method, based on genetic markers. As this hybrid zone has produced allele frequency clines, massive population movements would produce temporal variations in genetic composition at a given locality. In order to determine the relationship between gene frequency and position, we surveyed four diagnostic or semidiagnostic microsatellite loci over the hybrid zone and estimated the cline produced by introgression. Then, we focused on a single locality at the centre of the hybrid zone and established its introgression index over 11 periods during two years. The introgression index varied between periods producing significant Fst. A synthetic hybrid index, based on principal component analysis of the logit frequencies, was used for regression analyses and appeared significantly correlated with the river flow. This may be explained by displacement of adult fishes in response to flow increase. Using the information from the cline, we estimate that the most important gene frequency changes among dates, if created exclusively by population movement, correspond to a distance of 1500 m. Additionally, we performed recaptures on a finer geographic scale than previously, around the central locality. No recaptured fishes were observed at 1875 m or more downstream, and at 875 m or more upstream, from the central locality. A high proportion of recaptured fishes (20% and 12%) was found in the nearest points (312 m downstream and 437 m upstream, respectively). Thus, we established that (i) individual movements appear limited to a few hundred metres and (ii) individuals in a location tend to move in the same direction at the same time, probably in response to the same environmental factor.

“…The difficulty of estimating the actual size offish populations in fresh waters remains an outstanding problem, particularly in large water bodies (Brown 1975;O'Hara 1981). Mark-recapture estimates are often time-consuming and have frequently produced results of dubious validity, especially when the underlying assumptions of the various models have not been fulfilled (Matthews 1971;Hunt & Jones 1974;Begon 1979). An alternative approach, and one which has found favour in water bodies where areas can be delineated and effectively closed, is that of a removal technique, using either a series of nettings or electrofishings to capture the fish.…”

Fish population estimation: the use of rotenone to evaluate the reliability of a removal technique

et al. 1985

View full text Add to dashboard Cite

Abstract. The use of a large‐meshed seine net (aperture 2–5 cm) in enclosed compounds was an effective method for the capture of large grass carp, Ctenopha‐ryngodon idella (Val.), and tench, Tinea tinea L., with mean fork lengths of 42–9 cm and 38–3 cm and mean weights of 1–53 kg and 1–10 kg respectively. Calculated population estimates using a constant‐effort removal technique showed a high degree of accuracy for grass carp, when the absolute index of population size was checked after completion of netting with an application of a commercially available rotenone formulation. It is suggested that this was so because of the large proportion (>90%) of the total population netted. Large tench may be unsusceptible to rotenone at the low concentration of 0–5 ppm used, so no check on the accuracy of the population estimation was possible.
