Prospects for the pink salmon fishery in the Russian waters of the Bering and Okhotsk Seas in 2024 based on the analysis of the juveniles trawl surveys aboard RV TINRO and RV Professor Kaganovsky in the fall of 2023

Известия ТИНРО
Trawl surveys on juvenile pink salmon in fall season provide crucial information for forecasting their returns because of lower mortality of the juveniles in this season compared to their mortality during downstream migration in rivers or in the early ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Analysis of the salmon fishery in Khabarovsk Region in 2023

Известия ТИНРО
Results of the salmon fishery in Khabarovsk Region in 2023 and the reasons for deviations of actual catches from predicted ones are analyzed. The largest errors of the forecast were associated with low accuracy of estimates for the salmon parents and ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

How Fishery Collapses: The Case of Lepidopus caudatus (Pisces: Trichiuridae) in the Strait of Sicily (Central Mediterranean)

Frontiers in Marine Science, 2021
The silver scabbardfish Lepidopus caudatus is a mesopelagic species living on the shelf and slope down to 600 m in temperate seas all around the world. In the Mediterranean, the species is caught mainly by longlines with a marked seasonality.

The Value of Information in a Congested Fishery [PDF]

, 2023
Congestion can reduce the value of a fishery, resulting in a lower total catch for the same amount of labor, fuel, and equipment expended in fishing activities.
