Octopuses are generally characterised by rapid non-asymptotic growth, with high individual variability. However, in situ octopus growth is not well understood. The lack of an ageing method has resulted the majority our understanding coming from laboratory studies. Despite being applicable to cephalopods, Modal Progression Analysis (MPA) length–frequency data most common for examining growth. Recently, counting increments beaks and vestigial shells, quantifying lipofuscin brain tissue, have...
Abstract Fisheries have had major negative impacts on marine ecosystems, and effective fisheries management governance are needed to achieve sustainable fisheries, biodiversity conservation goals thus good ecosystem status. To date, the IndiSeas programme (Indicators for Seas) has focussed assessing ecological of fishing at scale using indicators. Here, we explore ‘Management Effectiveness’ ‘Governance Quality’ relate this health We developed a dedicated expert survey, focused level, with...
FISHGLOB brings together experts in, and users of, fish monitoring data to support biodiversity research conservation across oceans.
Abstract Fisheries managers are in need of quantitative tools to inform decisions regarding selection robust management practices, prioritising research gaps and stocks focus on, particularly where there limited resources or data. To support these decisions, the use Management Strategy Evaluation (MSE), that is, closed loop simulation‐testing procedures, is widely regarded as best practice. However, applying MSE time‐ computationally intensive, requires highly skilled expertise processes for...
This study constitutes a first contribution to the knowledge of ecology decapod crustaceans in waters off Guinea-Bissau. Samples were collected during survey undertaken between October and November 2008. A total 122 species identified. Results showed an increase biomass abundance with depth, reaching maxima values 200–500 m depth stratum but decreasing at depths over 500 m. Average diversity by strata increased maximum deep slope. Seven main assemblages identified: five primarily associated...
Glucocorticoids are pleiotropic steroid hormones mediating redistribution of energy. They induce breakdown glycogen stores and consequent plasma hyperglycaemia after stressful situations. Glucocorticoid actions in most vertebrate species exerted by cortisol corticosterone. However, 1α-hydroxycorticosterone is the dominant corticosteroid hormone elasmobranchs, though its effects as a glucocorticoid unknown. Here we demonstrate, using ultra-performance liquid chromatography coupled to tandem...
Deep-sea ecosystems of the Iberian margin have been widely impacted over past decades, but limited knowledge on their biodiversity and functioning limits our ability to contribute conservation. So far, in Gulf Cadiz, research has mostly focused megabenthic assemblages associated mud volcanoes. However, several other geomorphological structures remained unexplored. Here, by means a quantitative analysis 17 video transects conducted between 220 980 m depth, we investigated canyons, contouritic...
A quantitative study of the lipofuscin content was carried out by image analysis in brains known-age, pond-reared Penaeus japonicus (Crustacea, Decapoda) with aim assessing applicability technique as an estimator physiological age penaeids. With this purpose, three distinct measurements levels (% area fraction, granule density and mean size) were recorded ten sections olfactory lobe cell mass (OLCM) per animal. The based on autofluorescence emitted pigment, which accentuates contrast between...
