Can Climate‐Induced Changes in Freshwater Game Fish Abundance Be Inferred From Digital Catch Log Data?

Fisheries Management and Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

ABSTRACT The growing popularity of digital catch logs may present a low‐cost opportunity to monitor climate change effects on the distribution and relative abundance game fishes over large spatial scales. We analyzed data from popular fishing app identify spatiotemporal trends in freshwater fish catches throughout contiguous United States during 2015–2021. Warm‐water species became more common than cool‐water many locations. Increases tended occur northern range boundaries or non‐native ranges, declines at southern boundaries. Although log can be biased results reflect alternative phenomena operating interacting similarly scales (e.g., cultural eutrophication, changes popularity), remains viable explanation. Future research should further explore as potential tool for monitoring responses other stressors longer time frames multiple

Soft plastic fishing lures as a potential source of chemical pollution - Chemical analyses, toxicological relevance, and anglers’ perspectives

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 946, P. 173884 - 173884

Soft plastic lures (SPLs) are commonly used artificial in recreational angling. Anglers regularly lose SPLs while fishing and there is little knowledge about the environmental impacts of lost SPLs. As with other items, contain phthalates persistent additives that may leach into water. In this study, 16 randomly chosen common models were analyzed for leaching persistent, water-soluble additives, including phthalates. The estrogenicity sample extracts from a subsample 10 was assessed using luciferase reporter gene bioassays. Over period 61 days, leached targeted dimethyl phthalate (DMP), diethyl (DEP), benzyl butyl (BBP) di-n-butyl (DnBP) at median detectable concentrations ranging ng/g BBP to 1001 DMP as well 45 mobile, toxic (PMT) additives.

Public Concern of Fishing and Conservation Under the ‘Ten‐Year Fishing Ban’ Policy: Implications to Action Planning for Riverine Cetaceans

ABSTRACT Illegal, unreported and unregulated (IUU) fishing is one of the major anthropogenic impacts threatening aquatic ecosystem functioning. In middle lower reaches Yangtze River (MLYR), effective mitigation measures for IUU are still absent, primarily due to gaps in prioritizing conservation actions limited enforcement capabilities. present study, keywords associated with public concern, resource endowments efforts on online platforms were searched analysed using entropy‐weighting method identify areas MLYR requiring immediate against fishing.

Assessing angler attitudes, fishing behavior, boatside handling, and release practices in the northeastern United States recreational fishery for Shortfin Mako and other pelagic sharks

North American Journal of Fisheries Management, Journal Year: 2025, Volume and Issue: unknown

Abstract Objective Recreational fishing for pelagic sharks is a popular activity off the northeastern United States. Recently, new regulations have been implemented in fishery response to overfished status of North Atlantic Shortfin Mako Isurus oxyrinchus stock, including hook restrictions, larger and sex-specific minimum retention sizes, ultimately full ban. Under these number retained Makos has decreased, but thousands continue be targeted by catch-and-release anglers or incidentally captured, there need better understand how ongoing practices may affect mortality stock recovery.

Drivers of Recreational Angler Satisfaction in Port Phillip Bay, Australia

ABSTRACT As a widely enjoyed pursuit, recreational fishing plays key socio‐economic role in Australia by supporting coastal businesses, especially regional areas. Satisfaction is considered an end outcome of angling that important fisheries management contributing to ongoing participation and regulatory strategies. Port Phillip Bay (PPB) Victoria, Australia, hosts the State's largest marine fishery, yet angler satisfaction has not been previously explored. We evaluated influence age groups, regions (5 boat ramps Melbourne, 7 Bellarine, 8 Mornington), target species (snapper, King George whiting, calamari, flathead), catch rate on spatiotemporal patterns long‐term from creel surveys conducted around PPB during 2016–2022. Angler varied with per unit effort (CPUE) avidity. annually regionally, higher among younger anglers, Bellarine region along western coastline PPB. also species, anglers targeting calamari being generally more satisfied, although increased for snapper when interacted CPUE. Insights into behavior factors will ultimately provide basis formulating performance indicators monitor assess future satisfaction. More broadly, our study provides guidance about how interventions impact satisfaction, therefore making it likely needs concerns fishers are decision processes.

On the Line and Online: Higher Non‐Response to Web‐Based Surveys Over‐Represents Avid Recreational Fishers Compared With Telephone Surveys

Fisheries Management and Ecology, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 31, 2024

ABSTRACT Recreational fishing surveys have an important role in providing data to inform fisheries management. The selection of a contact method is and often challenging consideration that influences the potential for non‐sampling errors can result unrepresentative biased estimates. Telephones are used many off‐site recreational surveys, but widespread use digital technology suggests online could be viable alternative. We compared phone with alternative using probability sampling from licence database. Response rates were lower (13%–26%) than (97%–98%). proportion respondents who reported marine previous 12 months did not differ between survey methods (98% both modes), avid fishers was higher (41%–54%) (37%–40%). These differences reflect respondent burden where self‐administered more likely opt‐out. Higher non‐response over‐representation may compromise reliability. recommend comparative studies quantify correct biases when evaluating modes new or ongoing surveys.

ABSTRACT Recreational fisheries are dynamic social‐ecological systems. Identification of anticipated future trends supports the design policies and management to deliver outcomes for resources, users, communities. To this end, we applied a forecasting method (i.e., Delphi survey) recreational in five Nordic countries. The survey consisted three rounds included 20 diverse experts from each country. study focused on expert perceptions angler behaviors linked specific angling activities (e.g., gear used, species targeted), more general behavior social media use, stewardship). Experts unanimously expected increases fly fishing, stewardship, use angling‐related technologies platforms upcoming decade.
