“…Some recreational anglers are members of angling clubs that are affiliated to the South African Sport Anglers and Casting Confederation (SASACC), an organisation which in 2016 represented 28 433 anglers (SASACC, 2016). Members of angling clubs often take part in angling tournaments (Taylor et al, 2015). As one of the aims of tournament angling is qualification for a place on a provincial or national team, members are guided by, and must adhere to, the constitution, policies, rules and regulations of SASACC and, importantly, report their tournament catch data to the local conservation departments.…”

Recreational angling is an important form of utilisation of inland fisheries in South Africa but there is little information on this sector. The objective of this study was to provide an assessment of recreational bank angling in the Free State Province using licence sale and tournament data. During 2013 and 2014, 8 256 and 7 710 angling licences were sold, respectively. This represents a decline of 76% compared to the total licence sales in the Province in 1971. Tournament catch and effort data were obtained for 4 796 tournaments that were held on 17 dams from 1974 to 2014. Reported tournament effort decreased by 67% from 8 548 tournament days in 1998 to 2 828 days in 2014. Tournament catch composition was dominated by alien common carp Cyprinus carpio. Overall, this species comprised 81% of the weight and 77% of the number of fish landed during tournaments making it the most important angling species. The recent observed increase in subsistence angling could not be included in the analysis as participants are mostly not licensed. Alternative methods are therefore required if total catch and effort are to be estimated.

“…In addition, back-calculated length can be used to evaluate fish growth over an entire life span and determine changes in growth due to life-history events and environmental stochasticity (Campana and Thorrold, 2000). Finally, age frequency in a representative sample is often used to convey mortality rate information using catch curve analysis (Taylor et al, 2015).…”

Age information derived from calcified structures is commonly used to estimate recruitment, growth, and mortality for fish populations. Validation of daily or annual marks on age structures is often assumed, presumably due to a lack of general knowledge concerning the status of age validation studies. Therefore, the current status of freshwater fish age validation studies was summarized to show where additional effort is needed, and increase the accessibility of validation studies to researchers. In total, 1351 original peer-reviewed articles were reviewed from freshwater systems that studied age in fish. Periodicity and age validation studies were found for 88 freshwater species comprising 21 fish families. The number of age validation studies has increased over the last 30 years following previous calls for more research; however, few species have validated structures spanning all life stages. In addition, few fishes of conservation concern have validated ageing structures. A prioritization framework, using a combination of eight characteristics, is offered to direct future age validation studies and close the validation information gap. Additional study, using the offered prioritization framework, and increased availability of published studies that incorporate uncertainty when presenting research results dealing with age information are needed.

“…Concomitant with their expanded distribution, tournament competitions for bass have become a global phenomenon, with premier angling events routinely fielding anglers from Central and South American, European, Asian, and African countries (Taylor et al. ). In southern Africa, for example, populations of Largemouth Bass were first established in the late 1920s (Harrison ; Hargrove et al.…”

Angling for adult black bass Micropterus spp. as they defend nests containing eggs or fry (i.e., bed‐fishing) has drawn concerns from fishery managers and anglers due to negative impacts on reproductive success. Research efforts, however, have failed to consider bed‐fishing scenarios other than male‐directed targeting, which may inaccurately reflect angler behaviors. To gain insights into the behaviors, motivations, and attitudes associated with bed‐fishing across a large extent of the global distribution of black bass, we surveyed tournament anglers from the southeastern United States and South Africa (where black bass were introduced in 1928). Responses from 440 black bass tournament anglers indicated that during the reproductive season nearly half of all anglers spent 50% or more of their time bed‐fishing and that larger, female fish were preferential targets. Overall, the responses from U.S. and South African anglers were very similar, but significant attitudinal differences were associated with the perceived impacts of bed‐fishing on adult reproduction and juvenile production. Our results suggest that there are commonalities among the preferences and behavior of anglers from disparate geographic regions, and we highlight the need for future research on the impacts of size‐ and sex‐selective bed‐fishing of basses.
