Assessing the reliability of species distribution models in the face of climate and ecosystem regime shifts: Small pelagic fishes in the California Current System

Frontiers in Marine Science, 2022
Species distribution models (SDMs) are a commonly used tool, which when combined with earth system models (ESMs), can project changes in organismal occurrence, abundance, and phenology under climate change.

Preliminary results of the empirical validation of daily increments in otoliths of jack mackerel Trachurus symmetricus murphyi (Nichols, 1920) marked with oxytetracycline

Scientia Marina, 2003
The frequency of microincrement formation in sagittae otoliths of jack mackerel Trachurus symmetricus was validated using experiments on captive fish. Adult jack mackerel were injected with a dose of 100 mg of oxytetracycline/kg of fish.

Spiral valve parasites of blue and common thresher sharks as indicators of shark feeding behaviour and ecology

Journal of Fish Biology, Volume 97, Issue 2, Page 354-361, August 2020., 2020
Abstract This study documented the parasite faunas of the spiral valves of blue sharks Prionace glauca (L. 1758) and common thresher sharks Alopias vulpinus (Bonnaterre, 1788) caught in the California Current Large Marine Ecosystem (CCLME) north of the Mexican border.

Efficacy of metabarcoding for identification of fish eggs evaluated with mock communities

Ecology and Evolution, Volume 10, Issue 7, Page 3463-3476, April 2020., 2020
We examine the effectiveness of using metabarcoding methods on mock communities of known fish egg DNA using six mock communities with known ratios of species and two samples from a large field collection of fish eggs. We examine the ability of our metabarcoding methods to detect species and relative proportion of species identified in each mock ...

Long-term changes in the mean trophic level of Central Chile fishery landings

Scientia Marina, 2005
We explore long-term changes in the mean trophic level (TLm) of Central Chile fishery landings, using a 21 years data series (1979-1999) of official landings (Chilean Fisheries Service) of 16 species that comprise about 95% of total landing, and their ...

First Record of Anisakis sp. Third-Stage Larvae (Nematoda) Occurrence, as a Human Risk, in Pacific Jack Mackerel from a Fish Processing and Packaging Plant in the North of Iran

Journal of BioScience and Biotechnology, 2023
Purpose: This research was performed with the aim of hygienic tracking for fish-borne parasitic contamination imported by Jack mackerel fish from certain parts of the world in a fish processing unit during a health inspection in the northern region of ...

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

Marine 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

Transactions 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)

Journal 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
