The Talion law “tooth for a tooth”: self-defense as a motivation for shark bites on human aggressors

Frontiers in Conservation Science
The concept of “self-defense,” based on aggression by one individual responding to an initial aggression by another, has been observed in several animal taxa such as birds and terrestrial mammals but never documented in detail in sharks. Based on a multi-

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

Journal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Optimizing Water Flow With Cavitation on the NACA 0009 Hydrofoil Inspired by the Mako Shark Bumps

International Journal of Aerospace Engineering
The numerical investigation of the water flow with partial cavitation around the NACA 0009 hydrofoil with bumps inspired by the mako shark (biomimicry) was performed. The simulation was done by ANSYS Fluent software for cavitation numbers of 1 and 1.5 at

Subtropical marine reserve as key habitats for the critically endangered sand tiger shark (Carcharias taurus) in the Southwestern Atlantic

Journal of Fish Biology, EarlyView.
Abstract This study documents the occurrence, seasonal patterns and reproductive activity of the sand tiger shark (Carcharias taurus) within a no‐take marine protected area in southeastern Brazil, using Baited Remote Underwater Video (BRUV) and diving records.

Enrichment‐Based Duplex PCR for Early Detection of Potentially Virulent Vibrio harveyi in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Vibrio harveyi is an important bacterial pathogen in marine aquaculture, responsible for outbreaks affecting a wide range of fish species. Early detection of potentially virulent isolates in fish and environmental samples is essential for effective disease prevention and management, particularly under field conditions where the pathogen may be

Breakthrough Innovation Under Fire: Hedge Fund Activism and Firms' Mitigation Strategies

Journal of Product Innovation Management, EarlyView.
ABSTRACT Literature suggests that hedge fund activism is the most potent form of shareholder activism, often pressuring firms to prioritize shareholder value at the expense of innovation. Using a panel dataset of 302 listed U.S. firms with 2007 firm‐year observations from 2008 to 2020, we explore this dynamic in the context of technology‐ and market ...
