“…Intravascular gas bubbles have been found in fresh (Code 2) odontocetes that were by-caught at considerable depth (>100 m) and probably relate to nitrogen off-gassing post mortem from supersaturated tissues as the by-caught carcass returns to the surface (Moore et al 2009). Bubbles may not be seen in Code 2 carcasses which have been by-caught at shallower depths.…”

Post-mortem examination of dead and live stranded beach-cast pinnipeds and cetaceans for determination of a cause of death provides valuable information for the management, mitigation and prosecution of unintentional and sometimes malicious human impacts, such as vessel collision, fishing gear entanglement and gunshot. Delayed discovery, inaccessibility, logistics, human safety concerns, and weather make these events challenging. Over the past 3 decades, in response to public concern and federal and state or provincial regulations mandating such investigations to inform mitigation efforts, there has been an increasing effort to objectively and systematically investigate these strandings from a diagnostic and forensic perspective. This Theme Section provides basic investigative methods, and case definitions for each of the more commonly recognized case presentations of human interactions in pinnipeds and cetaceans. Wild animals are often adversely affected by factors such as parasitism, anthropogenic contaminants, biotoxins, subclinical microbial infections and competing habitat uses, such as prey depletion and elevated background and episodic noise. Understanding the potential contribution of these subclinical factors in predisposing or contributing to a particular case of trauma of human origin is hampered, especially where putrefaction is significant and resources as well as expertise are limited. These case criteria descriptions attempt to acknowledge those confounding factors to enable an appreciation of the significance of the observed human-derived trauma in that broader context where possible.

“…The impacts of debris, such as ingestion, entanglement, and habitat degradation are occurring in every ocean worldwide. Entanglement in marine debris is a major problem for marine fauna, including marine mammals, sea turtles, sea birds, fish, sharks, and crustaceans [4] [5] [6]. Marine debris, such as fishing gear, is particularly problematic for marine animals that breathe air, travel large distances and dive for food.…”

Entanglement in marine debris has become a serious matter for marine fauna, yet most data come from deceased animals. Here we studied a non-lethal entanglement event involving a female juvenile bottlenose dolphin (Tursiops aduncus), known as EDE, in Shark Bay, Western Australia who has been monitored and observed since birth as part of a long-term study. We compared her behavior before, during, and after entanglement. During entanglement, EDE markedly decreased time spent foraging, and increased time spent traveling. In contrast to before and after entanglement, EDE was mostly alone during entanglement, which may compound the negative impacts in a social species. During entanglement, erratic behaviors including leaps and fast swims were frequent. After entanglement, her activity budget and associations were similar to the period before entanglement. This study marks a rare opportunity to systematically examine the effects of entanglement on dolphin behavior and has implications for other highly social marine species.

“…The review also attributed all fishing-related gear events in a North Pacific study (Moore et al 2009) to ALDFG, despite the conclusion by the study authors that "fishing gear involved in entanglements in this study could be either active gear or discarded gear." Two North Pacific studies that focused only on entanglement injuries were also included despite the fact that no gear information was presented by the original sources (Bradford et al, 2009;Neilson et al, 2009).…”
