Fish Protein Hydrolysate from Sulfated Polysaccharides Extraction Residue of Tuna Processing By‐Products with Bioactive and Functional Properties

Global Challenges, Volume 7, Issue 4, April 2023., 2023
This study proves that the ethanol residue remaining during polysaccharide extraction from skipjack tuna by‐products can be a source for parallel extraction of protein hydrolysates with good bioactivity and functional properties and can be employed as a natural source of antioxidant and antibacterial compounds that can be used in the food and ...

A Comprehensive Evaluation of Taxonomic Classifiers in Marine Vertebrate eDNA Studies. [PDF]

Mol Ecol Resour
ABSTRACT Environmental DNA (eDNA) metabarcoding is a widely used tool for surveying marine vertebrate biodiversity. To this end, many computational tools have been released and a plethora of bioinformatic approaches are used for eDNA‐based community composition analysis.

Species identification in fish meal from urban fisheries biomass with DNA metabarcoding analysis

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 562-571, December 2022., 2022
Fish species constructing fish meal (FM) made from urban fisheries biomass, which is fisheries by‐products collected downstream in the seafood supply chain were detected with a DNA metabarcoding method. 81–122 species were detected in the FM, and fish species indicated as Critically Endangered (CR) or Endangered (EN) on the International Union for ...

Focusing on what matters most: Evaluating multiple challenges to stability in recreational fisheries

Fish and Fisheries, Volume 23, Issue 6, Page 1418-1438, November 2022., 2022
Abstract Recreational fisheries were traditionally theorized to self‐regulate in a sustainable feedback loop in which recreational anglers moderate their fishing effort in response to population declines. However, several mechanisms are hypothesized to break down this self‐regulatory process, including recruitment variability and depensatory population

Distribution, Feeding Habits, and Growth of Chub Mackerel, Scomber japonicus, Larvae During a High-Stock Period in the Northern Satsunan Area, Southern Japan

Frontiers in Marine Science, 2021
To evaluate the importance of the northern Satsunan area in southern Japan as a spawning and nursery ground for chub mackerel (Scomber japonicus), we investigated the early life history characteristics (e.g., larval distribution, feeding habits, and ...

Impact of germ cell ablation on the activation of the brain–pituitary–gonadal axis in precocious Atlantic salmon (Salmo salar L.) males

Molecular Reproduction and Development, Volume 89, Issue 10, Page 471-484, October 2022., 2022
Abstract The germ cells are essential for sexual reproduction by giving rise to the gametes, but the importance of germ cells for gonadal somatic functions varies among vertebrates. The RNA‐binding dead end (Dnd) protein is necessary for the specification and migration of primordial germ cells to the future reproductive organs.

DNA metabarcoding reveals a broad dietary range for Tasmanian devils introduced to a naive ecosystem

Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022
Top‐order carnivores are essential for maintaining ecosystem stability and biodiversity. We used a metabarcoding and next‐generation sequencing approach to quantify the diet of Tasmanian devils introduced to Maria Island, Tasmania, a site outside the species’ native range.

Development of species‐specific multiplex real‐time PCR assays for tracing the small pelagic fishes of North Pacific with environmental DNA

Environmental DNA, Volume 4, Issue 3, Page 510-522, May 2022., 2022
Multiplex qPCR assays for 6 types of small pelagic fishes were developed to measure environmental DNA from open water to infer the occurrence of fish schools. The method sensitivity and specificity were tested using field samples obtained from fisherman's set nets.

Migration and spawning behavior of the greater amberjack Seriola dumerili in eastern Taiwan

Fisheries Oceanography, Volume 31, Issue 1, Page 1-18, January 2022., 2022
Abstract Greater amberjack (Seriola dumerili) is an important fishery resource with a circumglobal distribution from tropical to temperate waters. Here, we investigated the spawning migration and habitat utilization of S. dumerili in the East China Sea (ECS).
