Using global fishery outputs from 62 countries during the period 2001–2020, this study applies threshold panel data model of Hansen (2000) to empirically explore nonlinear relations between number fishing vessels, fishers, and production, with distinct overfishing stocks (overfishing) fish caught by trawling or dredging techniques (trawling) as variables. Our findings show that levels could be ...

Blooms of alien invasive marine algae have become common, greatly altering the health and stability of nearshore marine ecosystems. Concurrently, herbivorous fishes have been severely overfished in many locations worldwide, contributing to increases in macroalgal cover. We used a multi-pronged, interdisciplinary approach to test if higher biomass of herbivorous fishes inside a no-take marine re...

The sergestid shrimp, Sergia lucens is one of the major marine resources in the waters off southwestern Taiwan. The maximum sustainable yield (MSY), total allowable catch (TAC) and fishing effort at MSY (EMSY) of the sergestid shrimp in this area were estimated to be 1008 tons, 907 tons and 11292 vessel-day, respectively by using the surplus production model with deterministic observation-error...

Several data-poor stock assessment methods have recently been proposed and applied to fisheries around the world. The Mauritanian pink spiny lobster fishery has a long history of boom bust dynamics, with large landings, collapse, years-long closures, all happening several times. In this study, we used catch, fishing efforts, length-frequency data (LFD) obtained from in its most recent period ac...

Stock assessment is necessary to understand the status of fishery stocks. However, for data-poor fishery, it very challenging assess stock status. The length-based Bayesian biomass (LBB) technique one most powerful methods fisheries resources that need simple length frequency (LF) data. Addressing present gap, this study aimed three sardines (Sardinella fimbriata, Dussumieria acuta, and D. elop...

The Northern Demersal Working Group (NDWG) prepared the assessment. The working group (Appendix 1) held three different meetings over a three month period. The meeting dates and locations are listed below. Working group participation differed by meeting. A complete summary of working group participants by meeting and day are presented in Appendix 1. SAW 53 Terms of Reference A. Gulf of Maine At...

Consumer-mediated indirect effects at the community level are difficult to demonstrate empirically. Here, we show an explicit indirect effect of overfishing on competition between sponges and reef-building corals from surveys of 69 sites across the Caribbean. Leveraging the large-scale, long-term removal of sponge predators, we selected overfished sites where intensive methods, primarily fish-t...

Abstract Small-scale fisheries play a critical role in food security and contribute to nearly half of reported global fish catches. However, the status most small-scale stocks is still poor. In data-limited situations, length-based methods have been widely applied estimate reference points understand stock status. This study three different assessment (length-based indicators—LBI, spawning pote...

Community interactions alter the management actions necessary to recover overfished species using marine reserves. For example, in communities where a larger species preys on their juveniles’ competitors, overfishing of the larger species may cause prey population expansion; subsequent increased competition for the juveniles of the overfished species may impede its recovery within reserves. We ...

In June, 1999, a portion of the Georges Bank fishing grounds (Closed Area II) that had been closed to protect depleted groundfish stocks was opened to US commercial sea scallopers to harvest sea scallop beds that had grown substantially. Vessels that participated in the exemption fishery were each allowed a maximum of three trips in Closed Area II. A trip was limited to 10,000 pounds of scallop...
