An ecological niche modelling (ENM) approach was used to predict the potential feeding and spawning habitats of small (5–25 kg, only feeding) large (>25 kg) Atlantic bluefin tuna (ABFT), Thunnus thynnus, in Mediterranean Sea, North Gulf Mexico. The ENM built bridging knowledge on traits ABFT (e.g. temperature tolerance, mobility, strategy) with patterns selected environmental variables (chlorophyll-a fronts concentration, sea surface current temperature, height anomaly) that were identified...
Blue shark ( Prionace glauca ) is amongst the most abundant species in international trade, however this highly migratory has little effective management and need for spatio-temporal strategies increases, possibly involving vulnerable stage or sex classes. We combined 265,595 blue observations (capture satellite tag) with environmental data to present first global-scale analysis of species’ habitat preferences five size classes (small juveniles, large juvenile males females, adult females)....
The histological analysis of eastern Atlantic bluefin tuna Thunnus thynnus ovaries caught from February to September 1999–2000, made it possible distinguish the presence seven oocyte developmental stages and allowed characterization six time‐dependent ovary maturity stages. mature (fork length, L F ≥ 110 cm) were non‐active August (spent period) March (quiescent when they contained only perinucleolar‐stage oocytes. Ovary development started in April early May (recrudescent with appearance...
The ovaries of 501 female eastern Atlantic bluefin tuna (Thunnus thynnus Linnaeus, 1758) captured in the Mediterranean Sea from May to September between 1998 and 2004 were analysed histologically. Body size at median sexual maturity (L50) was 103.6 cm fork length (FL), while 100% reached above 135 FL. age analysis, based on count translucent zones first spiniform ray dorsal fin, showed that most specimens with FL = L50 3 years old 4 5 years. reported evidence indicates for stock, females...
The objective of the study was to describe biometry Mediterranean bluefin tuna, Thunnus thynnus, biology which is not yet well understood. A total 504 specimens collected from 1998 2005 in central part basin. They were sexed and measured; fork lengths (FL) ranged 51.0 255.0 cm while body weights (W) 2.6 247.0 kg. first spiniform ray (spine) dorsal fin removed cross-sectioned near condyle base order count annuli for age estimation. regression coefficient (b) female FL–W relationship...
An efficient and adaptive strategy within the EU Marine Spatial Planning Directive has to manage existing increasing conflicts between human uses habitat conservation in coastal-marine areas. Among different activities developed along coasts, aquaculture occupies a primary role. In this context, aims of research have been: (1) propose conceptual model suitable for marine spatial planning; (2) collect integrate indicators useful characterization study area terms socio-ecological-economic...
Abstract One of the major gaps in knowledge sea turtle population dynamics is survival probability, particular juveniles, which represent bulk and whose has greatest effect on growth. global threats to turtles incidental bycatch, although not all animals die process. This particularly acute for loggerhead ( Caretta caretta ). Here fisheries‐dependent monitoring used seek insights into patterns at multiple Mediterranean foraging areas: north south Adriatic, Ionian, Tunisian shelf. Annual...
This study provided a preliminary framework for the effects of Origanum vulgare L. essential oil (EO) on sea bass (Dicentrarchus labrax) health status over 60-day feeding trial. Fish were fed twice day until apparent satiety with three different diets: control diet (CD), and two experimental diets supplemented 100 (D100) 200 (D200) ppm oregano EO. No mortality was observed in each treatment. Feeding D100 resulted high growth performances better food conversion protein efficiency ratios....
The effects of different stressors on the atretic degeneration ovarian vitellogenic follicles, as well mass, were examined in female Atlantic bluefin tuna, Thunnus thynnus (L.), from Mediterranean Sea. taken into consideration short-term starvation (up to 14 days), long-term cage rearing (1 year) and crowding-induced severe panic frenzy. Wild-caught individuals used a control group. Fish subjected either frenzy or exhibited decrease gonad mass had significantly higher intensity α atresia...
Seasonal changes of testicular activity the swordfish Xiphias gladius and correlations plasma levels testosterone (T) 11‐ketotestosterone (11‐KT) with proliferation apoptosis germ cells, determined, respectively, monoclonal antibodies against proliferating cell nuclear antigen terminal deoxynucleotidyl transferase‐mediated d’UTP nick end labelling, are described. Three phases reproductive cycle were found: active spermatogenic (May), spawning (June to July) spent (August September) stages....
Seahorses are considered a flagship species for conservation efforts and due to their status, improving knowledge on dietary composition while applying non-invasive approach, could be useful. Using Hippocampus guttulatus as case study, the present study represents pioneering research into investigating diet of seahorses by NGS-based DNA metabarcoding fecal samples. The developed tested protocol during feeding trials where captive were fed known composition; process was subsequently applied...
The localization and characterization of oligosaccharide sequences in the cat testis was investigated using 12 lectins combination with beta-elimination reaction, N-Glycosidase F sialidase digestion. Leydig cells expressed O-linked glycans terminal alphaGalNAc (HPA reactivity) N-glycans terminal/internal alphaMan (Con A affinity). basement membrane showed Neu5Acalpha2,6Gal/GalNAc, Galbeta1,3GalNAc, alpha/betaGalNAc, GlcNAc (SNA, PNA, HPA, SBA, GSA II oligosaccharides, Galbeta1,4GlcNAc...
The presence of non-reproductive Atlantic bluefin tuna Thunnus thynnus females in the Mediterranean Sea was investigated through histological analysis gonads. Three hundred and twenty-six ovary samples were collected from adults captured at different locations during reproductive seasons between 1998 2008. Only three specimens considered to be a state: two them reabsorbing state showing ovaries with early vitellogenic oocytes extensive alpha beta atresia follicles; third showed gonads...
A study was conducted from 1998 to 2001 on blue shark (Prionace glauca) by-catch of the Italian and Greek surface-drifting swordfish long-line fisheries in Mediterranean Sea. The focus examining whether catches are related some environmental, spatial, temporal or operational parameters what extent, applying generalized linear model (GLM) approaches. Analyses indicated that most appropriate for dataset Delta-lognormal model, which is a binomial error distribution probability non-zero catch...
