Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses ...

Fishing Technologies: Specification And Estimation, Quinn Weninger, Larry Perruso, Helle Bunzel
Economics Working Papers
This paper consistently estimates the structural properties of a multiple-species fishing technology. Our approach overcomes two ubiquitous features of fisheries data generating processes that invalidate classical ordinary least squares estimators: (1) unobservability, by the researcher, of the in situ fish stock and its effect on productivity, and (2) endogenous production decisions that vary with fishermen’s private information about stock abundance and other economic variables. Our estimations obtain consistency by exploiting the timing of production decisions and the information available to fishermen when endogenous production scale and scope, i.e., targeting of individual species’, decisions are made. Our estimator adopts ...

Legacy Habitat Suitability Of Eastern Oysters (Crassostrea Virginica) In Louisiana: A Prelude To Mississippi River Delta Freshwater Diversions, Tasia Mv Denapolis
University of New Orleans Theses and Dissertations
The Louisiana oyster industry is greatly impacted by freshwater and sediment diversions that are part of the effort to restore the state’s coastline. A habitat suitability index (HSI) proposes species-habitat relationships that can be instrumental in creating impact assessments and suitability predictions for management as new diversions are implemented. An oyster (Crassostrea virginica) HSI was developed using three variables crucial to oyster sustainability: average annual salinity, minimum monthly salinity, and average salinity during the spawning season. These Legacy HSI visualizations show annual fluctuations in the distribution of zones suitable for oyster cultivation prior to proposed diversions in Pontchartrain and ...

Multi-Metric Conservation Assessment For The Imperiled Clinch Dace, Michael James Moore, Donald J. Orth, Eric M. Hallerman
Southeastern Fishes Council Proceedings
Planning frameworks allow managers to spatially prioritize actions to promote species conservation. Traditional aquatic conservation planning frameworks are often organized at the ecological community or ecosystem level, which often neglect imperiled taxa occupying species-poor assemblages. In this study, we develop a multi-metric conservation assessment for the 15 geographically distinct candidate conservation areas (CCAs) occupied by the imperiled Clinch Dace (Chrosomus sp. cf. saylori). Clinch Dace habitat is threatened by anthropogenic landscape alterations, especially for coal mining and timber harvest. Our framework used four metrics to assess the conservation value of each subpopulation of Clinch Dace namely: “habitat condition”, “viability”, conservation ...

Managing Lake Fertility Within The Guidelines Of A Nutrient Management Plan And Based On Algal Nutrient Limitation, Bradley J. Austin, J. Thad Scott, Brian E. Haggard
Technical Reports
The specific objectives were to first, monitor nutrients, algal biomass, and water clarity in lakes Cove, Spring, and Wedington. Second, evaluate whether algal growth in each of the lakes was limited by N, P, or both N and P. This research was conducted to help USFS better manage lake fertilization to maximize algal growth and improve the fisheries within these lakes.

Biological Sciences Faculty Publications
The extinction risk of sharks, rays and chimaeras is higher than that for most other vertebrates due to low intrinsic population growth rates of many species and the fishing intensity they face. The Arabian Sea and adjacent waters border some of the most important chondrichthyan fishing and trading nations globally, yet there has been no previous attempt to assess the conservation status of species occurring here. Using IUCN Red List of Threatened Species Categories and Criteria and their guidelines for application at the regional level, we present the first assessment of extinction risk for 153 species of sharks, rays and ...

An Evaluation Of Sciaenid Growth In The Gulf Of Mexico, Shane Flinn
LSU Master's Theses
Growth models estimate life history parameters that are used in the management of fisheries stocks. The most commonly used growth model in fisheries is the von Bertalanffy growth model (VBGM), yet it has been shown to provide a poor fit for length-at-age data of some species and other models exist. I reviewed 196 peer-reviewed age and growth studies and 50 NOAA stock assessments to examine temporal trends in the use of growth models and model selection in fisheries. I found that the use of multi-model frameworks has increased since the year 2000 and information theoretic approaches are replacing goodness-of-fit and ...

Expanding Instream Flows To Protect Ecosystems In Overallocated River Basins, Belize A. Lane, David E. Rosenberg
Reports
Utahns are expressing a rapidly growing interest in protecting and enhancing instream flows for outdoor recreation and environmental benefits (Endter-Wada et al. 2015). However, many Utah rivers are already over-allocated for agricultural, municipal, hydropower and other water uses, making it difficult to procure additional water for instream flows. ‘Use it or lose it’ western water law and mentality encourages Utahns to use water rather than return it to rivers and ecosystems.
This briefing reviews existing instream flow practices allowed by the Utah water rights system and the challenges to implementation. We suggest key technical and legislative opportunities within and outside ...
The Effect Of Shelter Availability On Foraging In Atlantic Salmon (Salmo Salar),

The Effect Of Shelter Availability On Foraging In Atlantic Salmon (Salmo Salar), Christian A. Therrien
Electronic Thesis and Dissertation Repository
Shelter is an environmental feature that provides protection from danger and its use is an important anti-predator behavior for juvenile Atlantic salmon (Salmo salar). However, how shelter availability influences the foraging of these fish in the wild is not well documented. I predicted that juvenile Atlantic salmon would alter their foraging behavior in a low shelter environment and that this effect would differ between individuals from two populations that are targeted for reintroduction into Lake Ontario. I measured the foraging activity of juvenile Atlantic salmon from the two populations while they were held in pens in a Lake Ontario tributary ...

Irondequoit Bay Fish Stock Assessments 2005-2015, Matthew J. Sanderson
Technical Reports
Warm water fisheries assessments using standard gangs of gill nets were conducted in Irondequoit Bay in September of 2005, 2010, and 2015. In addition, a nighttime electrofishing survey was conducted in June 2009. The surveys were conducted to 1) assess the fish community; 2) determine the contribution of stocked fingerlings to the walleye (Sander vitreus) population; 3) estimate population characteristics of walleye, northern pike (Esox lucius), yellow perch (Perca flavescens), and largemouth bass (Micropterus salmoides), 4) compare fish community structure to statewide surveys; and 5) guide the development of appropriate management recommendations. From 2005 to 2015 overall gill net catch ...

EXECUTIVE SUMMARY
1 July 2017 – 30 June 2018
The Trawl Survey provides crucial data to state, regional, and national fisheries management agencies, including the Virginia Marine Resources Commission (VMRC), the Atlantic States Marine Fisheries Commission (ASMFC), the Mid-Atlantic Fisheries Management Council (MAFMC), and the National Marine Fisheries Service (NMFS). The MAFMC recognizes the juvenile trawl survey as one of the key predictors of Summer Flounder recruitment. Annual indices of juvenile abundance have been generated from trawl survey data for species of key recreational, ecological, and commercial importance in the Virginia portion of Chesapeake Bay. These include Spot, Atlantic Croaker, Weakfish ...
