Measuring Maine’S Marine Economy, Brian Roach, Jonathan Rubin, Charles Morrris 2016 University of Maine

Measuring Maine’S Marine Economy, Brian Roach, Jonathan Rubin, Charles Morrris

Jonathan Rubin

Even though Maine’s new license plate no longer features the lobster, the ocean remains central to Maine’s identity and to its economy. As the authors point out, Maine has more than 4,500 miles of coastline and more than 4,600 islands over one acre in size. For many who live here, their way of life is tied to the sea; for many who visit Maine, their stay is tied to the sea. Despite such prominence, it has been difficult to accurately assess the importance of Maine’s marine economy. In part, this is because there clear definition ...


Fisheries Management With Stock Growth Uncertainty And Costly Capital Adjustment, Rajesh Singh, Quinn Weninger, Matthew Doyle 2016 Iowa State University

Fisheries Management With Stock Growth Uncertainty And Costly Capital Adjustment, Rajesh Singh, Quinn Weninger, Matthew Doyle

Quinn Weninger

We develop a dynamic model of a fishery which simultaneously incorporates random stock growth and costly capital adjustment. Numerical techniques are used to solve for the resource-rent-maximizing harvest and capital investment policies. Capital rigidities bring diminishing marginal returns to the current period harvest, and introduce an incentive to smooth the catch over time. With density-dependent stock growth, however, catch smoothing increases stock variability resulting in reduced average yields. The optimal management policy balances the catch smoothing benefits against yield loss. We calibrate the model to the Alaskan pacific halibut fishery to demonstrate the main insights.


Bioeconomies Of Scope And The Discard Problem In Multiple-Species Fisheries, Rajesh Singh, Quinn Weninger 2016 Iowa State University

Bioeconomies Of Scope And The Discard Problem In Multiple-Species Fisheries, Rajesh Singh, Quinn Weninger

Quinn Weninger

We consider the problem of multi-species fisheries management when targeting individual species is costly and at-sea discards of fish by fishermen are unobserved by the regulator. Stock conditions, ecosystem interaction, technological specification, and relative prices under which at-sea discards are acute are identified. A dynamic model is developed to balance ecological interdependencies among multiple fish species, and scope economies implicit in a costly targeting technology. Three regulatory regimes, species-specific harvest quotas, landing taxes, and revenue quotas, are contrasted against a hypothetical sole-owner problem. An optimal plan under all regimes precludes discarding. For both very low and very high levels of ...


Growth And Reproduction Of Southern Flounder (Paralichthys Lethostigma) In The North-Central Gulf Of Mexico, Morgan Marie Corey 2016 University of Southern Mississippi

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) were preserved for histological ...


Development Of Genomic Resources For The Evaluation Of Red Snapper, An Emerging Species Candidate For Marine Aquaculture And Stock Enhancement, Adrienne Elise Norrell 2016 University of Southern Mississippi

Development Of Genomic Resources For The Evaluation Of Red Snapper, An Emerging Species Candidate For Marine Aquaculture And Stock Enhancement, Adrienne Elise Norrell

Master's Theses

The northern red snapper (Lutjanus campechanus) is a highly targeted reef fish candidate for marine aquaculture and stock enhancement in the southern United States. This work aimed to develop genomic resources for the genetic management of aquaculture programs and to investigate population structure using high-throughput sequencing technologies. Eighty-four new microsatellite markers were developed through screening of Illumina paired-end sequencing reads. Microsatellite loci and Single Nucleotide Polymorphisms (SNPs) generated through Restriction Site Associated DNA (RAD) sequencing were assayed in 5 outbred full-sib families to construct a high-density linkage map of the red snapper genome. The map consists of 7,964 markers ...


Short-Term Water Potential Fluctuations And Eggs Of The Red-Eared Slider Turtle (Trachemys Scripta Elegans), John K. Tucker, Gary L. Paukstis, Fredric J. Janzen 2016 Illinois Natural History Survey

Short-Term Water Potential Fluctuations And Eggs Of The Red-Eared Slider Turtle (Trachemys Scripta Elegans), John K. Tucker, Gary L. Paukstis, Fredric J. Janzen

Fredric Janzen

We exposed eggs of the red-eared slider turtle (Trachemys scripta elegans) to short duration (i.e., 48 hours) changes in water potential at two embryonic ages (20 and 40 days). Survivorship to hatching did not differ by substrate water potential or among treatments. Net change in egg mass, a measure of net water exchange between the egg and substrate, was affected by treatments. However, treatments had no effect on hatchling mass, carcass mass, yolk mass, or incubation period. Eggs and embryos are able to exploit beneficial short-term increases in water potential and withstand adverse ones.
