Time and spatial trends in landing per unit of effort as support to fisheries management in a multi-gear coastal fishery [PDF]

open access: yesPLOS ONE, 2021
Landings by the multi-gear coastal fleet operating off the Portuguese continental coast include about 300 species, from which only a few are the object of management plans. In this study, daily landings (kg trip-1) are used, along with an effort indicator, vessel length overall (LoA), to obtain landings per unit of effort (LPUE) as a proxy for the ...

Development of the fishery of northern anchovy (Engraulis mardax) in Baja California from 1972-1992

open access: yesCiencias Marinas, 1995
The principal changes that occurred in the northern anchovy fishery are analyzed. Data from commercial landings are examined and an explanation of the observed variations in the magnitude and composition of the catch is attempted.

Portuguese commercial fisheries of swordfish, Xiphias gladius

open access: yesFrontiers in Marine Science, 2014
Swordfish has an important role in Portuguese fisheries. Portuguese commercial swordfish landings were analyzed from 1986 to 2012. Commercial landings of five incidental catches of pelagic sharks (Alopias superciliosus, Alopias vulpinus, Isurus ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Changes in the abundance and spatial distribution of the Atlantic chub mackerel (Scomber colias) in the pelagic ecosystem and fisheries off Portugal

open access: yesScientia Marina, 2013
This study describes changes in abundance and spatial distribution of Atlantic chub mackerel in the Portuguese waters and the Spanish waters of the Gulf of Cadiz using data from acoustic surveys from 1995 to 2010 and data from the fishery since 1958. The

Beyond discards: cascading socio-economic and environmental effects of a commercial aggregate landings program in Rhode Island

open access: yesFrontiers in Marine Science, 2023
Flexible approaches to commercial fisheries harvest have been designed to meet management objectives. Rights-based management tools have been problematic for fishing businesses in certain scenarios, whereas aggregate landings approaches may offer similar

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Quantifying the economic effects of different fishery management regimes in two otherwise similar fisheries

open access: yesPLoS ONE, 2023
In the southeast U.S., two very similar fisheries are managed by very different management regimes. In the Gulf of Mexico Reef Fish fishery, all major species are managed by individual transferable quotas (ITQs). The neighboring S.

Identifying unregulated fisheries seasonality through commercial landings and local fishers’ knowledge

open access: yesFrontiers in Marine Science
Seasonality in fisheries is known when opening and closing dates are established, but it is much less defined in places lacking seasonal regulations. Highlighting fisheries seasonality is critical because, for one, it can influence seafood supply and ...
