Acoustic Assessment of the Micronekton Community on the Chatham Rise, New Zealand, Using a Semi-Automated Approach

Frontiers in Marine Science, 2019
Micronekton are a key component of the pelagic food web of the Chatham Rise east of New Zealand. The Chatham Rise is an important fishing area for hoki (Macruronus novaezelandiae), New Zealand’s largest finfish fishery, and a predator on mesopelagic fish.

FEATURES OF FISH BEHAVIOR IN THE ACTION ZONE OF MIDWATER TRAWL

Vestnik of Astrakhan State Technical University. Series: Fishing industry, 2017
Researches in the field of behavior and distribution of fish at different stages of fishing were conducted using midwater trawls in order to increase fishing efficiency, subject to the fact that, besides fish behavior, parameters of midwater trawls and types of trawling affect the efficiency of trawling.

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

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)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
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 ...

Diversity Under Pressure: Long‐Term Genetic Decline in California's Central Valley Chinook Salmon ESA Listed Runs

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Chinook salmon in the Central Valley of California have notable intraspecific diversity because it is the only place where four distinct migration timings (Winter, Spring, Fall, Late‐fall) co‐occur. The Winter run is listed as Endangered and the Spring run is listed as Threatened under the Endangered Species Act. To quantify temporal changes in genetic

Study on Dynamic Characteristics and Fracture Failure of Rigid Truss Trawl System During Towing Process

Journal of Marine Science and Engineering
Deep-sea fisheries depend on various fishing methods, including trawling, purse seining, and longline fishing, among others. Studying the dynamic characteristics of trawling operations is essential for the trawl mechanism.

Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...
