Proximate and Mineral Composition of the Long Spined Sea Urchin (Diadema setosum) Roe

Borneo Journal of Sciences and Technology, 2023
Gonad of sea urchin is considered as food delicacy in many parts of the world due to high nutrition and mineral contents. Several species of sea urchins are available in Malaysia and reported from different habitat, including seagrass beds, coastal breakwater, coral reefs and other ecologically important habitats.

Diversity of long-spined sea urchins (Diadema spp.) in the Indo-Malay archipelago

Arxius de Miscel-lània Zoològica
Long-spined sea urchin species (genus Diadema) are important to the ecology of coral-reef ecosystems. The objective of this paper is to inventory Diadema species occurring in the so far under-sampled Indo-Malay archipelago at the core of the tropical ...

Population dynamics and fecundity estimates of Long-spined Black Sea Urchin Diadema savignyi (Audouin, 1890) from the Red Sea, Saudi Arabia. [PDF]

Saudi J Biol Sci, 2022
Sea Urchin is not only the crucial keystone species for the coral reef restoration but also it has antimicrobial and anti-cancer activities. This study undertaken to focus on length weight relationship, size fecundity distribution and the estimation of fecundity from the long-spined Sea Urchin, Diadema savignyi at the coastal water of the middle Red ...

Growth and foraging behavior of hatchery propagated long-spined sea urchins, Diadema antillarum: Implications for aquaculture and restocking

Aquaculture Reports, 2022
Stocking hatchery propagated long-spined sea urchins Diadema antillarum is a priority option for recovery of this keystone herbivore on Caribbean reefs. However, information on captive culture of D.

A Haplotype-Resolved Genome Assembly of the Long-Spined Sea Urchin <i>Diadema antillarum</i>, a Keystone Caribbean Reef Herbivore. [PDF]

Genes (Basel)
Background/Objectives: The long-spined sea urchin Diadema antillarum is a keystone herbivore whose grazing maintains Caribbean coral reefs; basin-wide mass mortalities in 1983–1984 and 2022 have made genomic resources a conservation priority, yet no nuclear genome existed for the species.

Diurnal predators of restocked lab-reared and wild Diadema antillarum near artificial reefs in Saba [PDF]

PeerJ, 2023
The long-spined sea urchin Diadema antillarum controls reef dynamics by grazing on algae and increasing coral recruitment. Populations of Diadema never recovered after a mass-die off in 1983 and 1984, and numbers were further reduced by a more recent die-

Demographic rise of sea urchin Centrostephanus sylviae on Robinson Crusoe and Santa Clara Islands at the Juan Fernandez Archipelago: A biophysical and ecological approach. [PDF]

PLoS ONE
The large increase in the population of long-spined sea urchins (Centrostephanus sylviae) has gained significant attention in the past decade due to the rise in the number of individuals reported as bycatch in Juan Fernandez rock lobster traps (Jasus ...

Impacts of hurricanes and disease on Diadema antillarum in shallow water reef and mangrove locations in St John, USVI. [PDF]

PLoS ONE
The 1983-1984 mortality event of the long-spined sea urchin Diadema antillarum reduced their population by up to 99% and was accompanied by a phase shift from coral dominated to algal dominated reefs in the Caribbean. Modest rebounds of D.

The 2022 Diadema antillarum die-off event: Comparisons with the 1983-1984 mass mortality

Frontiers in Marine Science, 2023
The 1983-1984 die-off of the long-spined sea urchin Diadema antillarum stands out as a catastrophic marine event because of its detrimental effects on Caribbean coral reefs. Without the grazing activities of this key herbivore, turf and macroalgae became
