A Comparison Of Diets And Water Agitation Methods For Larval Culture Of The Edible Sea Urchin, Tripneustes Ventricosus (Echinodermata: Echinoidea), Ray Wolcott, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

Tripneustes ventricosus (Lamarck, 1816) has been harvested for human consumption in the Caribbean for centuries, where harvest rates occasionally exceed sustainability. Historically a backreef and grass-bed urchin, the species has recently been observed on the forereef where it appears to control macroalgal growth in the absence of Diadema antillarum (Philippi, 1845) (Woodley and Gayle, 1999). Large-scale culturing has the potential to produce T. ventricosus in sufficient numbers for remediation of degraded coral reefs, restocking of nearshore habitats, and development of an aquaculture industry for one or more Caribbean islands. We report the first successful culturing of T. ventricosus from fertilization …

Assessing The Health Of Fringing Salt Marshes Along The Fore River And Its Tributaries, Pamela A. Morgan, Lucas Curci, Cayce Dalton, Jeremy Miller

Environmental Studies Faculty Publications

Casco Bay has experienced two significant oil spills in recent history - the Tamano Tanker spill in 1972 and the Julie N spill in 1996. In addition, the Fore River and its tributaries have experienced numerous small spills over the years, including the August 2002 fuel oil spill (2,900 gallons) and the April 2003 jet fuel spill (6,000 gallons). The impacts of these spills on the fringing salt marshes that line the edges of the Fore River and its tributaries are not well understood. Are these salt marshes resilient enough to withstand these impacts and still act as healthy marshes …

The Development Of A Rigorous Sampling Methodology For A Long-Term Annual Index Of Recruitment For Finfish Species From South-Western Australia, Daniel J. Gaughan, Suzanne G. Ayvazian, G Nowara, M Craine

Fisheries Research Reports

This study has determined the optimal strategies to achieve statistically robust indices of recruitment of five key finfish species in south-western Australia. For another two species such indices could not be established. The sampling strategies developed will initially focus on the most appropriate location, month, and lunar phase, after which fine-tuning of the sampling activity will be undertaken with respect to time of day, tide height, weather conditions etc. A significant outcome from the project is that five finfish species have a sampling strategy for recruits that can be utilized as a monitoring program for the recreational and commercial fisheries …

Management Of The Proposed South Coast Trawl Fishery. A Discussion Paper., Department Of Fisheries.

Fisheries Management Papers

In late 1987, the Minister approved a development plan for the South Coast Inshore Trawl Fishery (Fisheries Management Paper No. 13) and made a number of notices regulating trawling activities in the Recherche Archipelago. Fishing Boat Licences were subsequently ‘endorsed’ by reference to those notices. The development plan was declared to be for a period ending 31 December 1989, subject to extension for a further year if necessary. Despite the considerable interest in the fishery during 1986 to 1989, fishing results demonstrated that the economic returns were marginal and a number of operators withdrew from participation in the fishery (at …

Bioluminescence Intensity Modeling And Sampling Strategy Optimization, I. Shulman, D.J. Mcgillicuddy Jr., M.A. Moline, S.H.D. Haddock, J.C. Kindle, D. Nechaev

Faculty Publications

The focus of this paper is on the development of methodology for short-term (1-3 days) oceanic bioluminescence (BL) predictions and the optimization of spatial and temporal bioluminescence sampling strategies. The approach is based on predictions of bioluminescence with an advection-diffusion-reaction (tracer) model with velocities and diffusivities from a circulation model. In previous research, it was shown that short-term changes in some of the salient features in coastal bioluminescence can be explained and predicted by using this approach. At the same time, it was demonstrated that optimization of bioluminescence sampling prior to the forecast is critical for successful short-term BL predictions …

Phytoplankton Development Within Tidal Freshwater Regions Of Two Virginia Rivers, Harold G. Marshall, Lubomira Burchardt

Virginia Journal of Science

Phytoplankton composition and the range of seasonal patterns of abundance are presented for the tidal freshwater regions in two Virginia rivers based on data accumulated monthly from 1986 through 1999. Diatoms dominated the flora during spring, summer, and fall, whereas, other taxonomic categories were more representative when the river flow rates decreased, allowing for a more stable water system and increased residency time within this tidal region during summer and early fall. This summer/fall period was associated with increased water temperatures, higher productivity rates and chlorophyll levels, increased total phytoplankton abundance and species diversity. The major components of the summer …

The Marine Fishes Of Broward County, Florida: Final Report Of 1998-2002 Survey Results, Fleur M. Ferro, Lance K. B. Jordan, Richard E. Spieler

Marine & Environmental Sciences Faculty Reports

We inventoried fishes associated with three hardbottom reef tracts that are separated by sand and run parallel to the coast in sequentially deeper water offshore Broward County, Florida. Using SCUBA and the Bohnsack-Bannerot visual point count method, we recorded fish abundance, species richness, sizes (TL), and general habitat characteristics within an imaginary 15m cylinder extending from the substrate to the surface. Sites were sampled along transects at quarter nautical mile intervals along 18 nautical miles of coastline at western and eastern edges, and crest of each of the three reef tracts.

Variation In The Fluorescence Of Green Fluorescent Protein In Various Strains Of Escherichia Coli, Paul R. Letellier Jr.

Biological Sciences Theses & Dissertations

Green fluorescent protein (GFP) was first identified in the jellyfish Aequorea victoria and generated interest due to its ability to noninvasively tag and visualize cells, cellular structures, and cellular proteins. Furthermore, the expression of green fluorescent protein in Esherichia coli cells as a tool for reporting gene expression and promotor activity has become important in the understanding of gene regulation. Expression of the gfp gene was found to vary depending on the strain of E. coli possessing the gfp gene. As a result of this fluctuation in fluorescence, gene expression and hence promotor activity may be difficult to detect or …

Promoting Voluntary Land Conservation On The Lamprey, Exeter, And Squamscott River Corridors, Brian Hart

PREP Reports & Publications

With the support of the New Hampshire Estuaries Project, the Rockingham Land Trust (RLT) researched the names and addresses of landowners along the Exeter, Squamscott, and Lamprey River corridors and within the target communities. Landowners were invited to participate in one of two free, land conservation and estate planning workshops. RLT followed up with each participant by letter and phone. The goal of the project was to secure the completion of three conservation easements from participants in the workshops. Due to low landowner participation and the significant decision involved in completing a conservation transaction, this goal was determined to be …

New Records Of Deep-Sea Cusk Eels,Dicrolene Tristis And Bassozetus Multispinis (Ophidiiformes: Ophidiidae) From Taiwan, Mao-Ying Lee, Ding-An Lee, Hong-Ming Chen

Journal of Marine Science and Technology–Taiwan

This paper reports two new record species of deep-sea cusk eels, Dicrolene tristis and Bassozetus multispinis, which were recently collected by Fishery Research Institute of Taiwan from the southern (22°01’N, 120°09’E; 22°11’N, 121°02’E) and eastern (24°16’N, 122°11’E) Taiwan waters at depths more than 1000 m. D. tristis were characterized by two median and a pair of basibranchial teeth patches; B. multispinis had one basibranchial teeth patch and short pelvic fin ray. The latter species was reported to be only distributed in the Indian ocean at the depths from 1,500-2,000 m.

Patterns Of Ocean Current Variability On The West Florida Shelf Using The Self-Organizing Map, Yonggang Liu, Robert H. Weisberg

Marine Science Faculty Publications

Patterns of ocean current variability are examined on the West Florida Shelf by a neural network analysis based on the self‐organizing map (SOM), using time series of moored velocity data that span the interval October 1998–September 2001. Three characteristic spatial patterns are extracted in a 3 × 4 SOM array: spatially coherent southeastward and northwestward flow patterns with strong currents and a transition pattern of weak currents. On the synoptic weather timescale the variations of these patterns are coherent with the local winds. On the seasonal timescale the variations of the patterns are coherent with both the local winds and …

Fisheries Occasional Publication No.21 - Allocation Of The Western Rock Lobster Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to IFAAC, the Department will outline what it believes are the most practical and cost effective ways of managing a system of allocation amongst the commercial, customary and recreational sectors. This recommendation recognises that cost efficiencies and outcomes will be greatly affected by the type of allocation model that is chosen. Consequently the Department recommends that the allocation system should be based on a single allocation to each sector that is available over the entire fishery.

The Department does not recommend having any finer scale zoning of the allocations, or the creation of exclusive recreational fishing areas. …

Recruitment In Degraded Marine Habitats: A Spatially Explicit, Individual-Based Model For Spiny Lobster, Mark J. Butler Iv, Thomas W. Dolan Iii, John H. Hunt, Kenneth A. Rose, William F. Herrnkind

Biological Sciences Faculty Publications

Coastal habitats that serve as nursery grounds for numerous marine species are badly degraded, yet the traditional means of modeling populations of exploited marine species handle spatiotemporal changes in habitat characteristics and life history dynamics poorly, if at all. To explore how nursery habitat degradation impacts recruitment of a mobile, benthic species, we developed a spatially explicit, individual-based model that describes the recruitment of Caribbean spiny lobster (Panulirus argus) in the Florida Keys, where a cascade of environmental disturbances has reconfigured nursery habitat structure. In recent years, the region has experienced a series of linked perturbations, among them, seagrass die-offs, …

Development Of An Underwater Infrared Camera To Detect Manatees, Edward O. Keith

Marine & Environmental Sciences Faculty Reports

In calendar year 2004, watercraft related mortality was the second leading cause of death of the Florida manatee (Trichechus manatus latirostris) accounting for 25% of total known manatee deaths. In an attempt to reduce this significant cause of manatee mortality, the Florida Fish and Wildlife Research Institute has instituted two rounds of Manatee Avoidance Technology grants. Herein I report the results of an evaluation of the ability of underwater infrared video cameras to detect captive manatees and other non-living targets. If such cameras could detect manatees at sufficient distances, they could be mounted in the bows of watercraft …

Interannual And Decadal Variability Of The Western Pacific Sea Surface Condition For The Years 1787-2000: Reconstruction Based On Stable Isotope Record From A Guam Coral, Ryuji Asami, Tsutomu Yamada, Yasufumi Iryu, Terrence M. Quinn, Christopher P. Meyer, Gustav Paulay

Marine Science Faculty Publications

We present a monthly resolved, 213‐year stable isotope time series from a coral from Guam (13°N, 145°E), which is located on the northern edge of the western Pacific warm pool. Oxygen isotopic composition of the coral skeleton (δ¹⁸O_coral) shows seasonal, interannual, and decadal variability, which documents significant oceanographic changes related to thermal and hydrologic variations in this region. The δ¹⁸O_coral anomaly reflects sea surface temperature (SST) anomaly and sea surface salinity (SSS) anomaly with significant r values of −0.69 and 0.49, respectively, which are strongly linked to oceanographic changes that occur during El …
