“…Oklahoma's record-breaking Paddlefish came at a time when many other game species, and especially trophy freshwater and marine species worldwide, have suffered a decline in age and size structure associated with overharvest and trophy targeting of the largest specimens (Shiffman et al 2014). The largest, most fecund fish may be removed from the population if the trophy fish are killed for record verification (Shiffman et al 2014(Shiffman et al , 2015. This removal has prompted calls for reducing or eliminating the mortality often associated with trophy fishing (Shiffman et al 2015).…”

“…The desire to reduce mortality of trophy fish provides a strong incentive to practice catch‐and‐release (Shiffman et al 2015; Bettoli et al 2019). Catch‐and‐release has been shown to be a viable approach to reducing unnecessary or undesirable mortality in Paddlefish (Scarnecchia and Stewart 1997; Cha and Melstrom 2018).…”

“…These results should be viewed with caution, as we did not include information on when these species were initially listed as threatened or how many ATRs have been submitted in all record categories since that time. Nevertheless, the fact that these species are currently threatened and can still be awarded an ATR might still incentivize anglers to catch the largest individuals in these threatened populations, limiting population resilience or recovery (Shiffman et al, 2015). A recommendation for further research is to unpick these trends between historical IUCN listings and IGFA records.…”

Shifts in the size and distribution of marine trophy fishing world records

The extensive nature of recreational angling makes it difficult to explore trends in global catches. However, trophy fishing world records may provide an insight into recreational fishing pressure on the largest species and size classes. Trophy fishing is promoted and recorded by the International Game Fish Association (IGFA), who manage an 80‐year database on the largest individuals of a species caught – called all‐tackle records (ATRs) – with information on the size and location of each record catch. We analyse these data to explore temporal trends in the size of record‐setting fishes, determine how past and present ATR catches are distributed globally, and examine trends in records for International Union for Conservation of Nature (IUCN) threatened species. The number of ATRs, and the number of species awarded an ATR, have increased significantly over the past 80 years. New records are for increasingly smaller maximum‐sized species of fish, with the average sized record shifting from 167.7 kg in the 1950s to 8.1 kg in the 2010s. ATRs for species listed as threatened (Vulnerable or higher) on the IUCN Red List have also declined by approximately 66% over the past two decades. Records were unevenly distributed around the world but have spread globally over time. Historically, ATRs were concentrated around the coastline of the USA but in recent decades more were reported in areas such as Japan and New Zealand. These data either reflect a shift away from mainly targeting large taxa to targeting a wider variety of smaller species, or that there are now limited larger specimens and so fewer ATRs are being set. Additionally, the scarcity of new records for threatened species appears to support IUCN assessments of their poor stock status. The spread of ATRs suggests a growing pressure on the largest size classes in regions with previously little trophy fishing pressure. We encourage the greater use of catch‐and‐release initiatives and mandatory data collection for all near records to better quantify trophy fishing pressure and ensure sustainable practices.

Shark recreational fisheries: Status, challenges, and research needs

For centuries, the primary manner in which humans have interacted with sharks has been fishing. A combination of their slow-growing nature and high usevalues have resulted in population declines for many species around the world, and to date the vast majority of fisheriesrelated work on sharks has focused on the commercial sector. Shark recreational fishing remains an overlooked area of research despite the fact that these practices are popular globally and could present challenges to their populations. Here we provide a topical overview of shark recreational fisheries, highlighting their history and current status. While recreational fishing can provide conservation benefits under certain circumstances, we focus our discourse on the relatively understudied, potentially detrimental impacts these activities may have on shark physiology, behavior, and fitness. We took this angle given the realized but potentially underestimated significance of recreational fishing for shark conservation management plans and stock assessments, in hopes of creating a dialogue around sustainability. We also present a series of broad and focused research questions and underpin areas of future research need to assist with the development of this emergent area of research.
