Acoustic monitoring reveals the times and tides of harbor porpoise (Phocoena phocoena) distribution off central Oregon, U.S.A.

open access: yesMarine Mammal Science, Volume 35, Issue 1, Page 164-186, January 2019., 2019
Abstract Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species from future coastal development.

Short‐Term Pain and Long‐Term Gain: Using Phased‐In Minimum Size Limits to Rebuild Stocks—the Pacific Bluefin Tuna Example

open access: yesTransactions of the American Fisheries Society, Volume 147, Issue 6, Page 1015-1029, November 2018., 2018
Abstract Like many stocks, the Pacific Bluefin Tuna Thunnus orientalis has been considerably depleted. High exploitation rates on very young fish have reduced the spawning stock biomass (SSB) to 2.6% of the unexploited level. We provide a framework for exploring potential benefits of minimum size regulations as a mechanism for rebuilding stocks, and we

Fish Larvae Response to Biophysical Changes in the Gulf of California, Mexico (Winter‐Summer)

open access: yesJournal of Marine Sciences, Volume 2013, Issue 1, 2013., 2013
We analyzed the response of fish larvae assemblages to environmental variables and to physical macro‐ and mesoscale processes in the Gulf of California, during four oceanographic cruises (winter and summer 2005 and 2007). Physical data of the water column obtained through CTD casts, sea surface temperature, and chlorophyll a satellite imagery were used

Hyperostosis in Fishes: An Update With New Species Records

open access: yesJournal of Morphology, Volume 285, Issue 11, November 2024.
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

Genetic study of populations of two species of genus <i>Trachurus: T. lathami and T. symmetricus</i>

open access: yesJournal of Renewable Natural Resources
We conducted a population genetics study of two species of the genus Trachurus: T. symmetricus and T. lathami by analyzing the genetic structure of each species. This was performed by enzymes and mitochondrial DNA electrophoresis in starch, polyacrylamide and agarose respectively to establish the degree of relationship between species. The results show
