Profil Populasi Tuna Madidihang (Thunnus albacares Bonnaerre, 1880) yang Tertangkap pada Perikanan Handline di Perairan Nusa Tenggara Timur dan sekitarnya

Jurnal Kelautan Tropis
Yellowfin tuna (Thunnus albacares) is the main target of capture fisheries in various tropical waters, including Indonesia, owing to its high economic value. Global market demand increases the rate of exploitation; therefore, the size of the catch is not

Sampling technique affects the population structure assessments of fiddler crab Minuca vocator (Herbst, 1804) (Ocypodidae: Gelasiminae)

Nauplius
We examined how the sampling technique can affect the evaluation of Minuca vocator (Herbst, 1804) population structure. We used two sampling procedures: catch-per-unit-effort (CPUE) and quadrat technique (QT).

Predicting unseen chub mackerel densities through spatiotemporal machine learning: Indications of potential hyperdepletion in catch-per-unit-effort due to fishing ground contraction

Ecological Informatics
In fisheries management, accurate estimates of fish stock abundances are crucial for sustainable harvesting practices. Traditional methods often rely on catch-per-unit-effort (CPUE) data, assuming fishing effort is uniformly distributed across the stock ...

A Study on the Impact of Environmental Factors on Chub Mackerel Scomber japonicus Fishing Grounds Based on a Linear Mixed Model

Fishes
Chub mackerel (Scomber japonicus) is a commercially important fish species which are widely distributed in the North Pacific. Based on the fishery data from China’s high-sea light-purse seine fishing from 2014 to 2020 and the marine environment factors ...

An overview of detailed CPUES and of fisheries indicators of the EU purse seiners in the Atlantic

, 2017
This paper has calculated several fishery indicators related to the fishing effort and various CPUEs of EU purse seiners in the Atlantic Ocean during the 1991-2015 period. This work has been done because these basic fishery indicators remain very useful to better understand many past and present changes in fisheries and tuna stocks.

Discriminación de variables ambientales que influencian la captura por unidad de esfuerzo: el caso de la pesquería de krill antártico Discrimination of environmental variables that influence the catch per unit effort: the case of the Antarctic krill fishery

Latin American Journal of Aquatic Research, 2011
Para emplear la captura por unidad de esfuerzo (CPUE) como índice de abundancia se debe realizar normalmente un proceso de estandarización que consiste en aislar desde las series de tiempo de CPUE todos aquellos efectos exógenos a las variaciones ...

Ulov po jedinici napora (CPUE) udičarenem na rijeci Dravi

, 2017
Cilj rada bio je odrediti stanje ribljeg stoka sportsko ribolovnim tehnikama udičarenja, njihovu kondiciju i CPUE. Istraživanje je provedeno na jednoj lokaciji na 149. riječnom kilometru rijeke Drave. U ribolovu su sudjelovala dva ribolovca podjednakog iskustva. Ulovljeno je 114 jedinki 13 vrsta riba, od kojih jedna alohtona vrsta.
