Observation Bias in Metabarcoding. [PDF]

Mol Ecol Resour
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]

Food Sci Nutr
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]

EFSA J
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]

Glob Chang Biol
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]

Glob Chang Biol
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]

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.

Characterizing habitat suitability for a central-place forager in a dynamic marine environment. [PDF]

Ecol Evol, 2018
We combine satellite telemetry, near‐real‐time remotely sensed oceanography, and statistical models to explore how lactating California sea lions (Zalophus californianus, n = 72) may select habitat and respond to environmental variability over broad spatial and temporal scales within the California Current System.

BACTERIAL FORMATION OF HISTAMINE IN JACK MACKEREL (TRACHURUS SYMMETRICUS)

Journal of Food Processing and Preservation, 2004
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.

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.
