Fish oils originate from the tissues of oily fish. Sharks, swordfish, tilefish, and albacore tuna contain high levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both forms of omega-3 fatty acids. Some individuals take fish oil supplements to help attention deficit-hyperactivity...

Sharks, like other fish, react to capture and handling stress with more exaggerated physiological responses than most other vertebrates, and the potential consequences of their capture include both sub-lethal and lethal effects. Blue sharks, Prionace glauca, are one of the most heavily exploited...

There is an increasing need to understand the interaction of marine fauna with line fishing, both recreational and commercial, particularly in regions where shark depredation has become an increasing issue. The dynamic nature of the fishing requires underwater filming techniques that can move with...

The post-release mortality (PRM) rate of sharks can be an important factor in estimating overall mortality in stock assessments. However, the accuracy of PRM rates is dependent on our ability to evaluate mortality under realistic fishing practices and conditions. In the Southeast U.S. recreational...

Incidental capture of sharks during commercial and recreational fishing is of major conservation concern because of the potential effects it can have on physiological stress responses and survival. Endocrine aspects of the stress response are, however, poorly understood in elasmobranchs because of...

This paper intends to illustrate to what extent the construction of the risk of shark attacks and its management reveal developments in surfing in la Réunion. The survey presented is based on a mixed methodology: the making of monograph from "whistleblowers" associations and analysis of their...

Wound healing is important for marine taxa such as elasmobranchs, which can incur a range of natural and anthropogenic wounds throughout their life history. There is evidence that this group shows a high capacity for external wound healing. However, anthropogenic wounds may become more frequent due ...

For centuries, the primary manner in which humans have interacted with sharks has been fishing. A combination of their slow-growing nature and high use-values have resulted in population declines for many species around the world, and to date the vast majority of fisheries-related work on sharks...

The popularity of recreational shark fishing appears to be on the rise in recent years, with current policies often failing to address the direct targeting of protected species in this sector. Examination of catch trends from the past decade revealed that more than 66 million sharks were caught by...

In the coastal waters of the southeastern United States, the blacktip shark (Carcharhinus limbatus) is targeted by recreational anglers and is currently one of the most often captured large coastal shark species. We estimated postrelease mortality (PRM) rates for blacktip sharks captured on rod and ...
