Side effects for batoids’ conservation in the vacuum of fishery management

Marine and Fishery Sciences, 2023
A shift verified in batoid landings by artisanal fisheries during 2017-2021 is interpreted as a potential consequence of legal measures set by the Brazilian government in 2014.

All‐Amyloid Functional Coacervates

Advanced Materials, EarlyView.
This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

The artisanal elasmobranch fishery on the east coast of Baja California, Mexico: Characteristics and management considerations

Ciencias Marinas, 2009
The Mexican elasmobranch fishery ranks among the most important in the world, but details associated with fishing effort and species composition are generally unavailable, particularly for the extensive artisanal fishery. Seasonal surveys were conducted

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Dynamic shifts and a drastic decline in reported landings for southern Gulf of St. Lawrence commercial clam fisheries over the past two decades

FACETS
Clams constitute an important socioeconomic and Indigenous resource in the southern Gulf of St. Lawrence (sGSL); however, detailed analyses of commercial clam fisheries are outdated. I provide a synthesis of sGSL clam landings from 2003 to 2022.

Modelling and Forecasting the Catch of the Scads (Decapterus macrosoma, Decapterus russellii) in the Javanese Purse Seine Fishery Using ARIMA Time Series Models

Asian Fisheries Science, 2000
The standard of living of the purse seine fishers operating in the northern coast of the Java Island is closely related to scad resources. Scads landings of the semi-industrial purseseine fishery were analyzed using Seasonal Auto Regressive ...

Evidence of climate-driven regime shifts in Adriatic Sea fisheries

Scientia Marina
Marine ecosystems can undergo abrupt changes due to the interaction between human activities and environmental drivers. These changes can result in a non-linear response, causing the system to shift to a different state, known as a regime shift.

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Changes in fishing production in the northern Brazil [PDF]

Anais da Academia Brasileira de Ciências
This study analyzed temporal changes in fishery production along the northern coast of Brazil to assess evidence of fishing down marine food webs. Landings data from Pará State between 1997 and 2007 were used to evaluate variations in catch composition ...
