Preventive Management of Cannibalism by Size‐Grading in Juvenile Red‐Spotted Grouper (Epinephelus akaara)

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT This study aimed to quantify the cannibal‐prey size relationship using morphometric regression models and to establish an effective size‐grading strategy to prevent cannibalism. A total of 15,000 juveniles at 73 days post‐hatching (DPH) were reared in a circular tank (approximately 12 tons) operated under a flow‐through seawater system at 26.0

Trade and Management: Exclusive Economic Zones and the Changing Japanese Surimi Market [PDF]

open access: yes, 1994
The United States' increasing competitive advantage in international seafood trade in Alaska walleye pollock. Theragra chalcogramma, has contributed to higher prices for surimi-based goods and structural changes in seafood production and trade in Japan ...

Medium‐Range Predictability of the Wintertime Bering Sea Ice Edge Using Linear Inverse Modeling

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Beginning in autumn, sea ice expands into the southern Bering Sea, where it remains until spring. In winter, some commercial stocks, particularly crabs, thrive in ice‐infested areas, necessitating short‐lead forecasts of the ice edge for fishers.

Temporal and spatial distribution and abundance of flathead sole (Hippoglossoides elassodon) eggs and larvae in the western Gulf of Alaska [PDF]

open access: yes, 2005
Data from ichthyoplankton surveys conducted in 1972 and from 1977 to 1999 (no data were collected in 1980) by the Alaska Fisheries Science Center (NOAA, NMFS) in the western Gulf of Alaska were used to examine the timing of spawning, geographic ...

Body Condition as a Shared Response to Environment in a Commercially Important Demersal Fish Assemblage

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 264-284, March 2026.
ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

Use of stereo camera systems for assessment of rockfish abundance in untrawlable areas and for recording pollock behavior during midwater trawls [PDF]

open access: yes, 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

The Potential Sex Determination Genes, Sox9a and Cyp19a, in Walleye Pollock (Gadus Chalcogrammus) Are Influenced by Water Temperature

open access: yesJournal of Marine Science and Engineering, 2020
Our aim was to study the relationship between the sex-determining genes, sox9a and cyp19a, and water temperature in Gadus chalcogrammus. We assessed the sex ratio based on the expression levels of sox9a and cyp19a at different water temperatures (5, 8 ...

Long‐Term Changes in Dominant Fisheries Species and Their Relationship With Surface Oceanic Conditions in the Waters Around the Korean Peninsula From 1980 to 2019

open access: yesFisheries Oceanography, Volume 35, Issue 2, Page 267-284, March 2026.
ABSTRACT The waters surrounding Korea are an economically–ecologically important region due to their high fishery productivity and role as seasonal migratory routes for the spawning and growth of commercially valuable species. We evaluated temporal changes in dominant fisheries species in encompassing large marine ecosystem (LME) areas 47, 48, and 50 ...

Regional variation in the annual feeding cycle of juvenile walleye pollock (Theragra chalcogramma) in the western Gulf of Alaska [PDF]

open access: yes, 2011
Juvenile fish in temperate coastal oceans exhibit an annual cycle of feeding, and within this cycle, poor wintertime feeding can reduce body growth, condition, and perhaps survival, especially in food-poor areas.

Strike Behavior and Behavioral Responses to Retrieval by Northern Pike (Esox lucius) During Ice Angling

open access: yesFisheries Management and Ecology, Volume 33, Issue 1, Page 119-133, February 2026.
ABSTRACT Behavior of fish during catch and release has not been well studied despite its potential importance for fish conservation and welfare. We used underwater video footage to examine behaviors of ice‐angled northern pike (Esox lucius) during approach and retrieval.
