Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, Elizabeth Saraf
Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, Elizabeth Saraf
Senior Honors Projects
Since their first recorded occurrence in 1859, Pelagic Red Crabs (PRC; Pleuroncodes planipes) have experienced increased frequency of episodic mass stranding events in the Eastern Pacific Ocean. PRC’s are transported over 1,000 km northward of their central domain from the coast of central Baja California, Mexico. They have been reported by the thousands on the beaches of central and southern California. Their presence influences the surrounding ecosystem and commercial fisheries because they are nutritional prey items and large predators change their diet to incorporate PRC’s when they are available. Seasonal coastal currents and the California Undercurrent transport warmer waters …

Examination Of Polymorphism In The Serine Proteinase Inhibitor Gene In The Eastern Oyster, Crassostrea Virginica., Aine Lehane
Examination Of Polymorphism In The Serine Proteinase Inhibitor Gene In The Eastern Oyster, Crassostrea Virginica., Aine Lehane
Senior Honors Projects
Oysters are a keystone species; they are filter-feeders and reef-builders. Additionally, oysters are extremely important within the shellfish aquaculture industry; they are the second most widely produced species in world aquaculture production. Eastern oysters, Crassostrea virginica, are produced in aquaculture and are unfortunately susceptible to Dermo disease. Dermo is caused by a protozoan parasite, Perkinsus marinus, and infection is often fatal in oysters due to widespread tissue damage and blockage of blood vessels. Research in oyster disease is particularly needed because disease is one of the largest impediments faced by the aquaculture industry as entire oyster populations can …

Combating Infectious Diseases In Aquaculture With An Original Probiotic Product, Meagan Hamblin, Saebom Sohn, Christine Ahn Dao, Marta Gomez-Chiarri, David R. Nelson, David Worthen, David Rowley
Senior Honors Projects
Oyster production in Rhode Island accounts for over $2.5 million in annual revenue, making it the top aquaculture product in the state. However, larval tank infections significantly constrain production and create substantial economic losses for commercial hatcheries. In most cases antibiotics may not be used to prevent or treat larval tank infections. A probiotic, or beneficial microbe which competes with pathogens, is a safer and “green” approach to preventing infections. Vibriosis, a common cause of oyster larval mortality, is the result of Vibrio species infections. Previous studies have shown that a native Rhode Island microbe, Bacillus pumilus RI06-95, protects oyster …

Fisheries, Animal and Veterinary Sciences Faculty Publications
The elemental composition of otoliths may provide valuable information for establishing connectivity between fish nursery grounds and adult fish populations. Concentrations of Rb, Mg, Ca, Mn, Sr, Na, K, Sr, Pb, and Ba were determined by using solution-based inductively coupled plasma mass spectrometry in otoliths of young-of-the year tautog (Tautoga onitis) captured in nursery areas along the Rhode Island coast during two consecutive years. Stable oxygen (δ18O) and carbon (δ13C) isotopic ratios in young-of-the year otoliths were also analyzed with isotope ratio mass spectrometry. Chemical signatures differed significantly among the distinct nurseries within Narragansett …

Time Post-Hatch Caloric Value Of Artemia Salina, Jessie M. Sanders
Senior Honors Projects
In aquatic animal collections, such as those in the collection of Mystic Aquarium & Institute for Exploration’s Fish & Invertebrate department, live food is an essential part of the diet of animals that are on display, used in education, and kept in reserve for exhibits. For Mystic Aquarium’s Fish & Invertebrate department, newly hatched Artemia salina, or brine shrimp, are fed to an assortment of fishes and invertebrates, including soft corals and jellyfish. Hatch brine is an important source of fatty acids, which are essential for proper growth and development. Hatch brine starts encapsulated in a cyst form and are …
Mechanics Of Suction Generation During Feeding In Little Skates, Danielle Duquette
Mechanics Of Suction Generation During Feeding In Little Skates, Danielle Duquette
Senior Honors Projects
Feeding mechanisms of aquatic vertebrates has been extensively studied in the past, while that of elasmobranchs remains limited. Skates and rays are believed to have evolved from a shark ancestor, thus they represent the most derived group. All skates are dorsoventrally compressed, have a unique jaw suspension type and head skeleton and live in benthic environments. It is unknown whether these derived features of skates have altered the ancestral shark feeding mechanism. Comparing feeding mechanisms in skates and sharks may shed light on morphological transformations that have arisen after the evolutionary split of these two groups. In this study prey …

Infectious Necrotizing Enteritis And Mortality Caused By Vibrio Carachariae In Summer Flounder Paralichthys Dentatus During Intensive Culture, Bruno Soffientino, Todd Gwaltney, David R. Nelson, Jennifer L. Specker, Michael Mauel, Marta Gomez-Chiarri
Fisheries, Animal and Veterinary Sciences Faculty Publications
An epizootic causing mortality among cultured summer flounder Paralichthys dentatus occurred in summer of 1998 at a land-based facility on Narragansett Bay, Rhode Island, USA. The disease, flounder infectious necrotizing enteritis (FINE), was characterized by reddening around the anal area, distended abdomens filled with opaque serosanguineous fluid, enteritis and necrosis of the posterior intestine. In extreme cases of the disease, the posterior intestine was detached from the anus and was observed coming out the vent. The intestine of individuals that recovered from the dsease ended in a blind-sac; the abdomens of these fish were distended, due to food and water …
The Evolution Of International Fisheries Management In The North Pacific Ocean And Prospects For The Future, Paul Augustus Flynn
The Evolution Of International Fisheries Management In The North Pacific Ocean And Prospects For The Future, Paul Augustus Flynn
Theses and Major Papers
The abundant resources of the North Pacific Ocean have been the subject of international disputes and negotiations through the 20th century. The management of species which range throughout this vast area, are not under the jurisdiction of a single state. That fact has required the establishment of a framework in which allocation and conservation measures can be researched and agreed upon. This has been accomplished through various multilateral and bilateral agreements. From the voluntary Japanese suspension of a directed salmon fishery off the coast of Alaska in 1938 to recently completed multilateral treaties, significant advances have been made in Pacific …
International Organizations And Tuna Management; Problems And Future Prospects, Yuh-Chen Chern
International Organizations And Tuna Management; Problems And Future Prospects, Yuh-Chen Chern
Theses and Major Papers
A large number of marine species migrate within and without national jurisdictions and a small number occur entirely outside any national jurisdiction. Thus, the species migrating through waters under the jurisdiction of coastal states to high seas beyond the jurisdiction of any single state are defined as highly migratory species (HMS). International organizations play a key role in the management of highly migratory species. Most of the international organizations concerned with HMS focus on tuna management.
Sacrificing Conservation For Pesos: An Analysis Of Select Marine Fisheries In The Political Environment Of Mexico, Sephen W. Bourgeois Jr.
Sacrificing Conservation For Pesos: An Analysis Of Select Marine Fisheries In The Political Environment Of Mexico, Sephen W. Bourgeois Jr.
Theses and Major Papers
The decline of most Mexican fisheries has occurred so rapidly that few Mexicans and Americans alike fully appreciate the loss. The major focus of this paper will examine the false impression that Mexico is engaging in marine conservation; in reality, its conservation efforts are responses to after-the-fact actions brought on by world critics and as a vehicle to pacify conservationists. The Mexican government can pass a law but lacks the resources to administer and enforce the law and subsequently manage its fisheries in an effective manner. Rather than survey the state of every fishery found in Mexican waters, this paper …
Trends In Abundance Of The Gulf Of Maine Population Of Harbor Porpoise, Paula Ann Olson
Trends In Abundance Of The Gulf Of Maine Population Of Harbor Porpoise, Paula Ann Olson
Theses and Major Papers
Hundreds of harbor porpoise die each year as bycatch in the Gulf of Maine's sink gillnet fishery. In recent years, concern has arisen whether the Gulf of Maine population of harbor porpoise can sustain this level of bycatch. It is believed that the population may have declined, or is declining as a result of the incidental moralities. This paper reviews what is known about Gulf of Maine harbor porpoise demographics and how that information is incorporated into the management of the porpoise/fishery interaction. Included in this paper is a new study on the trend of relative abundance of harbor porpoise …

The concepts of coordinated and integrated approaches to management are discussed in the context of the present management regimes. Given the fragmented authority over the policy …
Limits To Private Aquaculture On Cape Cod, Kevin Robert Cute
Limits To Private Aquaculture On Cape Cod, Kevin Robert Cute
Theses and Major Papers
This study examined the potential of social conflict related to private and public rights, to constrain aquaculture on Cape Cod. While the ability of social conflict to constrain aquaculture has been demonstrated in a few cases, its current potential to constrain aquaculture on Cape Cod had not been established prior to this study. This study was based on information gathered from town records and public hearings related to proposed aquaculture ventures. In addition, town officials were interviewed to obtain additional information related to cases. The finding of this study is that private riparian proprietors, and interests in shell-fishing tend to …
The Role Of The Federal Aid In Sportfish Restoration Program In Promoting State Marine Artificial Reef Development Activities, Loren Clark Evans
The Role Of The Federal Aid In Sportfish Restoration Program In Promoting State Marine Artificial Reef Development Activities, Loren Clark Evans
Theses and Major Papers
The passage of the Wallop-Breaux Amendments to the Federal Aid in Sportfish Restoration Program (FASRP), in 1984, significantly increased the funding available to states participating in the Program. Subsequently, the FASRP became the largest single source of funding for state marine artificial reef development activities. In recent years, there has been concern among program constituents that FASRP funds are not being utilized as intended. The principle question of the current research focused on how effective FASRP subsidies have been in providing meaningful benefits to state fisheries management programs. Specifically, the research focused on the application of FASRP monies in promoting …

The Sultanate of Oman is a small coastal nation with a maritime history, regional trade and fisheries exploitation. Among those fishery industries is Oman's coastal abalone fishery, which command the highest prices per unit of weight among the other marine living resources. This study analyzes the fishery's biological aspects, structure, socioeconomic, policies, and management practices in an attempt to provide an understanding of the prime parameters, that in turn could be utilized for sound management purposes. it also provides a description of an integrated development and management policy for the abalone fishery. Finally, it is hoped that this research will …
The National Marine Sanctuary Designation Process And Its Impact On Naval Operations, Gregory E. Bolan
The National Marine Sanctuary Designation Process And Its Impact On Naval Operations, Gregory E. Bolan
Theses and Major Papers
This paper addresses the basis of potential and real conflicts derived by the National Environmental Protection Act (NEPA) process, as identified within and between NOAA and the United States Navy. This conflict is often exacerbated due to either a lack of communication, coordination, or both. A recent proliferation of proposed and designated marine sanctuaries in traditional Naval operating areas has complicated or hindered Naval operations (or will) to a degree where EIS derived restrictions negatively impact the Naval operations, based on (1) response readiness, and (2) increased cost of operations. Two specific conflicts are examined in a case study approach …
Atlantic Bluefin Tuna Management, Jeffrey C. Fisher
Atlantic Bluefin Tuna Management, Jeffrey C. Fisher
Theses and Major Papers
The International Commission for the Conservation of Atlantic Tunas (ICCAT) and federal management under the U.S. National marine Fisheries Service (NMFS) has certainly been contentious. Atlantic bluefin tuna have been managed at the international level by ICCAT for the past 25 years. NMFS is the organization responsible for implementing ICCAT recommended conservation and management measures in the United States. In an attempt to halt an apparent decline in the abundance of bluefin tuna in the western Atlantic, ICCAT has recommended strict management measures including catch quotas, minimum sizes, "no-sale" provisions, and spawning area protection since 1981. ICCAT had recommended in …
The Rhode Island Marine Fisheries Council: Stewardship In Need Of Goals And Objectives, Robert Censabella
The Rhode Island Marine Fisheries Council: Stewardship In Need Of Goals And Objectives, Robert Censabella
Theses and Major Papers
In the State of Rhode Island, marine fisheries are managed through the Marine Fisheries Council, a citizen-based regulatory body of nine members from either the commercial or recreational fishing industries or experienced with the conservation and management of fisheries resources. To ostensibly help this group make informed decisions, biological data and scientific advice are provided by the State Division of Fish and Wildlife. This thesis examines the decision-making process of this Council. More specifically, it provides a case study of how this body has attempted to manage the State's winter flounder stocks-an economically-valuable species which confines its life cycle mostly …
International Management Of The Western Atlantic Bluefin Tuna Fishery: Is There A Need For A Cites Listing?, Jennifer Elling-Dodge
International Management Of The Western Atlantic Bluefin Tuna Fishery: Is There A Need For A Cites Listing?, Jennifer Elling-Dodge
Theses and Major Papers
In the last two decades, the Atlantic bluefin tuna has been increasingly targeted by fishermen throughout the world, primarily for sale in Japan. Commercial fishermen, attempting to survive in a world of declining commercial catches, increased controls on fishing effort, and increasing competition, view the U.S. $50.00 or more per kilogram that might be obtained from bluefin as a financial bonanza. yet, the population of breeding adult bluefin in the western Atlantic (the focus of bluefin fishing, since the largest bluefin consistently occur there) has declined by an estimated 77% to 90% since the 1970's. In addition, the eastern Atlantic …
Assessing The Impact Of Amendment 2 To The Summer Flounder Fishery Management Plan: Implications Of State-By-State Quotas For Vessel Operators, Karen Ellis Greene
Assessing The Impact Of Amendment 2 To The Summer Flounder Fishery Management Plan: Implications Of State-By-State Quotas For Vessel Operators, Karen Ellis Greene
Theses and Major Papers
The state-by-state quota regulation contained in Amendment 2 to the Summer Flounder Fishery Management Plan became effective on January 1, 1993. The research sought to determine the implications that the state-by-state quotas have imposed on federal summer flounder permit holders. commercial fishermen were believed to have landed their summer flounder out-of-state to take advantage of more favorable possession limits in other states, and to have accrued higher costs as a result of their decisions to land out-of-state. A survey was administered to commercial fishermen in Massachusetts, Rhode Island, and North Carolina, to ascertain behavioral changes, as a result of state-by-state …
North American Sea Urchin Fishery Management Strategies: Their Applicability To The Maine Green Sea Urchin Fishery, Kate Sullivan
North American Sea Urchin Fishery Management Strategies: Their Applicability To The Maine Green Sea Urchin Fishery, Kate Sullivan
Theses and Major Papers
The Maine green sea urchin fishery has experienced dramatic growth since its inception in 1987. Landings have increased from 1.4 million pounds in 1987 to 41.6 million pounds in 1993 (NMFS, Fisheries Statistics). The reproductive gonads, referred to as roe or 'uni' are shipped fresh from Maine to japan, where the uni is a delicacy item fetching high unit prices on the Japanese fish market. The green sea urchin from Maine, Strongylocentrotus droebachiensis, is the third highest priced sea urchin product imported in Japan (Anon., 1989). Country-wide, sea urchin fisheries are one of the fastest growing fishing industries (Phu, …

The Role Played By Semisubmersible Exploratory Drilling Platforms As A Vector In Marine Biological Introductions, Sean S. Bercaw
Theses and Major Papers
Through discussion of Semisubmersible Exploratory Drilling Platforms and their role as vectors in marine biological introductions, this paper establishes a base of knowledge for future referral. Included in this project are details of semisubmersibles, their unique characteristics and operations, historical movements, past introductions, future operations, and continuing potential for invasions. The significance of semisubmersibles as biological vectors is further addressed. Three criteria will be used to assess the significance of the role of semisubmersibles in the introduction of alien species: first, what is the rate of SEDP movements over time; second, how are SEDP movements unique, and what role does …
Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche
Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche
Theses and Major Papers
The interaction of the herring (Clupea harengus) with the oil and gas industry in the North Sea is reviewed. The population crash of the herring in the early 1970's and the subsequent closing of that important fishery between 1977 and 1983 has drawn considerable attention to the influences, both biotic and abiotic, affecting the recruitment to the North Sea stock. Current accepted theory points to a change in oceanic current and the subsequent decrease in salinity in the North Sea region, resulting in a change in plankton availability for larval herring as the cause of the recruitment failure during the …
