Southeast (SE) Asia is a highly biodiverse region, yet it is also estimated to cumulatively contribute a third of the total global marine plastic pollution. This threat is known to have adverse impacts on marine megafauna, however, understanding of its impacts has recently been highlighted as a priority for research in the region. To address this knowledge gap, a structured literature review was conducted for species of cartilaginous fishes, marine mammals, marine reptiles, and seabirds present in SE Asia, collating cases on a global scale to allow for comparison, coupled with a regional expert elicitation to gather additional published and …
Microdebris Abundance, Distribution, And Ingestion By Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia L. Lestrade, Frank Hernandez
Microdebris Abundance, Distribution, And Ingestion By Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia L. Lestrade, Frank Hernandez
Gulf and Caribbean Research
Holopelagic Sargassum is a critical nursery habitat for the early life stages of many marine fishes, including several federally managed species in the United States and Caribbean. Sargassum is often aggregated along surface convergence features where microdebris (synthetic, semi—synthetic, and naturally—derived particles size) have also been found in relatively high concentrations. In this study, we collected microdebris from Sargassum and adjacent open water habitats (in 2018), and juvenile fishes from Sargassum (in 2017 and 2018) in the northern Gulf of Mexico to quantify habitat—specific microdebris concentrations and the degree to which Sargassum—associated juvenile fishes ingest microdebris. Microdebris concentrations within …
The Distribution, Composition, And Management Of Drifting Fish Aggregating Devices (Dfads) In The North Atlantic Ocean, Erin E. Kimak
The Distribution, Composition, And Management Of Drifting Fish Aggregating Devices (Dfads) In The North Atlantic Ocean, Erin E. Kimak
All HCAS Student Capstones, Theses, and Dissertations
Drifting Fish Aggregating Devices (dFADs) are a gear accessory utilized on a global scale by commercial fishers to increase catch size and efficiency of target pelagic fishes such as tuna and dolphinfish. Despite their widespread use, there are few scientific estimates of the total number of abandoned or beached dFADs in the Atlantic Ocean and Caribbean Basin or the compliance of dFAD use with t-RFMO recommendations. Previous studies have utilized the modeled drift trajectories of dFADs to predict beaching probability and location, but this study is the first of its kind, analyzing true beaching events. This study identifies the beaching …
Evaluating Optimal Removal Of Derelict Blue Crab Pots In Virginia, Us, Andrew M. Scheld, Donna M. Bilkovic, Kirk J. Havens
Evaluating Optimal Removal Of Derelict Blue Crab Pots In Virginia, Us, Andrew M. Scheld, Donna M. Bilkovic, Kirk J. Havens
VIMS Articles
Derelict fishing gear is a growing concern in many fisheries and coastal communities. Pots and traps are prevalent forms of derelict fishing gear with numerous documented harmful effects. In the Chesapeake Bay, US, a large blue crab (Callinectes sapidus) pot fishery produces high levels of derelict gear. From 2008 to 2014, 34,408 derelict pots were removed from blue crab fishing areas in Virginia. This research first evaluates whether observed increases in catch rates occurring contemporaneously with the removal program were the result of derelict gear removals. An econometric production model is then used to estimate marginal removal benefits …
Caribbean Fad Tracking Project Dataset, Erin E. Kimak, David W. Kerstetter, Thomas D. Pitchford
Caribbean Fad Tracking Project Dataset, Erin E. Kimak, David W. Kerstetter, Thomas D. Pitchford
Kerstetter Fisheries and Avian Ecology Lab Datasets
This dataset encompasses crowd-sourced reports of abandoned, lost or otherwise discarded fishing gear (ALDFG), particularly drifting Fish Aggregating Devices (dFADs) from citizen scientists around the North Atlantic Ocean and greater Caribbean region. Data collection did not involve survey efforts, but rather keyword searches of affiliated terms such as "bamboo raft" and "satellite buoy", as well as collection of reports via email and Facebook. Although this dataset is incomplete and an under representation of the total number of ALDFG dFADs as a result of widespread nature of stranding locations, it provides a minimum estimate of the numbers of FADs stranding in …

Samish Indian Nation Department Of Natural Resources' Efforts To Remove Marine Debris And Creosote Using Gis In The San Juan Archipelago, Washington State, Casey Palmer-Mcgee
Salish Sea Ecosystem Conference
Samish people have been stewards of the environment in the San Juan Archipelago for hundreds of generations. As a Coast Salish Tribe, Samish culture and traditions are intimately tied to resources and places in the Salish Sea. Every beach in Samish Traditional Territory has seen footprints of the ancestors. Honoring traditional ways while preserving cultural use materials and foods for future generations is a cornerstone that guides the work of Samish DNR. In the past 4 years, Samish DNR in partnership with Washington DNR, Washington Conservation Corps, Veterans Conservation Corps, and Earthcorps, have removed over 580,000 pounds of creosote and …
Toward A Standard Trash Assessment Method, Sydney Harris
Toward A Standard Trash Assessment Method, Sydney Harris
Salish Sea Ecosystem Conference
How much trash is carried from inland areas to the ocean? Where does hazardous solid waste accumulate once it has escaped into the environment? What are the most effective upstream interventions for waste reduction and the prevention of aquatic debris? These questions cannot be answered without reliable trash metrics. ORISE Research Participant Sydney Harris has worked with a national team of EPA staff to develop a standardized trash assessment protocol built upon existing methods including California’s Urban Rapid Trash Assessment, NOAA’s Shoreline Monitoring program, and others. This new tool will, for the first time, enable trash assessment in any environment …
Testing The Effectiveness Of Escapement Mechanisms In Derelict Crab Pots, Jason Morgan, Kyle Antonelis
Testing The Effectiveness Of Escapement Mechanisms In Derelict Crab Pots, Jason Morgan, Kyle Antonelis
Salish Sea Ecosystem Conference
An estimated 12,193 pots become derelict each year in Puget Sound accounting for the annual mortality of 178,874 legal sized male Dungeness crab.1 Washington State law requires that all crab pots be equipped with biodegradable escape cord that will disintegrate over a period of time, disabling the pot by providing entrapped crab an egress route previously held closed by the escape cord. However, field observations during the Northwest Straits Foundation’s removals of over 5,000 derelict crab pots from Puget Sound have shown that disabling mechanisms for derelict crab pots do not always guarantee escapement. A 2007 study on Dungeness crab …
Barriers To The Elimination Of Plastic In Single Use Beverage Containers In Byron Bay, Nsw, Katherine Senechal
Barriers To The Elimination Of Plastic In Single Use Beverage Containers In Byron Bay, Nsw, Katherine Senechal
Independent Study Project (ISP) Collection
Plastic debris is a global threat to the natural environment. The accumulation of plastic debris has resulted in the destruction of marine habitat as well as a threat to marine wildlife. Single use plastics, including plastics associated with single use food and beverage containers are contributing to a considerable amount of debris and other litter in the world’s oceans. As awareness of this issue spreads, both large corporations and small businesses are beginning to transition to plastic alternatives for their single use beverage containers. In Byron Bay, Australia, an area of increasing environmental awareness, businesses are beginning to reduce single …

Reports
Developing standardized protocols to assess the ecological and socio-economic effects of marine debris – especially, derelict fishing gear – is critical for the protection of natural resources and for evaluating policies and programs designed to reduce and remove debris. This document outlines a Derelict Fishing Gear Assessment Framework to guide the development and implementation of derelict gear assessment, management and mitigation. The framework draws from techniques and protocols developed to assess derelict crab traps effects in the Chesapeake Bay and on past derelict gear assessments either conducted by or known to the framework authors. However, this framework is generalized and …
