Tuna Purse Seine Shooting Operation Technique of R/V Nippon Maru [PDF]

open access: yes, 2003
The fisheries technical assistances by Japan Marine Fisheries Resource Research Center (JAMARC) to Southeast Asian Fisheries Development Center (SEAFDEC/TD) to develop tuna purse seine in the Southeast Asia Region, had been carries out for 10 years.

Identification of wage distribution and wage gaps for purse seine crew members

open access: yesDepik Jurnal
Even though the government has established regulations regarding wages, the reality is that the wages received by crew members of fishing vessels are still not in accordance with regulations.

Interactions between small cetaceans and the purse-seine fishery in western Portuguese waters

open access: yesScientia Marina, 2007
Marine mammal interactions with Portuguese purse-seine fisheries operating in four different ports (Figueira da Foz, Sesimbra, Setúbal, Sines) were studied (July-October 2003).

High‐Performance Bio‐Based Epoxy Vitrimers and Composites: Synergizing Robustness and Reprocessability via Fractional Free Volume Regulation

open access: yesAdvanced Science, EarlyView.
In this work, two bio‐based epoxy monomers were designed to tune the dynamic network of a rigid–flexible hybrid epoxy through free‐volume control, achieving a synergy among high free volume, high cross‐linking density, and segmental mobility while balancing strength and toughness.

A Prediction of the Shooting Trajectory for a Tuna Purse Seine Using the Double Deep Q-Network (DDQN) Algorithm

open access: yesJournal of Marine Science and Engineering
The purse seine is a fishing method in which a net is used to encircle a fish school, capturing isolated fish by tightening a purse line at the bottom of the net.

Liquid‐Metal Interfacial Chemistry for Crystal and Defect Engineering in Two‐Dimensional Post‐Transition‐Metal Materials

open access: yesAdvanced Science, EarlyView.
Liquid‐metal interfaces provide dynamic reaction environments in which crystal growth, composition, and defect formation are intrinsically coupled. This Review reveals how interfacial oxidation, alloy thermodynamics, elemental migration, atmosphere, and processing govern defects in 2D post‐transition‐metal materials, and how these defects can be ...

Observation Report on Tuna Purse Seine fFshing Operation in Eastern Indian Ocean On-board R/V Nippon Maru [PDF]

open access: yes, 2007
Tunas frozen are one of the major imported marine fish in the Southeast Asia region. More than 400,000 tons, cost 550,000 U S. Dollar, had been imported in 1997 (Fisheries Statistic Bulletin of South China Sea region, SEAFDEC 1997).

Effects on individual level behaviour in mackerel (Scomber scombrus) of sub-lethal capture related stressors: Crowding and hypoxia.

open access: yesPLoS ONE, 2019
Stress to fish during harvest in wild capture fisheries is known to negatively influence subsequent survival in catches that are released. Therefore, if fisheries are to be conducted sustainably, there is a need to promote good fish welfare during the ...

Wetting‐Driven Transfer of Flexible Ultra‐Thin Temperature Sensors

open access: yesAdvanced Electronic Materials, EarlyView.
A wetting‐driven transfer approach enables ultra‐thin temperature sensors to be transferred from a super‐hydrophilic donor substrate onto rigid, curved, and biological receiver substrates. By combining controlled wetting with a conformal Parylene carrier layer, the method preserves stable thermal sensing performance while expanding the integration of ...

Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...
