Residency and Space Use of Endangered Smoothhound Sharks (Mustelus mustelus) in Relation to Marine Protection and Demersal Longline Fishing Along South Africa's South Coast

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shark populations are declining globally and the effectiveness of marine protected areas (MPAs) as a conservation tool may vary by species and environmental context. This study assessed space use and residency of smoothhound sharks (Mustelus mustelus)—an endangered, yet highly exploited shark—in relation to spatial protection and fishing risk ...

Global seabird bycatch in longline fisheries [PDF]

Endangered Species Research, 2011
Bycatch in longline fisheries is believed to govern the adverse conservation status of many seabird species, but no comprehensive global assessment has been undertaken. We reviewed the extent of seabird bycatch in all longline fisheries for which data are available.

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.

Selection And Mortality In Pelagic Longline Fisheries For Haddock

, 1997
No abstracts are to be cited without prior reference to the author.The bycatch of haddock (Melanogrammus aeglefinus) below legal size in the pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, is often high. This project was aimed at reducing the bycatch of undersized haddock through alterations in gear technology and ...

Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

Fisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Weathering the Storm: Effects of a Hurricane‐Induced Thermal Disturbance on a Juvenile Atlantic Halibut (Hippoglossus hippoglossus) Hotspot in Nova Scotia, Canada

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic Halibut has recently become the most valuable groundfish in Atlantic Canada following population recovery, and the benthic habitat characteristics of their aggregation areas have been identified as a key outstanding ecological knowledge gap for the species. In 2022, during a multi‐year acoustic tracking study in a key juvenile hotspot

Status of off-bottom mariculture in wave-exposed environments. Part 2. Comparative loading and motion of longline designs currently used in exposed commercial farms

Frontiers in Aquaculture
A global inventory of extractive species mariculture in wave-exposed temperate waters shows that the longline is the technology used in more than 99% of the sites (Part 1 of this review).

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...
