“…However, the choice of the measure of central tendency may not be the only source of bias in the estimation of MRF expenses, as revealed by the mean values estimated in other regions of Spain (Gordoa et al, 2004;Soliva, 2006;García-de-la-Fuente et al, 2020), which double the mean values estimated in this and previously mentioned studies. This might be related to the bias towards more active fishers generated by voluntary participation, which is known as avidity bias (e.g., Thomson, 1991;Teixeira et al, 2016). In general, annual trip-related expenditures per fisher can be expected to be proportional to the frequency of participation (Thomson, 1991).…”

This study analyses the costs of marine recreational activity in Spain for the main fishing modalities and provides a cost-effective economic indicator (CEI) for each of them. The activity costs of 4,999 fishers were collected through an online survey, along with other fishing information. The published results of this survey, catch rates and catch composition, have been used in this study. Daily expenses per fisher were estimated by dividing reported annual expenses by annual fishing days. The CEI was estimated as the ratio of the market value of one kilo of recreational catch to the cost of catching it. The CEI showed differences between modalities in all regions, but of varying magnitudes. It is concluded that the CEI could diagnose the risk level of evolving from recreational towards subsistence fishing. The higher the CEI, the more compensatory the activity and the greater the possibility of moving away from a purely recreational activity in adverse economic conditions.

The growth of marine recreational activities raises the issues of the current lack of knowledge on these activities and the information required to assess their potential impacts. Indeed, the monitoring of unrecorded activities is a great challenge, especially when basic information, such as the size of the population practicing the different activities, is unknown. In this paper, the experience of the monitoring of marine recreational fishing was used to carry out a diagnosis study to assess the cost-effectiveness of survey methods used in France between 2004 and 2012. Costs of alternative surveys were balanced with data quality, and particular attention was paid to potential biases. Results showed that the involvement of citizens through diary surveys could be a cost-effective option when the recruitment of participants complied with randomness and representativeness requirements. The outcomes of this study provide useful insights to help managers and decision makers implement monitoring schemes in similar contexts. Highlights ► Precise costs of the different types of survey are provided and compared. ► Accuracy of effort and catch rate estimates is poor for most surveys. ► Diary surveys with involvement of citizens were found particularly cost-effective. ► Recruitment of participants must ensure randomness and representativeness. ► Findings are relevant for future monitoring schemes in a variety of contexts.

“…We analysed charter fishery data in a similar manner to the commercial data, because it is reported as weight per species per year per region in logbooks. The recreational data we accessed through Qfish was collected through a phone call survey 40 . Data from surveys conducted in 2010 24 and 2013 41 were combined to represent the catch of coral-associated species by recreational fishing regions.…”

Dependency of Queensland and the Great Barrier Reef’s tropical fisheries on reef-associated fish

Coral reefs have been subject to mass coral bleaching, potentially causing rapid and widespread degradation of ecosystem services that depend on live coral cover, such as fisheries catch. Fisheries species in tropical waters associate with a wide range of habitats, so assessing the dependency of fisheries on coral reefs is important for guiding fishery responses to coral reef degradation. This study aimed to determine how fisheries catches associate with coral reefs in Queensland, Australia. Queensland’s largest fisheries did not target fish associated with reefs, but specific sectors, particularly aquarium fisheries and commercial fisheries in the mid to northern region had a high dependence on species that use coral reefs. Regions that had a greater relative area of coral reefs had higher catches of species that depend on live coral, suggesting that coral area could be used to predict the sensitivity of a jurisdiction’s fisheries to bleaching. Dynamic analysis of stock trends found that coral trout and red throat emperor, the two largest species by catch for the reef line fishery, were at risk of overfishing if habitat loss caused declines in stock productivity. Management of fisheries that are highly dependent on reefs may need to adapt to declining productivity, but further research to support ongoing reforms in Queensland’s fisheries is needed to quantitatively link reef degradation to stock production parameters is needed.
