Relative abundance and size composition of subtidal abalone, Haliotis spp., sea urchin, Strongylocentrotus spp., and abundance of sea stars off Fitzgerald marine reserve, September 1993 [PDF]
Data were collected at twenty-six dive stations at seven discrete latitudes along Fitzgerald Marine Reserve (FMR). Dive stations were targeted at three stratified depth zones: shallow (6.1 m), medium (10.7 m), and deep (16.8 m) in six of the seven ...

ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Sea cucumber and sea urchin resources [PDF]
The Andaman and Nicobar Islands offer one of the most suitable habitats for sea cucumbers and sea urchins due to the presence of sheltered bays and lagoons.

ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

ABSTRACT Global dietary guidelines consistently recommend regular seafood consumption to support adequate omega‐3 long‐chain (≥ C20) polyunsaturated fatty acid (n‐3 LC‐PUFA) intake. Most international health authorities advise two servings of seafood per week, including at least one serve of oily fish, to achieve approximately 500 mg/day of combined ...

Multiple Longitudinal Tracts in the Cephalopod Arm Sensorimotor System
Octopuses have a rich behavioral repertoire, coordinating complex movements along the length of an arm. The neural circuits controlling these behaviors are poorly understood. We employ tract‐tracing to investigate longitudinal tracts in the octopus arm.

We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.

Prickleback fishes (Stichaeidae) feed upon diverse diets, spanning carnivory (orange), omnivory (blue), and herbivory (green). We used microCT scanning to explore the functional morphology of the oral jaws and dentition across species and ontogeny. Focal species vary by morphotype and have divergent scaling patterns across diets.
