Analyses of CPUE from the four islands of the Tristan da Cunha group to examine effects of trip length and period of rest between trips on CPUE performance

, 2022
Cursory examination of CPUE data as well as anecdotal evidence from skippers and fishermen have suggested that two important mechanisms may be at play concerning the behavior of CPUE values over time.

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.

Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

Fisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Habitat Standardization of CPUE Indices: Research Needs [PDF]

, 2003
Habitat standardization for billfish CPUE offers a potentially useful alternative to the statistical procedures used in the past. However, most of the assumptions of the current habitatstandardization methodology remain untested and some are not ...

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.

Investigating the Dynamics of Sex‐Structured Stock Assessment Models Under Sexual Size Dimorphism

Fisheries Management and Ecology, EarlyView.
ABSTRACT The integration of separate sexes in stock assessment models represents an advancement towards more realistic modeling of interactions between fisheries and target species. However, increased model complexity can also introduce additional uncertainty into the modeling process.
