Abstract: Genetic stock identification (GSI), an important tool for fisheries management that relies upon the ability to differentiate stocks of interest, can be difficult when populations are closely related.
Reduced disease in black abalone following mass mortality: phage therapy and natural selection.
Front Microbiol. 2014;5:78
Authors: Friedman CS, Wight N, Crosson LM, Vanblaricom GR, Lafferty KD
Black abalone, Haliotis cracherodii, populations along the NE Pacific ocean have declined due to the rickettsial disease withering syndrome (WS). Natural recovery on San Nicolas Island (SNI) of Southern California suggested the development of resistance in island populations.
Genotyping by sequencing resolves shallow population structure to inform conservation of Chinook salmon (Oncorhynchus tshawytscha).
Evol Appl. 2014 Mar;7(3):355-69
Authors: Larson WA, Seeb LW, Everett MV, Waples RK, Templin WD, Seeb JE
Recent advances in population genomics have made it possible to detect previously unidentified structure, obtain more accurate estimates of demographic parameters, and explore adaptive divergence, potentially revolutionizing the way genetic data are used to manage wild populations.
Secondary contact and changes in coastal habitat availability influence the nonequilibrium population structure of a salmonid (Oncorhynchus keta).
Mol Ecol. 2013 Dec;22(23):5848-60
Authors: Petrou EL, Hauser L, Waples RS, Seeb JE, Templin WD, Gomez-Uchida D, Seeb LW
Numerous empirical studies have reported lack of migration-drift equilibrium in wild populations. Determining the causes of nonequilibrium population structure is challenging because different evolutionary processes acting at a variety of spatiotemporal scales can produce similar patterns.
High-throughput sequencing and pathway analysis reveal alteration of the pituitary transcriptome by 17α-ethynylestradiol (EE2) in female coho salmon, Oncorhynchus kisutch.
Aquat Toxicol. 2013 Oct 15;142-143:146-63
Authors: Harding LB, Schultz IR, Goetz GW, Luckenbach JA, Young G, Goetz FW, Swanson P
Considerable research has been done on the effects of endocrine disrupting chemicals (EDCs) on reproduction and gene expression in the brain, liver and gonads of teleost fish, but information on impacts to the pituitary gland are still limited despite its central role in regulating reproduction.
Diversity of movements by individual anadromous coastal cutthroat trout Oncorhynchus clarkii clarkii.
J Fish Biol. 2013 Nov;83(5):1161-82
Authors: Goetz FA, Baker B, Buehrens T, Quinn TP
Wild, downstream-migrating cutthroat trout, Oncorhynchus clarkii clarkii, smolts and adults were captured at a weir in Big Beef Creek, Hood Canal, Washington, surgically implanted with acoustic tags and tracked to identify spring and summer movements using stationary receivers in order to test the assumption that the species moves little while in marine waters.
Integrating scientific guidance into marine spatial planning.
Proc Biol Sci. 2014;281(1781):20132252
Authors: Rassweiler A, Costello C, Hilborn R, Siegel DA
Marine spatial planning (MSP), whereby areas of the ocean are zoned for different uses, has great potential to reduce or eliminate conflicts between competing management goals, but only if strategically applied. The recent literature overwhelmingly agrees that including stakeholders in these planning processes is critical to success; but, given the countless alternative ways even simple spatial regulations can be configured, how likely is it that a stakeholder-driven process will generate plans that deliver on the promise of MSP?
Evolution of age and length at maturation of Alaskan salmon under size-selective harvest.
Evol Appl. 2014 Feb;7(2):313-22
Authors: Kendall NW, Dieckmann U, Heino M, Punt AE, Quinn TP
Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation. Spawning adults in many wild Alaskan sockeye salmon populations have become shorter at a given age over the past half-century, but their age composition has not changed.
Genetic and morphometric divergence in threespine stickleback in the Chignik catchment, Alaska.
Ecol Evol. 2014 Jan;4(2):144-56
Authors: Taugbøl A, Junge C, Quinn TP, Herland A, Vøllestad LA
Divergent selection pressures induced by different environmental conditions typically lead to variation in life history, behavior, and morphology. When populations are locally adapted to their current environment, selection may limit movement into novel sites, leading to neutral and adaptive genetic divergence in allopatric populations.
Injuries from non-retention in gillnet fisheries suppress reproductive maturation in escaped fish.
PLoS One. 2013;8(7):e69615
Authors: Baker MR, Swanson P, Young G
Exploitation of fisheries resources has unintended consequences, not only in the bycatch and discard of non-target organisms, but also in damage to targeted fish that are injured by gear but not landed (non-retention). Delayed mortality due to non-retention represents lost reproductive potential in exploited stocks, while not contributing to harvest.
