European Shark Fisheries: A Preliminary Investigation into Fisheries, Conversion Factors, Trade Products, Markets and Management Measures [PDF]

, 2007
Recommends new regulations to prevent shark finning -- an illegal practice in which a shark's fins are removed and its carcass dumped at sea -- and stresses the urgent need for effective shark conservation ...

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

Advanced Science, EarlyView.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Philippine small pelagic fisheries and their management

Aquaculture Research, 1990
. A sampling survey of Philippine small pelagic fisheries was undertaken between 1987 and 1988 at eight sites in the Philippines. A description is given of the different fishing methods and estimates are made of catch per unit of effort and catch composition.

Re-estimation of small-scale fishery catches for U.S. flag-associated island areas in the western Pacific: the last 50 years [PDF]

, 2007
Nearshore fisheries in the tropical Pacific play an important role, both culturally and as a reliable source of food security, but often remain under-reported in statistics, leading to undervaluation of their importance to communities.

Self‐Sustaining Piezozyme Platform for Antifouling via Mechanically Triggered Enzymatic Cascade

Advanced Science, EarlyView.
Wave‐powered CeO2/g‐C3N4 piezozyme coating converts ocean motion into an enzymatic H2O2‐to‐ROS cascade, realizing 180‐day eco‐friendly marine antifouling. ABSTRACT Harnessing ubiquitous mechanical energy for catalytic activation offers an emerging pathway toward self‐sustaining environmental protection systems.

On the Discorhabdins Leading to the Aleutianamine Ring System: A One‐Step in Situ Transformation Characterized Through Computational and Experimental Studies and Its Implications on Biosynthesis, Synthesis, and Pharmacology

Angewandte Chemie, EarlyView.
The thiocarbenium ion rearrangement of 3‐dihydrodisorhabdin B greatly increases the recovery of aleutianamine from Latrunculia spp., a pyrroloiminoquinone natural product with potent activity against drug‐resistant cancers, collected from the deep‐ocean along the Aleutian Islands.

Biodiversity in the bycatch community of Chinese tuna longline fisheries in the Pacific Ocean

Global Ecology and Conservation, 2020
The biodiversity of the bycatch community in tuna longline fisheries has historically been under-studied. In this study, observer data from 9744 sets of Chinese tuna longline fisheries were used to estimate the biodiversity of the bycatch by applying ...

3D visualization for pelagic fisheries research and assessment [PDF]

ICES Journal of Marine Science, 2002
Traditional acoustic approaches to the estimation of fish biomass have relied upon single-beam echo sounders that sample a relatively small volume of the water column within the survey area. Mean transect values, after bottom removal, are extrapolated to provide an estimate of number or biomass within a survey area.

Longline-caught blue shark (Prionace glauca): factors affecting the numbers available for live release* [PDF]

, 2005
The blue shark (Prionace glauca) is an oceanic species that occurs in temperate and tropical waters around the globe (Robins and Ray, 1986). This species is a major bycatch of pelagic longline fleets that operate to supply the world’s growing demand for

RENAL‐CHIP: Rejection Evaluation via Non‐Invasive Analysis of Circulating Podocytes With Herringbone‐Chip Isolation Platform

Advanced Science, EarlyView.
RENAL‐CHIP converts 1 mL of peripheral blood into a biopsy‐equivalent readout of renal‐allograft fate. By magnetic capture and release of donor‐derived circulating podocytes through a herringbone microfluidic chip, 84% capture, 96% release and single‐cell RNA evidence of rejection‐specific immunity are achieved.
