Experimental Population Dynamics Of Amyloodiniumocellatum In The Spotted Seatrout, Cynoscion Nebulosus, And The Red Snapper, Lutjanus Campechanus, Ignacio Masson

Dissertations

Amyloodinium ocellatum is a parasitic dinoflagellate that infects warm water marine bony fishes and causes high mortalities in aquaculture settings. It has three life history stages: the feeding trophont, the reproductive tomont, and the infective dinospore. This dissertation describes the characteristics of A. ocellatum infections in juvenile spotted seatrout, Cynoscion nebulosus, and red snapper, Lutjanus campechanus, studies the survival and fecundities of the stages in the life cycle of the parasite and presents a population model for A. ocellatum.

At 25°C and 33 ppt, the peak of trophont detachment occurred on day 2 postinfection in spotted seatrout and day 3 …

Conservation Genetics And Systematics Of Several Turtles Species In The Southeastern United States, Joshua Robert Ennen

Dissertations

Chelonians (i.e., turtles) are an imperiled group of reptiles with about 66% of the recognized species listed as threatened by the IUCN. Most chelonian species have a unique set of life history traits (i.e., longevity, delayed sexual maturity, and low juvenile survivorship), which makes their populations exceedingly sensitive to increases in adult and juvenile moralities. With numerous anthropogenic effects (e.g., habitat alteration, exploitation, and over harvesting) negatively influencing mortality rates, chelonians have experienced global precipitous declines and extinctions.

This dissertation focuses on species within two chelonian genera, Gopherus and Graptemys. Although these two genera are vastly different ecologically, they are …

Arsenic Transport By Zebrafish Aquaglyceroporins, Mohamad Hamdi, Marco A. Sanchez, Lauren C. Beene, Qianyong Liu, Scott M. Landfear, Barry P. Rosen, Zijuan Liu

HWCOM Faculty Publications

Background

Arsenic is one of the most ubiquitous toxins and endangers the health of tens of millions of humans worldwide. It is a mainly a water-borne contaminant. Inorganic trivalent arsenic (As^III) is one of the major species that exists environmentally. The transport of As^III has been studied in microbes, plants and mammals. Members of the aquaglyceroporin family have been shown to actively conduct As^III and its organic metabolite, monomethylarsenite (MAs^III). However, the transport of As^III and MAs^III in in any fish species has not been characterized.

Results

In this study, five members …

Fisheries Research Report No.196 - Management Of Bioeroding Sponges In Wild Stocks Of Pinctada Maxima In Western Australia, Sabine Daume, Jane Fromont, Anthony M. Hart

Fisheries research reports

Final FRDC Report – Project 2005/074

The Western Australian fishery is the only remaining significant fishery for pearl oysters in the world and comprises most of the exported pearl product of Australia, currently worth around $125 million annually. The majority of pearl shells used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller ‘culture’ shell (4-5 years age class, 120mm - 160mm shell length) that are more suitable for growing pearls, leaving larger MOP oysters (6+ age class, 175mm+) on the fishing grounds.

Silver-lipped pearl oysters (Pinctada …

Fisheries Occasional Publication No. 68 - A Quota Management System For The Western Rock Lobster Fishery, Rock Lobster Industry Advisory Committee (Rliac), Department Of Fisheries, Western Australia

Fisheries occasional publications

There has been much debate over the past two decades on the most appropriate long-term management framework for Western Australia’s Western Rock Lobster Fishery. More recently a debate over whether the fishery would be best managed under a Quota Management System (QMS) or the continuation of the current Input Control Management System (ICMS) culminated in an industry vote coordinated by the Western Rock Lobster Council (WRLC) in 2006 . The outcome of this vote resulted in industry support to retain the existing management system based on input controls2 , however, shortly after the vote there was a renewed level of …

Fisheries Research Report No.157 - The Western Rock Lobster Fishery 2003/2004 And 2004/2005, Simon De Lestang, E H. Barker

Fisheries research reports

The 2003/2004 season produced the second highest catch recorded to date (13,684 tonnes), up markedly on the previous season’s catch of 11,415 t. Nominal effort in 2003/2004 (10,180,444 pot lifts) did not vary by nearly as much as did the catch, with total pot lifts declining only slightly (<1%) on the previous season. Season 2004/2005 produced a catch of 12, 236 tonnes, down on the previous season’s catch of 13,684 t. Similar to the catch, total nominal effort in 2004/2005 (9,789,671 pot lifts) also declined fairly substantially (4%) on the previous season. Recreational catches for the above two seasons were also down on their respective previous seasons by 52 and 11% each.

Puerulus settlement coast wide during 2003/2004 was below average, especially towards the southern and northern extremes of the fishery (Port Gregory and Jurien Bay south). This was also the case during the following season (2004/2005), although the poor settlement was more evenly spread across the entire fishery. Catch predictions from these …

The Effects Of Climate Variability On The Structure Of The Phytoplankton Community In Tumaco Bay, Colombia, Ingrid Garcia-Hansen Honkala

Dissertations

Spatiotemporal variability in the diatom and dinoflagellate community structure and chlorophyll a (chl a) concentrations in Tumaco Bay during the 1993-2005 period was related clearly to seasonal and interannual variability in environmental conditions due to the migration of the Inter-tropical Convergence Zone (ITZC) and the influence of El Nino Southern Oscillation (ENSO) events. A total of 134 species of diatoms that belong to 57 genera, and 78 species of dinoflagellates that belong to 25 genera were identified during the survey. The diatom community was the dominant group in the waters of the bay, being the most abundant with the greatest …

A Molecular Phylogeny Of The Remoras And Their Relatives, Kn Gray, Jan Mcdowell, Bb Collette, Je Graves

VIMS Articles

The Echeneoidea comprise three families of cosmopolitan tropical/subtropical marine fishes: the Echeneidae (remoras), Coryphaenidae (dolphin fishes), and Rachycentridae (cobia). Complete nucleotide sequences from the mitochondrial 12S rRNA, 16S rRNA, protein-coding ND2, and nuclear ITS-1 gene regions were used to reconstruct the phylogenetic history of these fishes. Parsimony, maximum likelihood, and Bayesian analyses of combined data sets resolved trees of similar topology. Congruent with evolutionary hypotheses based on larval morphology, a monophyletic Rachycentridae + Coryphaenidae was resolved with high support. Within a monophyletic Echeneidae, the subfamilies Echeneinae and Remorinae were monophyletic. In agreement with recent morphological analyses, the genus Remora was …

Fisheries Research Report No. 183 - Development Of A Long-Term Program To Monitor Coastal Communities Within The Swan Region, Lynda M. Bellchambers

Fisheries research reports

Marine benthic communities along the metropolitan coast of Western Australia are varied and unique. The southward flowing Leeuwin Current brings warm water and tropical recruits whilst the cooler counter current, the Capes Current, brings the temperate recruits. The result is a mosaic of tropical species intermingled with the dominant temperate species. These areas sustain varied fish and invertebrate communities making this coast a highly desirable location for recreational and commercial use. Management strategies are in place that attempt to maintain the sustainability of this area including various fishery restrictions and the implementation of areas zoned as sanctuary zones (no-take). However, …

An Investigation Of The Global Population Structure Of The Marlinsucker (Remora Osteochir) Inferred From Mitochondrial Control Region Dna Sequence Analysis, Gn Kurtis, Jan Mcdowell, Bb Collette, John Graves

VIMS Articles

Nucleotide sequences from the hypervariable mitochondrial control region were used to investigate phylogeographic structuring in the marlinsucker, Remora osteochir (Cuvier, 1829). Complete DNA sequences were isolated from 71 individuals collected from seven geographically distant sample locations (5 Atlantic and 2 Pacific). Analyses of molecular variance (AMOVA) and Phi st resolved significant levels of population structuring among collections from the Atlantic and Pacific oceans, whereas negligible levels of population structuring were resolved among collections from within the Atlantic or Pacific oceans. Cluster analysis of haplotypes based upon inter-haplotype divergences resolved two distinct evolutionary lineages, one composed of haplotypes that only occurred …

Ecology Of Small Neritic Fishes In The Western Gulf Of Alaska. Ii. Consumption Of Krill In Relation To Krill Standing Stock And The Physical Environment, Matthew T. Wilson, Christina M. Jump, Andre Buchheister

VIMS Articles

Krill (Euphausiacea) is a patchily distributed taxon whose availability may limit neritic fishes in temperate oceans. In the western Gulf of Alaska, krill-fish aggregations were associated with high-flow areas over the shelf. We examined fish impacts on krill standing stocks in areas of different temperature, salinity, and net current velocity. Samples were collected during September 2000, 2001, and 2003 over a 48-site grid within a known walleye pollock nursery. Krill were a dietary staple of the dominant fishes: walleye pollock Theragra chalcogramma, capelin Mallotus villosus, and eulachon Thaleichthys pacificus, but their proportion in diets varied by predator species and predator …

Patterns Of Larval Atlantic Croaker Ingress Into Chesapeake Bay, Usa, Jason J. Schaffler, Christian S. Reiss, Cynthia M. Jones

OES Faculty Publications

We compared ingress patterns of Atlantic croaker Micropogonias undulatus larvae into Chesapeake Bay, USA, with published ingress patterns through barrier island inlets, the accepted model for larval fish ingress. This model asserts that larvae ingress on night flood tides at the flooddominated side of the inlet and at all depths. At the Chesapeake Bay mouth and in the adjacent coastal waters, we compared the distribution of abundance, size, age, and growth rates of croaker prior to ingress, In contrast to the barrier island inlet model, croaker larvae were more abundant at depth than closer to the surface regardless of location. …
