Seasonal variability of diet and trophic level of the gelatinous predator Pelagia noctiluca (Scyphozoa)

by CERES | Aug 14, 2018 | CERES publications, marine fisheries

By use of a combination of stomach contents, stable isotope (SI) and fatty acid (FA) analyses, we tested the hypothesis that changes in the seasonal dietary sources of P. noctiluca parallel changes in the FA and SI composition. This study also revealed significant...

The Baltic Sea Atlantis: An integrated end-to-end modelling framework evaluating ecosystem-wide effects of human-induced pressures

by CERES | Jul 20, 2018 | CERES publications, CERES Science, marine fisheries

We present a new framework, with a Baltic implementation of the spatially-explicit end-to-end Atlantis ecosystem model linked to two external models, to explore the different pressures on the marine ecosystem. We conclude that the Baltic Atlantis forms an initial...

A Prelimnary Survey on Perception of Turkish Aquaculture Stakeholders on Climate Change – Aquaculture Interactions

by CERES | Jun 30, 2018 | CERES publications, marine aquaculture, marine fisheries

Climate change is expected to have direct and indirect impacts on aquaculture sector. Awareness building and understanding the perceptions of aquaculture stakeholders regarding the impact of climate change on aquaculture are important pillars of developing adaptation...

Successional dynamics of marine fouling hydroids (Cnidaria: Hydrozoa) at a finfish aquaculture facility in the Mediterranean Sea

by CERES | Apr 2, 2018 | CERES publications, marine aquaculture, marine fisheries

Here two experiments, each with 36 panels, tested colonization (factors: depth, season of immersion) and succession (factors: depth, submersion duration) over one year. The results illustrate the potential importance of fouling hydroids and their medusae to the health...

Indicator-Based Geostatistical Models For Mapping Fish Survey Data

by CERES | Feb 19, 2018 | CERES publications, marine aquaculture, marine fisheries

Marine research survey data on fish stocks often show a small proportion of very high-density values, as for many environmental data. This makes the estimation of second-order statistics, such as the variance and the variogram, non-robust. The high fish density values...

Atlantic bluefin tuna spawn at suboptimal temperatures for their offspring

by CERES | Jan 10, 2018 | CERES publications, marine fisheries

In this study we analyse how offspring fitness constrains spawning phenology in a large migratory apex predator, the Atlantic bluefin tuna. The reproductive schedule of Atlantic bluefin tuna varies between spawning sites, suggesting plasticity to local environmental...
