First Hybrid Genome Assembly of the Teleost Fish Red Cusk-Eel (Genypterus chilensis) from Oxford Nanopore and Illumina Reads: Comparative Genomic Analysis of Genypterus Species and Long Non-Coding RNA Tissue-Specific Expression

Fishes
The red cusk-eel (Genypterus chilensis) is an endemic Chilean teleost fish of significant importance to fisheries and aquaculture; however, no reference genome is available for this species. In this study, we present the first hybrid genome assembly of G.

Impacts of Global Warming on Quality of Male Fishes: Evidence From A Meta‐Analysis of Temperature Effects on Sperm Motility Kinematics

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...

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

EFSA Journal, Volume 22, Issue 11, November 2024.
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.

Impact of mercury released from permafrost on food safety in Switzerland

Food Risk Assess Europe, Volume 2, Issue 4, October 2024.
ABSTRACT Climate change has caused the permafrost to thaw, releasing the previously sequestered mercury into the environment. Mercury has the ability to convert to methylmercury, a bioaccumulative neurotoxin. Exposure occurs in humans through the ingestion of contaminated food and it is associated with adverse health effects.

Morphology and ultrastructure of pink cusk-eel (Genypterus blacodes, Schneider 1801) spermatozoa by scanning and transmission electron microscopy

Tissue and Cell, 2018
In this study, the morphology and ultrastructure of Genypterus blacodes spermatozoa were characterized through scanning and transmission electron microscopy. Findings revealed that the G. blacodes spermatozoa can be differentiated into three major parts: a spherical head without an acrosome (typical for externally fertilizing fish), a short mid-piece ...
