Abstract As many tropical aquatic ecosystems worldwide, the Doce River estuary (DRE, southeastern Brazil) has increasingly faced multiple anthropogenic threats, including deforestation, mining, species introduction and water management. The 2015 collapse of the Fundão iron ore tailings dam severely changed water properties and increased heavy metal ...

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 ...

Abstract Atlantic herring Clupea harengus are total spawners that exhibit a large degree of reproductive plasticity and have substantial intra‐annual variation in their energetic condition. Recent research suggests that the species may be declining in energetic condition in the northwest Atlantic Ocean from the few historical records, but comparisons ...

Abstract Coryphaenoides Gunnerus, 1765 comprises 66 valid species of deep‐sea fishes commonly known as grenadiers, with 6 previously reported from Brazilian waters. Here, we make the first records for Coryphaenoides striaturus and Coryphaenoides subserrulatus on the Brazilian continental slope. Both species are distributed in the subtropical regions of

Abstract There is a growing body of literature that suggests riverine fish are some of the most threatened taxa on a global scale. Similarly, the literature suggests less‐altered tributaries may offer refugia for large‐river specialists. The greater Mississippi River basin, including the Missouri River system, has been subjected to anthropogenic ...

Abstract Using DNA techniques for prey identification is an emerging approach for enhancing the precision and accuracy of trophic information. We evaluated the effectiveness of DNA‐based prey identification in conjunction with visual stomach content analysis of commercially important groundfish in the nearshore Gulf of Maine, with a focus on ...

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