Special Issue Information

Dear Colleagues,

Marine recreational fishing (MRF) is an important leisure activity, generating significant economic and social benefits across the globe and contributing to an important proportion of fishery removals. Nevertheless, and despite the fact that data on MRF are required for the sustainable management of many fisheries, there is an important lack of scientific knowledge regarding this activity. In fact, the scientific community acknowledges that studies regarding ecological impacts and socioeconomic relevance, including governance issues of MRF, are still scarce.

This Special Issue aims at addressing some of the key problems related to marine recreational fisheries, contributing to improving scientific information and decision-making about this activity. Topics to be address include sampling surveys; innovative tools to address data collection on MRF; biology and physiology of caught/target fishes; invasive fishes and MRF; catch-and-release-related issues; the effect of climate change on MFR; ecological, biological, and socioeconomic impacts of MRF; stakeholder involvement and integration on MRF data collection and management; existing and innovative management and governance arrangements; and case studies aiming at analyzing the relevance of such fisheries in relation to ecological and socioeconomic sustainability.

Senior and younger researchers are encouraged to contribute with their insights to the topic. New technologies included in data collection methodologies and/or data analysis are also encouraged.

In particular, the scope of this Special Issue includes but is not limited to the following topics:

  • Emerging innovative tools and methodologies to data collection and management of MRF;
  • Addressing multidisciplinary MRF data collection and analysis;
  • Climate change and MRF;
  • MRF management and governance models;
  • Policy making regarding MRF and stakeholders integration;
  • Marine spatial planning and marine protected area arrangements regarding MRF;
  • Case studies to analyze MRF ecological and socioeconomic sustainability.

Citizen science platforms, social media and smart phone applications enable the collection of large amounts of georeferenced images. This provides a huge opportunity in biodiversity and ecological research, but also creates challenges for efficient data handling and processing. Recreational and small-scale fisheries is one of the fields that could be revolutionised by efficient, widely accessible and machine learning-based processing of georeferenced images. Most non-commercial inland and coastal fisheries are considered data poor and are rarely assessed, yet they provide multiple societal benefits and can have substantial ecological impacts. Given that large quantities of georeferenced fish images are being collected by fishers every day, artificial intelligence (AI) and computer vision applications offer a great opportunity to automate their analyses by providing species identification, and potentially also fish size estimation. This would deliver data needed for fisheries management and fisher engagement. To date, however, many AI image analysis applications in fisheries are focused on the commercial sector, limited to specific species or settings, and are not publicly available. In addition, using AI and computer vision tools often requires a strong background in programming. In this study, we aim to facilitate broader use of computer vision tools in fisheries and ecological research by compiling an open-source user friendly and modular framework for large-scale image storage, handling, annotation and automatic classification, using cost- and labour-efficient methodologies. The tool is based on TensorFlow Lite Model Maker library, and includes data augmentation and transfer learning techniques applied to different convolutional neural network models. We demonstrate the potential application of this framework using a small example dataset of fish images taken through a recreational fishing smartphone application. The framework presented here can be used to develop region-specific species identification models, which could potentially be combined into a larger hierarchical model. Full article

During 2019, Greece conducted a nationwide telephone survey in order to estimate the number of marine recreational fishers (MRF), to identify the main fishing methods, to estimate their effort, economic aspects of their activity and to evaluate certain perceptions of marine recreational fishing. MRF are estimated to be 7.93% of the country’s resident population. Three main fishing methods were identified, fishing from the shore, fishing by boat and spearfishing. It is estimated that Greek MRF carry out approximately 11,461,765 fishing trips/year, their total catch is 9350 t/year and the total yearly expenditure is 132,186,000 Euros. Marine recreational catches constitute one-third of the reported small scale coastal fisheries’ catches, with their main catches belonging to the Sparidae family. The majority of MRFs are aware of the rules and limits associated with their activity, however a significant percentage seems to ignore or deny their existence. The results of the study indicate the social and economic importance of the activity in Greece and clearly demonstrates the need for regular monitoring and field work in order to properly evaluate marine recreational fisheries and sustainably manage both the activity and fisheries resources in the country.

The archipelago of Madeira (Portugal) is one of the main European big game fishing locations, where the main target species is the blue marlin (Makaira nigricans). Catch data for these fish were used to analyze their presence over the years, estimate their average weights, and calculate annual fishing success rates. The results showed a marked seasonal effect, with higher average catch rates in summer (June–July), suggesting a migration from the equatorial waters they inhabit at the beginning of the year to northern areas when the waters become warmer. The influences of some environmental factors were analyzed using generalized additive models, and it was observed that the occurrence of blue marlin may be influenced by water temperature, wind, rain, and atmospheric pressure. This fishery did not register a high mortality rate in blue marlin specimens due to the usual practice of catch and release; individuals captured in this fishery can be used as a source of information that allows for follow-up on the status of the blue marlin population in the region.

One of the most relevant information gaps in worldwide fisheries is related to the origin and consequences of the gender gap. Recreational fisheries show a remarkable gender gap, which has been especially poorly addressed in the scientific literature. In 2021, the Spanish Working Group on Marine Recreational Fishing (MRF) developed a broad diagnosis on the participation of women in MRF and agreed on a roadmap to address negative impacts derived from the gender gap. The network experts concluded that there is an urgent need to include the gender gap in the agendas of scientists, fishery managers, policy-makers, stakeholder organizations, and civil society. There is a need to better understand the gender-related socio-ecological impacts of MRF to improve fisheries governance and to develop policies and initiatives that facilitate the full access of women to the benefits derived from the practice of MRF. Establishing economic incentives, increasing the visibility of female success references, developing fishing-related programs specifically designed for girls, and promoting the perception of MRF as a family leisure activity in contact with nature will increase women’s engagement.
