“…From this database a subset for which collection of species richness was the objective of the sampling was chosen. Thus, the time dimension had to be taken aside, pooling all observations together in a similar way as described by Sipponen & Muotka (1996). In the case of wider and deeper rivers, gill-netting was used in still waters and both gill-and drift-netting for running waters.…”

“…For the analyses, it was assumed therefore, a large spatio-temporal scale: a 10-year span as the time unit, and the whole Garonne basin as the spatial unit. Thus, the time dimension had to be taken aside, pooling all observations together in a similar way as described by Sipponen & Muotka (1996). Moreover, local repeated surveys on some sampling sites showed that both environmental features and fish assemblages did not dramatically vary along the 10-year sampling period (Bengen et al 1992;Mastrorillo 1997;Hutagalung 1998;Cattanéo et al 1999;Reyjol 2002;Aguilar Ibarra 2004;P.…”

Influence of Non-point Source Pollution on Riverine Fish Assemblages in South West France

2005

The relationship between non-point source pollution (NSP) and fish assemblages in the Garonne basin, SW France was studied. Two independent data sets were coupled, one containing 20 physico-chemical variables and another containing 40 fish species in 84 study sites. Species were classified in guilds according to their feeding habitat and their diet composition. The physico-chemical variables were log-transformed and standardized for a factor analysis in which they were grouped into four factors which accounted for 80% of the total variability. These were named according to factor loadings (i.e. a measure of the variance of a given variable) whose absolute values were larger than 0.5. Hence, the first factor (F1) was formed by variables linked to NSP, most notably by sodium, chloride, potassium, orthophosphates, nitrites and chemical oxygen demand. The second factor (F2) was related to alkalinity (i.e. bicarbonates, calcium, conductivity and pH). The third factor (F3) included oxygen saturation rate and dissolved oxygen, and F4 combined both temperature and flow. Factor scores (i.e. weighted sums of the original variables) were then introduced in stepwise multiple regression models as explanatory variables of log-transformed fish species richness of trophic guilds. The NSP factor was significant (p < 0.05) for the following models: benthic omnivores (r2 = 0.66), all species (r2 = 0.65), total benthic species (r2 = 0.63), total water-column species (r2 = 0.57), benthic invertivores (r2 = 0.32) and water-column invertivores (r2 = 0.16). The guilds for which NSP was not significant were water-column omnivores, water-column piscivores and benthic detritivores. Thus, there was evidence of an inversely proportional association, though not causation, of NSP with species richness of riverine fish trophic guilds on a large spatio-temporal scale. Fish assemblages may respond in different ways to NSP depending on their species composition, on the region and on the scale, and not only to physico-chemical properties of water.

“…Recreational fishing is a leisure activity enjoyed by countless people throughout the world (Sipponen & Muotka 1996; Ditton 2008; Arlinghaus & Cooke 2009). It has an economic value estimated in the hundreds of millions or even billions of dollars annually in some countries (e.g.…”

Patterns of change in angler participation and demographics were examined for the recreational Atlantic salmon, Salmo salar L., fishery in Newfoundland and Labrador, Canada. An analysis of a licence stub return system, 1994–2010, showed a significant decline in resident angler participation, but this was not consistent across all regions of the Province. Mean age of anglers increased significantly, varying from 39.0 years in 1994 to 46.5 years by 2010. In some regions, mean age rose by over 12 years since the mid‐1990s, reflecting a decline in the recruitment of younger anglers. The return rate of angler logs also declined over time and was found to vary by age, sex and area of angler residence. Women and older anglers, and those living in specific rural areas had a greater tendency to return a record of their catch history than men and younger anglers. Identified changes in participation and demographics, which can affect exploitation and ultimately abundance, could be used to develop management measures that would maximise both harvest and socio‐economic benefits to the varied users of the resource.
