Development of a polymerase chain reaction (PCR)-based genetic sex identification method in the chub mackerel Scomber japonicus and blue mackerel S. australasicus

open access: yes, 2021
Chub mackerel Scomber japonicus and blue mackerel S. australasicus have become important aquaculture target species in Japan. For an efficient and stable aquaculture production of mackerels, it is desirable to work with a female-biased broodstock and ...

Helminth parasites of the Atlantic chub mackerel, Scomber colias Gmelin, 1789 from Canary Islands, Central North Atlantic, with comments on their relations with other Atlantic regions [PDF]

open access: yes, 2011
Eleven parasite taxa were found infecting 68 Atlantic chub mackerel, Scomber colias Gmelin, 1789 from the Canary Islands, Central North Atlantic. The most abundant parasites were the gill monogenean Pseudokuhnia minor (P = 54.4%), larval anisakid ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

open access: yesJournal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Veštački mrest klena (Leuciscus cephalus, linnaeus, 1758) [PDF]

open access: yes, 2015
Chub Leuciscus cephalus (L.) is a rheophilic cyprinid which prefers lotic habitat conditions, shallow water (0.1–0.3 m) and gravel banks with moderate to high water flow (0.15–0.75m s–1) for spawning.

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.
