Environmental DNA reveals temporal variation in mesophotic reefs of the Humboldt upwelling ecosystems of central Chile: Toward a baseline for biodiversity monitoring of unexplored marine habitats. [PDF]

Ecol Evol
Here, environmental DNA (eDNA) was used to characterize temperate mesophotic reef ecosystems (TMREs) along the central Chilean coast, shedding light on their biodiversity. Through eDNA analysis at different depths and seasons, we identified 42 phyla and 237 orders, with Arthropoda, Bacillariophyta, and Chordata being the most diverse.

Population structure and demographic history of the gastropod Thaisella chocolata (Duclos, 1832) from the Southeast Pacific inferred from mitochondrial DNA analyses

Ecology and Evolution, Volume 12, Issue 9, September 2022., 2022
Here we provide a comprehensive phylogeographical study of a species distributed along the Southeast Pacific coastal region by analyzing the endemic gastropod Thaisella chocolata (Duclos, 1832). Sequencing of mitochondrial cytochrome c oxidase subunit 1 (CO1) and 16S rRNA revealed strikingly high haplotypic nucleotide and genetic diversity but a lack ...

Tandem mass tag–based proteomics analysis of protein changes in the freezing and thawing cycles of Trachurus murphyi

Journal of Food Science, Volume 87, Issue 9, Page 3938-3952, September 2022., 2022
Abstract We investigated the proteome variations in Trachurus murphyi with different cycles of freezing and thawing (FT) under frozen storage. A total of 2,482 proteins were assessed quantitatively, of which 269 proteins were recognized as differential abundance proteins during the second FT cycle until the eighth FT cycle.

Fatty Acid Profile, Physicochemical Composition, and Sensory Properties of Atlantic Salmon Fish (Salmo salar) during Different Culinary Treatments

Journal of Food Quality, Volume 2022, Issue 1, 2022., 2022
This study was conducted to assess the effects of boiling, steaming, and oven‐cooking on the fatty acid profile, physicochemical composition, and sensory properties of Atlantic salmon fish. The protein content of steamed (18.90%) and oven‐cooked (20.59%) salmon was significantly higher than that of boiled (16.69%) and raw fish (14.73%). Analysis of the

Spatiotemporal variability in the occurrence of juvenile Japanese jack mackerel Trachurus japonicus along coastal areas of the Kuroshio Current

Fisheries Oceanography, Volume 30, Issue 5, Page 569-583, September 2021., 2021
Abstract To understand the population structure of the Japanese jack mackerel Trachurus japonicus in coastal areas adjacent to the Kuroshio Current (referred to as the “CAK”), we analyzed size composition and commercial landing data of juvenile fish in these areas for the period 2005–2015.

Remote Sensing of the Subtropical Front in the Southeast Pacific and the Ecology of Chilean Jack Mackerel Trachurus murphyi

Fishes, 2023
The Subtropical Front (STF) plays a key role in the ecology of Chilean jack mackerel Trachurus murphyi. Nonetheless, there are few remote sensing studies of the STF in the open Southeast Pacific, and almost all of them have been conducted by satellite ...

Bomb Radiocarbon, Otolith Daily Increments and Length Modes Validate Age Interpretations of Chilean Jack Mackerel (Trachurus murphyi)

Frontiers in Marine Science, 2022
Ages of Chilean jack mackerel (Trachurus murphyi) in the southern Pacific Ocean were validated using three methods: 1) daily microincrement readings in sagittal otoliths of young-of-the year (YOY) fish to validate the first annulus; 2) modal progression ...

Dinámica trófica del jurel (Trachurus symmetricus murphyi) en el norte de Chile [PDF]

Investigaciones marinas, 2002
The trophic dynamic of jack mackerel Trachurus symmetricus murphyi, caught off the coast of northern Chile, between the spring 1993 and winter 1994, is described. Relative importance of prey taxa, identification of ontogenetic trophic units and prey selectivity by size was evaluated.
