The value of conditional prediction: Can retained species help predict unknown discards in commercial fisheries?

open access: yesJournal of Applied Ecology, Volume 62, Issue 6, Page 1392-1405, June 2025.
Due to their higher performance and reliability, we consider SSDMs valuable for modelling unobserved discards and advise caution when using conditional joint prediction for continuous response variables such as biomass, especially when overdispersion is likely.

Retention Bans Are Beneficial but Insufficient to Stop Shark Overfishing

open access: yesFish and Fisheries, Volume 26, Issue 3, Page 473-487, May 2025.
ABSTRACT Sharks are among the most threatened groups of exploited fishes, comprising common bycatch across many fisheries. Management efforts intended to safeguard threatened species have increasingly focused on retention bans to reduce bycatch mortality. However, the population effects of such measures remain unevaluated across species.

A Review of the Status of Sharks, Rays and Chimaeras of Panama to Guide Research and Conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT Chondrichthyan fishes (sharks, rays and chimaeras) are a group of high conservation concern globally. Species are impacted by varying threats, although fishing pressure is the primary stressor causing population declines. Panama comprises both Pacific and Caribbean coastlines with a diversity of estuarine and marine habitats supporting small ...

The complete mitochondrial genome of the leopard shark Triakis semifasciata (Triakidae)

open access: yesJournal of Natural History
The leopard shark Triakis semifasciata (family Triakidae) is threatened by habitat loss and targeted by recreational and commercial fishermen in the Eastern Pacific Ocean, from Oregon, USA, to the Gulf of California, Mexico. Despite environmental issues, there are few genetic and genomic resources available for this species.

Mitigating the effect of by‐catch on endangered marine life

open access: yesAnimal Conservation, Volume 28, Issue 2, Page 172-184, April 2025.
Fishing gears cause substantial impacts on the oceans and their ecosystems, and many marine animals, such as sea turtles, marine mammals, seabirds and elasmobranchs, end up as by ‐catch. In this paper, the most effective mitigation measures were investigated for each group, taking into account the fishing gear with which they interact most.
