Test of ROV-based harvesting methods for sea urchins and scallops. Part one: Report on Sea Urchin (Kråkebolle) collection trial [PDF]

, 2012
One of the major bottlenecks to the development of a sea urchin industry in Norway is a reliable and economically viable method of collecting urchins. The current trial aimed to test the economic feasibility of fishing commercial quantities of sea urchin

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

The jaws in the jaws: Morphofunctional analysis of the pharyngeal plates of Labrus viridis Linnaeus, 1758 (Teleostei, Labridae)

Journal of Fish Biology, EarlyView.
Abstract Functional morphology highlights the adaptive flexibility of fish feeding strategies across environmental gradients and seasonal variations, providing key insights for the management and conservation of ichthyofaunal communities and their habitats.

The effect of a harmful algal bloom (Karenia selliformis) on the benthic invertebrate community and the sea otter (Enhydra lutris) diet in eastern Hokkaido.

PLoS ONE
In recent decades, the locally extinct sea otter (Enhydra lutris lutris) has been recolonizing the coast of eastern Hokkaido. Their diet includes benthic invertebrates such as bivalves, sea urchins, snails, and chitons.

Profitability and sustainability of sea urchins fishing in Sardinia (Italy)

, 2013
Fishing sea urchins is a traditional activity deeply rooted in several Mediterranean communities. Sea urchin is a basic ingredient of well appreciated typical dishes (e.g., pasta, croutons and pizza), but turnover has not been higher than that of niche ...

Articulated Coralline Algae Provide a Spatial Refuge to Juvenile Sea Urchins from Predatory Crabs

, 2017
Coralline algae provide settlement cues, food, and biotic structure for benthic marine invertebrates in intertidal and subtidal habitats. Here, we present evidence from laboratory experiments that juvenile sea urchins Strongylocentrotus droebachiensis (1.

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

A prickly problem with sea urchins

, 2019
Beneath the waves, once towering kelp beds are collapsing from an unprecedented perfect storm that has been brewing below the surface. First, a massive epidemic wiped out sea stars, then a marine heatwave and El Niño, and now an explosion of sea urchins.

Harbouring the Enemy: Kelp Holdfasts Protect Juvenile Sea Urchins from Predatory Crabs

, 2014
Predation is an important agent of post-settlement mortality of sea urchins that is mediated by the availability and suitability of spatial refuges, particularly during the vulnerable juvenile stage.
