Integrating migratory connectivity data into the conservation of Australian sharks and rays

Conservation Biology, EarlyView.
Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.

To release or not to release? Understanding sawfish release behavior in a global south complex fishery

Conservation Science and Practice, EarlyView.
This demonstrates the gap between existing top‐down laws and strategies (Current Approach) and the barriers fishers face while proposing an alternative pathway (Proposed Approach) based on collaboration, capacity building, and addressing socio‐economic factors.

Spatial and temporal variations in seabird bycatch: Incidental bycatch in the Norwegian coastal gillnet-fishery.

PLoS ONE, 2019
The general decline of seabird populations worldwide raises large concerns. Although multiple factors are interacting to cause the observed trends, increased mortality from incidental bycatch in fisheries has proven to be important for many species ...

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 ...

Can biodegradable materials reduce plastic pollution without decreasing catch efficiency in longline fishery? [PDF]

, 2022
Longlining is a widely used fishing method. During longline fishing, some of the snoods connecting the hooks to the mainline are often lost at sea. Since snoods are made of nylon or polyester, lost snoods contribute to marine plastic pollution. Replacing

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.
