Interactive Effects Of Flow Regime, Climate Change, And Angler Harvest On Smallmouth Bass At The Southern Range Extent, Christopher Middaugh

Graduate Theses and Dissertations

The Ozark-Ouachita Interior Highlands of Arkansas, Oklahoma, and Missouri are the southern extent of native Smallmouth Bass Micropterus dolomieu range. Smallmouth Bass are an important species economically and ecologically, but it is unknown how climate change may affect them in this region and in particular how Smallmouth Bass may be affected differently across streams from various flow regimes. Here I present three projects investigating how climate change, flow regime, and angler harvest may interact to affect Smallmouth Bass over the coming century. I first modeled present and future water temperatures and calculated growth rate potential for Smallmouth Bass from streams …

From Disaster To Sustainability: The Story Of The Pacific Groundfish, Matthew Richards

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper reviews the circumstances that led to the collapse of the Pacific groundfish fishery and the steps that fishery managers took to curb over-harvesting and bring the fishery back to sustainability. Fishery managers utilized various management tools such as a vessel buyback program, regulatory mechanisms, and market strategies to improve the available data on the fishery, improve safety for fishermen, and reduce harvest rates and overcapitalization. By employing a diverse range of measures, managers developed a system by with they successfully balanced conservation objectives and minimized adverse impacts to fishing communities. Overcapitalization and overharvest continue to degrade the health …

A Critical Analysis Of The Direct Effects Of Dredging On Fish, Amelia S. Wenger, Euan S. Harvey, Shaun K. Wilson, Christopher A. Rawson, Stephen J. Newman, Douglas Clarke, Benjamin J. Saunders, Nicola Browne, Michael J. Travers, Jennifer L. Mcilwain, Paul L A Erftemeijer, Jean-Paul A. Hobbs, Dianne L. Mclean, Martial Depczynski, Richard D. Evans

Fisheries Research Articles

Dredging can have significant impacts on aquatic environments, but the direct effects on fish have not been critically evaluated. Here, a meta-analysis following a conservative approach is used to understand how dredging-related stressors, including suspended sediment, contaminated sediment, hydraulic entrainment and underwater noise, directly influence the effect size and the response elicited in fish across all aquatic ecosystems and all life-history stages. This is followed by an in-depth review summarizing the effects of each dredging-related stressor on fish. Across all dredging-related stressors, studies that reported fish mortality had significantly higher effect sizes than those that describe physiological responses, although indicators …

Fit To Predict? Ecoinformatics For Predicting The Catchability Of A Pelagic Fish In Near Real-Time, Kylie L. Scales, Elliot L. Hazen, Sara M. Maxwell, Heidi Dewar, Suzanne Kohin, Michael G. Jacox, Christopher A. Edwards, Dana K. Briscoe, Larry B. Crowder, Rebecca L. Lewison, Steven J. Bograd

Biological Sciences Faculty Publications

The ocean is a dynamic environment inhabited by a diverse array of highly migratory species, many of which are under direct exploitation in targeted fisheries. The timescales of variability in the marine realm coupled with the extreme mobility of ocean-wandering species such as tuna and billfish complicates fisheries management. Developing ecoinformatics solutions that allow for near real-time prediction of the distributions of highly mobile marine species is an important step towards the maturation of dynamic ocean management and ecological forecasting. Using 25 years (1990-2014) of NOAA fisheries' observer data from the California drift gillnet fishery, we model relative probability of …

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

This report presents the results of a project undertaken by a group of Australia and United States based fishery compliance experts to assess and compare methods for measuring fisheries compliance outcomes that can be used to assess and compare the effectiveness of fishery enforcement and compliance assistance activities. This eight month project was requested in 2013 by Australia’s National Fisheries Compliance Committee (NFCC) as a way to provide fisheries compliance groups with improved methods for measuring and tracking the effectiveness of their activities and for justifying and managing their budgets.

Review Of Potential Fisheries And Marine Management Impacts On The South-Western Australian White Shark Population, S M. Taylor, J M. Braccini, R Mcauley, Wayne J. Fletcher

Fisheries Research Reports

Following five fatal incidents involving white sharks (Carcharodon carcharias) off the lower west coast of Western Australia between September 2011 and July 2012, as well as other highly-publicised non-fatal encounters with this species, in 2012 the State Government funded several new initiatives to better understand white sharks in Western Australia and the likely effectiveness of any community safety interventions in Western Australian waters.

Improving Efficiency In Generating Submissions And Consistency Of Outcomes For Marine Stewardship Council (Msc) Based Assessments, Warrick Fletcher, Daniel J. Gaughan, Lynda Bellchambers Dr

Fisheries Research Reports

The prevalence of fishery certification schemes and associated ecolabels has grown over the last ten years with numerous ecolabels now in the marketplace e.g. Friends of the Sea, Naturland, SAI Global Trust (Parkes et al. 2010, Washington and Ababouch 2011, Ward and Phillips 2013). However, one of the most prominent and well regarded, particularly by eNGOs, is the Marine Stewardship Council (MSC) (Gutiérrez et al. 2012, Ponte 2012, Bush et al. 2013, Ward and Phillips 2013) which accounts for greater than 10 % of annual global harvest of wild capture fisheries (MSC 2014b).

Double-Crested Cormorants, Brian S. Dorr, Kristi L. Sullivan, Paul D. Curtis, Richard Chipman, Russell D. Mccullough

Wildlife Damage Management Technical Series

The history of conflict between double-crested cormorants (Figure 1) and human interest in fisheries is long and convoluted. Following a low point in the 1970s, populations of cormorants expanded in North America, as did concerns about impacts on fisheries. By the late 1990s, natural resource agencies in 27 states reported losses of free-ranging fish stocks to cormorants. Agencies in 10 states, ranging from the Southwest to the Northeast, considered cormorant predation to be of moderate to major concern to fishery management.

Overall, double-crested cormorants are not major consumers of commercial and sportfish species. However, exceptions have been recorded at specific …

Growth And Reproduction Of Southern Flounder (Paralichthys Lethostigma) In The North-Central Gulf Of Mexico, Morgan Marie Corey

Master's Theses

Southern Flounder Paralichthys lethostigma is the most commonly harvested flatfish in the north-central Gulf of Mexico (GOM) and supports a major inshore recreational fishery, yet knowledge of the species’ life history is greatly limited. The objective of this research was to describe the growth and reproduction of Southern Flounder in the Mississippi stock. Fish were collected during September 2014 to March 2016 using primarily recreational fishing techniques. Otoliths (n = 313) were sectioned to estimate age, and multiple length-at-age models were fit to total length (TL, mm) and age estimate (y) data. Gonadal tissue samples (n = 221) …

Rapid Lateral Extraction Of Otoliths That Maintains The Integrity Of Fish Product To Improve Access To Catches And Reduce Potential Sampling Biases, Corey B. Wakefield, Dion K. Boddington, Stephen J. Davies

Fisheries Research Articles

The capacity to sample otoliths of fish from commercial, recreational, artisanal or subsistence catches can be constrained if the dissection process results in alterations to their external appearance and thus reduces its value and/or shelf life. There can also be significant biases incorporated into the collection of otolith samples if access is only granted relative to the size of the fish (i.e. if smaller fish are sold whole). To reduce such limitations, we herein describe a rapid and simple method of lateral otolith extraction that maintains the integrity of the fish product, and thus reduces potential biases in sample …

A Highly Sensitive Underwater Video System For Use In Turbid Aquaculture Ponds, Chin-Chang Hung, Shih-Chieh Tsao, Kuo-Hao Huang, Jia-Pu Jang, Hsu-Kuang Chang, Fred C. Dobbs

OES Faculty Publications

The turbid, low-light waters characteristic of aquaculture ponds have made it difficult or impossible for previous video cameras to provide clear imagery of the ponds' benthic habitat. We developed a highly sensitive, underwater video system (UVS) for this particular application and tested it in shrimp ponds having turbidities typical of those in southern Taiwan. The system's high-quality video stream and images, together with its camera capacity (up to nine cameras), permit in situ observations of shrimp feeding behavior, shrimp size and internal anatomy, and organic matter residues on pond sediments. The UVS can operate continuously and be focused remotely, a …

Seasonal Wind Patterns Around The Western Australian Coastline And Their Application In Fisheries Analysis, Alan Pearce, Anthony M. Hart, D. V. Murphy, Hannah Rice

Fisheries Research Reports

Monthly wind statistics have been derived for 23 weather stations along the Western Australian coast from Wyndham in the north-east of the state, down the west coast and around to Eucla in the south-east. The overall seasonal wind cycle at each site has been derived based on the 30-year period 1982 to 2011 (although a few stations had shorter records), and these show the major changes between the wind regimes along the Northwest Shelf, the west coast and the south coast.

Passage Route Survival And Behavior Of Juvenile Salmon At Priest Rapids Dam, Columbia River, Wa, Kyle B. Hatch

All Master's Theses

Columbia River hydropower is an economic mainstay of the Pacific Northwest. However, it is well known that the construction of hydropower dams has added anthropogenic pressure to Columbia River salmon populations. Juvenile salmon that pass through powerhouse turbines at large hydropower dams display higher mortality rates than salmon passing through alternative routes; thus at Priest Rapids Dam, a top-spill fish bypass was constructed as a safer alternate downstream passage. To investigate the efficacy of this new passage structure, an acoustic telemetry study was conducted in the spring of 2014 to determine the ability of the bypass to collect and safely …

Saffron Cod (Eleginus Gracilis) In North Pacific Archaeology, Megan A. Partlow, Eric Munk

All Faculty Scholarship for the College of the Sciences

Saffron cod (Eleginus gracilis) is a marine species often found in shallow, brackish water in the Bering Sea, although it can occur as far southeast as Sitka, Alaska. Recently, we identified saffron cod remains in two ca. 500-year-old Afognak Island midden assemblages from the Kodiak Archipelago. We developed regression formulae to relate bone measurements to total length using thirty-five modern saffron cod specimens. The archaeological saffron cod remains appear to be from mature adults, measuring 22–45 cm in total length, and likely caught from shore during spawning. Saffron cod may have been an important winter resource for Alutiiq people living …

The Reproductive Biology Of The Finetooth Shark, Carcharhinus Isodon, In The Northwest Atlantic Ocean, Amanda N. Brown

UNF Graduate Theses and Dissertations

Shark fisheries are a multimillion dollar industry in the United States and have significant contributions both recreationally and commercially. In order to maintain this industry, fisheries must be properly managed. An understanding of life history and reproduction is crucial in order to adequately manage shark fisheries. The finetooth shark, Carcharhinus isodon, is a member of the small coastal shark (SCS) fishery complex. It is found in Atlantic waters from South Carolina to Florida and throughout the Gulf of Mexico. This species has recently come under increased fishing pressure and has previously been overfished. New data is needed in order …

Fisheries Management Paper No.266 - Exmouth Gulf Prawn Managed Fishery Bycatch Action Plan 2014-2019. Version 1.0, Department Of Fisheries, Western Australia

Fisheries Management Papers

Bycatch is described as the part of the catch which is returned to the sea (usually referred to as non-retained or discarded) either because it has no commercial value or because legislative requirements preclude it being retained. Thus, this Bycatch Action Plan (BAP) includes unmarketable finfish and invertebrate species, along with endangered, threatened and protected (ETP) species, such as marine mammals, reptiles and some elasmobranchs.

It is Government policy to minimise bycatch in all commercial fisheries. This BAP details a program of actions to address bycatch issues in the Exmouth Gulf Prawn Managed Fishery (EGPMF), in accordance with the EGPMF …

Potential Eradication And Control Methods For The Management Of The Ascidian Didemnum Perlucidum In Western Australia, Julieta Muñoz, Justin I. Mcdonald

Fisheries Research Reports

In Western Australia, the invasive colonial ascidian Didemnum perlucidum was first detected in the Swan River Estuary in 2010 and subsequently recorded at multiple locations across the State. Ongoing research by the Department of Fisheries (the Department) indicates that this species exhibits strong seasonal changes in abundance. Although, D. perlucidum is able to reproduce sexually (larvae) and asexually (budding) year round, larvae density and settlement, and overall colony size significantly decreases during the colder months (winter). From a management point of view this period would present the best opportunity for an attempt at eradication or control of this species.

Angler Effort And Catch Within A Spatially Complex System Of Small Lakes, Christopher J. Chizinski, Dustin R. Martin, Kevin L. Pope, Tony J. Barada, Jeffrey J. Schuckman

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Spatial layout of waterbodies and waterbody size can affect a creel clerk’s ability to intercept anglers for interviews and to accurately count anglers, which will affect the accuracy and precision of estimates of effort and catch. This study aimed to quantify angling effort and catch across a spatially complex system of19 small (<100 ha) lakes, the Fremont lakes. Total (±SE) angling effort (hours) on individual lakes ranged from 0 (0) to 7,137 (305). Bank anglers utilized 18 of the 19 lakes, and their mean (±SE) trip lengths(hours) ranged from 0.80 (0.31) to 7.75 (6.75), depending on the waterbody. In contrast, boat anglers utilized 14 of the 19 lakes, and their trip lengths ranged from 1.39 (0.24) to 4.25 (0.71), depending on the waterbody. The most sought fishes, as indexed by number of lakes on which effort was exerted, were anything (17 of 19 lakes), largemouth bass Micropterus salmoides (15 of 19 lakes), and channel catfish Ictalurus punctatus (13 of 19 lakes). Bluegill Lepomis machrochirus, crappie Pomoxis spp., and largemouth bass were caught most frequently across the lakes, but catch rates varied considerably by lake. Of the1,138 parties interviewed, most parties (93%) visited …
