Crypt cells from the olfactory epithelium of the Pacific jack mackerel Trachurus symmetricus were characterized by light and electron microscopy and analyzed in dissociation with the patch-clamp technique in its cell-attached, perforated patch and normal whole-cell mode.

In situ target-strength measurements of Chilean jack mackerel (Trachurus symmetricus murphyi) collected with a scientific echosounder installed on a fishing vessel [PDF]
AbstractPeña, H. 2008. In situ target-strength measurements of Chilean jack mackerel (Trachurus symmetricus murphyi) collected with a scientific echosounder installed on a fishing vessel. – ICES Journal of Marine Science 65: 594–604. The use of commercial fishing vessels for scientific purposes has increased worldwide in the past 10 years.

BACTERIAL FORMATION OF HISTAMINE IN JACK MACKEREL (TRACHURUS SYMMETRICUS)
Peak histamine concentrations of 0.023, 0.031 and 0.027 g histamine/ 100 g muscle and maximal bacteria concentrations of 1.75, 1.59 and 0.423 g dry cells/100 g muscle were observed in muscles of jack mackerel stored at 25, 15 and 5C, respectively. Incubated fish homogenates suggest rate and transport limitations in histamine formation in muscle.

Análisis de las tasas de captura de jurel (Trachurus symmetricus) en la zona centro-sur de Chile (1987-1999) [PDF]
Catch per unit effort (CPUE) data from the jack mackerel fishery operating in central-south Chile and covering the period 1987-1999 are analyzed in order to detect changes in relative abundance. Two units for fishing effort were used to compute the catch rate: number of days outside port and the number of trips with capture. The fleet was classified in

Observation Bias in Metabarcoding. [PDF]
ABSTRACT DNA metabarcoding is subject to observation bias associated with PCR and sequencing, which can result in observed read proportions differing from actual species proportions in the DNA extract. Here, we amplify and sequence a mock community of known composition containing marine fishes and cetaceans using four different primer sets and a ...

Evaluation of the Nutritional Quality of the Five Commercial Fish Species From the Persian Gulf From Human Health Perspective. [PDF]
Based on the findings of this study, the best protein quality related to N. japonicus with an EAA index of 75.92. P. indicus has the best lipid quality due to the high ratio of ω‐3/ω‐6 (1.68) and PI (7.02). The abundant trace elements in all five fish species, K, Ca, Fe, and Zn, as well as these fish species, have good nutritional quality based on Na/K

Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2. [PDF]
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Climate Change Influences via Species Distribution Shifts and Century-Scale Warming in an End-To-End California Current Ecosystem Model. [PDF]
Climate change has wide‐ranging effects on marine ecosystems. Using an ecosystem model, we studied multiple effects of climate change on the fish and fisheries of the California Current. We find that both ocean warming and changes in species distributions will affect future trophic dynamics of this productive ecosystem, with consequences for fisheries ...

Continuing Long-Term Shifts in Larval Fish Phenology in the Southern California Current Ecosystem Are Matched by Rapid Advances in the North. [PDF]
Using two datasets with multiple decades of data, we find that larval fish in the northeast Pacific are, on average, appearing earlier in the year over time. These shifts can be partially explained by shifts in the seasonality of ocean temperature, upwelling, and prey abundance.

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]
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.
