“…The differences in catch rate value previously mentioned reflect a greater similarity between the recreational and the competition fishing in the South and Southwest of Portugal, which is higher compared with the values found by Rangel and Erzini (2007) for the north. Compared with this study, the difference might be due to the generally higher fishing success of anglers participating in competitions (Brouwer andBuxton 2002, Pradervand andBaird 2002), while in the study of Veiga et al (2010) it might be related to the kind of habitat, beaches and cliffs, whereas in Rangel and Erzini (2007) only beaches were fished. The mean number of beach angling competitions increased from 2 in 1996 to more than 40 in 2007 (Fig.…”

Guerreiro A.I., Veiga P., Erzini K. 2011. Catches of the sport fishing competitions along the Algarve Coast (Portugal): species, sizes, catch rates, and trends. Acta Ichthyol. Piscat. 41 (3): 165-169.Background. Stocks of many marine fishes are in decline and a number of studies suggest that for some species the impact of recreational angling may be important. To date, only recreational (leisure) fishing surveys have been conducted in Portugal, with no studies on beach angling competitions, dynamically increasing in number over the past 10 to 20 years. In view of the above, we decided to evaluate the impact of such events on the Algarve coast (southern Portugal) in terms of the abundance, diversity, and respective weight of fish species caught and outline some conservation measures and recommendations for the management of the targeted species. Materials and methods. Participants of 22 angling competitions taking place between February and June 2007 were surveyed. In each competition a random sample of anglers was interviewed, and the specimens caught by each participant were identified, weighed, and measured.Results. Thirteen taxa belonging to eight families were identified, and the most common were: garfish, Belone belone (Linnaeus, 1761); mullets, Mugilidae (not identified); and mackerels, Scomber spp. A total of 563 specimens were sampled, totalling 75.4 kg of weight, with the average catch per angler weighing 0.5 ± 0.05 SE (n = 153) kg. Differences were also observed between the length at first maturity (L 50 ) of the specimens caught and their respective Minimum Landing Size (MLS) and Allowed Minimum Size (AMS), most particularly in the case of the European seabass, Dicentrarchus labrax (L.), with almost all individuals caught measuring below the speciesspecific L 50 . Analysis of time series of competition results (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) showed no evidence of a decrease in catches or in mean weight. Conclusion.Based on the results we propose that the AMS for beach angling competitions should be increased to the MLS in order to prevent the capture of juvenile fishes, especially the sea bass. Future studies should address the size selectivity of the hooks used in beach competitions, with a view to the implementation of a minimum hook size for competitions.

“…This trend differs considerably from that of the Eastern Cape estuarine linefishery, in which whites constituted > 70% of anglers and Indians < 0.3% (Baird et al 1996, Pradervand andBaird 2002). The majority of shore-based anglers used rods, and they fished mostly with bait.…”

“…The majority of shore-based anglers used rods, and they fished mostly with bait. This is similar to the Eastern Cape estuarine linefishery, where rod-fishing with bait is also the most popular form of shore-based fishing (Baird et al 1996, Pradervand andBaird 2002).…”

“…The majority (80%) of angling effort in the harbour and all the effort in the Mgeni Estuary stemmed from shore-based anglers. The importance of shore-based anglers in the estuarine linefishery has previously been unrecognized, with the exception of Pradervand and Baird (2002), who showed shoreanglers accounted for up to 59% of angling effort in some Eastern Cape estuaries. Accessibility to the estuary shoreline, as well as factors such as local regulations and the economic status of participants, appear to be important criteria determining the shore-angler to boat-angler ratio in an estuarine fishery.…”

“…There is limited information on the linefishery for some of the larger estuarine systems in the Eastern Cape and KwaZulu-Natal (Marais and Baird 1980, Guastella 1994, Baird et al 1996, James et al 2001, Pradervand and Baird 2002, Mann et al 2002. Those studies focussed primarily on the determination of catch, with little attention being given to the quantification of angling effort, socio-economics or anglers' attitudes towards fishery regulations.…”
