Estimating Queen Conch (Strombus gigas) home ranges using acoustic telemetry: implications for the design of marine fishery reserves [PDF]

, 2003
Marine reserves (MRs) may function as a vital tool in the conservation and management of marine resources if source populations are managed for the benefit of those downstream.

Shellfish subsidies along the Pacific coast of North America

Ecography, Volume 43, Issue 5, Page 668-681, May 2020., 2020
Spatial subsidies are associated with pronounced ecosystem responses, as nutrients cross ecological boundaries and cascade through food webs. While the importance of subsidies is known, the role of shellfish, specifically molluscs, as a marine subsidy has not been formally described. Focusing primarily on the Pacific coast of North America, we identify

ORGANOGÉNESIS LARVARIA DE Strombus gigas (MESOGASTROPODA: STROMBIDAE) EN EL ARRECIFE ALACRANES DURANTE EL PERIODO MÁXIMO DE SU ÉPOCA REPRODUCTIVA

Ecosistemas y Recursos Agropecuarios, 2014
Con el fin de describir el desarrollo ontogenético de las larvas de Strombus gigas se recolectaron masas de huevos del medio natural y se cultivaron bajo condiciones de laboratorio durante mayo, junio y julio, correspondientes al máximo de la época ...

Precarious livelihoods: Examining the intersection of fish work and ecological change in coastal Jamaica

People and Nature, Volume 2, Issue 1, Page 152-162, March 2020., 2020
Abstract Precarity has not been applied in the context of fisheries‐based work, even as working conditions in fisheries are emerging to be a real issue. There has been limited analysis of fish work outside the media spotlight or how changing ecological and biophysical conditions (e.g.

Microindentation behavior of the shell of the conch Strombus gigas

Microscopy and Microanalysis, 2001
Abstract Microindentation using a hard indentor is a very useful tool to probe the local mechanical properties (plastic flow, fracture, toughness, creep, etc.) of hard solids. We have used a depth sensitive indentation (DSI) version of this technique to study the shell of the conch Strombus gigas.In particular, we prepared polished ...

Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

Larval Diel Vertical Migration of the Marine Gastropod Kelletia kelletii (Forbes, 1850)

Journal of Marine Sciences, Volume 2012, Issue 1, 2012., 2012
Documenting larval behavior is critical for building an understanding of larval dispersal dynamics and resultant population connectivity. Nocturnal diel vertical migration (DVM), a daily migration towards the surface of the water column at night and downward during the day, can profoundly influence dispersal outcomes.

Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Reviewing the Effects of Ocean Acidification on Sexual Reproduction and Early Life History Stages of Reef‐Building Corals

Journal of Marine Sciences, Volume 2011, Issue 1, 2011., 2011
Ocean acidification (OA) is a relatively young yet rapidly developing scientific field. Assessing the potential response(s) of marine organisms to projected near‐future OA scenarios has been at the forefront of scientific research, with a focus on ecosystems (e.g., coral reefs) and processes (e.g., calcification) that are deemed particularly vulnerable.

Conch, Cooperatives, and Conflict: Conservation and Resistance in the Banco Chinchorro Biosphere Reserve

Conservation & Society, 2014
In theory, biosphere reserves link biodiversity conservation with development, primarily through sustainable resource utilisation, and alternative, conservation-compatible economies in the buffer and transition zones outside the core area.
