Fishing Effort and Associated Catch per Unit Effort for Small-Scale Fisheries in the Mozambique Channel Region: 1950–2016

Frontiers in Marine Science, 2021
The Mozambique Channel region in East Africa has diverse marine ecosystems and serves as a migratory corridor for economically important species. Local and foreign industrial fisheries operate in the Mozambique Channel, but regional small-scale fisheries

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.

Estimation Pendugaan CPUE (Catch Per Unit Effort) dan Potensi Maksimum Lestari Ikan Lemuru (Sardinella lemuru) yang Didaratkan di PPN Pengambengan, Jembrana-Bali

Journal of Marine and Aquatic Sciences, 2023
Lemuru is one of the highest catches landed in PPN Pengambengan. PPN Pengambengan is a strategic fishery port owned by Jembrana with a function as a center or center for marine fisheries landing. Improvement of fishing technology will be related to the problem of abundance or availability of fishery resoure stocks, so it is necessary to study CPUE, MSY

Comparison of Two Methods of Combining Catch-Per-Unit-Effort Data from Geographic Regions

, 1982
We examined two methods of combining catch-and-effort data from small geographic regions into large regulatory areas to estimate catch-per-unit-effort (CPUE): (1) weighting regional CPUE by bottom area occupied by the population; (2) weighting by ...

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.

Mean catch per unit effort and 95% confidence intervals.

, 2015
Mean catch per unit effort (CPUE) was modeled for nine area strata using a negative binomial model CPUE ~ month x area. CPUE is the number of legal-sized fish caught per vessel-day fishing effort.

Effects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery

Fisheries Oceanography, EarlyView.
ABSTRACT Global climate change is intensifying ocean deoxygenation, particularly in eastern boundary current systems such as the California Current. This study investigates the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast.

Large differences in catch per unit of effort between two minnow trap models [PDF]

, 2013
Background Little is known about variation in catch per unit of effort (CPUE) in stickleback fisheries, or the factors explaining this variation. We investigated how nine-spined stickleback (Pungitius pungitius) CPUE was influenced by trap model by ...

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 ...
