Tolerance of Egg and Yolk‐Sac Larval Yellowfin Sole (Limanda aspera) to Ocean Warming and Acidification

Fisheries Oceanography, EarlyView.
ABSTRACT Yellowfin sole (Limanda aspera) support the largest flatfish fishery in the world and contribute substantially to the eastern Bering Sea (EBS) flatfish catch. The EBS has been warming and acidifying, trends that are expected to intensify into the future.

Stage‐Specific Indicators of Northern Yellowtail Rockfish (Sebastes flavidus) Recruitment in the California Current Ecosystem

Fisheries Oceanography, EarlyView.
ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

Performance of pulse trawling compared to conventional beam trawling

, 2006
A series of nine fishing trips with on board observers were carried out on MFV UK153 (PT1) and two beam trawlers (BT1, BT2) of comparative engine power and size to appraise the performance of pulse beam v.s. conventional tickler chain beam trawls. The main conclusions from this study are: 1.

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

Fisheries 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

Atmospheric CO2 emissions and ocean acidification from bottom-trawling

Frontiers in Marine Science
Trawling the seafloor can disturb carbon that took millennia to accumulate, but the fate of that carbon and its impact on climate and ecosystems remains unknown.

Trawl-kite

, 2023
Denne bacheloroppgaven utforsker designprosessen for et trål-kitesystem, en spennende fremgang innen marinteknologi. Trål-kite er konseptualisert som et autonomt system med mål om å gjøre bunntråling, en betydelig del av de globale fiskeriene, mer bærekraftig. Dette innovative systemet er utformet som en kite, utstyrt med hydrofoiler for løftgenerering,

Temporal Changes in a Tropical Nekton Assemblage and Performance of a Prawn Selective Gear [PDF]

, 1995
The temporal variation of components of a moderately diverse (H=1.46) tropical estuarine fish assemblage (long. 146°30'E, lat. 8°45'S) was directed by salinities that had been determined by local oceanographic and probably topographic conditions.

Effects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery

Fisheries Oceanography, EarlyView.
ABSTRACT Global climate change is intensifying ocean deoxygenation, particularly in eastern boundary current systems such as the California Current. This study investigates the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast.

Effects of Body Size and Environmental Region on the Nutritional Value of Small Pelagic Species in the California Current

Fisheries Oceanography, EarlyView.
ABSTRACT We evaluated the effects of regional environment and body size on the nutritional traits of five small pelagic species differing in habitat use, feeding behavior, and importance as prey for top predators in the California Current Large Marine Ecosystem (CCLME).

A Brief History of Bycatch Management Measures for Eastern Bering Sea Groundfish Fisheries [PDF]

, 1997
Bycatch management measures instituted for groundfish fisheries of the eastern Bering Sea have focused on reducing the incidental capture and injury of species traditionally harvested by other fisheries.
