When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Selectivity of gillnets in the California Pacific herring roe fishery [PDF]

open access: yes, 1977
Pacific herring, Clupea harengus, landings were sampled during the 1976 season in San Francisco, Tomales and Outer Bodega bays. Fish were sampled according to the type of gear used to catch them - - roundhaul nets (purse seines and lamparas), beach ...

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

open access: yesIntegrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Mesh Size Selectivity of Tie-Down Gillnets for the Blackfin Flounder (Glyptocephalus stelleri) in Korea

open access: yesApplied Sciences, 2021
Although gillnet fisheries are increasingly common in Korea, few studies have conducted sea trials using tie-down gillnets. Here, we analyzed the mesh size selectivity using tie-down gillnets with four different mesh sizes (84, 90, 105, and 120 mm) to ...

Comparative review of entanglement risk assessments for cetacean conservation and management

open access: yesConservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

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

open access: yesConservation 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.

Selection due to nonretention mortality in gillnet fisheries for salmon [PDF]

open access: yesEvolutionary Applications, 2010
AbstractFisheries often exert selective pressures through elevated mortality on a nonrandom component of exploited stocks. Selective removal of individuals will alter the composition of a given population, with potential consequences for its size structure, stability and evolution. Gillnets are known to harvest fish according to size.

Does nature shape risk preferences? Evidence from Chile, Norway, and Tanzania

open access: yesEconomic Inquiry, Volume 63, Issue 2, Page 568-590, April 2025.
Abstract Does exposure to a more risky environment affect risk preferences? Going beyond single‐case study evidence, we report results from five surveys conducted in three countries and link this with administrative data to study whether a link between exposure and preferences is detectable and widespread. We find no evidence for endogenous preferences
