Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska
Fisheries Oceanography, EarlyView.ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

VERDA: A Multisampler Tool for Mesopelagic Nets
Journal of Marine Science and Engineering, 2023 Different types and systems to discriminate plankton samples at different strata in the water column have been developed in recent decades. For sampling at sufficient depth, opening and closing zooplankton multinets are ideal because there is no ...

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)
Fisheries Oceanography, EarlyView.ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Journal of Marine Science and EngineeringDeep-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.

Exploration of the “larval pool”: development and ground-truthing of a larval transport model off leeward Hawai‘i [PDF]
PeerJ, 2016 Most adult reef fish show site fidelity thus dispersal is limited to the mobile larval stage of the fish, and effective management of such species requires an understanding of the patterns of larval dispersal.

Use of stereo camera systems for assessment of rockfish abundance in untrawlable areas and for recording pollock behavior during midwater trawls [PDF]
, 2010 We describe the application of two types of stereo camera systems in fisheries research, including the design, calibration, analysis techniques, and precision of the data obtained with these systems. The first is a stereo video system deployed by using

Differences in the trophic ecology of micronekton driven by diel vertical migration. [PDF]
, 2019 Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different ...

Journal of Fish Biology, EarlyView.Abstract The snakefish Trachinocephalus myops is an Atlantic species distributed in tropical and temperate coastal waters on sandy substrates. This study reports the validated record of an adult T. myops in the Azores archipelago caught by a fisherman at Faial Island.

Modeling of the Midwater Trawl Dynamical Behavior Based on R Language [PDF]
Proceedings of the 2015 International Conference on Mechatronics, Electronic, Industrial and Control Engineering, 2015 The midwater trawl is used widely in many oceanic fisheries. In this study, the midwater trawl dynamical behavior was simulated and modeled with the mathematical mechanic equations based on R language platform. A lump-mass and spring method was used to build the physical model.
