Using Catch Data to Estimate Changes in Global Commercial Abalone Abundance

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in global wild capture production of abalone are explored to infer potential changes in biological stocks. The study found that 77% (or 10 out of the 13) of the countries that reportedly caught abalone in the wild have experienced declines in catches between 1980 and 2023, and on aggregate catch declined by almost 83% between 1980 and ...

Current state of resources for japanese flying squid Todarodes pacificus in the northwestern Tatar Strait (Japan Sea)

Известия ТИНРО, 2020
Data on commercial catches of japanese flying squid Todarodes pacificus in the northwestern Tatar Strait in 2003–2019 are analyzed. To assess the resours status in the study area, the relative number (individuals per jigger winch per hour) and biomass ...

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Standardization of CPUE for walleye pollock in the Okhotsk Sea with inclusion of some environmental factors

Известия ТИНРО, 2020
Catch of walleye pollock by Russia is the highest in the northern Okhotsk Sea where on average 0.94 million metric tons were caught annually in the period between 1962 and 2017, or around 24 % of the total yield of Russian fishery.

Recovery of Four Commercial Fish Stocks in Lake IJsselmeer (The Netherlands) After Major Fishery Management Interventions

Fisheries Management and Ecology, EarlyView.
ABSTRACT Sustainable management of inland fisheries presents major challenges because it often involves complex and open access systems. Lake IJsselmeer is among the largest freshwater lakes in western Europe and supports active commercial fisheries.

Does Survey Angling CPUE Reflect Population Density of Northern Pike (Esox lucius) in Small Boreal Lakes?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Knowing the relationship between catch per unit effort (CPUE) and population density is crucial for the management of recreational fisheries. We conducted standardized angling for pike in 16 lakes (3.4–22.1 ha) to test whether lure type, color, and pike density affect CPUE and the size of captured fish.

Recreational Fisheries in Türkiye: Socio‐Economic Profiles, Technological Trends and Governance Challenges

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries in Türkiye constitute an understudied socio‐economic sector spanning marine and freshwater ecosystems across the Mediterranean and Black Sea basins, yet robust national participation estimates remain constrained by the absence of a comprehensive registry or probability‐based sampling frame.

Evidence of deterrence from patrol data: Trialling application of a differenced‐ CPUE metric

Conservation Science and Practice, 2022
Abstract Ranger‐led law enforcement patrols are the primary, site‐level response to – and the most common source of data on – illegal activity threatening wildlife in protected areas. Yet evidence that patrols effectively deter rule‐breaking is limited, and common management metrics for evaluating deterrence, which use ranger ...

A Fishery‐Dependent CPUE‐Based Proxy Index for Juvenile Japanese Anchovy (Engraulis japonicus) Recruitment Variability in Southeastern Korea: Associations With Lagged Climate‐Ocean Conditions

Fisheries Oceanography, EarlyView.
ABSTRACT We developed and evaluated a fishery‐dependent catch‐per‐unit‐effort (CPUE)‐based proxy index for juvenile Japanese anchovy (Engraulis japonicus) recruitment‐related variability in the southeastern coastal waters of Korea. The proxy was constructed from bimonthly CPUE of the smallest juvenile size class (20–40 mm) in the anchovy drag‐net ...
