Trawling For Clues: Examining Nefmc Herring Amendment 8, Christopher Santoro
Trawling For Clues: Examining Nefmc Herring Amendment 8, Christopher Santoro
Honors Scholar Theses
In 2007, almost twenty years ago, the Magnuson-Stevens Act changed the landscape of fisheries management in the US. Through the establishment of Fisheries Management Councils (FMCs), it paved the way for top-down management approaches that helped the government combat nationwide declines or collapses in fish stocks. Among the myriad responsibilities of the FMCs was the expectation that amendments to existing fisheries management plans would be a necessity to adapt to modern circumstances. This thesis focuses on New England Fisheries Management Council's (NEFMC's) Herring Amendment 8 (A8). This amendment, passed in 2021, attempts to lay the groundwork for sustainable management of …

Using Bivalves As An Indicator For Fecal Bacteria, Kamala Chuss
Honors Scholar Theses
This project focuses on the integration of fecal bacteria from warm-blooded animals into bivalve tissue, and the utilization of bivalves as an indicator for fecal bacteria in waterways. Bivalves may give a more representative long-term average of fecal bacteria in water as compared to direct water testing. The primary objective is to create a standard operating procedure to use bacterial testing of bivalves as a proxy for bacteria concentration in the water. This method can be used in places where bivalves do not already exist by adding them to a body of water, or by collecting bivalves that already exist …

Using Single Cell Genomics To Explore The Impact Of Marine Viruses On Microbial Respiration., Paxton Tomko
MCB Articles
Viral metabolic reprograming of marine prokaryotes, through the use of virally encoded auxiliary metabolic genes (AMGs), plays a critical role in marine ecosystem function by influencing biochemical cycles and genetic diversity in these environments. Despite the fundamental role viruses play in global environmental ecosystems, they remain an understudied aspect of microbial ecology and evolution, in part due to the methods available for studying virus host interactions in natural systems. Thus far, metagenomic analyses have been used to study the interactions of virus host pairs, but these types of analyses have their limitations in accurately linking viruses to hosts, or culture-based …

Recruitment Patterns Of The Fouling Community On Eelgrass In Long Island Sound, Diana Lancaster
Recruitment Patterns Of The Fouling Community On Eelgrass In Long Island Sound, Diana Lancaster
Department of Marine Sciences
Abstract The seagrass Zostera marina (eelgrass) is typically found in shallow protected areas of portions of eastern Long Island Sound (LIS). Although the species and its associated ecosystem have been well studied in many places, work in LIS has been limited. A field study was conducted to assess the fouling communities associated with eelgrass beds around Pine Island, in eastern LIS. Samples were collected from four sites between July and October, 2011. A total of 15 species of fouling organisms were found on eelgrass leaves throughout the study period. Recruitment patterns varied spatially and temporally. Differences in the composition of …

Fish populations with broad age distributions are expected to have higher reproductive capacity than age-truncated populations because of the disproportionate contributions of older fish. Harvest slot limits, an expected means of ameliorating age truncation, are modeled for Tautog Tautoga onitis in an overfished population subunit that is experiencing overfishing. Tautog, currently managed by a 40 cm minimum size limit (MSL), is a candidate species for slots because it is relatively long-lived, slow-growing, with low discard mortality. We evaluated changes in biomass and abundance-at-age relative to management with the current MSL regulations using a forward population simulation model for four slots: …

Striped Bass Consumption Of Blueback Herring During Vernal Riverine Migrations: Does Relaxing Harvest Restrictions On A Predator Help Conserve A Prey Species Of Concern?, Justin P. Davis, Eric T. Schultz, Jason C. Vokoun
Open Access Author Fund Awardees' Articles
Anadromous blueback herring Alosa aestivalis are declining throughout much of their range, and fishery closures in some systems have failed to produce population recovery. A potential contributing factor is increased predation pressure from sympatric striped bass Morone saxatilis. We integrated data on the predator–prey interaction between striped bass and blueback herring during vernal migrations into the Connecticut River with data on the in-river striped bass fishery to assess the potential for mitigation of blueback herring mortality via increased striped bass harvest. Striped bass abundance, size structure, diets, and angler catches were assessed within a river segment during spring 2005–2008. …

Salinity Preference Of Alaskan Threespine Stickleback: Test For Divergence In Halotaxis Between Ancestral And Landlocked Populations, David C. Fryxell
Honors Scholar Theses
Glacial retreat during the Pleistocene caused landlocking of anadromous Alaskan threespine stickleback, Gasterosteus aculeatus, furnishing a natural 'experiment' in osmoregulatory divergence. The objective of this study was to assess the effects of individual acclimation and population divergence on salinity preference. Full-sibling families of marine, anadromous, and freshwater-landlocked populations of stickleback were reared in common environments until 3 weeks post-hatch, then were split and acclimated to low or high salinity. At 6 to 8 weeks of age the six experimental groups were tested for salinity preference in a tank that offers fish a choice of compartments with different salinities arranged in …

Effectiveness Of Marine Protected Areas Across A Latitudinal Gradient, Chelsea Roy
Honors Scholar Theses
Use of marine protected areas (MPA) as a tool for conservation and sustainable use of marine biological diversity is increasing worldwide. However, the geographic extent of MPA designation varies, as does a full understanding of the ecological utility of such designations. Progress towards marine conservation goals needs to be evaluated in order to determine areas lacking effective MPA designation. The goal of this study is to evaluate the representation (in terms of communities and habitats) and performance of marine protected areas in the Northwestern Atlantic and Northeastern Pacific across a latitudinal gradient. Presence or absence of MPAs in specific ecological …
An Approach For Use Of Dual Frequency Identification Sonar (Didson) To Quantify Behavioral Aspects Of Piscivory At Ecologically Relevant Time And Space Scales, Victoria E. Price
An Approach For Use Of Dual Frequency Identification Sonar (Didson) To Quantify Behavioral Aspects Of Piscivory At Ecologically Relevant Time And Space Scales, Victoria E. Price
Master's Theses
Predator-prey interactions of large vagile fishes are difficult to study in the ocean due to limitations in the space and time requirements for observations. Small-scale direct underwater observations by divers (<10m >radius) and large-scale hydroacoustic surveys (10s - 100s km2) are traditional approaches. However, large piscivorous predators identify and attack prey at the scale of meters to tens of meters. Dual- Frequency Identification Sonar, or DIDSON, is a high-resolution acoustic camera operating in the MHz range that provides detailed continuous video-like imaging of objects out to 30 m range. This technology can be used to observe predator-prey interactions at ecologically …
