Identification Of Critical Habitats For Juvenile Dhufish (Glaucosoma Hebraicum) Nrm Project 09038 – Protecting Inshore And Demersal Finfish, Paul D. Lewis, Gabby E. Mitsopoulos, Brett W. Molony

Fisheries Research Reports

The Western Australian dhufish (Glaucosoma hebraicum) is an iconic demersal species that is endemic to the lower west and south coasts of Western Australia (WA). Information on the critical habitat and distribution of juvenile dhufish, less than two years of age and ca 150 mm total length (TL), was limited to a single study in one area where they have been previously collected. Increasing the knowledge on the habitat types occupied by juvenile dhufish, the distribution of these habitats in the West Coast Bioregion and methods to potentially monitor the annual recruitment of the species are important in their management.

Nantucket’s shellfisheries are significant both locally and nationally. Locally, commercial and recreational shellfishing are critical to the Island’s history, culture, and economy. Nationally, the Island’s largest commercial shellfishery — the Nantucket bay scallop fishery is one of the last wild-harvest bay scallop fisheries in the country, but there is growing concern over the health of the overall population and the sustainability of the fishery. Given the importance of the shellfisheries on Nantucket and the drastic decline of bay scallop populations elsewhere along the Atlantic coast, there is a compelling interest in ensuring that the Town’s shellfish are managed to sustain …

The Effect Of Medetomidine On The Burying Speed Of Corbicula Fluminea, Andrew K. Schmucker

Student Publications

A new anti-fouling drug, medetomidine, was tested to determine if it reduced the burying speed of a freshwater alien-invasive bivalve species, Corbicula fluminea. Corbicula are known to damage underwater structures and must be managed with chemical paints. The burying speeds of Corbicula were measured both before and after exposure to two different concentrations of medetomidine. The burying speed of Corbicula before exposure to a 1x10^-6 M medetomidine solution was not significantly different from the burying speed after exposure (t=.55, df=21, p=.588). The burying speed of Corbicula was significantly slower after exposure to a 1x10^-5 M medetomidine solution …

Biology Faculty Publications and Presentations

The goal of the ICEFISH 2004 cruise, which was conducted on board RVIB Nathaniel B. Palmer and traversed the transitional zones linking the South Atlantic to the Southern Ocean, was to compare the evolution, ecology, adaptational biology, community structure, and population dynamics of Antarctic notothenioid fishes relative to the cool/temperate notothenioids of the sub-Antarctic. To place this work in a comprehensive ecological context, cruise participants surveyed the benthos and geology of the biogeographic provinces and island shelves on either side of the Antarctic Polar Front (or Antarctic Convergence). Genome-enabled comparison of the responses of cold-living and temperate notothenioids to heat …

Topeka Shiner (Notropis Topeka): Species Conservation Assessment, Melissa J. Panella

Nebraska Game and Parks Commission: Publications

The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Topeka shiner (Notropis topeka) as a Tier I at-risk species of high priority for conservation. Some general management recommendations are made here regarding Topeka shiners; however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of the Topeka shiner that …

STAR Program Research Presentations

This summer I interned at the Northwest Fisheries Science Center in Seattle, WA and participated in NOAA’s Salish Sea Project. The Salish Sea Project’s goal is to identify genetically distinctive groups of species in the Salish Sea that may have unique evolutionary and/or adaptive backgrounds. These findings will allow NOAA to promote and monitor the natural production of species in the Salish Sea, to select representative populations for experimental work regarding pollution, ocean acidification and climate change, to contribute to managing the ecosystem for intra- and inter-species diversity, and to help make informed decisions about adaptive management and marine protected …

Developing Monitoring Methods For Leptasterias Spp. As Sentinel Species In Detecting Local Environmental Changes, Zachary Sturbaum, Kathryn Nuessly, Riley J. Smith, C. Sarah Cohen

STAR Program Research Presentations

Leptasterias spp., a six-rayed sea star, is found in rocky intertidal habitats ranging from Alaska to central California. Leptasterias spp. can be monitored on a broad scale throughout their range by a variety of means using timed counts and random plot censusing in order to detect both large-scale and local-level changes in the environment due to climate change, land-based human activity, or other environmental events. Leptasterias brood their young externally until the embryos grow into fully developed juveniles. These juveniles disperse by crawling away, limiting their dispersal potential. This localized dispersal provides an opportunity to use Leptasterias spp …

The Effects Of Drought On The Abundance Of The Blue Crab, Callinectes Sapidus, In The Ace Basin Nerr In South Carolina, Kirk Parmenter

All Dissertations

Blue crabs make up one of the most important commercial fisheries in the U.S. but there has been some concern over the health of blue crab populations due to large declines in landings seen in recent years. There is a significant positive correlation between river discharge and commercial landings suggesting that drought may be to blame for the recent decline in crab numbers. The work I completed for my dissertation tested multiple hypotheses examining the link between decreasing freshwater discharge, the subsequent rise in salinity, and the abundance of blue crabs in the ACE Basin National Estuarine Research Reserve.

Nutritional Content of Rhinoceros Auklet Bill Loads

Dustin E Taylor

Abstract

An adult Rhinoceros Auklet (Cerorhinca monocerata) can only catch and carry a limited amount of prey to their nestlings after a foraging trip. The auklets therefore must maximize their efficiency by bringing back the most proportionally nutritious prey items to their nestlings. The prey carried back to the nesting sites (known as a ‘bill load’) can contain whole fish, as well as parts, most commonly fish heads. This study is aimed to determine whether returning with just heads to the nestlings was proportionally more nutritious than bringing …

Effects Of Pristane On Growth Of Pink Salmon (Oncorhynchus Gorbuscha), Brielle D. Kemis, Bonita Nelson

STAR Program Research Presentations

Pristane is a naturally occurring hydrocarbon that is generated by copepods in marine ecosystems. Organisms that eat copepods do not readily metabolize pristane, which causes it to accumulate throughout the marine food web. Understanding how pristane affects marine fish is essential because pristane is often used as a bioindicator in lab studies and may be influencing results in those studies. Also, this hydrocarbon may significantly reduce growth of marine fish in the wild. A previous study indicated that pristane is an appetite suppressant and growth retardant in fish. However, the study implemented a feeding regime with unnaturally high levels of …

Bait Effects In Sampling Coral Reef Fish Assemblages With Stereo-Bruvs, Stacey R. Dorman, Euan S. Harvey, Stephen J. Newman

Fisheries Research Articles

Baited underwater video techniques are increasingly being utilised for assessing and monitoring demersal fishes because they are: 1) non extractive, 2) can be used to sample across multiple habitats and depths, 3) are cost effective, 4) sample a broader range of species than many other techniques, 5) and with greater statistical power. However, an examination of the literature demonstrates that a range of different bait types are being used. The use of different types of bait can create an additional source of variability in sampling programs. Coral reef fish assemblages at the Houtman Abrolhos Islands, Western Australia, were sampled using …

Estimating The Potential Impacts Of Large Mesopredators On Benthic Resources: Integrative Assessment Of Spotted Eagle Ray Foraging Ecology In Bermuda, Matthew J. Ajemian, Sean P. Powers, Thaddeus J. T. Murdoch

University Faculty and Staff Publications

Declines of large sharks and subsequent release of elasmobranch mesopredators (smaller sharks and rays) may pose problems for marine fisheries management as some mesopredators consume exploitable shellfish species. The spotted eagle ray (Aetobatus narinari) is the most abundant inshore elasmobranch in subtropical Bermuda, but its predatory role remains unexamined despite suspected abundance increases and its hypothesized specialization for mollusks. We utilized a combination of acoustic telemetry, benthic invertebrate sampling, gut content analysis and manipulative experiments to assess the impact of spotted eagle rays on Bermudian shellfish resources. Residency and distribution of adult spotted eagle rays was monitored over …

Response Of Sunshine Bass (Morone Chrysops X M. Saxatilis) To Digestible Protein/ Dietary Lipid Density And Ration Size At Summer Culture Temperatures In The Southern United States, Steven D. Rawles, Bartholomew W. Green, T. Gibson Gaylord, Frederic T. Barrows, Matthew Mcentire, Donald W. Freeman

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Temperature and ammonia levels often increase dramatically in ponds during summer production of sunshine bass and summer temperatures are projected to increase in the Southern United States. Extended periods of high ammonia result in fish stress, disease, mortality and significant loss of feeding days as producers attempt to reduce ammonia to manageable levels through reduced feeding or lower protein diets. A factorial feeding trial was conducted in temperature controlled tanks to investigate main and interactive effects of three digestible protein (DP) levels (33, 40, 47%), two lipid levels (10, 18%) and two ration levels (full fed: satiation, restricted: 80% of …

Fish Assemblage Dynamics And Red Drum Habitat Selection In Bayou St. John And Associated Urban Waterways Located Within The City Of New Orleans, Louisiana, Patrick W. Smith Mr.

LSU New Orleans Theses and Dissertations

Bayou St. John (BSJ) and City Park Lakes and Lagoons (CPLL) are urban waterways in New Orleans, Louisiana. I studied habitat selection of red drum in BSJ, and fish assemblage change in BSJ and CPLL over 40 years. Temperature was found to be the best predictor of red drum habitat selection in Bayou St. John, while salinity and change in depth also were found to be good predictors for certain sites. Potential prey item abundance did not appear to influence habitat selection. Using data from 1971 – 2010, nearshore habitats in CPLL were affected by Hurricane Katrina, but have sense …
