Open AccessFisheries subsidies exacerbate inequities in accessing seafood nutrients in the Indian Ocean
Harmful, capacity-enhancing subsidies distort fishing activities and lead to overfishing and perverse outcomes for food security and conservation. We investigated the provision and spatial distribution of fish...

Open AccessMonitoring marine fishes using underwater video techniques in the Mediterranean Sea
The use of underwater video techniques has expanded rapidly in ecological studies and is particularly desirable in protected areas since the method does not impact the habitat or remove fish. The Mediterranean...

Open AccessIdentifying the drivers of silky shark distribution and an evaluation of protection measures
The silky shark (Carcharhinus falciformis) has experienced a significant population decline associated with intense targeted and incidental fishing pressure. Large marine protected areas (MPAs) are increasingly a...

Estimating Pelagic Fish Biomass in a Tropical Seascape Using Echosounding and Baited Stereo-Videography
The pelagic ecosystem is the ocean’s largest by volume and of major importance for food provision and carbon cycling. The high fish species diversity common in the tropics presents a major challenge for biomas...

The Influence of Oxygen Minimum Zone and Oceanographic Parameters on the Length Distribution of Five Fish Species in the Arabian Sea
Environmental conditions strongly influence fish growth and size. Temperature, salinity and oxygen can have negative effects on growth and size when species’ tolerances are exceeded. Climate modelling predicts...

Low Oxygen Zones Predict Future Condition of Fish Under Climate Change
Oxygen concentrations are predicted to decline under climate change scenarios. To assess the possible effect of low dissolved oxygen levels on fish condition, we evaluated the condition of fish in the Northwes...

Influence of Climate-Driven Low Oxygen Zones on Fish Biodiversity: A Case Study from the Arabian Sea
Fish biodiversity is at risk globally due to the climate-driven expansion of areas of low dissolved oxygen. The Arabian Sea is one of the three regions globally with a persistent oxygen minimum zone (OMZ). The...

Wild observation of putative dynamic decapod mimicry by a cuttlefish (Sepia cf. smithi)
Stereo baited remote underwater video systems (BRUVS) are widely used to document diversity, abundance, and biomass of marine wildlife and record unusual behaviours. We observed a cuttlefish appearing to mimic...

A review of a decade of lessons from one of the world’s largest MPAs: conservation gains and key challenges
Given the recent trend towards establishing very large marine protected areas (MPAs) and the high potential of these to contribute to global conservation targets, we review outcomes of the last decade of marin...

Ecological redundancy between coral reef sharks and predatory teleosts
Reef sharks may be ecologically redundant, such that other mesopredatory fishes compensate for their functions when they decline in number, preventing trophic cascades. Oral jaw gape, hereafter referred to as ...

Open AccessFirst underwater sighting of Shepherd’s beaked whale (Tasmacetus shepherdi)
Here we describe the first underwater sighting of Shepherd’s beaked whale (Tasmacetus shepherdi). Two individuals were observed together on video footage obtained via mid-water stereo-Baited Remote Underwater Vid...

Open AccessIsolation and no-entry marine reserves mitigate anthropogenic impacts on grey reef shark behavior
Reef sharks are vulnerable predators experiencing severe population declines mainly due to overexploitation. However, beyond direct exploitation, human activities can produce indirect or sub-lethal effects suc...

Open AccessModern slavery and the race to fish
Marine fisheries are in crisis, requiring twice the fishing effort of the 1950s to catch the same quantity of fish, and with many fleets operating beyond economic or ecological sustainability. A possible conse...

The Power and the Pitfalls of Large-scale, Unreplicated Natural Experiments
Large-scale, unreplicated natural experiments (LUNEs) have a unique power to test hypotheses at ecologically realistic scales and have delivered insights of great power into cosmology, evolution and geology. Y...

Cross-continent comparisons reveal differing environmental drivers of growth of the coral reef fish, Lutjanus bohar
Biochronologies provide important insights into the growth responses of fishes to past variability in physical and biological environments and, in so doing, allow modelling of likely responses to climate chan...

To knot or not? Novel feeding behaviours in moray eels
We report observations of a novel feeding behaviour in the moray eel Gymnothorax favagineus (Bloch & Schneider, 1801) and a previously undocumented application of “knotting” behaviour in G. fimbriatus (Bennett, 1...

Indicators of fishing mortality on reef-shark populations in the world’s first shark sanctuary: the need for surveillance and enforcement
Shark sanctuaries are promoted as a management tool to achieve conservation goals following global declines of shark populations. We assessed the status of reef-shark populations and indicators of fishing pre...

From sea ice to blubber: linking whale condition to krill abundance using historical whaling records
Krill (Euphausia superba) are fundamentally important in the Southern Ocean ecosystem, forming a critical food web link between primary producers and top predators. Krill abundance fluctuates with oceanographic c...

It is not just size that matters: shark cruising speeds are species-specific
Speed of locomotion plays an important role in an animal’s biology and ecology and is of particular interest in aquatic animals. Determining cruising speeds of shark—for which such data are scarce—may help to...
